The hardware design guidelines are similar for this product family. In this document, the MKE17Z256VLL7 device is used for demonstration purposes. Table 1.KE17Z family1.INT: interrupt pin numbers; HD: high drive pin numbersKE17Z MCUs extend Kinetis E family to dual TSI performance and broader scalability. Robust and dual TSI provides high-level stability and accuracy to customer's HMI system. 1 Msps ADC and FlexTimer help build a perfect solution for a simple BLDC motor control system.Following are the general features of the KE17Z series MCUs:•Arm® Cortex®-M0+ core, supports up to 72 MHz frequency, with 2.35 CoreMark/MHz.•Scalable memory up to 256 KB program flash and up to 48 KB SRAM• 5 V power supply ranges from 2.7 V to 5.5 V.•Dual capacitive touch sensing modules offer 2 x 25 ch touch sensing channels supporting both self-cap and mutual cap technologies.•Precision mixed-signal capability with 1x high-speed on-chip analog comparator and 1× 12-bit analog-to-digital converter (ADC) with up to 16 channel analog inputs per module, up to 1 Msps.•Flexible timers including 3 × Flex Timers (FTM) for PWM generation, offering up to 8 standard PWM channelsThis document describes the following module and provides appropriate hardware design related recommendations:•Power Supply•Clock Module•Reset Circuit•Debugging and Programming Interface •Touch Sensing interface (TSI)•ADC Input Circuit•Digital GPIO and unused pin •General Board Layout GuidelinesA general schematic example is shown in the following figure.Figure 1.X-KE17Z-TSI-EVB schematic example1.1Related documentationThe table below lists and explains the additional documents and resources that you can refer to for more information on KE17Z MCUs. Some of the documents listed below may be available only under a non-disclosure agreement (NDA). To request access to these documents, contact your local field applications engineer (FAE) or sales representative.Table 2.Related documentationTable continues on the next page...Table 2.Related documentation (continued)Chapter 2Power SupplyThe power supply of KE17Z ranges from 2.7 V to 5.5 V, the detailed operating requirements are listed below. Note that the difference between VDD (digital power supply) and VDDA (analog power supply) cannot exceed 0.1 V, so it is recommended to connect VDD and VDDA directly in practice. Also, the power supply ramp up rate should be limited within 100 V/ms.Table 3.Power supplyThe decoupling capacitors (100 nF as shown in the figure below) are required to filter out the system noise. Figure below shows examples of decoupling capacitors on the schematic, at least one decoupling capacitor per power pin is recommended. On PCB layout level, all decoupling capacitors should be placed as close as possible to each of their respective power supply pin; the ground side of the decoupling capacitor should have a via to the pad which goes directly down to the ground plane. The decoupling capacitors should not route to the power plane through a long trace. The types and values of the decoupling capacitor depend on the noise level and frequency. The typical value is usually in the range of 0.01 μF to 0.1 μF.The bulk capacitor (10 μF as shown in the figure below) acts as a local power supply to the power pin, its typical value is 10 μF.Power SupplyChapter 3Clock ModuleThe KE17Z has the following clock sources:•Fast internal reference clock (FIRC): 48 MHz high-accuracy (up to ±1%) fast internal reference clock (FIRC) for normal Run as the default system clock source after reset.•Slow internal reference clock (SIRC): 8 MHz/2 MHz.•LPFLL: Supports only up to 72 MHz•LPO128K: 128 KHz always on internal low-power oscillator clock, for WDOG, LPTMR, EWM, PORT Control.•External square wave input: Up to 60 MHz DC external square wave input clock•External oscillator clock (OSC): high range 4 - 40 MHz (with low power or high gain mode) and low range 32 - 40 kHz (with high-gain mode only)3.1External oscillator circuit designThe EXTAL and XTAL pins provide the interface for a Crystal oscillator. EXTAL is the input to the crystal oscillator amplifier. XTAL is the output of the crystal oscillator amplifier. The pierce oscillator provides a robust, low-noise, and low-power external clock source. It is designed for optimal start-up margin with typical crystal oscillators. KE17Z supports two ranges of external oscillator:•high-range: 4 - 40 MHz (with low-power or high-gain mode)Table 4.External crystal/resonator connections•low-range: 32 - 40 kHz (with high-gain mode only)The typical circuit design of the external oscillator is shown in the figure below. For the low-power use case, the low-power oscillator mode is recommended, as shown in Diagram 2, thus the 1 Mohm R F (feedback resistor) is not needed in this case. For noise use case, the high-gain oscillator is preferred as shown in Diagram 3. The user needs to add 1 Mohm R F (feedback resistor), also the use needs to double check with the crystal vendor about the exact value of R S (series resistor). The load capacitors of C1 and C2 must be provided by external capacitors and their load capacitance depends on the crystal or resonator manufacturers' recommendation. Check the crystal datasheet for the recommended values. And, also consider the parasitic capacitance of package and board.Figure 2.Crystal circuit design – Diagram 2Clock ModuleFigure 3.Crystal circuit design – Diagram 33.2EMC considerationsAs the clock circuit is very sensitive to the noise, you need to pay attention to the following guidelines on PCB layout:Avoid placing any signal traces close to the clock circuit.Place the external crystal to the EXTAL/XTAL pins as close as possible.A ground area should be placed under the crystal oscillator area. This ground guard ring must be clean ground. This means that no current from and to other devices should be flowing through the guard ring. This guard ring should be connected to VSS with a short trace. Never connect the ground guard ring to any other ground signal on the board. Also avoid implementing ground loops. The following figure shows the recommended placement and routing for the oscillator layout.Chapter 4Reset CircuitResetting the MCU provides a way to start processing from a known set of initial conditions. System reset begins with the on-chip regulator in full regulation and system clocking generation from an internal reference.For all reset sources, the RESET_B pin is driven low by the MCU for at least 128 bus clock cycles and until the flash memory initialization is completed. After flash memory initialization completes, the RESET_B pin is released and the internal chip reset is deasserted. Keeping the RESET_B pin asserted externally delays the negation of the internal chip reset. The detailed boot sequence is shown in the figure above.As shown in the schematic example figure, the reset circuit consists of an external pullup resistor added between reset pin to power supply, a capacitor between the reset pin to ground, and an optional reset button.Debug and Programming InterfaceThis MCU uses the standard Arm SWD interface protocol as shown in the following figure. While pull-up or pull-down resistors are not required (SWD_DIO has an internal pull-up and SWD_CLK has an internal pull-down), external 10 kΩ pull resistors are recommended for system robustness. The RESET_b pin recommendations mentioned above must also be considered.Touch Sensing InputTouch sensing input (TSI) provides touch sensing detection on capacitive touch sensors. The external capacitive touch sensor is typically formed on PCB and the sensor electrodes are connected to TSI input channels through the I/O pins in the device.KE17Z TSI supports dual TSI modules and each TSI module supports two kinds of touch sensing method, the self-capacitive mode and the mutual-capacitive mode.6.1TSI self-capacitive mode design considerationsThe self-capacitive mode requires single pin for each touch sensor and measures the capacitance on an electrode connected to a single TSI channel. It then converts the capacitance into a digital count by driving average current on the electrode and measuring the charge/discharge times.Figure 4.PCB layout of the electrode shapes for TSI self-capacitive modeTo maximize the electrodes area from the capacitor plates, it is recommended that the size of the electrode is similar to a human finger (10×10 mm is considered a good size).6.2TSI mutual capacitive mode design considerationsMutual capacitive mode measures the capacitance between two electrodes connected to two TSI channels. One of the TSI channels is used as transmit (TX) channel and the other one is used as receive (RX) channel.Figure below shows the connections of TSI channel in mutual-capacitive mode.Touch Sensing Input6.3PCB layout of the electrode shapes for TSI mutual capacitive modeThe following figure is the recommended mutual key shape. Note that the number of fingers has much impact on the touch sensitivity. In general, more fingers result in stronger noise immunity but less touch sensitivity. Customer should select the right finger numbers for the thickness of touch overlay. For example, if the touch overlay is 3 mm in thickness, 4 fingers is the best choice. If the touch overlay is 2 mm in thickness, 5 fingers are ok.For the detailed TSI design guide, see KE15ZTSIUG, KE15Z Touch Sensing Interface User Guide.Chapter 7ADC Input CircuitEach ADC input must have an RC filter as shown in the following figure. The maximum value of the resistor must be less than R S (maximum 5 kohm as shown in the table below) if fast sampling and high resolution are required. The value of C must be chosen to ensure that the RC time constant is very small compared to the sample period. For example, the typical filter resistor is 100 ohm, together with the 220 pF capacitor, the low-pass cutoff frequency is 7.238 MHz.The specifications of ADC input impedance and operating conditions are shown below for your reference.Table 5.12-bit ADC operating conditionsTable continues on the next page...ADC Input Circuit Table 5.12-bit ADC operating conditions (continued)1.Typical values assume V DDA = 5 V, Temp = 25 °C, f ADCK = 40 MHz, unless otherwise stated. Typical values are for referenceonly, and are not tested in production.2.DC potential difference.3.For packages without dedicated V REFH and V REFL pins, V REFH is internally tied to V DDA, and V REFL is internally tied to V SSA.4.Clock and compare cycle need to be set according the guidelines in the block guide.5.ADC conversion will become less reliable above maximum frequency.6.When using ADC hardware averaging, refer to the device Reference Manual to determine the most appropriate settingfor AVGS.7.Max ADC conversion rate of 1200 Ksps is with 10-bit modeDigital GPIO and Unused PinFor the detailed IO pin mux functions and pinout, see "Section 4 Pinouts" in KE1xZP100M72SF1, Kinetis KE17Z/13Z/12Z with up to 256 KB Flash Data Sheet.Regarding IO drive strength, there are 8 high drive pins with 20 mA drive strength. These high drive pins are: PTD0, PTD1, PTD15, PTD16, PTB4, PTB5, PTE0, and PTE1. In practice, keep the total output current for all ports under 100 mA as specified in Data Sheet.Regarding the switching terms, the minimum positive voltage applied to the input which will be accepted by the device as a logic high (V IH) is 0.7*VDD, and the maximum positive voltage applied to the input which will be accepted by the device as a logic low (V IL) is 0.3*VDD. They are also listed in the Data Sheet.On reset, the most digital GPIOs (excepting debugging pins) are Disabled/Hi-z by default.8.1EMC considerationsThe general IO block diagram is shown below. As port E supports the glitch filter feature, it’s recommended to use port E pins as the digital input pins, with better noise immunity by enabling the glitch filter feature.There is a pair of ESD protecting diodes on each IO pin, so the user doesn’t need to add the extra ESD diode.8.2NMI pin considerationsAfter reset, the default function of PTD3 pin is NMI (no mask interrupt, low active). The software can configure the pin as other functions only after the reset completes and begins to execute the application code. Therefore, note that the NMI pin cannot be low level at reset, otherwise the code will be stuck in NMI interrupt service routine. In practice, keep the NMI pin unused and unconnected (or pull up with 4.7 kohm resistor) if there is enough pin to use.8.3Unused pin considerationsIn order to improve EMC noise immunity and reduce the current consumption, the used pins are suggested to keep unconnected and the software should configure these unused pins as DISABLED, which is the default pin status after reset.General Board Layout GuidelinesFor the detailed general board layout guidelines, see "Chapter 10" in AN5426, Hardware Design Guidelines for S32K1xx Microcontrollers.Appendix ARevision HistoryThe table below summarizes the revisions to this document.

System Clock SourcesThe C8051F326 device installed on the target board features a calibrated programmable internal oscillator which is enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of 1.5MHz (±1.5%) by default but may be configured by software to operate at other frequencies. Therefore, in many applica-tions an external oscillator is not required. However, if you wish to operate the C8051F326 device at a frequency not available with the internal oscillator, an external CMOS oscillator may be used. Refer to the C8051F326/7 datasheet for more information on configuring the system clock source.The target board is designed to facilitate the installation of an external CMOS oscillator. Remove shorting block at header J10 and connect the oscillator output to the header. Refer to the C8051F326/7 datasheet for more informa-tion on the use of external oscillators.4.2. Switches and LEDsThree switches are provided on the target board. Switch S1 is connected to the /RST pin of the C8051F326. Press-ing S1 puts the device into its hardware-reset state. Switches S2 and S3 are connected to the C8051F326’s gen-eral purpose I/O (GPIO) pins through headers. Pressing S2 or S3 generates a logic low signal on the port pin. Remove the shorting blocks from the header to disconnect S2 and S3 from the port pins. The port pin signals are also routed to pins on the J1 I/O connector. See Table1 for the port pins and headers corresponding to each switch.Three LEDs are also provided on the target board. The red LED labeled PWR LED is used to indicate a power con-nection to the target board. The green surface mount LEDs labeled with port pin names are connected to the C8051F326’s GPIO pins through headers. Remove the shorting blocks from the header to disconnect the LEDs from the port pin. The port pin signals are also routed to pins on the J1 I/O connector. See Table1 for the port pins and headers corresponding to each LED.Table 1.
