爱普生晶振型号大全
爱普生晶振型号大全本文由/doc/c510992735.html,整理合成爱普生公司成立于1942年5月，总部位于日本长野县诹访市，是数码映像领域的全球领先企业。
爱普生集团通过富有创新和创造力的文化，提升企业价值，致力于为客户提供数码影像创新技术和解决方案。
爱普生拓优科梦是一家专业从事晶体元件的厂商，爱普生拓优科梦的晶体元器件已以23%的市场占有率位于业界第一。
在2010年晶振全球厂家排名中，占据首位。
爱普生仅此一项水晶振动子行业就能足矣让电子世界的人都敬佩不已。
爱普生晶振以32.768KHZ晶振称霸晶振行业，主要消费在手机，PCB，等电子产品。
同时爱普生以提供原子钟的精准振荡器知名业界。
仅此在音叉振子和振荡器还远远达不到爱普生本身的要求。
他们要求的是在元器件占领NO1。
因此除了KHZ,MHZ的研究发展，另外还发明GHZ 技术，使工艺技术达到人无完人，史前无例，实现以基波方式产生2.5GHz为止高频的表面声波（SAW）元器件。
爱普生拓优科梦把半导体（IC）称之为“产业之米”，并认为晶体元器件更是离不开的“产业之盐”。
将进一步致力于小型、高稳定、高精度晶体元器件的开发，为现有的应用程序以及生活新蓝图开拓广阔前景。
爱普生晶振在KHZ，MHZ,以及GHZ上都有重大突破，使得爱普生拓优科梦的晶体元器件已以23%的市场占有率位于业界第一。
那我们说说爱普生KHZ的产品工艺吧，爱普生KHZ产品分有圆柱DIP和贴片SMD。
KHZ中爱普生是以32.768KHZ最为出名的。
32.768K晶振是一款数字电路板都要使用到的重要部件，有人比喻为电路板的心跳发生器，也就是说心如果停止了跳动，那么电路板也将无法进行稳定的工作了。
32.768K中爱普生C-002RX是一款受欢迎的圆柱音叉晶振，体积只有2*6mm。
与精工的VT-200-F，西铁城的CFS206，KDS的DT-26同体积同参数。
因此说道的四款型号晶振都是可以相互替换使用的。

* 在进入操作设定之前，建议将 TE 位 清 0。 * 在不用该功能的时候，计数器 0，1 可以作为 RAM 来使用，但需要将 TE 和 TIE 清 0。 1)用于固定定时器的递减计数器 0,1
该寄存器用来设定定时器的默认值, 从 0 到 65535。 在写入预设值之前请确认 TE 位 为’0’。 *TE 为‘0’时读出来的值是预设值，‘1’时读出来的值是计数值。 2）TSEL0，TSEL1，TSEL2 这三个位的组合用来设置倒数计数的周期（时钟源）

OverviewThis module is a real-time clock with a serial interface and a built-in crystal oscillator. This module is also equipped with clock and calendar circuits, an automatic leap year compensation function, and a supply voltage detection function.In addition, this module has a 32.768 kHz/1 Hz selectable output function for hardware control that is independent of the RTC circuit.This module is available in a compact SOP 14-pin package (RTC-4543SA) and a thin SOP 18-pin package (RTC-4543SB).4.

Only 24 hours system is supported. • ∗bits. These bits are used as memory.• TM bit. This is a test bit for shipping test. Always clear this bit to “0”.• FDT bit: Supply voltage detection bit• This bit is set to “1” when voltage of 1.7 ±0.3 V or less is detected between V DD and GND. • The FDT bit is cleared if all of the digits up to the year digits are read.• Although this bit can be both read and written, clear this bit to "0" in case of the write cycle.if the supply voltage is lower than the detection voltage value, the FDT bit is set to “1”.7. Description of Operation2) At the first rising edge of the CLK signal, the clock and calendar data are loaded into the shiftregister and the LSB of the seconds digits is output from the DATA pin.3) The remaining seconds, minutes, hour, day of the week, day, month, and year data is shifted out,in sequence and in synchronization with the rising edge of the CLK signal, so that the data isoutput from the DATA pin.The output data is valid until the rising edge of the 52nd clock pulse; even if more than 52 clockpulses are input,the output data does not change.4) If data is required in less than 52 clock pulses, that part of the data can be gotten by setting theCE pin low after the necessary number of clock pulses have been output.Example: If only the data from “seconds” to “day of the week” is needed:After 28 clock pulses, set the CE pin low in order to get the data from “seconds” to “day ofthe week.”5) When performing successive data read operations, a wait (tRCV) is necessary after the CE pinis set low.6) Note that if an update operation (a one-second carry) occurs during a data read operation,the data that is read will have an error of -1 second.7) Complete data read operations within tCE (Max.) = 0.9 seconds, as described earlier.1) RTC 4543 shifts to data input state by condition of WR terminal ="H",CE terminal ="H".2) Writing-data synchronize to a rising edge of CLK, and it inputs into an RTC from LSB of sec.3) Inside counter less than second is reset between falling edges of first CLK from a rising edge of next CLK.And update of Clock register is prohibited by the first falling edge of CLK.4) In writing of data to RTC, all 52 clock is necessary.When CE goes to LOW before the 52 bits transmission is completed, there is the possibilitythat * ,FDT and a year digit were destroyed.If a serial communication break occurs, do verify 8 bits of* bit andFDTbit and year data.5) In a rising edge of 52 clock, all data is written to RTC. Data after 53 bits is ignored.6) When CE goes to LOW, RTC re-starts update.Please finish write access within 0.9 second = tCE (Max.).7) Between write access and read access, recovery timing(tRCV) is necessary.Please do not set the time and date which is non-existence.7-3. Data writes (Divider Reset)After the counter is reset, carries to the seconds digit are halted.After the data write operation,the prohibition on carries to the seconds counter is lifted by setting the CE pin low.Complete data write operations within tCE (Max.) = 0.9 seconds, as described earlier.7-4. FOUT output and 1 Hz carriesDuring a data write operation, because a reset is applied to the Devider counter (from the 128 Hzlevel to the 1 Hz level) after the CE pin goes high during the time between the falling edge of the first clock cycle and the rising edge of the second clock cycle, the length of the first 1 Hz cycle after thedata write operation is 1.0 s +0 / −7.8ms +t CES+t CLK. Subsequent cycles are output at1.0-second intervals.The 1-Hz signal that is output on FOUT is the internal 1-Hz signal with a 15.6-ms shift applied.8. Examples of External Circuits11. Reference DataNote : This data shows values obtained from a sample lot.12. Application notes1) Notes on handlingThis module uses a C-MOS IC to realize low power consumption. Carefully note the following cautions when handling.(1) Static electricityWhile this module has built-in circuitry designed to protect it against electrostatic discharge, the chip could still be damaged bya large discharge of static electricity. Containers used for packing and transport should be constructed of conductive materials.In addition, only soldering irons, measurement circuits, and other such devices which do not leak high voltage should be used with this module, which should also be grounded when such devices are being used.(2) NoiseIf a signal with excessive external noise is applied to the power supply or input pins, the device may malfunction or "latch up."In order to ensure stable operation, connect a filter capacitor (preferably ceramic) of greater that 0.1 µF as close as possible to the power supply pins (between VDD and GNDs). Also, avoid placing any device that generates high level of electronic noise near this module.* Do not connect signal lines to the shaded area in the figure shown in Fig. 1 and, if possible, embed this area in a GND land.(3) Voltage levels of input pinsWhen the input pins are at the mid-level, this will cause increased current consumption and a reduced noise margin, and can impair the functioning of the device. Therefore, try as much as possible to apply the voltage level close to VDD or GND.(4) Handling of unused pinsSince the input impedance of the input pins is extremely high, operating the device with these pins in the open circuit state can lead to unstable voltage level and malfunctions due to noise. Therefore, pull-up or pull-down resistors should be provided for all unused input pins.2) Notes on packaging(1) Soldering heat resistance.If the temperature within the package exceeds +260 °C, the characteristics of the crystal oscillator will be degraded and it may be damaged. The reflow conditions within our reflow profile is recommended. Therefore, always check the mounting temperature and time before mounting this device. Also, check again if the mounting conditions are later changed.* See Fig. 2 profile for our evaluation of Soldering heat resistance for reference.(2) Mounting equipmentWhile this module can be used with general-purpose mounting equipment, the internal crystal oscillator may be damaged in some circumstances, depending on the equipment and conditions. Therefore, be sure to check this. In addition, if the mounting conditions are later changed, the same check should be performed again.(3) Ultrasonic cleaningDepending on the usage conditions, there is a possibility that the crystal oscillator will be damaged by resonance during ultrasonic cleaning. Since the conditions under which ultrasonic cleaning is carried out (the type of cleaner, power level, time, state of the inside of the cleaning vessel, etc.) vary widely, this device is not warranted against damage during ultrasonic cleaning.(4) Mounting orientationThis device can be damaged if it is mounted in the wrong orientation. Always confirm the orientation of the device before mounting.(5) Leakage between pinsLeakage between pins may occur if the power is turned on while the device has condensation or dirt on it. Make sure the device is dry and clean before supplying power to it.Application ManualElectronic devices information on WWW serverDistributor/en/quartz/index.html。
