In a latchup condition, supply current can increase dramatically and may destroy semiconductor elements. In using semi-conductor devices, always take sufficient care to avoid exceeding maximum ratings.Also care must be taken when power to analog systems is switched on or off, to ensure that the analog power supply (AV CC, AVRH) , analog input and dedicated power supply for the high current output buffer pins (DV CC) do not exceed the digital power supply (V CC) .Once the digital power supply (V CC) is switched on, the analog power (AV CC,AVRH) and dedicated power supply for the high current output buffer pins (DV CC) may be turned on in any sequence.•Stable supply voltageEven within the warranted operating range of V CC supply voltage, sudden fluctuations in supply voltage can cause abnormal operation. The recommended stability for ripple fluctuations (P-P values) at commercial fre-quencies (50 Hz to 60 Hz) should be within 10% of the standard V CC value, and voltage fluctuations that occur during switching of power supplies etc. should be limited to transient fluctuation rates of 0.1 V/ms or less.•Power-on proceduresIn order to prevent abnormal operation of the internal built-in step-down circuits, voltage rise time during power-on should be attained within 50 µs (0.2 V to 2.7 V) .•Treatment of unused pinsIf unused input pins are left open, they may cause abnormal operation or latchup which may lead to permanent damage to the semiconductor. Any such pins should be pulled up or pulled down through resistance of at least2 kΩ.Any unused input/output pins should be left open in output status, or if found set to input status, they should be treated in the same way as input pins.Any unused output pins should be left open.•Treatment of A/D converter power supply pinsEven if the A/D converter is not used, pins should be connected so that AV CC= V CC, and AV SS= AVRH = V SS.•Use of external clock signalsEven when an external clock is used, a stabilization period is required following a power-on reset or release from sub clock mode or stop mode. Also, when an external clock is used it should drive only the X0 pin and the•Power supply pinsDevices are designed to prevent problems such as latchup when multiple V CC and V SS supply pins are used, by providing internal connections between pins having the same potential. However, in order to reduce unwanted radiation, and to prevent abnormal operation of strobe signals due to rise in ground level, and to maintain total output current ratings, all such pins should always be connected externally to power supplies and ground.As shown in figure below, all V CC power supply pins must have the same potential. All V SS power supply pins should be handled in the same way. If there are multiple V CC or V SS systems, the device will not operate properlyIn addition, care must be given to connecting the V CC and V SS pins of this device to a current source with as little impedance as possible. It is recommended that a bypass capacitor of 1.0 µF be connected between V CC and V SS as close to the pins as possible.•Proper sequence of A/D converter power supply analog inputA/D converter power (AV CC, AVRH) and analog input (AN0-AN7) must be applied after the digital power supply (V CC) is switched on. When power is shut off, the A/D converter power supply and analog input must be cut off before the digital power supply is switched on (V CC) . In both power-on and shut-off, care should be taken that AVRH does not exceed AV CC. Even when pins which double as analog input pins are used as input ports, be sure that the input voltage does not exceed AV CC. (There is no problem if analog power supplies and digital power supplies are turned off and on at the same time.)•Handling the power supply for high-current output buffer pins (DV CC, DV SS)Always apply power to high-current output buffer pins (DV CC, DV SS) after the digital power supply (V CC) is turned on. Also when switching power off, always shut off the power supply to the high-current output buffer pins (DV CC, DV SS) before switching off the digital power supply (V CC) . (There will be no problem if high-current output buffer pins and digital power supplies are turned off and on at the same time.)Even when high-current output buffer pins are used as general purpose ports, the power for high current output buffer pins (DV CC, DV SS) should be applied to these pins.•Pull-up/pull-down resistanceThe MB90920 series does not support internal pull-up/pull-down resistance. If necessary, use external compo-nents.•Precautions for when not using a sub clock signal.If the X0A and X1A pins are not connected to an oscillator, apply pull-down treatment to the X0A pin and leave the X1A pin open.•Notes on during operation when external clock is stopped.The microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed.■BLOCK DIAGRAM■MEMORY MAPNote : To select models without the ROM mirror function, see the “ROM Mirror Function Selection Module.” The image of the ROM data in the FF bank appears at the top of the 00 bank, in order to enable efficient use of small C compiler models. The lower 16-bit address for the FF bank will be assigned to the same address, so that tables in ROM can be referenced without declaring a “far” indication with the pointer. For example when accessing the address 00C000H, the actual access is to address FFC000H in ROM. Here the FF bank ROM area exceeds 48 KB, so that it is not possible to see the entire area in the 00 bank image. Therefore because the ROM data from FF4000H to FFFFFF H will appear in the image from 004000H to 00FFFF H, it is recommended that the ROM data table be stored in the area from FF4000H to FFFFFF H.■I/O MAP•Other than CAN Interface (Continued)Address Register name Symbol Read/write Peripheral functionInitial value 00H Port 0 data register PDR0R/W Port 0X X X X X X X X 01H Port 1 data register PDR1R/W Port 1- -

常见的单片机品牌与型号介绍
常见的单片机品牌与型号介绍单片机（Microcontroller Unit，简称MCU）作为嵌入式系统的核心部件，广泛应用于各种电子设备中。
随着科技的不断发展，市场上涌现了众多单片机品牌和型号。
本文将为大家介绍常见的单片机品牌与型号，供读者参考选择。
一、Atmel（爱特梅尔）Atmel是全球领先的单片机厂商之一，其产品在市场上占据了显著的份额。
Atmel的单片机以高性能、低功耗、易用性和可靠性著称。
以下是Atmel单片机的几个典型型号：1. ATmega328P：这是一款广泛应用于Arduino开发板中的单片机，具有32KB的Flash存储器和2KB的SRAM，适合中小规模的嵌入式应用。
2. ATtiny85：这是一款微型单片机，具有8KB的Flash存储器和512字节的SRAM，尺寸小巧，适合于资源受限的应用场景。
3. ATSAM4S16C：这是一款高性能的ARM Cortex-M4核心单片机，具有256KB的Flash存储器和64KB的SRAM，适用于复杂的嵌入式系统设计。
二、STMicroelectronics（意法半导体）STMicroelectronics是全球领先的半导体解决方案供应商之一，其STMicroelectronics单片机也备受认可。
STMicroelectronics的单片机以性能稳定、丰富的外设接口以及低功耗特性而著称。
以下是几款常见的型号：1. STM32F103C8T6：这是STMicroelectronics的一款32位ARM Cortex-M3核心单片机，具有64KB的Flash存储器和20KB的SRAM，适合于中等规模的嵌入式应用。
2. STM8S003F3P6：这是STMicroelectronics的一款8位单片机，具有8KB的Flash存储器和1KB的SRAM，适合于资源受限的应用场景。
3. STM32F407VET6：这是STMicroelectronics的一款高性能32位ARM Cortex-M4核心单片机，具有512KB的Flash存储器和192KB的SRAM，适用于要求较高计算能力的嵌入式系统设计。
国内常用的单片机对比
国内常用的单片机对比1.传统51、PIC、AVR mega、STC51系列单片机对比传统51，适合菜鸟入门，容易上手，价格一般（从性价比方面说）。
IDE环境推荐keil。
缺点：解密容易（传统51说：谁让咱出道早呢，大家都研究我，哎！哭......）一般功能也有，但AD、eeprom 等功能要靠扩展,增加硬件和软件负担。
资料：/datasheet/ATMEL_PDF/AT89S52.PDFPIC：我就是学这款单片机入门的，PIC的好处就是各个型号的兼容性强，学好了PIC16f877a，16系列的就OK了，别的型号要用的时候，拿出2分钟看看数据手册就行了。
12系列16系列18系列也是充分的向下兼容。
功能全，型号多，适于选型分析，抗干扰能力强缺点：解密容易（PIC说：我出道也很早啊，人家也研究我不少年了，我和奥尼尔是英雄相惜啊！），单片机价格贵（从性价比方面说）。
IDE环境：推荐PICC+mplab。
AVR mega系列：价格便宜（从性价比方面说），硬件结构适合C语言编程，功能齐全，不容易解密。
抗干扰能力强。
型号之间兼容性一般。
应该说是比较满意的片子了。
缺点：功能寄存器多，不适合初学者----通过个人努力此缺点就不是缺点了--各位加油！推荐CVAVR+studio 其实icc、gcc也不错，大家自己斟酌，呵呵。
中文资料：/datasheet/ATMEL_PDF/ATmega16_cn.PDFstc51系列：价格最便宜（从性价比方面说），功能多，抗干扰能力最强，eeprom大，串口编程很方便（无论是对于初学者还是产品开发调试），出厂时程序引导区就已经加密，并且stc解密的市面价格在1.5w到2.5w 之间，可见解密难度大，在一定程度上保护了单片机工程师的利益和产品开发商的利益。
生产时就已经考虑到与传统51的兼容问题，兼容做的很好，又增加了许多功能，软复位功能我比较喜欢。
缺点：资料就是宏晶网上的资料，资料少，不适合初学者---我指学习它自己增加的功能。
