8位 MCU微控制单元, 闪存, PIC16 Family PIC16F8XX Series Microcontrollers, 20 MHz, 14 KB, 368 Byte, 40 引脚
The PIC16F877A-I/P is a 8-bit CMOS Flash-based Microcontroller. The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 comparators, 8 channels of 10-bit Analogue-to-digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). The data EEPROM and flash program memory is readable and writable during normal operation (over the full VDD range). This memory is not directly mapped in the register file space.
