PIC16F877-20/P Datasheet PDF - Microchip

●The PIC16F877-20/P is a 8-bit 20MHz CMOS Flash-based Microcontroller. The PIC16F876 features 256 bytes of EEPROM data memory, self programming, an ICD, 5 channels of 10-bit Analogue-to-digital (A/D) converter, 2 additional timers, 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 STATUS register contains the arithmetic status of the ALU, the RESET status and the bank select bits for data memory.
