PIC16F877A Microcontroller

The PIC16F877A is a 28/40/44-Pin Enhanced Flash Microcontrollers . The following are the features:-

• Timer0: 8-bit timer/counter with 8-bit prescaler

• Timer1: 16-bit timer/counter with prescaler, can be incremented during Sleep via external crystal/clock

• Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler

• Two Capture, Compare, PWM modules

– Capture is 16-bit, max. resolution is 12.5 ns

– Compare is 16-bit, max. resolution is 200 ns

– PWM max. resolution is 10-bit

• Synchronous Serial Port (SSP) with SPI (Master mode) and I2C™ (Master/Slave)

Universal Synchronous Asynchronous Receiver Transmitter (USART/SCI) with 9-bit address detection

• Parallel Slave Port (PSP) – 8 bits wide with external RD, WR and CS controls (40/44-pin only)

• Brown-out detection circuitry for Brown-out Reset (BOR)
