The device features 14 KB of Flash program memory with 100,000 write\/erase cycle endurance, 368 bytes of SRAM, and 256 bytes of data EEPROM. Running at up to 20 MHz with a 200 ns instruction cycle, it provides 5 MIPS performance. The rich peripheral set includes a 10-bit ADC with 5 input channels, an MSSP module supporting SPI and I2C master\/slave modes, a USART with 9-bit address detection, a Capture\/Compare\/PWM (CCP) module, and three timers. The SOIC-28 surface-mount package provides 22 I\/O pins, most with alternate peripheral functions. The ICSP interface supports in-circuit programming and debugging without removing the device from the board.","working_principle":"The PIC16F876A uses Microchip's 14-bit PIC core with a two-stage instruction pipeline. Most instructions execute in a single cycle (200 ns at 20 MHz), with program branches taking two cycles. The 14-bit instruction word provides direct access to all 8 KB of program memory, 368 bytes of SRAM across four banks, and all SFR registers. The 10-bit successive approximation ADC converts analog inputs through an internal sample-and-hold circuit and channel multiplexer. The MSSP module implements SPI (master\/slave with clock rates up to FOSC\/4) and I2C (master\/slave at up to 400 kHz) protocols in hardware. The USART supports asynchronous serial communication at up to 375 kBaud and synchronous communication at up to 5 MHz. The CCP module provides 16-bit capture, 16-bit compare, and 10-bit PWM functions. The 256-byte EEPROM provides non-volatile data storage accessible through SFR registers with built-in write-erase timing.","pin_description":"
