It features 14KB Flash program memory, 368 bytes SRAM, 256 bytes EEPROM, 33 I\/O pins, 8-channel 10-bit ADC, 2 comparators, and multiple communication interfaces (USART, SPI, I2C). The 40-pin PDIP package makes it ideal for through-hole prototyping and educational lab boards. Two CCP (Capture\/Compare\/PWM) modules enable motor control and pulse generation. In-Circuit Serial Programming (ICSP) allows firmware updates without removing the device from the circuit.","working_principle":"The PIC16F877A uses Microchip's mid-range 14-bit instruction word RISC architecture. Most instructions execute in a single cycle (200ns at 20MHz). The Harvard architecture separates program and data memory buses, allowing simultaneous access. The 14KB Flash stores up to 8192 14-bit instructions. The ALU operates on data from the W register (accumulator) and file registers (SRAM-mapped SFRs and GPRs). The MSSP module implements SPI (master\/slave) and I2C (master\/slave) protocols through shift registers and baud rate generators. The 10-bit successive approximation ADC uses a capacitor DAC and comparator, converting in approximately 20us. The CCP modules combine timer resources for capture input, compare output, and PWM generation.","pin_description":"
