Frequently Asked Questions
What is the maximum clock frequency of the PIC16F876-20I/SO and how does it affect instruction throughput?
The PIC16F876-20I/SO operates at up to 20 MHz, executing most single-cycle instructions in 200 ns, which gives it an effective throughput of 5 MIPS for time-sensitive embedded control tasks.
How much on-chip memory does PIC16F876-20I/SO provide for firmware and runtime data?
It provides 14 KB of Flash program memory and 368 bytes of SRAM data memory, along with 256 bytes of EEPROM for non-volatile parameter storage — sufficient for moderate-complexity 8-bit firmware.
Which communication interfaces are integrated in PIC16F876-20I/SO for sensor and peripheral connectivity?
The device includes a USART for serial communication, an SPI-capable MSSP module supporting up to 4 MHz, and an I2C interface, making it suitable for connecting sensors, displays, and memory devices across 22 I/O pins.
Is PIC16F876-20I/SO a suitable drop-in replacement for PIC16F876A-20I/SO in new designs?
PIC16F876-20I/SO and PIC16F876A-20I/SO share the same SOIC-28 footprint and 22 I/O pins, but the 'A' variant adds enhanced Flash endurance. Designers should review errata before treating them as fully interchangeable at 20 MHz.
