Product Overview
The Microchip PIC16F876-20/SP is an 8-bit RISC microcontroller housed in a compact 28-lead Skinny Plastic Dual In-Line Package (SPDIP). Operating at clock speeds up to 20 MHz, this classic architecture integrates 14 KB of Flash program memory, 368 bytes of RAM, and 256 bytes of data EEPROM. The onboard peripheral set includes a 5-channel 10-bit analog-to-digital converter, two capture/compare/PWM modules, and hardware synchronous and asynchronous serial ports (USART, SPI, and I2C), making it a reliable drop-in solution for industrial automation repairs, instrumentation benches, and legacy embedded systems maintenance.
Key Features

- 368 bytes of data SRAM and 256 bytes of non-volatile data EEPROM
- 22 programmable I/O lines
- 5-channel, 10-bit analog-to-digital converter (ADC) module
- Dual 8-bit timers and one 16-bit timer
- Two capture/compare/PWM (CCP) peripheral modules
- Serial communications support including addressable USART, SPI, and I2C master/slave modes
- Operating voltage range of 4.0 V to 5.5 V at 20 MHz
- Commercial operating temperature rating of 0°C to +70°C
Applications
- Restoring or repairing legacy industrial controllers and machine tools that depend on 28-pin PIC16F-series firmware.
- Benchtop development and testing of embedded firmware on breadboards or through-hole prototyping boards.
- Replacing damaged DIP microcontrollers in vintage automation gear, laboratory instruments, and custom robotics.
- Hobbyist and maker projects requiring dedicated hardware PWM, A/D sampling, or legacy I2C/SPI sensor interfaces.
Frequently Asked Questions
What is the difference between the standard DIP and the SPDIP package?
The PIC16F876-20/SP uses an SPDIP (Skinny Plastic Dual In-Line Package), which has a narrow 0.300-inch (7.62 mm) row spacing between pins, rather than the wider 0.600-inch spacing found on standard 28-pin DIP devices. It fits narrow 28-pin IC sockets and standard solderless breadboards.
What operating voltage does this microcontroller require?
For operation at the full 20 MHz rating, the PIC16F876-20/SP requires a supply voltage between 4.0 V and 5.5 V DC.
Why buy individual PIC16F876 chips here instead of surplus reels?
Ordering an exact count saves you from buying excess inventory or unverified multi-chip lots when you only need one or two clean replacement ICs for a repair. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free once the order passes $28, and leave our Idaho warehouse the same or next business day.
