Product Overview
Microchip PIC16F873A-I/SP 8-bit microcontroller in a 28-pin skinny dual in-line package (SPDIP). Based on the PIC RISC architecture, this MCU provides 7 KB of Flash program memory, 192 bytes of SRAM, and 128 bytes of EEPROM. It is designed for through-hole assembly in industrial control systems, instrumentation, legacy device maintenance, and embedded prototyping.
Key Features
- 8-bit RISC core operating up to 20 MHz
- 7 KB Flash program memory (4K x 14 words)
- 192 bytes SRAM and 128 bytes onboard EEPROM data storage
- 5-channel 10-bit Analog-to-Digital Converter (ADC)
- Serial communication support for USART, SPI, and I2C
- Three internal timers: Timer0 (8-bit), Timer1 (16-bit), and Timer2 (8-bit)
- 22 general-purpose input/output lines
- 2.0V to 5.5V operating voltage range
- Standard 28-pin SPDIP through-hole footprint
Applications
- Replacing damaged microcontrollers in legacy industrial controllers, machine interfaces, and production gear.
- Programming dedicated firmware for hobbyist electronics, robotics projects, and breadboard circuit development.
- Repairing legacy electronic instruments without redesigning the printed circuit board for modern surface-mount components.
Frequently Asked Questions
What package style does this microcontroller use?
It is a 28-pin Skinny DIP (SPDIP-28) through-hole package, fitting standard 0.300-inch wide DIP sockets and breadboards.
Does this chip come pre-programmed?
No. This is a blank microcontroller ready to be programmed with your application code using a compatible in-circuit or socket programmer.
Why buy a single PIC16F873A-I/SP here instead of hunting down a bulk surplus lot?
Buying individually lets you secure the exact replacement component required for a repair or build without paying for surplus volume that goes unused. You receive the specific, photographed Microchip IC ready for your bench. Shipping is $8 flat rate, free once the order passes $28, and orders leave the Idaho warehouse the same or next business day.
Nothing beats the simplicity of socketing a clean through-hole microcontroller and watching a legacy board wake right back up. Plug it in, burn your code, and let the hardware do the rest.
