Key Features
- 8-bit PIC16 CPU with 3 KB OTP program memory and 72 bytes of RAM for simple embedded control tasks
- 20 available I/O pins in a 28-pin SOIC-28 package, balancing pin count with a compact SMT footprint
- XT oscillator mode supporting 4 MHz crystal operation for stable timing in cost-sensitive designs
Applications
The PIC16C57-XT/SO is designed for simple, fixed-function 8-bit control applications such as appliance timers, keypad decoders, and basic motor control where OTP Flash removes the risk of field reprogramming. Its 20 I/O pins and SOIC-28 package make it straightforward to integrate into legacy PCB designs or replace existing 28-pin MCUs in a cost-optimized manner.

Frequently Asked Questions
How much program and data memory does the PIC16C57-XT/SO offer?
The PIC16C57-XT/SO provides 3 KB of OTP program memory and 72 bytes of RAM, supporting simple 8-bit PIC16 firmware for appliance control, keypad scanning, and other fixed-function tasks that do not require frequent firmware updates.
What clock speed does the PIC16C57-XT/SO support, and what oscillator mode is available?
The PIC16C57-XT/SO operates in XT crystal oscillator mode with a maximum clock frequency of 4 MHz. This provides stable timing for sensor polling, UART communication, and timing-critical control loops in cost-sensitive 8-bit designs.
Which procurement consideration matters most when selecting the PIC16C57-XT/SO over a Flash-based PIC16 alternative?
The PIC16C57-XT/SO uses OTP memory rather than erasable Flash, so it is best suited for high-volume, fixed-firmware production runs where per-unit cost is more important than in-field reprogrammability. Buyers should note its SOIC-28 package with 20 I/O pins and plan for a factory lead time of approximately 5 weeks.
