Applications
The PIC16C57-10/SO is designed for high-volume, cost-driven applications such as home appliance control panels, simple keyboard scanners, and toy electronics where a small fixed program is burned once into OTP memory at manufacture. Its 20 I/O pins and 10 MHz clock make it effective for driving LED display multiplexing and basic sensor input processing. The SOIC-28 package enables straightforward PCB assembly in consumer and industrial products that do not require field-programmable firmware updates.

Frequently Asked Questions
How much program memory and RAM does the PIC16C57-10/SO provide for embedded firmware?
The PIC16C57-10/SO includes 2KB of one-time programmable OTP program memory and 72 bytes of general-purpose data RAM. This capacity is sufficient for straightforward control loops, LED scanning routines, and simple state machines running at 10 MHz with the 33-instruction PIC16 RISC architecture.
What distinguishes OTP program memory in PIC16C57-10/SO from Flash-based PIC microcontrollers?
OTP memory is written exactly once and cannot be erased or reprogrammed, which reduces die cost and is ideal for mature, stable firmware in high-volume consumer goods manufactured in batches of tens of thousands. Unlike Flash-based PIC16F devices that support multiple reprogram cycles, the PIC16C57-10/SO is not suited for designs requiring field firmware updates.
How many I/O pins does the PIC16C57-10/SO expose, and what peripherals can they drive?
The SOIC-28 package exposes 20 general-purpose digital I/O pins organized across ports A, B, and C. These pins can directly sink or source current to drive LEDs, interface 4×4 keypad matrices, and communicate with external shift registers or basic sensors without requiring additional driver ICs.
Is PIC16C57-10/SO compatible with 5 V logic systems used in legacy industrial control boards?
Yes, the PIC16C57-10/SO operates on a 2.5 V to 5.5 V supply rail and is fully compatible with 5 V TTL and CMOS logic levels common in legacy industrial control boards, PLCs, and retrofit appliance designs, simplifying integration without level-shifting hardware in the -40°C to +85°C commercial temperature range.
