Key Features
- 2K x 12-word one-time-programmable EPROM program memory sufficient for simple embedded control and sequencing tasks
- RC oscillator option enabling clock operation without external crystal, reducing BOM cost in cost-sensitive designs
- 20 I/O pins across Ports A, B, and C allowing flexible peripheral interfacing in 28-pin PDIP package
- 8-level hardware stack supporting up to 8 levels of nested subroutine or interrupt calls for structured firmware
- PIC16 architecture with 33 single-word instructions enabling fast deterministic execution at up to 4 MHz clock
Applications
The PIC16C57-RC/P is suited for simple embedded control applications such as appliance control panels, toy electronics, and low-cost consumer gadgets where an 8-bit MCU with 2K EPROM and 20 I/O pins running from a 4 MHz RC oscillator is sufficient. It is also used in educational microcontroller development boards and legacy industrial control systems that require a through-hole PDIP-28 package for hand-soldering or socketed installation. Its RC oscillator mode eliminates the crystal or resonator, lowering system cost in high-volume, non-timing-critical applications.

Frequently Asked Questions
What program memory size and architecture does the PIC16C57-RC/P provide for embedded firmware development?
The PIC16C57-RC/P has 2K x 12-word EPROM program memory and runs the PIC16 RISC architecture with 33 single-word instructions, supporting firmware loops, table lookups, and subroutine nesting up to 8 levels deep within its hardware stack.
Why might a designer choose the PIC16C57-RC/P RC oscillator variant over the XT or HS crystal versions?
The RC suffix variant uses an internal RC oscillator circuit that eliminates the need for an external crystal or resonator, reducing the component count by 2 parts and lowering BOM cost in applications such as toy controllers, appliance timers, and simple sequencers where precise clock frequency is not required and 4 MHz nominal speed suffices.
How many I/O pins does the PIC16C57-RC/P offer and how are they organized across ports?
The PIC16C57-RC/P provides 20 I/O pins organized as Port A (4 bits), Port B (8 bits), and Port C (8 bits), giving designers enough digital I/O to drive LED displays, read keypad matrices, control relays, and interface SPI or I2C peripherals in a 28-pin PDIP package.
When would the PIC16C57-RC/P be a more cost-effective alternative to a PIC16F57 for a production design?
The PIC16C57-RC/P (EPROM, one-time programmable) can be a lower-cost option than the PIC16F57 (Flash) in very high-volume production runs where firmware is finalized and never updated, since EPROM wafers may carry a lower per-unit cost at scale, and the 28-pin PDIP package allows low-cost socketed or hand-soldered assembly.
