PIC16C57T-RC/SS Equivalent & Substitute Parts

Part Overview

The PIC16C57T-RC/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 3KB OTP program memory, 72 x 8 bytes of RAM, and 20 I/O pins. Designed for embedded applications requiring external oscillator operation, this device operates at 4MHz with a supply voltage range of 3V to 6.25V and includes Power-On Reset (POR) and Watchdog Timer (WDT) peripherals.

The PIC16C57T-RC/SS carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design updates require components with improved availability or active manufacturing status.

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C57T-RC/SS is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: PIC processor family
• Core Size: 8-Bit processing capability
• Program Memory Configuration: 3KB (2K x 12) OTP memory
• RAM Capacity: 72 x 8 bytes
• I/O Pin Count: 20 pins
• Operating Voltage Range: 3V ~ 6.25V
• Speed Rating: 4MHz
• Package Type: 28-SSOP form factor
• Peripheral Set: POR and WDT functionality
• Oscillator Configuration: External oscillator requirement

The PIC16C57-RC/SS qualifies as a direct substitute based on identical electrical specifications, memory configuration, pin count, and package type. The primary distinction is product status: the substitute part maintains Active manufacturing status with verified programmability, whereas the original part is Obsolete.
