Substitute Part Grouping Explanation

Substitution for the PIC16C56T-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: 1.5KB OTP capacity
• RAM Configuration: 25 x 8 byte organization
• I/O Count: 12 I/O pins
• Operating Voltage: 3V to 6.25V supply range
• Speed Rating: 4MHz operation
• Package Type: 20-SSOP surface mount form factor
• Peripheral Set: POR (Power-On Reset) and WDT (Watchdog Timer)

The PIC16C56-RC/SS qualifies as a direct substitute based on identical electrical specifications, memory configuration, I/O architecture, and package format. Both parts share the same base product number (PIC16C56) and are functionally equivalent at the component level.

Parameter Comparison
