Frequently Asked Questions
How much program memory and data RAM does the PIC16C56A-04/SO provide?
The PIC16C56A-04/SO provides 1024 words of OTP program memory and 25 bytes of on-chip data RAM. These resources are appropriate for simple embedded control routines such as sequential switching, timer-based tasks, and basic sensor reading at up to 4 MHz clock frequency on the 8-bit PIC16 core.
What I/O pin count is available on the PIC16C56A-04/SO and what applications does it fit?
The PIC16C56A-04/SO in SOIC-18 package provides up to 12 I/O pins, sufficient for driving relays, reading digital switches, and controlling indicator LEDs in compact consumer appliances. The 8-bit PIC16 architecture at 4 MHz handles simple sequential control logic without requiring a higher-performance or more expensive microcontroller platform.
Is the PIC16C56A-04/SO suitable as a legacy replacement in designs originally built around early PIC16 devices?
Yes, the PIC16C56A-04/SO is architecturally compatible with early PIC16 family devices, sharing the same 8-bit RISC core, 4 MHz maximum clock, and SOIC-18 pin-out conventions. Designers maintaining legacy boards can drop in the PIC16C56A-04/SO without layout changes, preserving 12 I/O pins and 1024 words of OTP program memory in a direct package-compatible footprint.
