What are the key features of PIC16C56-XT/P?
- 8-bit PIC16 RISC core with 33 single-word instructions enables low-overhead firmware development for cost-sensitive applications
- One-time programmable (OTP) 1.5KB program memory in compact PDIP-18 package ideal for high-volume production with fixed code
- 12 bidirectional I/O pins operating at 4 MHz crystal clock with low standby current for battery-powered simple control tasks
What is PIC16C56-XT/P used for?
The PIC16C56-XT/P is suited for low-complexity consumer appliance controllers, toy motor drives, and simple timer-relay circuits where OTP program memory and a low pin count reduce overall BOM cost. Its PDIP-18 through-hole package simplifies manual assembly and prototyping in low-volume industrial control modules. The 4 MHz crystal operation and 12 I/O pins cover most basic sequential logic replacement use cases.

Frequently Asked Questions
What program memory capacity and RAM does the PIC16C56-XT/P provide for firmware?
The PIC16C56-XT/P has 1.5KB (1,536 words) of OTP program memory and 25 bytes of SRAM data memory. While modest by modern standards, this is sufficient for simple state machine and sequential control applications running at 4 MHz.
How does the OTP program memory affect production programming strategy compared to Flash-based PIC devices?
Because PIC16C56-XT/P uses one-time programmable memory, devices cannot be erased and reprogrammed after initial programming. Production runs must be fully verified in simulation first; for code that may evolve, a Flash-based alternative like PIC16F56 with 2KB Flash is preferable.
Which low-complexity embedded designs benefit most from the PDIP-18 through-hole package?
Through-hole PDIP-18 packages suit prototype boards, educational kits, and repair-grade industrial controllers where soldering skill is basic. The 18-pin DIP footprint fits standard 0.3-inch IC sockets, making in-field replacement straightforward without SMD rework tools.
What is the maximum clock frequency and how does it affect instruction throughput for PIC16C56-XT/P?
The PIC16C56-XT/P supports up to 4 MHz external crystal frequency. With a 4-clock instruction cycle, this delivers 1 MIPS throughput, which is adequate for sub-millisecond loop timing in appliance timing circuits or relay sequencer control logic.
