Frequently Asked Questions
How much program memory and RAM does the PIC16C56A-04/SS provide, and is it reprogrammable?
The PIC16C56A-04/SS provides 1.5 KB of OTP (one-time programmable) program memory and 25 bytes of RAM. OTP means the device is programmed once during production and cannot be erased or reprogrammed, making it cost-effective for finalized, high-volume firmware but unsuitable for field-updatable applications.
What is the maximum clock frequency of PIC16C56A-04/SS, and how does this affect throughput?
The PIC16C56A-04/SS operates at a maximum clock frequency of 4 MHz, executing most instructions in a single 250 ns instruction cycle (one instruction per 4 clock cycles). This throughput is sufficient for simple control loops, switch debouncing, and sequential output driving tasks common in appliance and timer circuits.
How does PIC16C56A-04/SS compare to later PIC16F devices for a new design?
For new designs, PIC16F devices such as PIC16F630 offer flash reprogrammability, more RAM, and additional peripherals like ADC and timers at similar or lower cost compared to the OTP PIC16C56A-04/SS. However, existing legacy boards using the 20-pin SSOP footprint with 4 MHz timing may continue sourcing PIC16C56A-04/SS to avoid re-qualification, despite 111-week lead times.
