Frequently Asked Questions
What clock speed does the PIC16C558-20/P support and how does it affect instruction throughput?
The PIC16C558-20/P supports a maximum clock frequency of 20 MHz, delivering up to 5 MIPS throughput on its single-cycle RISC instruction set. This speed is sufficient for real-time control loops in embedded systems running at 3.3 V or 5 V supply rails.
How much on-chip memory does the PIC16C558-20/P provide for program and data storage?
It provides 2 KB of OTP program memory and 73 bytes of on-chip SRAM data memory. These resources are ample for compact firmware routines used in sensor interfacing, PWM generation, or simple communication protocols running on 8-bit PIC16 architecture.
Which supply voltage range does the PIC16C558-20/P accept, and is it suitable for 3.3 V battery-powered designs?
The PIC16C558-20/P operates across a supply voltage range of 2.5 V to 6.0 V, making it compatible with 3.3 V lithium-cell and 5 V regulated designs. It also functions at 4 MHz with a minimum 3.0 V supply, offering flexible power budgets for battery-powered embedded applications.
When would a designer choose PIC16C558-20/P over a flash-based PIC16 for a production run?
A designer would choose the PIC16C558-20/P OTP device when production firmware is finalized and code security is a priority, since OTP memory cannot be reprogrammed after programming. Cost per unit in volume is typically lower than flash equivalents, and the 18-pin PDIP package fits existing through-hole tooling without PCB redesign for runs exceeding 10,000 units.
