Frequently Asked Questions

What is the maximum operating clock frequency of the PIC16C622-04I/SO, and what does the '04' suffix indicate?

The PIC16C622-04I/SO operates at a maximum clock frequency of 4 MHz; the '04' in the part number denotes this 4 MHz speed grade. This makes it suitable for low-speed control tasks such as switch debouncing, LED driving, and simple sensor polling where high throughput is not required.

Does the PIC16C622-04I/SO include an analog comparator, and how does that simplify circuit design?

Yes, the device integrates an on-chip analog comparator with 2 inputs, allowing designers to perform voltage threshold detection directly without external components. This reduces BOM cost and PCB space in battery-level monitoring, motor stall detection, and over-voltage protection circuits targeting 18-pin SOIC footprints.

When would a designer choose PIC16C622-04I/SO over a higher-speed PIC16 variant for a cost-sensitive product?

For applications requiring fewer than 4 MHz of CPU throughput—such as room thermostats, simple relay controllers, or capacitive touch panels—the PIC16C622-04I/SO offers a lower-cost entry point in the PIC16 family. Its 18-pin SOIC-18 package with 128 bytes of RAM is ideal when pin count and memory footprint are naturally constrained by the application.
