Frequently Asked Questions
What is the maximum clock frequency supported by the PIC16C622A-04I/SO?
The PIC16C622A-04I/SO supports a maximum clock frequency of 4 MHz. This 8-bit PIC16-family microcontroller is designed for low-speed embedded tasks where a 4 MHz clock provides sufficient throughput for sensor reading, timer control, and simple digital I/O operations without requiring a high-speed oscillator.
How does the on-chip analog comparator in PIC16C622A-04I/SO benefit sensor interface designs?
The PIC16C622A-04I/SO integrates on-chip analog comparators that allow direct comparison of analog sensor signals against a reference voltage without external op-amps, reducing BOM cost and PCB area. This makes it suitable for threshold-detection applications such as battery monitoring, temperature cutoffs at specific voltage levels, and level-sensing with a 5 V supply rail.
Is the PIC16C622A-04I/SO appropriate for designs needing reprogrammable firmware in small production runs?
Yes. The PIC16C622A-04I/SO uses EPROM-based program memory, which can be erased with UV light and reprogrammed, making it suitable for prototyping and small-volume production runs of up to a few hundred units. Its 8-bit architecture with 128 bytes of RAM and 4 MHz operation covers most simple embedded control tasks efficiently.
What PCB footprint does the SOIC-18 package of PIC16C622A-04I/SO require?
The PIC16C622A-04I/SO comes in a standard SOIC-18 package with 18 pins on a 1.27 mm pitch and a body width of approximately 7.5 mm, requiring a board footprint of roughly 11.6 mm x 7.5 mm. This compact SMT outline makes it easy to integrate into space-constrained PCB layouts using standard reflow soldering processes.
