Frequently Asked Questions

What clock frequency does PIC16C620A-04/SO support, and how does that affect timing-sensitive designs?

PIC16C620A-04/SO operates at a maximum clock frequency of 4 MHz, yielding an instruction cycle of 1 µs. This is adequate for simple control loops, debounce routines, and low-speed serial communication in cost-sensitive embedded systems.

Which supply voltage range is compatible with PIC16C620A-04/SO for battery-powered applications?

The device operates from 2.5 V to 6.0 V, making it suitable for single-cell lithium, two-cell alkaline, or regulated 3.3 V and 5 V rails. This wide range simplifies power-supply design in portable or battery-backed products.

How does the 18-pin SOIC package of PIC16C620A-04/SO impact board layout compared to DIP alternatives?

The SOIC-18 package occupies a body footprint of approximately 11.6 mm × 7.5 mm with 18 pins on 1.27 mm SMT pitch, considerably smaller than an 18-pin DIP. This lets designers reduce PCB area on automated assembly lines.

Is PIC16C620A-04/SO RoHS-compliant, and what lifecycle status should procurement teams plan for?

Microchip lists the part as Pb-free and RoHS-compliant. Being an older OTP device introduced around 1990, procurement teams should review last-time-buy stock and evaluate pin-compatible Flash replacements such as PIC16F628A to manage lifecycle risk over a 5-year horizon.
