Frequently Asked Questions

What clock frequency and CPU architecture does PIC16C74B-20/L use?

The PIC16C74B-20/L uses an 8-bit PIC16 RISC architecture operating at up to 20 MHz. At this frequency the device executes most single-cycle instructions in 200 ns, making it suitable for real-time control tasks in industrial automation and consumer appliance applications.

Which sensor interface applications take advantage of the PIC16C74B-20/L's on-chip ADC?

Temperature monitoring, pressure sensing, and light-level measurement applications all benefit from the PIC16C74B-20/L's built-in ADC, eliminating the need for external analog-to-digital conversion chips. This integration reduces BOM cost and PCB complexity in data-logger and process-control designs operating from a 5 V supply rail.

How does PIC16C74B-20/L fit into a legacy embedded control design using a PLCC socket?

The PIC16C74B-20/L in a 44-pin PLCC package can be installed directly in standard PLCC-44 through-hole sockets, simplifying field replacement and prototype iteration. This makes it a practical choice for industrial equipment designs from the 1990s era still in maintenance, where replacing an 8-bit 20 MHz controller without board redesign is necessary.
