Frequently Asked Questions
What is the maximum clock frequency of PIC16C72A-20I/SO and what does the '20' in the part number indicate?
The '20' in PIC16C72A-20I/SO indicates a maximum clock frequency of 20 MHz. This allows the 8-bit PIC16 core to execute instructions efficiently for embedded control tasks such as sensor polling, simple communication protocols, and PWM generation in industrial or consumer applications.
Does PIC16C72A-20I/SO include an analog-to-digital converter, and how many channels does it support?
Yes, the PIC16C72A-20I/SO includes an integrated ADC, enabling analog signal acquisition directly from sensors. This eliminates the need for external ADC chips and reduces PCB area and BOM cost, making it practical for measurement, control, and monitoring applications with multiple analog inputs.
Which package does PIC16C72A-20I/SO use and how many pins are available?
The PIC16C72A-20I/SO uses a SOIC-28 package with 28 pins. The small-outline format supports surface-mount assembly on compact PCBs and provides enough I/O for typical 8-bit embedded designs including ADC inputs, digital I/O, and serial communication lines.
When would a designer choose PIC16C72A-20I/SO over a newer PIC16F-series device?
A designer maintaining legacy industrial or consumer products originally built around the PIC16C72A-20I/SO may choose it to preserve firmware compatibility and avoid re-certification. The device runs at up to 20 MHz and matches existing schematics using SOIC-28 footprints, minimizing redesign risk and board respins for established production lines.
