Frequently Asked Questions
How many ADC channels and what resolution does the PIC16C72-20I/SO integrate?
The PIC16C72-20I/SO includes an 8-channel, 8-bit successive approximation ADC, enabling simultaneous monitoring of up to 8 analog signals such as temperature sensors or potentiometers at a 20 MHz system clock without any external ADC hardware.
What supply voltage range does the PIC16C72-20I/SO support, and is it suitable for battery-powered designs?
The device operates from 2.5 V to 5.5 V, making it compatible with single-cell 3 V lithium coin cells, two AA alkaline cells (approximately 3 V), and standard 5 V regulated supplies, giving designers flexibility across a wide range of battery and mains-powered applications.
Which package does the PIC16C72-20I/SO use, and how many I/O pins are available?
It comes in a 28-pin SOIC package with a 0.3-inch body width and provides 22 programmable digital I/O pins, a practical pin count for controlling relays, driving LEDs, and reading switches in compact embedded boards.
When would a designer choose PIC16C72-20I/SO over a PIC16F device for a legacy design?
The PIC16C72 uses OTP (one-time programmable) ROM rather than Flash, so it suits high-volume production runs where firmware is finalized and the lower cost of OTP memory outweighs the reprogramming flexibility of PIC16F Flash parts at 20 MHz performance.
