Frequently Asked Questions
What is the maximum clock frequency and program memory size of PIC16F72-I/SO?
The PIC16F72-I/SO operates at up to 20 MHz and provides 3.5KB of Flash program memory, giving it sufficient throughput for most 8-bit embedded control tasks while keeping cost and power consumption low.
How low can the supply voltage go on PIC16F72-I/SO, and does that affect the ADC?
PIC16F72-I/SO can operate at a minimum of 2V supply voltage; however, the 8-channel 8-bit ADC requires a higher voltage to function correctly. At 2V minimum the ADC is disabled, making the device suitable for low-voltage digital-only applications.
Which serial communication interfaces does PIC16F72-I/SO support for sensor integration?
PIC16F72-I/SO supports USART, SPI, and I2C serial interfaces across its 22 I/O pins in the 28-pin SOIC package, allowing direct connection to temperature sensors, EEPROMs, displays, and other peripherals without external glue logic.
When would PIC16F72-I/SO be preferred over a larger PIC16F887 for a cost-sensitive design?
For designs needing only 8-bit ADC resolution, up to 22 I/O pins, and 3.5KB Flash at 20 MHz, PIC16F72-I/SO is a lower-cost alternative to PIC16F887, which adds 256-byte EEPROM and 14-channel 10-bit ADC at higher price and larger package footprint.
