Product details

8-bit PIC MCU with 16 MHz core and wide voltage range

The Microchip PIC16F720-I/SO is an 8-bit PIC® 16F series microcontroller built around a 16 MHz core, delivering a 64 ns instruction cycle for control-loop and serial-protocol tasks.

Peripheral set for sensor and serial applications

A 12-channel 8-bit ADC handles basic analog measurements — battery voltage, potentiometer position, or thermistor readout — without an external converter. The peripheral complement also includes Brown-out Detect/Reset, POR, PWM, and WDT, which together provide supervised operation and pulse-width modulation for dimming LEDs or driving small motors.

Microchip lists the PIC16F720-I/SO as Active (current production) with ROHS3 compliance. The base product number PIC16F720 covers multiple package and temperature variants, giving some flexibility if the 20-SOIC form factor ever needs a substitute within the same die family.

Frequently asked questions

Does PIC16F720-I/SO have SPI and I2C?

Yes, the PIC16F720-I/SO includes both I²C and SPI connectivity, along with a UART/USART interface. These three serial buses are available on the 17 I/O pins, so you can connect to common peripherals like EEPROMs, sensors, or wireless modules without bit-banging.

What is the difference between PIC16F720 and PIC16F722?

The PIC16F722 is a close sibling in the same baseline family, but it steps up to 28 pins (vs 20 on the PIC16F720) and offers 7 KB Flash program memory versus 3.5 KB. Both share the same 16 MHz core, 1.8 V–5.5 V supply range, and industrial temperature grade. The choice comes down to pin count and memory headroom — the PIC16F720 fits a 20-pin SOIC footprint, while the PIC16F722 requires a 28-pin package.
