What are the key features of PIC16LF722-I/SO?
- Operates from as low as 1.8 V supply at 16 MHz, enabling direct integration in battery-powered and energy-harvesting designs
- 25 I/O pins with integrated ADC channels in a SOIC-28 package for versatile peripheral connectivity without external components
- 3.5 KB Flash and 128 bytes RAM support a wide range of embedded control firmware with room for application code
- PIC16 CPU family compatibility allows firmware reuse across the broad Microchip 8-bit ecosystem with a single toolchain
What is PIC16LF722-I/SO used for?
The PIC16LF722-I/SO is suited for low-power embedded control applications such as battery-operated sensors, home automation nodes, and industrial I/O expanders that require multiple analog inputs and digital I/O on a single chip. Its 1.8 V minimum supply makes it a natural fit for designs powered by two AA cells or small lithium-ion batteries where regulated 3.3 V is unavailable. The SOIC-28 package allows hand-soldering during prototyping and straightforward SMT assembly in volume production.

Frequently Asked Questions
How low a supply voltage can the PIC16LF722-I/SO operate from and at what clock frequency?
The PIC16LF722-I/SO can operate from a minimum supply voltage of 1.8 V while running at 16 MHz, and up to 20 MHz at higher supply voltages. This 1.8 V capability makes the device suitable for systems powered directly by two-cell alkaline battery packs, small LiPo cells, or energy-harvesting regulators where the rail may drop below 2 V during discharge.
How many I/O pins and ADC channels does the PIC16LF722-I/SO provide for sensor interface designs?
The PIC16LF722-I/SO provides 25 I/O pins and an integrated ADC, allowing direct connection of multiple analog sensors such as temperature, pressure, or light sensors without external ADC chips. The SOIC-28 package accommodates all 25 I/O pins on a standard 28-lead outline, keeping the BOM compact for sensor hub designs measuring several physical parameters simultaneously at sample rates up to the ADC's conversion speed.
Is the PIC16LF722-I/SO compatible with existing PIC16F722 firmware without modification?
The PIC16LF722 is the low-voltage variant of the PIC16F722 and is largely pin- and code-compatible. Both share the same 8-bit PIC16 core with 3.5 KB Flash and 128 bytes RAM running up to 20 MHz. The primary difference is that the LF variant supports operation down to 1.8 V, whereas the standard F722 requires a higher minimum supply. Existing MPLAB firmware compiled for the PIC16F722 can generally target the PIC16LF722 after selecting the correct device in the project settings.
For a compact industrial sensor node, what advantages does the SOIC-28 package offer over a DIP-28 package?
The SOIC-28 package for the PIC16LF722-I/SO measures approximately 17.9 mm × 7.5 mm, less than half the board area of an equivalent DIP-28 at 35.6 mm × 13.3 mm. The surface-mount footprint eliminates through-hole drilling, reduces PCB layer routing complexity, and enables placement on both sides of a board. For industrial IoT sensor nodes targeting compact enclosures of 50 mm × 50 mm or smaller, the SOIC-28 is the preferred form factor.
