PIC16LF722A-E/MV Overview
A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash/ROM), data memory (RAM), and configurable peripherals (ADC, timers, communication interfaces) into a single chip. The PIC16LF722A belongs to the mid-range 8-bit PIC16 family within Microchip's PIC microcontroller hierarchy, optimized for low-power and battery-friendly embedded designs. Unlike more complex 32-bit Cortex-M MCUs, 8-bit PICs use a RISC-style instruction set with a 14-bit wide Flash word, giving simple deterministic timing and easy code migration.
Key features include 11-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, enhanced PWM module with up to 4 output channels, I2C/SPI/EUSART communication interfaces, internal voltage regulator (F variants only, not the LF), and a wide operating temperature range of -40C to +125C. The nanoWatt XLP feature supports multiple low-power modes (doze, idle, sleep) with peripheral-disabled current draw below 1 uA in sleep.
The 28-UQFN (4x4 mm) exposed-pad package offers compact PCB footprint and excellent thermal dissipation via the central thermal pad, which must be soldered to a copper pour. The 'E' suffix designates the -40C to +125C extended industrial temperature grade. The 'MV' suffix specifies the UQFN-28 (4x4) package.
Typical applications include battery-powered sensor nodes, remote controls, consumer electronics white goods, low-cost IoT edge nodes, and human-interface devices. The wide supply range and ultra-low sleep current make it especially suited for energy-harvesting and coin-cell-powered designs where the MCU spends most of its time dormant.
For stable operation, place 0.1 uF decoupling capacitors close to VDD pins and connect the exposed pad (EP) to a ground copper pour for both thermal and electrical reference. Internal WDT and POR reduce external component count on cost-sensitive designs.

Typical Applications
PIC16LF722A-E/MV is suitable for 6 applications: Battery-Powered Sensor Node, Remote Control / IR Transmitter, Home Appliance Control Board, IoT Edge / Simple Connected Sensor, Hobby / Maker Education Project, Energy Harvesting Switch / Wireless Pushbutton.
Battery-Powered Sensor Node
The PIC16LF722A-E/MV fits battery-powered sensor nodes thanks to its nanoWatt XLP technology and ~20 nA typical sleep current, which together enable multi-year lifetimes on a single CR2032 coin cell. Its 2.3V-3.6V operating range matches two-alkaline or single LiCoin cell chemistries without regulation. The 11-channel 8-bit ADC samples low-frequency sensor signals (temperature, light, motion) while the 28-UQFN-EP package keeps the board smaller than 10x10 mm, important for wearables. Compared to 32-bit Cortex-M competitors, this PIC16 costs roughly a third and draws an order of magnitude less quiescent current.
Recommended
Remote Control / IR Transmitter
For infrared remote controls, the PIC16LF722A-E/MV delivers just enough compute power for IR protocol encoding (RC5, NEC, Sony SIRC) and provides a PWM module accurate enough to generate 38 kHz carrier frequencies with minimal CPU overhead. With 3.5 KB Flash, simple protocol stacks fit comfortably. The 4-channel PWM can modulate multiple IR LEDs or drive a buzzer for keystroke feedback. The wide -40C to +125C operating temperature keeps remote control units reliable in cold weather and high-heat shipping containers alike.
Recommended
Home Appliance Control Board
In white-goods appliances like washing machines, dishwashers, and microwave oven control panels, the PIC16LF722A-E/MV drives user-interface tasks: key matrix scanning, 7-segment or LCD display driving, and relay/buzzer control. Its nanoWatt XLP and extended -40C to +125C temperature range handle both standby current and kitchen-heat stress. The 28-UQFN package plus small footprint lets designers save PCB area for power triacs. Compared with discrete 555 timers used for simple timing tasks, this MCU offers upgrade paths for adding IoT features later.
Recommended
IoT Edge / Simple Connected Sensor
For battery-powered IoT edge devices (BLE beacons, LoRa wake-up controllers, garage-door tilt sensors), the PIC16LF722A-E/MV serves as the low-cost host MCU that wakes periodically, samples sensors, and forwards data via UART/SPI to a connectivity chip. Its internal oscillator (16 MHz) and EUSART/SPI peripherals connect directly to transceiver modules without external crystals. Sleep currents below 1 uA extend coin-cell life over multiple years. Note: this MCU does not include native wireless radio; pair it with a discrete modem for full IoT connectivity.
Recommended
Hobby / Maker Education Project
Hobbyists and education programs use the PIC16LF722A-E/MV (or its 6x6 mm QFN sister PIC16LF722A-E/ML) for Arduino-like blinking-LED lessons, motor-controller labs, and sensor-data experiments on platforms like Curiosity or MPLAB Xpress boards. Its 28 pins expose enough I/O for driving 4 motors, character LCDs, and a few buttons simultaneously. With Microchip's free MPLAB X IDE + XC8 compiler, students build inexpensively reusable firmware across PIC families. The PIC16LF722A-E/ML sibling variant in larger QFN-28 (6x6 mm) is friendlier to breadboard-adapter soldering than the 4x4 UQFN.
Recommended
Energy Harvesting Switch / Wireless Pushbutton
Self-powered wireless switches (EnOcean-style, kinetic-impulse energy harvesting) benefit from the PIC16LF722A-E/MV's XLP sleep current of ~20 nA and ability to wake up, perform a serial transmission, and return to sleep within a few milliseconds. The 2.3V-3.6V supply range matches the capacitor-stored voltage from a small energy harvester. Combined with a low-energy RF transmitter (e.g. RFM75 or similar), this PIC16LF enough memory and I/O to encode unique IDs and drive multiple pulse transmissions. Engineers must budget for average current <10 uA for battery-free operation.

Key Differentiators
- Only 28-UQFN PIC16LF family member with extended -40 to +125C and lowest BOM cost (vs PIC16LF722A-I/MV)
- Lowest-voltage variant without external LDO stabilization cap requirement (vs PIC16F722A-E/MV)
- Compact 4x4 mm UQFN footprint saves PCB area (vs PIC16LF722A-E/ML)
Design Notes
The PIC16LF722A-E/MV's 28-UQFN-EP package has a central exposed pad that MUST be soldered to a board-level ground copper pour (recommended at least 10 mm^2) for both electrical reference and thermal dissipation. Without proper EP soldering, junction-to-ambient thermal resistance rises and self-heating may affect ADC readings in enclosed housings. Also place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a 10 uF bulk capacitor within 10 mm for stable mid-power transients.
For nanoWatt XLP designs, disable all peripherals in the OSCCON and enable register mask before entering Sleep, and configure the WDT postscaler for >=1 second timeout if you need a watchdog wake. The LF variant does not require a VCAP cap (unlike the F variant), but adding a 100 nF cap on VDD within 5 mm remains recommended to suppress inductive kickback during RF transmissions or motor switching. Average current <10 uA achievable with 99.9% duty cycle sleep and periodic sensor reads.
The PIC16LF722A lacks the internal voltage regulator found on PIC16F722A, so do NOT apply >3.6 V directly to VDD or you risk permanent damage. If your design must accept a 5 V rail, choose the PIC16F722A-E/MV alternative. Also note that the UQFN-28 (4x4) lacks hand-solder-friendly leads and requires reflow or hot-plate assembly; for breadboard-friendly prototyping, use the sister part PIC16LF722A-E/ML in larger QFN-28 (6x6 mm) on a Microchip Curiosity or DM164141 board.
