PIC16F722-E/ML Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), peripherals, and I/O on one die, executing instructions 8 bits at a time. Within Microchip's taxonomy, the PIC16F722 belongs to the mid-range PIC16 family -> 8-bit PIC microcontroller -> microcontroller -> embedded processor -> semiconductor. Mid-range PIC16 parts use a RISC Harvard architecture with 35 single-word instructions and 200 ns instruction execution at 20 MHz, balancing code density, deterministic interrupt response, and ease of development with MPLAB X and XC8.
Key features of the PIC16F722-E/ML include 3.5 KB self-programmable Flash, 128 B RAM, up to 36 digital I/O pins (28-pin variant shares most peripherals), 11 channels of 8-bit ADC, two 8-bit timers plus one 16-bit timer, Enhanced CCP, USART, MSSP (I2C/SPI), 2x comparators, internal 16 MHz oscillator, and the nanoWatt XLP sleep current typically below 50 nA. The UQFN-28 (ML) package is a 5 x 5 mm body with 0.5 mm pitch and an exposed thermal pad for PCB heatsinking.
Typical applications include low-power sensor nodes, mTouch capacitive touch interfaces, battery chargers, LED drivers, simple motor control, and consumer white goods. The 28-pin UQFN package suits space-constrained surface-mount assemblies where a small footprint and good thermal performance are required simultaneously.
When designing, place decoupling capacitors as close as possible to VDD/VSS pairs and connect the exposed thermal pad to a continuous ground plane for thermal and electrical performance. Verify MPLAB X device support and pick the appropriate PIC16F722 header file before code generation.

Typical Applications
PIC16F722-E/ML is suitable for 6 applications: Battery-Powered Sensor Node, mTouch Capacitive Touch Interface, LED Lighting Controller, Consumer White Goods Control, Simple Brushless DC Motor Control, Industrial Sensor Transmitter.
Battery-Powered Sensor Node
The PIC16F722-E/ML is well suited for battery-powered sensor nodes because it integrates nanoWatt XLP extreme-low-power technology, achieving typical sleep currents below 50 nA. With its 20 MHz 8-bit core, 3.5 KB Flash for sensor-firmware logic, and 11-channel 8-bit ADC for analog sensor read-out, it can wake on timer, sample a sensor, transmit via EUSART/MSSP, and return to sleep. A typical CR2032-powered node with 1% duty cycle can run for years. The 28-pin UQFN package provides a compact 5 x 5 mm footprint ideal for wearable and IoT sensor pcb designs.
Recommended
mTouch Capacitive Touch Interface
The PIC16F722-E/ML is supported by Microchip's mTouch capacitive-touch firmware library, providing up to 11 touch channels via the 8-bit ADC and CTMU charge-time measurement unit. With 3.5 KB Flash and 128 B RAM, it can drive 8-12 capacitive buttons or a small slider/touch wheel with debounce and gesture handling. The 28-pin UQFN package fits behind glass or thin overlays. Pair with the MCP6S26 programmable gain amp for proximity-sensing extensions in white-goods and consumer-electronics front panels.
Recommended
LED Lighting Controller
The PIC16F722-E/ML is well matched for LED lighting controllers because its Enhanced CCP module generates PWM at frequencies up to 20 kHz - above the audible band - for flicker-free dimming of constant-current LED strings. With EUSART and MSSP, the part interfaces to DMX-512, 0-10 V, or wireless modules for smart-lighting networks. The 28-pin UQFN (5 x 5 mm) and 2.0V-5.5V operation support compact driver boards running directly from a rectified mains supply with small buck conversion.
Recommended
Consumer White Goods Control
The PIC16F722-E/ML fits consumer white-goods main-control boards because its extended -40C to +125C temperature range handles under-cabinet or motor-driver heat. The 11-channel 8-bit ADC reads temperature sensors, water level, and potentiometers; the EUSART interfaces to a UI display or Wi-Fi module; and the 3.5 KB Flash holds the appliance control firmware. The UQFN-28 small footprint is ideal for densely populated main-control boards, and nanoWatt XLP helps meet standby power regulations like ErP Lot 6.
Recommended
Simple Brushless DC Motor Control
The PIC16F722-E/ML can drive simple BLDC or brushed-DC motors using its Enhanced CCP PWM, 16-bit timer, and on-chip comparators for back-EMF sensing or current-limit feedback. With 20 MHz core and 8-bit ADC, it supports basic trapezoidal commutation for low-cost fans, pumps, or small appliances. The 28-pin UQFN is small enough for in-motor driver boards. Pair with the MCP1416 gate driver for direct low-side drive of small MOSFET bridges.
Recommended
Industrial Sensor Transmitter
The PIC16F722-E/ML's extended temperature grade (-40C to +125C) and 2.0V-5.5V operation make it ideal for industrial 4-20 mA sensor transmitters and 0-10 V process-control output modules. The 8-bit ADC (11 channels) handles multiple sensor inputs, EUSART interfaces to a host PLC or wireless module, and nanoWatt XLP keeps loop-powered designs within budget. The UQFN-28 (5 x 5 mm) and exposed thermal pad enable compact DIN-rail-mount transmitter PCBs that dissipate heat efficiently.

Key Differentiators
- Smallest-footprint nanoWatt XLP MCU in 28-pin mid-range family (vs PIC16F722-I/SP (DIP-28))
- Silicon-revision drop-in upgrade path (vs PIC16F722A-E/ML)
- Memory scalability within the same UQFN-28 footprint (vs PIC16F723-E/ML / PIC16F727-E/ML)
Design Notes
Place a 0.1 uF decoupling capacitor as close as possible to each VDD pin (pins 19 and 28 on UQFN-28) with a short, wide trace to VSS. Add a bulk 1-10 uF tantalum or ceramic on the same rail near the IC. The exposed thermal pad (EP) of the UQFN-28 MUST be soldered to a continuous ground plane for both thermal dissipation and electrical performance - skipping this step is a common cause of erratic brown-out resets and erratic ADC readings.
The "-E" suffix indicates extended temperature range -40C to +125C. If your application only requires -40C to +85C (industrial), the "-I" suffix parts (e.g. PIC16F722-I/ML) are typically lower cost and have identical electrical specs in the same package. Verify the BOR (brown-out reset) voltage configuration bits match your supply rail - default is usually fine but should be checked against the application note AN555.
For the 28-pin UQFN (ML) package, route all I/O lines on outer layers and avoid running signal traces beneath the IC. Use Microchip's MPLAB X with the PIC16F722 device support package and configure CONFIG words for the desired oscillator (internal 16 MHz is the default) and watchdog settings before generating code. For low-power designs, disable unused peripherals in firmware before entering sleep to achieve sub-100 nA current.
Compliance Information
RoHS and lead-free per Microchip product page. The -E extended temperature range is suitable for industrial and non-automotive applications; AEC-Q100 qualified variants should be sourced separately from Microchip's automotive-grade portfolio.
