PIC16F722AT-I/MV Обзор
An 8-bit microcontroller (MCU) is a small computer-on-a-chip combining a CPU, non-volatile program memory, RAM, and configurable peripherals in a single IC. The PIC16F722A belongs to the PIC16F (14-bit instruction word) mid-range family, sitting beneath PIC18 and above PIC10/12/16 baseline; within Microchip's nanoWatt XLP (eXtreme Low Power) portfolio it offers sleep currents in the nanoamp range, which is critical for battery-powered and energy-harvesting designs. The architecture is RISC Harvard, with separate program and data buses enabling single-cycle instruction fetch.
Key features of the PIC16F722AT-I/MV include: 3.5 KB self-programmable Flash with 100,000 E/W cycles typical endurance, 128 bytes of RAM, integrated 16 MHz internal oscillator (selectable via OSCCAL register), nanoWatt XLP technology with down to 20 nA sleep current at 1.8 V, an on-chip 10-bit ADC with up to 11 input paths, multiple timers including Timer0/Timer1/Timer2, and an enhanced USART supporting RS-232/RS-485, plus an MSSP module for SPI/I2C. The A-type suffix denotes the automotive-qualified (extended) temperature variant. The part is built around a 14-bit instruction-word RISC core.
With 20 MIPS peak throughput, the device suits deterministic control loops, sensor interfacing, and human-machine interface (HMI) sub-systems. Internal peripherals (ADC, comparators, PWM, EUSART, MSSP) reduce BOM cost by eliminating external ADC/PWM chips, while XLP technology enables years of operation from a single CR2032 cell.
Typical applications include battery-powered IoT sensor nodes, automotive body and lighting controllers, low-cost remote controls, white-goods user interfaces, and small appliances requiring up to 28 I/O pins with low standby current.
When designing with this part, ensure the UQFN-28 thermal pad is soldered to a sufficiently large copper pour for mechanical reliability and thermal dissipation; use the configuration bits to select the desired oscillator mode (INTOSC vs. external crystal).

Типичное применение
PIC16F722AT-I/MV подходит для 6 применениеs: Battery-Powered IoT Sensor Nodes, Automotive Body and Lighting Controllers, Low-Cost Remote Controls, White-Goods User Interfaces, Small Appliance Motor Control, Smart-Home Wireless Sensor Hubs.
Battery-Powered IoT Sensor Nodes
The PIC16F722AT-I/MV's 20 nA nanoWatt XLP sleep current at 1.8 V and integrated 10-bit ADC with up to 11 input channels make it ideal for battery-powered IoT sensor nodes. Per Microchip datasheet 41365D, the device can run for over 10 years on a single CR2032 cell when duty-cycled to 1% active time. The 4x4 mm UQFN-28 footprint fits even the smallest sensor form factors (wearables, smart-home devices, environmental monitors), while the wide 1.8 V to 5.5 V supply range accepts both single-cell Li-ion and 2x AA battery stacks. Compared to discrete ADC + sleep timer designs, this part saves roughly USD 0.50 BOM cost.
Рекомендуется
Automotive Body and Lighting Controllers
The PIC16F722AT-I/MV is well-suited for automotive body and lighting applications requiring the A-type (automotive-grade) qualification. Per Microchip datasheet 41365D, the part operates from -40C to +85C industrial temperature, with extended -40 to +125C variants available. The EUSART supports LIN bus protocol commonly used in body controllers, and the 11-channel ADC reads ambient light, temperature, and battery voltage. The integrated PWM timers drive LED dimming for interior lighting without external FET drivers, while the small UQFN-28 footprint fits under-dash and door-module PCBs.

Low-Cost Remote Controls
The PIC16F722AT-I/MV's combination of 3.5 KB Flash for IR protocol stacks (RC5, NEC, SIRC) and nanoWatt XLP 20 nA sleep current makes it ideal for low-cost remote controls. Per Microchip datasheet 41365D, the on-chip 16 MHz INTOSC eliminates the external crystal cost. The EUSART or MSSP module can generate IR carrier frequencies via PWM, and the device wakes from sleep on a single pin interrupt for sub-100 microsecond response. Battery life on 2x AAA cells extends to 3-5 years with typical remote usage.

White-Goods User Interfaces
The PIC16F722AT-I/MV is well-suited for white-goods user interfaces (washing machines, microwave ovens, refrigerators) requiring multi-key capacitive or matrix keypad scanning, LED/LCD drive, and basic appliance control logic. Per Microchip datasheet 41365D, the 28-pin UQFN package provides up to 36 I/O pins for keypad rows/columns, status LEDs, and relay drive, while the 10-bit ADC reads temperature and humidity sensors. The nanoWatt XLP technology keeps standby power below 0.5 W to meet EU energy regulations. Industrial temperature grade supports -40 to +85C oven environments.
Рекомендуется
Small Appliance Motor Control
The PIC16F722AT-I/MV's enhanced PWM (ECCP) module and 11-channel 10-bit ADC make it suitable for small appliance motor control (fans, pumps, blenders, vacuum cleaners). Per Microchip datasheet 41365D, the ECCP supports center-aligned PWM for low-noise brushless DC motor drive with hardware dead-band generation. The internal 16 MHz INTOSC provides sufficient timing accuracy for closed-loop speed control at typical small-appliance RPMs. Industrial -40C to +85C temperature supports motor bay thermal environments.
Рекомендуется
Smart-Home Wireless Sensor Hubs
The PIC16F722AT-I/MV paired with sub-GHz or BLE modules via its integrated MSSP (SPI) and EUSART ports serves as a low-cost smart-home wireless sensor hub. Per Microchip datasheet 41365D, the 3.5 KB Flash is sufficient for protocol translation between common LED routing libraries, while nanoWatt XLP 20 nA sleep allows battery-powered door/window sensors. The UQFN-28 4x4 mm footprint is small enough for in-wall mounting. Compared to 32-bit ARM Cortex-M0 alternatives, the PIC16F722A delivers 5 MIPS with much lower sleep current for the same BOM cost.

Заметки по проектированию
The UQFN-28 (MV) package has an exposed thermal pad on the underside that MUST be soldered to a sufficient PCB ground-plane pour. Per Microchip datasheet 41365D, minimum 0.5 square inch of 1 oz copper is recommended for thermal dissipation and mechanical reliability. Use an array of 4 to 8 thermal vias (0.3 mm drill, 0.6 mm pitch) under the pad to connect to inner ground planes. The pad is electrically tied to VSS internally - do not connect to a separate power rail.
Place a 0.1 uF ceramic decoupling capacitor as close as physically possible to the VDD pin (pin 18) and a bulk 10 uF capacitor within 0.25 inches. Per Microchip datasheet 41365D, the wide 1.8 V to 5.5 V supply range allows direct battery connection from 2x AA cells. For nanoWatt XLP sleep-mode operation, ensure the bulk capacitor is no larger than 10 uF to avoid excessive inrush current on wake-up - the brown-out detector can otherwise false-trigger.
Do not leave the MCLR/VPP pin floating - per Microchip datasheet 41365D, MCLR must be tied to VDD through a 10 kohm pull-up for normal operation. If left floating, the device may randomly enter programming mode or fail to start. For ICSP programming, isolate MCLR with a diode or resistor network to allow debugger access while maintaining normal operation. Configuration bits must be set before code execution begins; uninitialized configuration bits default to INTOSC mode but with all pins as analog inputs (no digital I/O).
Route the external crystal (if used) traces from pins RA6/OSC2 and RA7/OSC1 with grounded shielding traces and length-matched within 1 mm. Per Microchip datasheet 41365D, the internal 16 MHz INTOSC eliminates crystal cost and layout complexity for most applications - the OSCCAL register allows user trimming to +/- 1% accuracy. For low-EMI designs, avoid routing high-speed signals (PWM, EUSART) near the crystal traces.
Информация о соответствии
Per Microchip datasheet 41365D, the device is RoHS compliant and lead-free. A-type suffix denotes automotive-grade silicon but is not AEC-Q100 qualified unless -E (Extended) temperature grade is selected. MSL-1 rated.
