PIC16LF724T-I/PT - 8-bit MCU, 7KB Flash, 20MHz, nanoWatt XLP | Microchip
MPN: PIC16LF724T-I/PT ✓ Hoạt độngPIC16LF724T-I/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and a rich set of peripheral interfaces such as ADC, timers, communication ports, and GPIO. Within the broader taxonomy, the PIC16LF724 sits under: microcontroller -> 8-bit MCU -> PIC16 architecture -> PIC16F family -> low-power 'LF' variant. The 'LF' prefix denotes an extended voltage range (1.8 V to 3.6 V for the LF part), which is critical for battery-powered designs that previously required a separate voltage regulator.
Key features include 7KB Flash program memory, 256 bytes of RAM (typical for this family), a 12-channel 8-bit ADC, multiple PWM modules, USART, MSSP (SPI/I²C), and Microchip's nanoWatt XLP™ extreme-low-power technology for sleep currents in the nanoamp range. The 20 MHz internal oscillator enables designs without an external crystal, reducing BOM cost and PCB area.
Typical applications include consumer electronics, low-power battery-powered sensors, white goods and HVAC control interfaces, simple motor control, LED lighting controllers, and low-cost IoT edge nodes. The wide operating voltage and low-power modes make the part especially suitable for energy-harvesting applications.
When designing with this device, ensure proper decoupling on VDD with a 0.1 µF ceramic capacitor placed as close to the pin as possible, and follow Microchip's recommended layout for ICSP programming pins. The 44-TQFP package offers generous I/O for a low-end MCU and is footprint-compatible with other PIC16F/LF parts in the same family.

Ứng dụng tiêu biểu
PIC16LF724T-I/PT phù hợp cho 6 Áp dụngs: Battery-Powered Sensor Nodes, Consumer Appliance Control (White Goods), HVAC and Thermostat Controllers, LED Lighting Controllers, Industrial Control and Signal Conditioning, Low-Cost IoT Edge Nodes.
Battery-Powered Sensor Nodes
The PIC16LF724T-I/PT's 1.8-3.6 V operating range and nanoWatt XLP technology make it ideal for battery-powered wireless sensor nodes. With typical sleep currents in the nanoamp range and a 16 MHz internal oscillator eliminating external crystals, the design can run for years on a single CR2032 or 2× AA cell. The integrated 8-bit ADC, multiple timers, and MSSP SPI/I²C peripherals allow direct interface to temperature, humidity, and motion sensors without external glue logic.

Consumer Appliance Control (White Goods)
The PIC16LF724T-I/PT is well-suited for white-goods control boards in washing machines, dishwashers, refrigerators, and microwave ovens. Its 7 KB Flash holds typical user-interface state machines and motor-control loops, while the PWM modules drive brushless DC or universal motors. The 44-TQFP provides enough GPIO for keypad scanning, LED/LCD drive, and relay switching. Industrial -40 to +85 °C temperature rating supports the harsh thermal environment behind a control panel.
Được đề xuất
HVAC and Thermostat Controllers
For HVAC and thermostat designs, the PIC16LF724T-I/PT provides the 8-bit ADC needed to read thermistor or RTD temperature sensors, PWM channels for proportional valve or fan control, and the LF 1.8-3.6 V range for direct battery backup during power outages. The nanoWatt XLP sleep modes keep quiescent current under 100 nA, extending battery backup lifetime for system clocks and schedules. The 44-TQFP package allows generous I/O for keypad, display, and relay outputs.

LED Lighting Controllers
The PIC16LF724T-I/PT is ideal for entry-level LED lighting controllers, including dimmable bulbs, RGB controllers, and architectural fixtures. Its PWM modules generate accurate dimming signals, while the LF voltage range supports direct operation from constant-current driver supplies. nanoWatt XLP enables standby power well below 100 mW, helping designs meet energy-star and EU Ecodesign standby requirements. The 20 MHz CPU executes DMX-512 or DALI soft-stack easily.

Industrial Control and Signal Conditioning
In industrial panels, the PIC16LF724T-I/PT serves as a low-cost signal-conditioning and I/O-expansion processor. The 8-bit ADC scans 4-20 mA loop inputs, the PWM outputs drive solid-state relays, and the USART/MSSP provide isolation-friendly digital links to upstream PLCs. The -40 to +85 °C industrial temperature rating and robust 44-TQFP package suit factory-floor environments, while the LF voltage range simplifies battery-backed event-logger designs.

Low-Cost IoT Edge Nodes
For simple IoT edge nodes, the PIC16LF724T-I/PT runs at the edge of an MQTT or CoAP stack, aggregating sensor data before sending via an attached Wi-Fi or LoRa module over USART/SPI. The 7 KB Flash is sufficient for basic JSON serialization, sensor drivers, and a small TCP/HTTP helper library. The LF 1.8-3.6 V range allows direct connection to a 3.3 V regulator rail without level shifters, reducing BOM cost in volume.

- Identical die to PIC16LF724-I/PT with tape-and-reel packaging (vsPIC16LF724-I/PT)
- Smaller Flash vs 14 KB siblings, but lower cost (vsPIC16LF727T-I/PT)
Ghi chú thiết kế
Place a 0.1 µF ceramic decoupling capacitor as close as possible to each VDD pin, with a 10 µF bulk capacitor at the board's supply entry point. For battery-powered designs, add a series ferrite bead or small resistor between battery and VDD to limit inrush during hot-plug events. Decoupling reduces digital switching noise coupling into the analog ADC inputs.
Keep the ICSP programming pins (RB6/ICSPCLK and RB7/ICSPDAT) accessible on the PCB - either through test pads or a 2×3 0.1" header. Microchip's MPLAB debug tools require these pins free for in-circuit programming and debugging. Avoid routing high-speed signals under or near the oscillator traces to prevent clock jitter.
Do not exceed the absolute maximum VDD of 4.0 V (LF) or 6.5 V (F) or the part will be damaged. Configure unused GPIO pins as outputs (driving low) or inputs with internal pull-ups enabled - never leave them floating as analog inputs, which wastes current and may oscillate. The LF variant's 1.8 V minimum must be respected; design margin for cold-temperature battery voltage sag is essential.
