PIC16LF723AT-I/ML Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory (Flash), data memory (RAM), and peripheral set on one die. Within the broader semiconductor taxonomy it sits as: microcontroller -> embedded MCU -> RISC microcontroller -> 8-bit MCU -> semiconductor. The PIC16 core implements a Harvard-architecture RISC instruction set, which is widely adopted in cost-sensitive and low-power applications because each instruction typically completes in one oscillator cycle, enabling deterministic timing with modest clock rates.
Key features of the PIC16LF723AT-I/ML include 7KB (4K x 14 words) Flash, 192 bytes RAM, an integrated 8-channel 8-bit ADC, and ultra-low-power nanoWatt XLP technology that supports sleep currents in the microampere range. It also exposes MSSP (SPI/I2C), USART, and capture/compare/PWM peripherals, plus an internal 16MHz oscillator that eliminates the need for an external crystal on most designs.
Architecturally, the PIC16LF723A family uses a 14-bit instruction word with a 36-instruction set, allowing dense code storage in the 4K-word Flash array. The LF (low-voltage, low-power) silicon process supports 1.8V minimum operation, making the part compatible with single-cell Li-ion or two-AA battery chemistries where the 'F' (mid-voltage) variants would otherwise be unusable below 2.0V.
Typical applications include consumer remote controls, battery-powered IoT sensor nodes, low-cost home appliances, white-goods user interfaces, and LED lighting controllers. The 28-QFN package suits space-constrained PCB layouts while exposing 25 GPIO pins for sensors, keypads, or display drivers.
When designing with this device, budget the ADC's 8-bit resolution carefully against sensor accuracy requirements; for thermistor or potentiometer front-ends this is typically sufficient, but strain-gauge or precision instrumentation will benefit from a 12-bit PIC16F1xx upgrade. The exposed thermal pad must be soldered to a grounded copper pour for electrical and thermal performance.

Typische Anwendungen
PIC16LF723AT-I/ML ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Consumer Remote Control (IR/RF), White-Goods User Interface / HMI, Low-Cost Smart Lighting Controller, Industrial Sensor Transmitter, Portable Health and Fitness Device.
Battery-Powered IoT Sensor Node
The PIC16LF723AT-I/ML is well matched to wireless battery sensor nodes because its nanoWatt XLP silicon delivers sub-microampere sleep currents and it operates down to 1.8 V from a single Li-ion cell. The 16 MHz internal oscillator eliminates an external crystal, reducing BOM cost on small sensor PCBs. With 25 GPIO and an 8-channel 8-bit ADC, it can read temperature, humidity, and battery-voltage sensors while idle in sleep for most of the duty cycle, then wake to transmit and return to sleep.
Empfohlen
Consumer Remote Control (IR/RF)
In handheld remote controls, the PIC16LF723AT-I/ML's 1.8-3.6 V operation directly supports two AAA cells across their discharge curve. Its 192-byte RAM is sufficient for IR or sub-GHz RF protocol stacks (RC5, NEC, or simple proprietary OOK/FSK). The 7 KB Flash holds protocol libraries plus application code, and the 16 MHz internal oscillator provides accurate carrier generation. The 28-QFN package is small enough to fit behind a keypad PCB, preserving the slim industrial design typical of consumer remotes.
Empfohlen
White-Goods User Interface / HMI
For washing machines, microwaves, and induction cooktops, the PIC16LF723AT-I/ML offers 25 GPIO to drive 7-segment displays, keypads, and LED indicators while reading rotary encoders or touch keys. Its CCP/PWM peripheral can control indicator backlight dimming or buzzer tones, and the MSSP/SPI/I2C peripherals interface to LED drivers or auxiliary display controllers. The -40 C to +85 C industrial temperature range and 1.8-3.6 V operation suit appliance environments with regulated 3.3 V rails.
Empfohlen
Low-Cost Smart Lighting Controller
The PIC16LF723AT-I/ML drives smart-LED constant-current controllers and PWM dimming for white or RGB lighting strips. Its PWM and timer peripherals generate high-resolution dimming signals, while its 8-bit ADC reads ambient-light sensors for closed-loop brightness control. nanoWatt XLP sleep lets battery-backed emergency luminaires operate for years. The 28-QFN footprint supports compact driver PCB layouts inside the lamp base or fixture junction box.
Empfohlen
Industrial Sensor Transmitter
In 4-20 mA loop-powered or RS-485 sensor transmitters, the PIC16LF723AT-I/ML provides the local control and ADC conversion needed for thermistor, RTD, or pressure-sensor front-ends. Its USART peripheral directly drives RS-485 transceivers for Modbus RTU or proprietary protocols, and the 1.8-3.6 V supply aligns with 3.3 V regulated industrial rails. The 7 KB Flash holds calibration coefficients and linearization math for accurate sensor reporting over industrial temperature ranges.
Empfohlen
Portable Health and Fitness Device
The PIC16LF723AT-I/ML fits wearable fitness bands and portable medical peripherals where sub-microampere sleep and a small footprint matter most. Its 25 GPIO drives simple LCD segments, vibration motors, and BLE/wireless companion modules over UART. With 192 bytes RAM and 7 KB Flash, it handles step counting, simple heart-rate timing, or BLE command relay in a tiny 28-QFN package. The 1.8-3.6 V supply matches single-cell Li-ion/polymer batteries common in wearable form factors.

Wichtigste Unterscheidungsmerkmale
- Lowest-voltage LF silicon in the PIC16F723 family (vs. PIC16F723AT-I/ML)
- Larger Flash density than PIC16LF722 (vs. PIC16LF722-I/ML)
- More balanced memory/peripheral set than PIC16LF727 (vs. PIC16LF727-I/ML)
Designhinweise
Estimated: at 3.3 V VDD, 16 MHz active, the PIC16LF723AT-I/ML draws roughly 3-4 mA typical; in XLP sleep with peripherals off, quiescent current drops to sub-microampere levels. For battery-powered designs, use the 'idle' or 'sleep' modes aggressively and gate external sensors via a GPIO-controlled load switch so the MCU is the only wake-up source. Always include a 100 nF decoupling capacitor within 5 mm of VDD and a 10 uF bulk capacitor on the supply rail.
The 28-QFN exposed thermal pad MUST be soldered to a grounded copper island at least as large as the pad to provide the IC's main ground reference and thermal path. Use 0.1 mm (4 mil) via stitching on a 0.5 mm pitch under the EP. Place the decoupling capacitor within 5 mm of the VDD pin and route oscillator traces short and direct, with a guard ground on either side to reduce EMI coupling into the internal oscillator.
Do not use the PIC16LF723AT-I/ML on a 5V supply - it is the LF (low-voltage) variant and absolute maximum VDD is 3.6V. For 5V systems, select the PIC16F723AT-I/ML. Configuration fuses are write-locked on first programming; use the in-circuit debugger to recover an over-locked device. The 8-bit ADC requires a clean VREF; tie unused ADC inputs to a known voltage (VSS or VDD) to avoid floating-input leakage current.
