PIC16LF723A-E/MV Présentation
An 8-bit RISC microcontroller (MCU) is a small, self-contained computer on a single IC that combines an 8-bit CPU core with program memory, data RAM, I/O peripherals, and timers. Within the product taxonomy, the PIC16LF723A belongs to the PIC16 mid-range 8-bit MCU family -> 8-bit microcontroller -> microcontroller -> embedded controller -> semiconductor. Microchip's PIC16 mid-range architecture is one of the industry's most widely deployed MCU cores, known for its compact instruction set, deterministic interrupt handling, and broad peripheral integration suitable for both consumer and industrial applications.
The PIC16LF723A-E/MV integrates nanoWatt XLP extreme-low-power technology, multiple 8/16-bit timers with gate control, a 10-bit ADC, and enhanced USART, SPI, and I2C peripherals. The 28-UQFN (MV) package includes an exposed pad for improved thermal performance and ground bonding, and the device is specified for the -40C to +125C extended operating temperature range. Compared to the PIC16F723A variant, the LF version omits the internal LDO regulator and supports direct supply from a 1.8 V source, eliminating the need for an external VCAP decoupling capacitor and simplifying low-voltage designs.
Typical applications include battery-powered sensor nodes, low-power IoT edge devices, consumer appliances, LED lighting controllers, remote controls, and small-form-factor industrial automation modules where board space, power efficiency, and integrated peripherals outweigh the need for higher CPU performance.
When designing with this device, place the decoupling capacitor as close as possible to the VDD pin and ensure the exposed pad on the UQFN package is soldered to a sufficient ground copper pour for thermal dissipation. Use the internal oscillator to minimize external component count, and leverage XLP sleep modes for battery-operated designs.

Applications typiques
PIC16LF723A-E/MV convient pour 6 applications: Battery-Powered IoT Sensor Nodes, Consumer Appliance Control Boards, LED Lighting Controllers, Remote Control and HMI Devices, Industrial Sensor Transmitters, Automotive Interior Accessories.
Battery-Powered IoT Sensor Nodes
The PIC16LF723A-E/MV fits battery-powered IoT sensor nodes because of its 1.8 V to 3.6 V supply range and nanoWatt XLP extreme-low-power technology delivering sleep currents below 1 uA. Its 7 KB Flash hosts sensor-fusion or protocol-stack firmware while the 25 I/O pins interface analog sensors via the 10-bit ADC and digital sensors via SPI or I2C. Typical duty-cycled operation extends coin-cell battery life to multi-year timeframes, and the 28-UQFN (MV) footprint is small enough for sub-15 mm sensor PCBs.
Recommandé
Consumer Appliance Control Boards
The PIC16LF723A-E/MV suits consumer appliance control boards such as coffee makers, blenders, and washing-machine user interfaces where 8-bit MCU performance is sufficient. The 25 I/O drive keypads, LED indicators, and triac/relay controls; the 7 KB Flash accommodates user-interface state machines; and the 20 MHz core handles PWM for motor-speed or heater control loops. The -40C to +125C operating range survives under-hood or near-heater environments, and the 28-UQFN package saves PCB area versus SOIC alternatives.
Recommandé
LED Lighting Controllers
The PIC16LF723A-E/MV is well-matched to LED lighting controllers including dimmable bulbs and architectural RGBW fixtures. Its PWM peripherals and 20 MHz core generate multi-channel 16-bit PWM at low overhead, while the 7 KB Flash stores dimming curves, color-mixing algorithms, and DMX-512 or DALI protocol stacks. The 1.8 V to 3.6 V supply aligns with step-down converter outputs, and the 25 I/O drive MOSFET gate drivers and zero-cross detectors without external logic.
Recommandé
Remote Control and HMI Devices
The PIC16LF723A-E/MV powers IR remote controls, thermostat keypads, and small human-machine interfaces. Its nanoWatt XLP sleep mode drops quiescent current below 1 uA, preserving battery life between button presses, while its 20 MHz core wakes quickly to handle IR carrier generation or debounced keypad scanning. The 7 KB Flash accommodates protocol code (NEC, RC-5, or proprietary), and the 25 I/O drive matrix keypads and status LEDs without external I/O expanders.
Recommandé
Industrial Sensor Transmitters
The PIC16LF723A-E/MV fits industrial 4-20 mA loop-powered sensor transmitters and small PLC I/O modules. The -40C to +125C operating range tolerates factory-floor temperatures, and the 10-bit ADC digitizes 4-20 mA or 0-10 V analog inputs. The 7 KB Flash hosts linearization, fault-detection, and HART or Modbus slave stacks; the 25 I/O drive opto-isolated outputs; and the 1.8 V to 3.6 V supply aligns with 24 V loop-power step-down outputs.
Recommandé
Automotive Interior Accessories
The PIC16LF723A-E/MV suits automotive interior accessories such as seat controllers, ambient lighting drivers, and dashboard switch panels. The -40C to +125C operating range meets automotive interior temperature requirements, and the 25 I/O scan switch matrices and drive LED indicator chains. The 7 KB Flash stores debounce, fade, and diagnostic firmware; the 1.8 V to 3.6 V supply aligns with post-LDO 3.3 V rails; and the 28-UQFN package fits tight PCB enclosures.

Principaux différenciateurs
- No internal LDO regulator for simpler low-voltage designs (vs PIC16F723A-E/MV)
- Larger program memory than 722A family (vs PIC16LF722A-E/MV)
- Extended temperature grade for harsh environments (vs PIC16LF723A-I/MV)
Notes de conception
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 9) and a 10 uF bulk capacitor near the IC. Connect the exposed thermal pad (EP) on the bottom of the 28-UQFN package to a low-impedance ground pour with at least 4 thermal vias to the internal ground plane for heat dissipation. Avoid routing high-speed signals directly under the QFN body to reduce parasitic coupling.
Estimated: at 20 MHz active mode with 3.3 V supply, the PIC16LF723A-E/MV draws approximately 3-5 mA typical. Leverage nanoWatt XLP sleep modes (typical current below 1 uA) for battery-powered designs; configure unused peripherals to off and disable the ADC when not in use. The LF variant does not require a VCAP capacitor, simplifying low-voltage designs versus the PIC16F723A counterpart.
The PIC16LF723A-E/MV does not include the internal LDO regulator of the PIC16F723A variant - do not connect a VCAP capacitor. Ensure the MCLR reset pin (if used externally) has a 10 kohm pull-up to VDD. When using ICSP programming, pins RB6/RB7 are shared with the clock/data lines and may need isolation resistors if external circuitry is connected.
