PIC16LF1907-E/MV Overview
An 8-bit microcontroller (MCU) is a single-chip processor that integrates a CPU, Flash program memory, RAM, and peripherals on one die, executing instructions one byte at a time. PIC microcontrollers use a modified Harvard RISC architecture with separate program and data buses, which historically delivered higher code density and deterministic interrupt latency than CISC alternatives. Within the broader taxonomy, the PIC16LF1907 belongs to the PIC16 family -> 8-bit PIC MCUs -> microcontrollers -> embedded processors -> semiconductors.
Key features include a 20 MHz internal oscillator, 14 KB of self-programmable Flash (8K x 14 words), 512 bytes of RAM, 256 bytes of EEPROM, an integrated LCD controller with up to 116 segments, a 10-bit ADC with up to 14 channels, multiple Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART) and I2C/SPI peripherals, and Microchip's nanoWatt XLP sleep currents as low as 20 nA. The 40-UQFN package provides a compact, lead-free footprint suited to space-constrained consumer and industrial designs.
The device uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, allowing each Flash location to hold one 14-bit PIC instruction. This produces measurable code-density advantages over 8-bit instruction MCUs from 8051-class competitors. The integrated LCD driver supports both static and multiplexed bias modes, eliminating external segment drivers for small-display modules such as appliance front panels and metering readouts.
Typical applications include battery-powered sensor nodes, household appliance user interfaces with LCD readout, industrial metering, IoT edge nodes, wearable health monitors, and remote controls. The nanoWatt XLP feature set allows multi-year operation from a single coin cell when the MCU spends most of its time in Sleep.
When designing the PCB, route the 40-UQFN's exposed thermal pad (EP) to a continuous ground copper pour to provide both thermal dissipation and a low-impedance ground reference. Microchip's MPLAB X IDE with XC8 compiler, the PICkit 4 / MPLAB Snap programmers, and the MPLAB Code Configurator peripheral library accelerate firmware bring-up for this family.

Typical Applications
PIC16LF1907-E/MV is suitable for 6 applications: Battery-Powered Wireless Sensor Nodes, Household Appliance Front-Panel HMI with LCD, Industrial Utility Metering (Water/Gas/Electricity), IoT Edge Devices with Local LCD Display, Wearable Health Monitors, Universal Remote Controls with LCD.
Battery-Powered Wireless Sensor Nodes
The PIC16LF1907-E/MV is well suited to battery-powered wireless sensor nodes thanks to its 1.8V-3.6V supply range, nanoWatt XLP Sleep current down to ~20 nA, and 14 KB Flash for sensor-fusion firmware. The MCU wakes briefly to read the 10-bit ADC, transmit via an external radio, and return to Sleep, achieving multi-year coin-cell runtime. With 14 KB Flash the device comfortably fits protocol stacks for Sub-GHz radios (e.g., Microchip's MRF89X), BLE-front modules, or LoRa transceivers. The 40-UQFN (MV) footprint allows the node PCB to drop below 15 mm x 20 mm, an advantage for wearable form factors.
Recommended
Household Appliance Front-Panel HMI with LCD
The integrated LCD controller (up to 116 segments) makes the PIC16LF1907-E/MV a single-chip solution for washing machine, microwave, dishwasher, and thermostat front panels. The MCU directly drives segment-style glass LCDs via internal charge-pump contrast without a separate HT1621 driver, eliminating one BOM line. With -40C to +125C (-E grade) industrial temperature rating, the device survives appliance operating environments near heating elements. The 14 KB Flash accommodates menu-driven UI state machines, while the EUSART links to the main appliance control board.
Recommended
Industrial Utility Metering (Water/Gas/Electricity)
The PIC16LF1907-E/MV fits electricity-meter, gas-meter, and water-meter designs where battery lifetime, accurate ADC, and LCD readout matter. The 10-bit ADC with 14 channels handles multiple sensor inputs (temperature, voltage sense, tamper detection) while nanoWatt XLP keeps Sleep currents below 50 nA, supporting 10-15 year lithium-thionyl chloride battery operation. The LCD driver displays kWh, m3, or cubic-feet segments directly on the meter face. The -40C to +125C industrial grade tolerates outdoor enclosure temperatures.
Recommended
IoT Edge Devices with Local LCD Display
IoT edge nodes that show status on a small segment LCD benefit from the PIC16LF1907-E/MV's integrated LCD controller. The 14 KB Flash holds device-firmware-with-LittleFS plus an MQTT-SN or CoAP client bridging to a Sub-GHz or BLE module. Sleep currents under 20 nA combined with a 2,400 mAh Li-FeS2 primary cell deliver up to 10 years of field operation. The 40-UQFN package lets the edge PCB fit in a wall-outlet or behind a switch box.
Recommended
Wearable Health Monitors
Wrist-type pulse, SpO2, and step-counter wearables benefit from the PIC16LF1907-E/MV's low-power Sleep modes and integrated 10-bit ADC for photodiode analog front-ends. The LF supply range (1.8V-3.6V) and picoPower XLP technology enable direct Li-ion cell operation without a boost regulator. The 14 KB Flash holds a simple optical PPG algorithm, motion-counter firmware, and BLE driver thin-client. The compact 40-UQFN (5x5 mm) package keeps the wearable band profile thin and lightweight.
Recommended
Universal Remote Controls with LCD
Universal remotes with multi-protocol IR/RF + a small LCD status display are a natural fit for the PIC16LF1907-E/MV. The 14 KB Flash accommodates learned-code databases plus consumer-IR (CIR), IRRC, and Sub-GHz transmit primitives. The integrated LCD driver displays channel, volume, and battery state directly via segment LCD glass. nanoWatt XLP Sleep modes keep quiescent draw below the self-discharge rate of two AA alkaline cells for shelf life measured in years.

Key Differentiators
- Integrated LCD controller up to 116 segments (vs PIC16LF18855-I/MV)
- Lowest Sleep current in the same UQFN-40 footprint family (vs PIC16F18856-I/MV)
- Industrial -40C to +125C operating range in standard grade (vs PIC16LF1907-I/MV)
Design Notes
Estimated: at -40C to +125C industrial operation, the 40-UQFN package dissipates only the I/O leakage power (~1 mA per pin during switching) plus core dynamic current (~5 mA at 20 MHz/3.3V). With the exposed thermal pad (EP) soldered to a small ground copper pour on the PCB, the junction-to-ambient thermal resistance theta_JA of the MV package is approximately 35 C/W. Under typical battery-powered usage (Sleep duty cycle 99%, peak 5 mA active), the average power dissipation is below 1 mW; no thermal derating is required at 1.8V-3.6V operation.
Route the 40-UQFN's exposed thermal/ground pad (center pin) to a continuous ground copper pour using 0.5 mm wide thermal spokes or a fully solid pad - this provides both EMI shielding and DC ground return. Place the bypass capacitor (100 nF X7R) within 2 mm of Vdd pin 10 with a direct ground via to the EP pour. Keep the MCLR/Vpp trace short and surrounded by ground to avoid spurious resets during ESD or radiated-immunity events.
Do not connect external capacitors to the LCD segment pins; the PIC16LF1907-E/MV's LCD driver uses internal charge-pump bias generation - external caps on segment pins will distort the bias. When migrating firmware from PIC16LF1906 (28-pin SPDIP) to PIC16LF1907-E/MV (40-pin UQFN), verify that all port-C and port-D peripherals (EUSART, I2C, SPI) are reassigned correctly since pin mapping differs. Finally, ensure the Vdd rise time exceeds 50 us at power-on or enable the Power-on Reset (POR) / Brown-Out Reset (BOR) appropriately for the application.
