PIC16LF1907-I/MV Descripción general
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and integrated peripherals. Within the broader taxonomy, the PIC16LF1907 is an 8-bit RISC microcontroller belonging to the PIC10/12/16/18/24 family of Microchip mid-range microcontrollers. This places it inside the power management + embedded control hierarchy of semiconductor devices used for sensor interfacing, display driving, and low-power IoT applications where the integrated LCD segment driver eliminates the need for an external LCD controller.
Key features include 14KB self-programmable Flash, 256 bytes of EEPROM, an integrated LCD driver with charge pump and contrast control, an ADC with 10-bit resolution and multiple channels, two comparators, PWM modules, and multiple communication peripherals including EUSART, I2C, and SPI. The LF designator indicates low-voltage (1.8V-3.6V) operation optimized for battery-powered applications.
The PIC16LF1907 employs a Harvard-architecture RISC core with a 14-bit instruction word. nanoWatt XLP technology integrates deep-sleep, sleep, and doze power modes plus a watchdog timer that can run from an ultra-low-power internal oscillator. The 40-UQFN package exposes an exposed thermal pad to maximize heat dissipation in surface-mount designs.
Typical applications include battery-powered LCD-based consumer electronics (thermostats, scales, metering), portable instrumentation, IoT sensor nodes, low-power remote controls, and home appliances where an integrated LCD driver reduces bill-of-materials cost.
When designing with this part, ensure the supply decoupling is generous (0.1 uF ceramic adjacent to each VDD/VSS pair) and that the LCD segment bias generation (charge pump or external resistor ladder) is matched to the panel specification; using the internal charge pump with external reservoir capacitors is the most compact configuration.

Aplicaciones típicas
PIC16LF1907-I/MV es adecuado para 6 aplicacións: Battery-Powered Thermostat with LCD Display, IoT Sensor Node with LCD Readout, Portable Medical Monitoring Device, Consumer Appliance Control Panel, Industrial Metering and Instrumentation, Remote Control with LCD Status Display.
Battery-Powered Thermostat with LCD Display
The PIC16LF1907-I/MV is well matched to battery-powered thermostats because of its integrated LCD segment driver and nanoWatt XLP sleep currents below 1 uA. Its 14KB Flash holds thermostat scheduling logic plus PID control, while the 512B SRAM retains setpoints during deep sleep. The internal LCD charge pump drives glass directly without external bias components, and the 10-bit ADC reads thermistor sensors with adequate resolution. Power dissipation estimated at less than 5 uA average in sleep mode means a 2xAA battery pack can last 2+ years.
Recomendado
IoT Sensor Node with LCD Readout
The PIC16LF1907-I/MV integrates an LCD driver that makes it ideal for IoT sensor nodes that need local data visualization. The 14KB Flash accommodates BLE/Wi-Fi co-processor command stacks, while 512B SRAM handles sensor data buffering. Its 1.8V-3.6V range matches coin-cell operation, and nanoWatt XLP sleep keeps idle current under 1 uA between measurements. Combined with the EUSART and I2C peripherals, this MCU can read sensors, format data for the radio, and display results on a 7-segment-style LCD all from one chip.
Recomendado
Portable Medical Monitoring Device
For portable medical devices such as glucose meters or pulse oximeters, the PIC16LF1907-I/MV provides reliable LCD display driving, low-power operation, and sufficient Flash for embedded algorithms. The 14KB memory holds lookup tables, calibration data, and measurement algorithms. The 10-bit ADC reads analog sensor outputs, and the integrated LCD driver displays results without external bias chips. Industrial-grade -I variant supports typical medical-device operating environments, and nanoWatt XLP sleep extends battery life of portable units.
Recomendado
Consumer Appliance Control Panel
The PIC16LF1907-I/MV drives the user-interface LCD of consumer appliances such as washing machines, microwaves, and dishwashers. Its 14KB Flash holds user-interface state machines plus sensor-processing code, while the integrated LCD driver reduces BOM cost by eliminating an external LCD controller. The wide 1.8V-3.6V range supports 3.3V regulated rails from mains adapters, and the multiple PWM channels drive motor or buzzer feedback directly.
Recomendado
Industrial Metering and Instrumentation
The PIC16LF1907-I/MV suits industrial metering applications such as energy meters or flow meters with LCD displays. The 14KB Flash holds metering algorithms plus display logic, the 256-byte EEPROM stores calibration and tamper-resistant counters, and the 10-bit ADC measures CT or shunt outputs. The integrated LCD driver displays kWh, voltage, or flow data without external controllers, and nanoWatt XLP technology enables long battery life in wireless meter designs with infrequent wake cycles.
Recomendado
Remote Control with LCD Status Display
The PIC16LF1907-I/MV is well suited for advanced remote controls that include an LCD status display (such as audio/video system controllers). Its 14KB Flash accommodates complex IR/RF protocol encoding, and the LCD driver provides channel/volume/track status without an external display controller. The 1.8V-3.6V range runs from a single CR2032 coin cell, and nanoWatt XLP sleep keeps idle current low between button presses. Two PWM channels can drive backlight and haptic feedback.

Notas de diseño
Use the nanoWatt XLP sleep modes aggressively: an idle PIC16LF1907 with LCD off draws sub-microamp current, but a 16 MHz active core can pull several mA. For battery designs, sleep between sensor reads and disable unused peripherals via PMD registers. Estimated: with 1 read per minute and 50 ms active time at 3.3V, average current stays under 10 uA from a 220 mAh CR2032.
Place a 0.1 uF ceramic decoupling capacitor adjacent to each VDD/VSS pin pair of the UQFN, plus a bulk 1 uF to 10 uF capacitor at the package's exposed pad (which must be soldered to a grounded thermal pad). Keep the crystal or external oscillator traces short and surrounded by ground to minimize EMI pickup on low-amplitude analog inputs.
Route the LCD segment lines away from high-frequency digital signals (EUSART TX, PWM outputs) to avoid display artifacts. Use the LCD segment register-locking feature during write operations to prevent partial updates. The internal charge pump requires external reservoir capacitors (typically 1 uF to 10 uF) placed close to the LCDCAP pins to minimize ripple on the LCD bias voltage.
Do not program the LF (low-voltage) variants with VDD below 2.0V during Flash erase/write operations; the datasheet requires 2.0V minimum for Flash programming even though the LF operating range goes down to 1.8V. Ensure MCLR pin (RA3) has a proper pull-up or ICSP programmer connection during reset events, and configure unused I/O pins as outputs low rather than inputs to minimize current leakage.
