PIC16LF18875-E/MV Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, data memory, I/O ports and on-chip peripherals such as timers, ADC, communication interfaces and clock generation. 8-bit MCUs like the PIC16F18875 sit at the entry level of embedded computing, optimised for cost-sensitive and deterministic real-time control tasks where power consumption, code simplicity and peripheral integration matter more than raw compute throughput. XLP variants add sleep currents below 1 uA and multiple power-saving modes for battery-operated designs.
Key features of the PIC16LF18875 include 36 I/O pins, a 10-bit ADC, two 8-bit DACs, two comparators, PWM/SCCP/MCCP capture-compare-PWM modules, MSSP supporting SPI and I2C, an EUSART for UART, and a CRC/SCAN engine for memory integrity. The device operates from 1.8V to 3.6V with active current in the microamp range when peripheral functions are selectively disabled. Its instruction set is fully backward-compatible with the mid-range PIC16 core, and the CIPs allow functions like signal conditioning, waveform generation and sensor interfacing to run without CPU intervention.
Typical applications include IoT sensor nodes, battery-powered wireless controls, wearables, home automation peripherals, low-end consumer electronics, and industrial sensor interfaces. The wide peripheral set and 32 MHz performance enable tasks such as driving LED matrices, scanning keypads, decoding sensor protocols, and managing low-power RF links.
When designing with the PIC16LF18875, plan pin allocation carefully because the 40-pin UQFN shares several peripheral functions on alternate pins. Use Microchip's MPLAB X IDE and the XC8 compiler for development, and verify sleep current budgets early because I/O pin leakage and weak pull-ups can dominate in deep-sleep designs.

Typical Applications
PIC16LF18875-E/MV is suitable for 6 applications: IoT Wireless Sensor Nodes, Battery-Powered Wearable Devices, Home Automation Sensor Hubs, Industrial Control Sensor Interface, Consumer Electronics Remote Controls, Automotive Body Electronics.
IoT Wireless Sensor Nodes
The PIC16LF18875-E/MV is well suited for IoT sensor nodes because its XLP technology achieves sub-microamp sleep currents and its 32 MHz active CPU processes sensor data quickly before returning to sleep. The integrated 10-bit ADC reads analog sensors directly, while MSSP (SPI/I2C) connects to digital sensors and EUSART handles asynchronous radios. With 14 KB Flash and 1 KB SRAM, the MCU hosts small protocol stacks (BLE beacon firmware, LoRaWAN MAC) and CIP-based sensor preprocessing without waking the core, extending battery life to 1-5 years on a coin cell.
Recommended
Battery-Powered Wearable Devices
The PIC16LF18875-E/MV's 1.8 V minimum operation and XLP sleep modes make it ideal for wearables powered by CR2032 coin cells or thin-film Li-ion batteries. Its 5x5 mm UQFN-40 footprint fits compact wrist-worn form factors, and the 36 I/O pins drive small OLED displays, LEDs and haptic feedback elements. Peripheral Pin Select remaps functions across pins, simplifying PCB routing in space-constrained layouts. The LF suffix ensures the part stays within spec down to 1.8 V battery cutoff, extending usable runtime by 15-25% versus 2.3 V minimum F variants.
Recommended
Home Automation Sensor Hubs
In home automation hubs the PIC16LF18875-E/MV acts as a low-power edge node aggregating data from motion, temperature, humidity and door/window sensors. The MSSP runs I2C sensor buses, while the EUSART provides a wired link to a parent Zigbee/Z-Wave module or Wi-Fi gateway. The CRC/SCAN engine monitors Flash integrity for tamper detection, and the 10-bit ADC reads analog light sensors directly. Compared to a 32-bit MCU, the PIC16LF18875's 8-bit architecture and 32 MHz throughput keep cost and active power low for high-volume hub deployments.
Recommended
Industrial Control Sensor Interface
The PIC16LF18875-E/MV serves as a 4-20 mA loop-powered sensor transmitter in industrial control systems. The 10-bit ADC digitizes the loop current while two 8-bit DACs and two comparators provide diagnostic thresholds. Operating temperature range -40C to +125C suits factory floor environments. CIPs (Configurable Logic Cell, CRC/SCAN) implement autonomous fault detection without CPU intervention, ensuring deterministic response within microseconds. The 1.8 V-3.6 V supply is well matched to 4-20 mA loop-powered architectures drawing 3-4 mA quiescent current.
Recommended
Consumer Electronics Remote Controls
The PIC16LF18875-E/MV is a strong fit for remote controls where battery life and cost drive BOM decisions. XLP sleep currents below 1 uA let a coin-cell remote run 5+ years. The integrated comparators debounce mechanical buttons, the MSSP drives IR LEDs via SPI-controlled PWM, and the EUSART supports two-way control protocols. The 40-pin UQFN package fits slim form factors. CIP-based button scanning offloads CPU work, allowing the core to remain in sleep until a wake-up event fires.
Recommended
Automotive Body Electronics
While the E suffix indicates -40C to +125C automotive-grade temperature range, automotive designs requiring AEC-Q100 qualification should verify with Microchip. In body electronics modules (window lifters, mirror controllers, seat adjusters) the PIC16LF18875-E/MV's CIPs drive PWM motor control while the core supervises LIN bus communication. The 32 MHz CPU processes LIN frames in real time, and the 14 KB Flash fits protocol stacks plus application firmware. Designers should note that AEC-Q100-qualified PIC variants carry the -VAO suffix; the standard E temperature grade is not AEC-Q100 certified.

Key Differentiators
- Extended low-voltage operation down to 1.8 V (vs PIC16F18875-E/MV)
- Extended temperature range -40C to +125C (vs PIC16LF18875-I/MV)
- XLP sleep current below 1 uA (vs PIC16F18875-E/MV)
Design Notes
The 40-UQFN (MV) 5x5 mm package has a relatively small thermal pad. Estimated: at 32 MHz active and 3.3 V supply, the PIC16LF18875 draws approximately 4-5 mA active, so power dissipation is ~15 mW and junction temperature rise is negligible. However, in high-IO-toggle applications the I/O current contribution can dominate - plan for up to 100 mA total VDD/GND load when many I/O are switching simultaneously and ensure adequate copper pour on the exposed pad.
Place a 0.1 uF decoupling capacitor within 2 mm of each VDD pin and a single 10 uF bulk capacitor at the package's exposed pad. The 40-UQFN has multiple VDD/VSS pairs; ensure each pair has its own 0.1 uF. Use a ground pour under the package and stitch vias around the exposed pad for thermal and electrical performance. Avoid running high-speed signals under the package to minimize coupling.
Do not assume PIC16LF18875 and PIC16F18875 firmware are interchangeable in the voltage range below 2.3 V - the LF variant extends operation to 1.8 V but the F variant will brown-out below 2.3 V. Also, when migrating to PIC16LF18855-E/MV (28-pin), verify peripheral pin-out because the 18855 has only 25 I/O and different pin assignments. Use Microchip's MPLAB Code Configurator (MCC) to manage peripheral pin mapping when porting across the family.
Route the ICSPDAT/ICSPCLK pins to a 2x3 or 1x6 header for in-circuit programming. Reserve the MCLR pin as input-only with a 10 kohm pull-up to VDD. For low-power sleep designs, ensure all unused I/O pins are configured as outputs low (not inputs floating) to minimize input-leakage current - this is the most common cause of unexpected 10-50 uA sleep current in PIC16LF designs.
Compliance Information
RoHS compliant per Microchip product page. E temperature grade is -40C to +125C but is NOT AEC-Q100 qualified; for AEC-Q100 automotive applications, use the -VAO suffix variant. The LF suffix indicates low-voltage 1.8 V-3.6 V operation with XLP technology.
