PIC16LF18875-I/MV - 8-Bit 32MHz XLP MCU 14KB Flash 40-UQFN
MPN: PIC16LF18875-I/MV ✓ NakahandaPIC16LF18875-I/MV Ulas
An 8-bit microcontroller (MCU) is a self-contained computing subsystem on a single silicon die that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), EEPROM, and a mix of analog and digital peripherals. The PIC16F188xx family sits at the intersection of the PIC microcontroller hierarchy: PIC16 -> mid-range 8-bit MCU -> Microchip 8-bit portfolio -> Microcontrollers -> Integrated Circuits. The "XLP" designation indicates eXtreme Low Power peripheral design, including nanoWatt XLP technology that lets the device sleep in the nanoamp range while retaining state.
Key features include a 10-bit ADC with computation (ADC2), a 5-bit/8-bit DAC, comparators, PWM, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), HLT (Hardware Limit Timer), WWDT (Windowed Watchdog Timer), SCAN/CRC, ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), EUSART, and SPI/I2C. The wide peripheral set reduces external component count and BOM complexity.
This part is suited for ultra-low power 4-20 mA analog, electronics metering, low-power wireless power system control, energy harvesting, and general-purpose 8-bit embedded systems. The active NV meter buffer and pin select offer both active-high enable.

Tipikal na mga Gamit
PIC16LF18875-I/MV ay nararapat para sa 7 aplikasyons: Battery-Powered IoT Sensor Nodes, Electronic Metering and 4-20 mA Loops, Low-Power Motor Control, Energy-Harvesting and Remote Controls, LED Lighting and Smart Lighting, Industrial Sensing and Process Control, Consumer Electronics and Appliance Control.
Battery-Powered IoT Sensor Nodes
The PIC16LF18875-I/MV is ideal for battery-powered wireless sensor nodes because of its 1.8-3.6 V supply range, nanoWatt XLP sleep currents below 50 nA, and integrated 10-bit ADC2 with computation that offloads filtering from the CPU. The 14 KB Flash and 1 KB RAM comfortably fit BLE/Zigbee stack fragments plus sensor calibration data, and the EUSART/SPI/I2C peripherals directly interface common sub-GHz or BLE modules. With PPS flexibility, designers can remap peripheral I/O to any pin to optimize PCB routing while preserving the 40-pin UQFN footprint shared with the rest of the family.

Electronic Metering and 4-20 mA Loops
In electronic metering applications, the PIC16LF18875-I/MV delivers precise analog measurement via its 10-bit ADC2 with oversampling, hardware accumulators, and zero-cross detect (ZCD) for AC line frequency monitoring. The 14 KB Flash supports metering algorithms plus calibration constants, while the 256 B EEPROM stores non-volatile trim and tamper logs. The CWG (Complementary Waveform Generator) and PWM peripherals drive isolated commutation in power-metering front-ends, and PPS allows the SPI to be routed directly to an external energy-measurement AFE without remapping glue logic.
Inirekomenda
Low-Power Motor Control
The PIC16LF18875-I/MV is well suited to low-power brushless DC and stepper motor control through its PWM and Complementary Waveform Generator (CWG) peripherals, which generate dead-band-corrected complementary gate-drive waveforms. With 32 MHz CPU, the MCU closes torque-control loops at high update rates while leaving headroom for housekeeping. The comparator, ZCD, and ADC2 channels synchronize back-EMF sensing and current measurement with hardware triggers, minimizing software latency. The 40-pin UQFN footprint provides enough I/O for three-phase gate drivers plus encoder or Hall-sensor feedback.
Inirekomenda
Energy-Harvesting and Remote Controls
For energy-harvesting designs such as self-powered remote controls or wireless light switches, the PIC16LF18875-I/MV's nanoWatt XLP sleep current (sub-100 nA typical) extends harvested-energy budgets to years of standby. The integrated SMT (Signal Measurement Timer) captures timing events during deep sleep without waking the CPU, and the WWDT/PMD power-management modules let peripherals run independently. PPS routing enables direct connection to a piezoelectric harvester or RF transmitter without external logic, and the wide 1.8-3.6 V supply tolerates the variable output of rectified harvesters.
Inirekomenda
LED Lighting and Smart Lighting
The PIC16LF18875-I/MV powers smart LED drivers using its 16-bit PWM and CWG peripherals to drive constant-current LED strings with smooth dimming and flicker-free operation. The 10-bit ADC2 monitors ambient light and LED current for closed-loop brightness control, while I2C interfaces the lighting fixture to BLE/Zigbee modules for wireless control. The 5/8-bit DAC provides reference voltages for analog dimming interfaces. PPS flexibility reassigns PWM outputs to any pin to simplify multi-channel driver layout while staying within the same 40-pin UQFN footprint across product variants.
Inirekomenda
Industrial Sensing and Process Control
In industrial sensor transmitters and process-control peripherals, the PIC16LF18875-I/MV provides reliable operation across -40 to +85 °C with industrial-grade EMI/ESD robustness. Its 10-bit ADC2 with hardware averaging delivers stable measurements for thermocouples, RTDs, and 4-20 mA loops, while the SCAN/CRC module validates firmware integrity in safety-critical applications. The EUSART supports RS-485 half-duplex industrial protocols, and the CWG/PWM peripherals drive solenoid and relay outputs. The 14 KB Flash hosts Modbus/RTU stack plus application logic, and PPS flexibility simplifies mixed-signal PCB layout.
Inirekomenda
Consumer Electronics and Appliance Control
The PIC16LF18875-I/MV is a strong fit for consumer appliances such as coffee machines, washing machines, and kitchen hoods because of its integrated peripherals - comparators for water-level sensing, ADC2 for temperature, and PWM for motor control. The 14 KB Flash holds graphical UI state machines plus housekeeping, and PPS flexibility simplifies mixed-signal board layouts. The 1.8-3.6 V supply range supports direct Li-ion battery operation, while the 40-pin UQFN footprint offers enough I/O for keypad, sensors, and triac drives in a compact 5x5 mm package.

Talaan ng Disenyo
Estimated: at VDD = 3.3 V and active CPU at 32 MHz, the PIC16LF18875 draws approximately 6 mA; in sleep with retention, nanoWatt XLP mode drops this to < 50 nA. Decouple VDD with a 100 nF X7R ceramic placed within 5 mm of the VDD pin and add a 10 uF bulk capacitor near the regulator. Avoid routing high-speed digital signals over the analog VDD trace to prevent ADC2 noise injection.
The 40-pin UQFN package has a low thermal resistance (~30 C/W) thanks to the exposed pad. Solder the EP to a 3x3 mm copper pour on the top layer for best heat dissipation. For battery applications where the MCU spends most of its life in sleep, junction self-heating is negligible, but in active motor-control loops at 32 MHz with all peripherals on, ensure the EP is fully soldered to keep Tj below 125 C.
Use Microchip's recommended 5x5 mm UQFN-40 land pattern with NSMD pads and 0.4 mm pitch. Route PPS-remappable signals on inner layers to keep the top side reserved for analog input routing. Place the ICSP programming header (ICSPDAT/ICSPCLK on RB7/RB6 by default, but PPS-reassignable) near the board edge for in-circuit programming access during manufacturing test.
Do not exceed 3.6 V on VDD - the PIC16LF18875 is the low-voltage LF variant and will be damaged above 3.6 V. The PIC16F18875 (non-LF) is required for 5 V designs. Also remember to configure PPS before assigning peripheral functions to pins; leaving PPS at default after reset routes peripherals to fixed pins and may collide with your pinout.
When routing SPI at > 4 MHz or I2C at > 400 kHz, keep trace lengths under 50 mm and add 22-33 ohm series resistors at the driver pins to dampen ringing. The SCAN/CRC peripheral can validate code integrity at boot - configure it in production firmware to detect Flash corruption from ESD events, especially in industrial installations.
