PIC16LF19175T-I/MV Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals on one die; the PIC16 core uses a modified Harvard RISC architecture with 14-bit instruction words optimized for deterministic execution and low power consumption. XLP (eXtreme Low Power) technology from Microchip adds sleep currents in the nanoampere range, making this family especially suited for energy-harvesting and battery-backed applications.
Key features include an integrated LCD driver with charge pump, 12-bit ADC2 with Computation, 5-bit and 8-bit DACs, low-power comparator, PWM, CCP, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), and RTCC (Real-Time Clock Calendar). The device provides Core Independent Peripherals (CIPs) that operate without CPU intervention, freeing the core for higher-level tasks.
Hardware security is enhanced with CRC/SCAN, a Hardware Limit Timer (HLT), and a Windowed Watchdog Timer (WWDT). The 40-pin UQFN (MV) package offers a compact 5x5 mm footprint suitable for space-constrained designs while maintaining full peripheral access through the device's 36 I/O pins.
Typical applications include battery-powered LCD user interfaces, IoT sensor nodes, home automation panels, medical monitoring devices, and industrial control HMIs. The integrated charge pump allows direct LCD glass drive without external boost circuitry.
When designing with this MCU, place a 0.1 µF decoupling capacitor as close as possible to the VDD pin and a 10 µF bulk capacitor near the UQFN exposed pad, which must be soldered to a ground plane for thermal dissipation. PPS enables flexible pin assignments but requires configuration lock-out to prevent runaway code.

IoT Sensor Node with Edge Processing
The PIC16LF19175T-I/MV is well-suited to IoT sensor nodes requiring local signal conditioning before wireless transmission. Its Core Independent Peripherals (CIPs) including the SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), and 12-bit ADC2 with Computation perform autonomous sensor sampling and RMS/peak detection without waking the CPU, reducing average current by orders of magnitude. The 14KB Flash accommodates small protocol stacks (e.g., Modbus RTU slave), while 1KB RAM handles sensor buffers. Combined with an external sub-GHz or BLE transceiver over UART/SPI, the MCU enables multi-year battery-life sensor endpoints.
Recommended
Home Automation Control Panel
In home automation control panels and wall-mounted thermostats, the PIC16LF19175T-I/MV integrates the LCD display driver, capacitive-touch sensing via the CVD peripheral, multiple PWM channels for lighting/blind control, and a hardware RTCC for scheduling - all on one chip. The 32 MHz CPU and 14KB Flash support user-interface graphics state machines and Modbus/KNX-over-UART bridges. The 5x5 mm UQFN package keeps the panel slim while the industrial -40C to +85C temperature range ensures reliable operation in unheated indoor environments.
Recommended
Industrial Sensor Transmitter
The PIC16LF19175T-I/MV's 12-bit ADC2, low-power comparator, and ZCD (Zero-Cross Detect) peripheral make it ideal for 4-20 mA loop-powered industrial sensor transmitters. The ZCD enables AC line-voltage zero-crossing measurement for phase-controlled loads, while the low-power comparator supports fast signal-level detection. Hardware CRC/SCAN and Windowed Watchdog Timer (WWDT) add functional safety required in industrial installations. The 1.8V minimum supply supports operation from loop currents down to 3.5 mA with proper regulation.
Recommended
Medical Monitoring Device
The PIC16LF19175T-I/MV's XLP nano-Watt technology and integrated 12-bit ADC2 with Computation are well-suited for portable medical monitoring devices such as pulse oximeters, glucose meters, and digital thermometers. Sleep currents below 100 nA extend battery life across multi-month monitoring periods. The 5-bit and 8-bit DACs provide waveform generation for sensor excitation, while the Hardware Limit Timer (HLT) and WWDT add medical-grade safety features. The 40-pin UQFN (5x5 mm) package suits compact handheld enclosures.
Recommended
Smart Appliance User Interface
For smart appliance HMIs such as washing-machine front panels, dishwasher control boards, and refrigerator displays, the PIC16LF19175T-I/MV provides integrated LCD drive, multiple PWMs, CWG (Complementary Waveform Generator) for motor-drive signaling, and CCP for capture/compare tasks. The 32 MHz CPU and 1KB RAM support segment-LCD UI state machines and communication stacks (e.g., UART-based appliance bus). PPS simplifies PCB routing when I/O assignments change between product variants.

Key Differentiators
- Newest-generation Core Independent Peripherals (CIPs) (vs PIC16LF18875-I/MV)
- Compact 40-pin UQFN 5x5 mm with exposed pad (vs PIC16LF1906-I/SP)
- Same-package flash upgrade path to 28KB / 56KB (vs PIC16LF19176T-I/MV)
Design Notes
The PIC16LF19175T-I/MV's XLP nano-Watt technology enables deep-sleep currents below 100 nA with RTCC running, ideal for battery-powered designs. Use the internal 32 kHz LFINTOSC for RTCC in sleep to minimize power; switch to the 32 MHz HFINTOSC only when CPU activity is required. A 0.1 µF ceramic decoupling capacitor must be placed within 3 mm of the VDD pin, and a 10 µF bulk capacitor should be placed adjacent to the UQFN exposed pad for stable operation across the 1.8 V to 3.6 V supply range.
The 40-pin UQFN (5x5 mm) package uses an exposed thermal pad on the underside that MUST be soldered to the PCB ground plane for both electrical grounding and thermal dissipation. Per Microchip application note AN2584, the pad requires at least 9 thermal vias (0.3 mm drill, 1.0 mm pitch) connecting to inner ground planes. The pad improves thermal performance by 35% versus a non-connected pad, which is critical when running the CPU continuously at 32 MHz.
Use PPS (Peripheral Pin Select) to reassign digital peripherals (UART, SPI, PWM) to any I/O pin after RESET, simplifying PCB layout when board variants share the same MCU. Lock the PPS configuration in firmware using the PPSLOCK register before sensitive operations to prevent runaway code from remapping peripherals. Route the analog ADC2 inputs away from switching PWM traces to avoid coupled noise, and place the AVSS pin on a clean analog ground island.
Do not exceed the absolute maximum VDD of 4.0 V (ESD-sensitive on the LF variant). The configuration bits must be programmed for the internal oscillator before code execution begins - if external clock mode is selected but no crystal is present, the MCU will hang. The ICD (In-Circuit Debugger) header requires dedicated ICSPCLK/ICSPDAT pins; do not reassign these via PPS if you intend to debug in-circuit.
Compliance Information
