PIC16F19175T-I/MV Overview
An 8-bit microcontroller (MCU) is a programmable logic device that executes instructions from internal Flash memory at a clock rate up to 32MHz. The PIC16F19175T-I/MV sits within the broader hierarchy of microcontrollers -> 8-bit MCUs -> PIC microcontrollers -> XLP (eXtreme Low Power) family -> power management MCUs. Its integrated charge pump and LCD drive enable glass bias generation without external DC-DC circuitry, while XLP technology delivers sub-µA sleep currents for battery longevity.
Key differentiating features include 35 high-current I/O pins, a 12-bit ADC² (Analog-to-Digital Converter with Computation), a 5-bit DAC, low-power comparators (LP COMP), PWM, CCP, CWG, SMT, ZCD, and PPS (Peripheral Pin Select). The integrated LCD driver supports up to 280 segments, and the eXtreme Low Power (XLP) architecture delivers typical sleep currents in the nanoamp range, enabling years of operation from a single coin cell. The 12-bit ADC² autonomously performs signal conditioning such as averaging and threshold comparisons without CPU intervention.
Architecturally, the device uses an enhanced mid-range 8-bit CPU core with a hardware multiplier, 14-bit instruction word, and 16-level hardware stack, allowing deterministic interrupt response and predictable real-time behavior. The integrated charge pump generates the VPP LCD bias voltage from a low-voltage source, eliminating an external boost circuit. Combined with PPS routing and Core Independent Peripherals, the chip dramatically reduces firmware complexity and BOM cost.
Typical applications include battery-powered LCD meters and thermostats, IoT sensor nodes with displays, portable medical devices (glucometers, pulse oximeters), consumer appliances with segment displays, and industrial HMIs. The PIC16F19175T-I/MV is the tape-and-reel variant; the PIC16F19175-I/MV is the tray variant. Designers should also consider the pin-compatible PIC16F19155 (less Flash/RAM) and PIC16F19176 (more Flash) for memory scaling within the same package.
For PCB layout, place a 0.1µF decoupling capacitor as close as possible to each VDD pin and bond the exposed pad (EP) to a continuous ground plane for thermal dissipation. Program/debug is supported via ICSP™ on RA0/RA1, and the PPS system allows most digital peripherals to be reassigned to multiple I/O pins for flexible board routing.

Recommended
Portable Medical Devices (Glucometer / Pulse Oximeter)
The PIC16F19175T-I/MV is well suited to portable medical diagnostics such as glucometers and pulse-oximeter finger probes. Its 12-bit ADC² supports accurate electrochemical-strip readout, the 5-bit DAC provides bias generation for the optical sensor, and the integrated LCD driver displays measurement results directly on a segment glass without external bias hardware. XLP technology enables the device to idle at nanoamp currents between measurements, extending battery life across the multi-thousand-measurement lifetime typical of disposable medical form factors. The 32MHz core executes electrochemical algorithms quickly, keeping measurement latency below one second.
Recommended
IoT Sensor Node with Segment Display
The PIC16F19175T-I/MV anchors IoT sensor nodes that must show numeric or alphanumeric status on a low-power segment LCD. Its PPS (Peripheral Pin Select) flexibility allows UART, I²C, and SPI to be remapped across the 35-pin GPIO bank, simplifying PCB routing of the wireless module. XLP nanoamp sleep current plus a quick 32MHz wake-up minimize average power for battery-driven wireless sensors (LoRa, sub-GHz, BLE modules). The 12-bit ADC² handles analog sensor channels autonomously with averaging, freeing the CPU for radio stack tasks.

Key Differentiators
- Integrated LCD charge pump eliminates external bias components (vs PIC16F18877-I/PT)
- XLP nanoamp sleep current outperforms general-purpose PIC16F188xx (vs PIC16F18877-I/PT)
- Compact 40-UQFN (5x5 mm) saves PCB area vs TQFP (vs PIC16F18877-I/PT (TQFP-40))
Design Notes
The PIC16F19175T-I/MV integrates a charge pump for the LCD driver that operates from the main 2.3V to 5.5V supply. To achieve the lowest sleep current, switch off the LCD charge pump, ADC, and unused peripherals via PMD bits before entering Sleep. A typical Sleep current with full RAM retention and WDT disabled is in the sub-µA range per the Microchip datasheet, enabling multi-year coin-cell operation when duty-cycled properly.
Place a 0.1µF decoupling capacitor as close as possible to each VDD pin (11, 27, 40) and bond the central exposed pad (EP) directly to a continuous ground plane with at least 8 thermal vias for heat dissipation. The UQFN EP also serves as the electrical ground reference for the bottom of the die; inadequate EP soldering can cause thermal runaway or erratic I/O behavior. Keep trace lengths to the ICSP™ pads (RA0/RA1) under 50mm for reliable in-circuit programming.
Do not exceed 5.5V on any VDD pin or 5.5V on any I/O pin relative to VSS - the absolute maximum rating is 6.5V. The ICSP™ pins (RA0/RA1) default to analog input mode at POR; configure them as digital I/O via ANSEL registers if used as GPIO. The internal oscillator defaults to 16MHz HFINTOSC at reset; verify that OSCCON and OSCTUNE settings match your required system clock before relying on timing-critical peripherals such as UART or PWM.
The PPS (Peripheral Pin Select) system allows most digital peripherals to be remapped to any compatible digital I/O pin. Use this flexibility to route high-speed signals (SPI SCK, PWM outputs) to pins physically close to their destination, shortening PCB traces and reducing EMI. However, the LCD segment pins are fixed-position and cannot be remapped - plan your LCD glass layout around the dedicated SEG pins shown in the datasheet pinout table.
