PIC16F19176-I/MV 概要
An 8-bit microcontroller (MCU) is a programmable processor that executes instructions one byte at a time using an 8-bit data path. The PIC16 family sits in the broader taxonomy of microcontrollers -> embedded processors -> semiconductors, while XLP (eXtreme Low Power) variants add deep-sleep current management for coin-cell and energy-harvesting applications. The 8-bit PIC16 core provides deterministic instruction execution and a Harvard architecture that simplifies real-time control loops.
Key features include a 2.3V to 5.5V supply range, 32 MHz internal oscillator, 12-bit ADC2 with computation, 5-bit DAC, two comparators with selectable references, peripheral pin select (PPS), and an integrated LCD driver supporting up to 320 segments. The device also provides a charge pump that maintains LCD contrast even at low battery voltage, high-current I/O for direct LED drive, and Core Independent Peripherals (CIPs) such as CWG and SMT that offload timing tasks from the CPU.
Technically, the PIC16F19176 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and 16-level hardware stack. Its XLP architecture supports sleep currents in the sub-microamp range with RTCC and peripherals running, and the integrated LCD charge pump allows glass driving down to 1.8V VDD when configured appropriately. The 40-pin UQFN package minimizes PCB area while exposing the full peripheral set, and PPS enables flexible peripheral-to-pin assignment without re-routing the board.
Typical applications include battery-powered medical glucose meters, IoT sensor nodes with LCD readouts, industrial HMI panels, smart thermostats, home appliance user interfaces, and portable instrumentation. The wide operating voltage and integrated LCD charge pump simplify single-coin-cell designs that need a glass display.
When designing, place decoupling capacitors within 2 mm of each VDD/VSS pair and follow the recommended ground-return layout for the LCD charge pump capacitors. The PPS feature allows peripheral reassignment post-build, so reserve unused pins in the schematic as a routing safety net.

Battery-Powered Medical Glucose Meter
The PIC16F19176-I/MV fits battery-powered medical glucose meters because its integrated LCD charge pump sustains glass display contrast down to 1.8 V on a single coin cell, eliminating external boost circuitry. The XLP sleep current below 1 uA extends battery life across multi-month shelf and active-use windows. The 12-bit ADC2 with computation performs accurate glucose-strip analog readings with hardware-averaged oversampling, while the 28 KB Flash hosts Bluetooth Low Energy command stacks, calibration tables, and UI logic. The 40-pin UQFN 5x5 mm footprint keeps the meter small enough for handheld use.
おすすめ
IoT Sensor Node with LCD Readout
The PIC16F19176-I/MV suits IoT sensor nodes that display local measurements on a glass LCD because the integrated charge pump removes the need for a separate negative bias generator, lowering BOM cost. Its 2.3 V to 5.5 V supply range directly supports 3.3 V regulated rails from harvested energy. The RTCC maintains accurate time-stamping in sleep mode at nanoamp currents, while PPS allows flexible UART/SPI pin routing for the wireless transceiver. With 28 KB Flash, the MCU fits LoRaWAN or Zigbee stack plus sensor fusion code.
おすすめ
Smart Thermostat with Glass Display
The PIC16F19176-I/MV is ideal for smart thermostats because its LCD charge pump drives 200+ segment glass displays directly from a 3 V supply, while CWG and SMT peripherals generate quiet zero-cross TRIAC drive for HVAC loads. The 12-bit ADC2 reads thermistor bridges with hardware oversampling for sub-0.1 C accuracy, and the 5-bit DAC provides offset trimming for analog front-ends. The 32 MHz CPU executes PID loops with 125 ns instruction resolution, and 2 KB SRAM buffers scheduling data without paging.
おすすめ
Industrial HMI Control Panel
The PIC16F19176-I/MV fits industrial HMI panels because its high-current I/O directly drives LED indicators, piezo buzzers, and key-matrix inputs without external drivers, reducing BOM cost. Core Independent Peripherals (CWG, SMT, PWM) execute waveform generation in hardware, freeing the CPU for Modbus or CANopen protocol handling. The 28 KB Flash holds the UI state machine plus communication stacks, and the 40-pin UQFN package exposes enough I/O for 4x4 key matrices and 7-segment displays. RTCC provides scheduled logging timestamps.
おすすめ
Portable Handheld Instrumentation
The PIC16F19176-I/MV suits portable handheld instruments because its XLP architecture achieves sub-microamp sleep between measurement bursts, allowing weeks of battery life on 2x AA cells. The 12-bit ADC2 with computation supports accurate sensor readings at 100 ksps, while the integrated LCD charge pump drives multi-segment displays directly. PPS enables flexible probe-interface pin assignments without PCB redesign, and the 32 MHz CPU performs FFT or RMS calculations in real time for power-quality and DMM products.
おすすめ
Home Appliance User Interface
The PIC16F19176-I/MV fits washing-machine and dishwasher user interfaces because its integrated LCD drive with charge pump displays cycle status, time remaining, and error codes directly on glass without external bias generation. The high-current I/O sinks LED arrays and relay coils directly, simplifying drive circuitry. The RTCC keeps accurate cycle timing across power interruptions, and 2 KB RAM holds washing-program state variables. The 32 MHz CPU manages UART communication with the main motor controller via PPS-routed pins.

設計ノート
The PIC16F19176-I/MV XLP architecture achieves sub-1 uA sleep current with RTCC running, enabling multi-year coin-cell operation. To minimize active current, switch the CPU to the 32 kHz LFINTOSC during idle loops and gate unused peripherals via PMD registers. The integrated LCD charge pump allows direct battery connection, but the charge-pump flying capacitor (typically 1 uF X7R) must be placed within 3 mm of the VLCD pins to minimize ripple.
Place all VDD/VSS decoupling capacitors (100 nF X7R) within 2 mm of the respective pins. The UQFN-40 package exposes a central thermal pad that must be soldered to a ground copper pour of at least 25 mm^2 to meet thermal and electrical performance. Avoid routing high-speed digital signals (PWM outputs, oscillator traces) directly beneath the LCD charge-pump capacitors to prevent injected noise on the bias rails.
When using Peripheral Pin Select (PPS), reserve unused I/O pins in the schematic as routing flexibility for late-stage peripheral reassignment. The ICSP pins (RB6/RB7) should remain accessible for in-circuit programming and debugging; do not assign them to output-only peripherals. For LCD glass, route SEG and COM traces with equal length where possible to minimize ghost-segment effects and keep traces away from high-current switching nodes.
Do not exceed 5.5 V on any pin; the PIC16F19176-I/MV is not 5 V tolerant on all pins. Always configure unused I/O as outputs driven low to minimize sleep current. When migrating from PIC16F18855, remember that the LCD charge-pump capacitor values differ - consult the PIC16F19176 datasheet for the exact VLCD flying capacitor selection, otherwise contrast will degrade at low battery voltages.
