PIC16F19176T-I/MV Overview
What is an 8-bit microcontroller? An 8-bit microcontroller is a single-chip computer that processes data in 8-bit chunks and integrates a CPU, memory, and peripherals on one die. PIC® microcontrollers from Microchip use a modified Harvard RISC architecture. The XLP™ (eXtreme Low Power) family targets battery-powered applications with deep-sleep currents measured in nanoamperes. Microcontrollers in this class sit hierarchically under: MCU -> embedded processor -> semiconductor device.
Key features include an integrated LCD driver with charge pump, 12-bit ADC2 (Analog-to-Digital Converter) with computation, a 5-bit DAC, low-power comparators, multiple PWM/CCP/CWG/SMT/ZCD peripherals, Peripheral Pin Select (PPS) for flexible signal routing, and a Real-Time Clock/Calendar (RTCC). The XLP architecture delivers sleep currents below 50 nA typical.
The device operates across 2.5 V to 5.5 V, supports up to 32 MHz internal oscillator, and offers 36 I/O pins with high-current sink/source capability. On-chip Core Independent Peripherals (CIPs) allow hardware-based state machine control, offloading tasks from the CPU to reduce power and code complexity.
Typical applications include battery-powered LCD consumer devices, IoT sensor nodes with displays, smart thermostats, wearable health monitors, and industrial HMI panels. The integrated charge pump and LCD bias generation eliminate external driver circuitry in many designs.
Designers should leverage PPS to remap digital peripherals to any I/O, simplifying PCB layout. Place a 0.1 µF decoupling capacitor within 3 mm of each VDD pin and use the integrated charge pump for contrast stability.

Typical Applications
PIC16F19176T-I/MV is suitable for 6 applications: Battery-Powered LCD Thermostat, Wearable Health Monitor with Display, IoT Sensor Node with Local Display, Industrial HMI Control Panel, Smart Meter with LCD Readout, Portable Medical Measurement Device.
Battery-Powered LCD Thermostat
The PIC16F19176T-I/MV is an ideal MCU for battery-powered thermostats thanks to its integrated segmented LCD driver with on-chip charge pump, XLP nanoWatt sleep modes below 50 nA, and 12-bit ADC2 for accurate temperature sensing via NTC or RTD front-ends. The integrated charge pump eliminates external bias components, reducing BOM cost. With 28 KB Flash, designers can implement PID control loops, scheduling, and BLE command interfaces. The 5x5 UQFN-40 footprint keeps the PCB compact, while 36 high-current I/O pins drive triac outputs and segment lines. Sleep current measured at 30 nA typical enables multi-year battery life on 2x AA cells.
Recommended
Wearable Health Monitor with Display
Wearable health monitors benefit from the PIC16F19176T-I/MV's XLP architecture, delivering 30 nA sleep current critical for multi-week battery life on small lithium coin cells. The integrated LCD driver with charge pump directly drives reflective or transflective segment displays showing heart rate, step count, and battery status without external bias ICs. The 12-bit ADC2 with computation offloads filtering and threshold detection from the CPU, allowing the core to remain in sleep. PPS lets designers route I2C sensor lines and PWM haptic feedback to any pin, simplifying rigid-flex PCB layout.
Recommended
IoT Sensor Node with Local Display
The PIC16F19176T-I/MV serves as the central MCU in IoT sensor nodes that need local visual feedback. Its integrated LCD with charge pump eliminates the auxiliary display-driver circuit, while the on-chip RTCC timestamps data logging events with minimal power. The 12-bit ADC2 captures multiple analog sensor channels, and the 5-bit DAC generates analog output for sensor excitation or reference voltages. PPS-driven UART/SPI/I2C peripherals connect radios and sensors, and the 32 MHz core runs communication stacks. Core Independent Peripherals (CIPs) handle timed sensor sampling without waking the CPU, reducing average current to microamperes.
Recommended
Industrial HMI Control Panel
Industrial HMI panels use the PIC16F19176T-I/MV to drive segmented LCDs showing machine status, while 36 I/O pins interface with keypad matrixes, LED indicators, and relay drivers. The 32 MHz CPU executes control logic and Modbus RTU communication over UART, and the 12-bit ADC2 reads analog sensor inputs (pressure, level, temperature). PPS remaps peripheral outputs to align with panel layout, reducing PCB trace congestion. The industrial -40 °C to +85 °C operating range ensures reliability in factory environments. 256 bytes of EEPROM store calibration constants and user settings across power cycles.
Recommended
Smart Meter with LCD Readout
Utility smart meters leverage the PIC16F19176T-I/MV's integrated LCD driver for kWh displays and the 12-bit ADC2 for accurate power measurement via current transformers or shunt resistors. The XLP architecture delivers 30 nA sleep current, enabling 10+ year battery-backed RTC operation. RTCC maintains time-of-use billing schedules across power failures, while 256 bytes of EEPROM retains configuration. The 5-bit DAC calibrates analog front-end gain, and PWM modules drive meter-test pulse outputs. PPS routes UART for optical port communication per IEC 62056-21 standards.
Recommended
Portable Medical Measurement Device
Portable medical devices such as glucose meters and pulse oximeters benefit from the PIC16F19176T-I/MV's XLP sleep modes for battery longevity and its integrated LCD with charge pump for direct display driving. The 12-bit ADC2 provides sufficient resolution for photometric sensor readings, while low-power comparators detect threshold crossings in real time without CPU intervention. The 5-bit DAC generates reference voltages for sensor calibration, and PPS simplifies routing between sensor front-end and display driver pins. The UQFN-40 5x5 mm package enables compact handheld form factors while keeping all 36 I/O accessible for buttons and indicators.

Key Differentiators
- Integrated LCD driver with charge pump (vs PIC16F18876T-I/MV)
- Larger memory and EEPROM for parameter storage (vs PIC16F19155T-I/MV)
- Same UQFN-40 footprint across the family (vs PIC16F18446T-I/MV)
Design Notes
Place a 0.1 µF ceramic decoupling capacitor within 3 mm of each VDD pin (pins 10 and 40) and a bulk 10 µF tantalum or ceramic capacitor near the MCU. The PIC16F19176's XLP sleep current is specified at 30 nA typical; ensure no floating inputs exceed VDD+0.3V or VSS-0.3V. Use the internal Low-Power Sleep mode (RC_IDLE) for sub-microampere idle. Configure unused I/O as outputs low to minimize shoot-through current.
The UQFN-40 5x5 mm package has a central exposed thermal pad that must be soldered to a ground copper pour of at least 10 mm² for thermal dissipation and ground return. Use an 8-12 mil via array (4-9 thermal vias) under the e-pad to connect inner ground planes. Route high-speed signals (SPI, UART) on inner layers with impedance control, and keep analog traces (ADC inputs) short and guarded by ground traces on both sides to reduce crosstalk.
Avoid configuring PPS outputs to multiple pins simultaneously - each peripheral output can only route to one pin at a time. When using the LCD charge pump, ensure VLCD pin has 1 µF bypass capacitor; failure to do so causes contrast instability. The 12-bit ADC2 requires acquisition time configuration via ADACQ register - insufficient acquisition (less than 1 µs at 5V) degrades ADC accuracy. Do not exceed 32 MHz Fosc at voltages below 2.7 V; use the internal 16 MHz HFINTOSC for low-voltage operation.
