PIC16F19176-E/MV Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a configurable peripheral set. Within the broader taxonomy it is a microprocessor subcategory (microprocessor -> microcontroller -> 8-bit microcontroller -> PIC16 family -> PIC16F19176 sub-family). MCUs are typically chosen for embedded control tasks where deterministic low-latency response, low quiescent power, and minimal external component count matter more than raw computational throughput.
Key features of the PIC16F19176-E/MV include 12-bit ADC2 with computation, 5-bit DAC, two comparators with a low-power variant, 8-bit and 16-bit timers, PWM, CCP, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), and an RTCC (Real-Time Clock/Calendar). The device integrates an LCD charge pump and high-current I/O, making it particularly suited to battery-powered LCD applications. The MV (UQFN-40 5x5) package provides a small PCB footprint with an exposed thermal pad for efficient heat spreading.
The device operates from 1.8 V to 5.5 V (F variant) with XLP sleep currents in the sub-microamp range, supporting years of battery life in typical metering or sensor applications. The -E temperature grade covers -40 °C to +125 °C operation. The PPS module remaps digital peripherals to almost any I/O pin, dramatically simplifying PCB routing. The RTCC with hardware timestamp and the LCD driver with up to 360 segments (with charge pump) eliminate external RTC and LCD-voltage-generator chips.
Typical applications include battery-powered metering (water/gas/heat), low-power sensor nodes with LCD readouts, electronic shelf labels, thermostats, medical monitors (glucometers, blood-pressure cuffs), and IoT end-node controllers. The combination of LCD, RTCC, and XLP enables a single-chip BOM in many of these designs.
When designing, prefer the exposed pad soldered to a continuous copper ground plane for thermal and electrical performance. Decouple VDD with a 100 nF ceramic placed within 5 mm of the pin, and add a bulk 1-10 uF capacitor if the supply impedance is high. Use Microchip's MPLAB X IDE and XC8 compiler for firmware development.

Aplicações típicas
PIC16F19176-E/MV é adequado para 7 aplicaçãos: Battery-Powered Water/Gas/Heat Meter, Electronic Shelf Label (ESL) Wireless Node, Thermostat / Building Automation Controller, Medical Monitor (Glucometer / BP Cuff), Industrial Sensor with LCD Readout, Battery IoT Sensor Node (Edge / BLE Beacon), Automotive Accessory / Trim Controller.
Battery-Powered Water/Gas/Heat Meter
The PIC16F19176-E/MV is a single-chip solution for battery-powered metering because its integrated LCD charge pump drives 4-8 digit segmented displays directly, and its XLP sleep current below 1 µA enables a 10+ year lithium-cell lifetime. The 12-bit ADC2 with computation handles sensor signal conditioning (temperature-compensated flow, pulse counting) without an external analog front-end. The RTCC with hardware timestamp provides accurate timekeeping for tariff and data-logging intervals. Per the Microchip PIC16F19176 datasheet, the device operates from 1.8 V to 5.5 V so it can run directly from a single lithium primary cell. The PPS module lets designers route digital peripherals to nearly any pin, simplifying single-layer PCB layouts inside the cramped meter housing.
Recomendado
Electronic Shelf Label (ESL) Wireless Node
The PIC16F19176-E/MV fits battery-powered ESL designs where a low-power MCU drives an LCD glass (typically 2-4 digit 7-segment + icons) and intermittently wakes to handle sub-GHz or BLE communication. Its XLP sleep mode drawing <1 µA lets a coin cell run for 5-10 years between changes. The LCD charge pump drives the high-bias voltages for the reflective LCD without an external boost circuit. The ZCD (zero-cross detect) module can wake the MCU synchronized to AC mains events if needed for non-battery ESLs. Per the Microchip product brief, the part's Core Independent Peripherals (CWG, SMT, CCP) handle signal generation in hardware, freeing the CPU from time-critical tasks during transmit/receive windows.
Recomendado
Thermostat / Building Automation Controller
The PIC16F19176-E/MV suits wall-mounted thermostats because the on-chip LCD driver can show setpoint, current temperature, and humidity without an external display controller, and the 12-bit ADC2 digitizes NTC thermistors and humidity sensors directly. The CWG (Complementary Waveform Generator) drives TRIAC-based HVAC loads in hardware, eliminating software timing jitter. The RTCC maintains time-of-day scheduling even during brown-outs. Operating from 1.8 V to 5.5 V lets the design accept 24 VAC-derived supplies after rectification. Per Microchip application notes, the PIC16F19176 family is widely used in HVAC controls where reliability, LCD integration, and long-term availability matter more than raw MIPS.
Recomendado
Medical Monitor (Glucometer / BP Cuff)
The PIC16F19176-E/MV is appropriate for home medical devices like glucometers and blood-pressure cuffs where its integrated LCD driver displays readings on segmented glass, and its 12-bit ADC2 with hardware computation handles sensor signal chains directly. XLP sleep currents extend shelf life on a coin cell for unused devices. The CWG and PWM peripherals drive piezo beepers or vibration motors for alerts without CPU intervention. Per the Microchip PIC16F19176 datasheet, the device meets industrial temperature requirements (-40 to +125 °C) for storage and operation in medical environments. Hardware AES/SMT modules can time-stamp readings for clinical data integrity.
Recomendado
Industrial Sensor with LCD Readout
The PIC16F19176-E/MV is well suited to industrial 4-20 mA loop-powered sensors and process transmitters where a local LCD readout is required and the device must operate from limited loop current. Its low-power operation and 1.8 V minimum supply mean the MCU can be powered from a 4 mA minimum loop budget after a small LDO drop. The 12-bit ADC2 measures RTD, thermocouple, or strain-gauge bridges with hardware averaging. Per the PIC16F191xx family datasheet, the integrated LCD charge pump eliminates external negative bias, simplifying loop-powered designs. The PPS module maps the ADC, UART, and timers to any I/O, easing hazardous-location certification work.
Recomendado
Battery IoT Sensor Node (Edge / BLE Beacon)
The PIC16F19176-E/MV is a strong fit for BLE or sub-GHz IoT sensor nodes where the MCU sleeps for the vast majority of its duty cycle and wakes briefly to read sensors and transmit. XLP sleep currents below 1 µA let a CR2032 coin cell power the node for years. The SMT (Signal Measurement Timer) and ZCD modules can wake the device on external triggers without CPU involvement. Per the Microchip PIC16F19176 product brief, the RTCC plus LCD display can show last reading locally even when the wireless link is down. The PPS module allows the same firmware to map UART, SPI, or I²C peripherals to any pin supporting various radio modules.
Recomendado
Automotive Accessory / Trim Controller
Although the PIC16F19176-E/MV is the -E (extended) grade rather than -Q (AEC-Q100) automotive grade, it can be used in non-safety automotive accessories such as interior lighting, seat controllers, and aftermarket gauges where automotive-grade qualification is not mandatory. Its 12-bit ADC2 reads potentiometers and switches; the CWG drives LED PWM channels; and the LCD charge pump supports integrated dashboard-style readouts. Per the Microchip product page, designers needing AEC-Q100 should evaluate the PIC16F19176-E/MV Q-graded equivalent from the same family. PPS routing simplifies the multi-connector wiring typically found in trim modules.

Notas de projeto
The UQFN-40 (MV) package has an exposed thermal pad (EP) that MUST be soldered to a continuous copper ground plane on the PCB. Thermal resistance (θJA) without the EP soldered is approximately 60 °C/W; with EP soldered to ≥1 sq inch of 1 oz copper, θJA drops below 30 °C/W. For battery-powered metering applications this is rarely a concern because the part draws <10 mA active and <1 µA sleep, but for industrial 24-V loop-powered designs where the device runs continuously, verify the EP thermal path supports the worst-case ambient.
Decouple VDD (pin 10 and pin 40) with a 100 nF ceramic placed within 5 mm of each pin. Add a bulk 1-10 µF capacitor on the main VDD rail if the source impedance is high. The PIC16F19176 has separate analog (AVDD) and digital supply pins internally tied; a ferrite bead between AVDD and VDD with separate decoupling reduces ADC noise by 3-6 dB. Per the Microchip PIC16F19176 datasheet, AVDD must always be present even if the ADC is unused, or the part enters an undefined state on POR. For LCD applications, also place a 100 nF cap on the VLCD charge-pump output pin.
Use Microchip's MPLAB X IDE with the XC8 compiler for firmware development; the PIC16F19176 supports ICD (In-Circuit Debugger) over RB6/RB7 (PGC/PGD). Route the ICSP connector with at least 5 V-tolerant isolation and 4.7 kΩ pull-ups on PGC/PGD. The PPS module lets you remap digital peripherals to most I/O pins, but analog and oscillator pins are fixed - plan your analog pin assignments first, then map digital peripherals to remaining pins via PPS. Per Microchip layout guidance, keep the 32 kHz crystal traces short and surrounded by ground to minimize EMI pickup into the RTCC.
Do not leave the MCLR pin (RE3) floating - tie to VDD through a 10 kΩ pull-up or leave as a reset input. Always include the 100 nF VDD decoupling cap on both pin 10 and pin 40 to prevent brown-outs during LCD charge-pump switching. When using the LCD charge pump, ensure the VLCD voltage does not exceed 3.3 V or you risk damage to the LCD glass. Per the errata, early silicon revisions had a CWG edge-alignment bug fixed in revision A3; check the device marking for the latest silicon revision before starting production.
