PIC16F19176-E/PT 概要
An 8-bit PIC microcontroller is a Harvard-architecture RISC CPU optimized for embedded control, sitting in the hierarchy: microcontroller -> embedded processor -> semiconductor IC. The 'PIC16' family balances low power, low cost and rich peripherals for consumer, industrial and IoT designs. Within PIC, the 'F' suffix denotes FLASH program memory, while '19176' identifies the part's specific peripheral mix.
Key features include: integrated charge pump for direct LCD bias generation, 12-bit ADC with computation (ADC2), 5-bit DAC, low-power comparators, PWM/CCP/CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detector), PPS (Peripheral Pin Select), RTCC (Real-Time Clock Calendar) and high-current I/O for direct LED drive. Per the Microchip product page, the device is especially suited to battery powered LCD applications.
The device integrates hardware-based CIP blocks that run autonomously without CPU intervention, freeing the core for power management or comms. XLP modes (Sleep, Doze, Idle, RTC-calibrated wake) deliver nanoWatt-class standby currents, making the PIC16F19176-E/PT a strong fit for sealed, battery-only metering or wearable designs where energy harvesting is impractical.
Typical applications include battery powered LCD panels, smart thermostats, IoT sensor nodes with displays, medical glucose and infusion meters, industrial HMI panels, and electronic shelf labels. The wide operating voltage range and integrated charge pump simplify LCD bias design.
When designing with the PIC16F19176-E/PT, allocate the PPS module carefully to avoid pin-function conflicts, and use Microchip's MPLAB X IDE with XC8 compiler for code development. The 44-TQFP footprint provides generous I/O access for segment-heavy LCD panels.

主な用途
PIC16F19176-E/PT の用途: 6 件s: Battery-Powered LCD Thermostat, Industrial HMI Panel, Smart Metering & Utility Endpoints, Medical Infusion / Glucose Meter, IoT Sensor Node with Display, Electronic Shelf Label (ESL) Gateway.
Battery-Powered LCD Thermostat
The PIC16F19176-E/PT fits battery-powered LCD thermostats because its integrated charge pump derives LCD bias directly from a single 1.5V/3V cell stack, removing external boost components. Per Microchip, the XLP architecture delivers nanoWatt sleep current, allowing the device to idle on the RTCC while periodically waking to refresh the LCD and read the ADC2 temperature channel. With 28KB flash and 2KB SRAM the part comfortably hosts HVAC control firmware, segment drivers, scheduling tables and BLE state-machine shells. PPS simplifies board routing when the LCD flex is placed on the opposite side of the PCB from the sensor.
おすすめ
Industrial HMI Panel
The PIC16F19176-E/PT serves industrial HMI panels by combining an integrated LCD controller, 12-bit ADC2 with computation and the Core Independent Peripheral (CIP) set in a single 44-TQFP footprint. Per the Microchip product page, the PWM/CCP/CWG and SMT blocks run autonomously, freeing the 8-bit core to manage Modbus RTU or HMI key scanning. The 32MHz core keeps response latency low even when refreshing large segmented displays, and the -40C..+125C 'E' temperature grade tolerates cabinet-mounted deployment near motors or heaters.
おすすめ
Smart Metering & Utility Endpoints
The PIC16F19176-E/PT is well suited to smart metering endpoints because of its 256-byte EEPROM for tariff/calibration data, RTCC for time-of-use billing and integrated LCD charge pump for segmented metrology displays. According to Microchip, the XLP sleep current is in the nanoAmpere range, which is critical for sealed utility meters that must run 10+ years on a primary cell. The 12-bit ADC2 with computation handles high-accuracy sensor readings, while PPS keeps the PCB layout compact for the small meter enclosures typical of gas and water endpoints.
おすすめ
Medical Infusion / Glucose Meter
The PIC16F19176-E/PT fits medical infusion pumps and glucose meters because of its XLP nanoWatt sleep modes that extend battery life between doses, plus the integrated 12-bit ADC2 for accurate sensor readouts. Per Microchip, the Core Independent Peripherals (CIP) such as SMT and CWG drive haptic buzzers and LCD segments without CPU load. The 28KB flash holds dosing tables and BLE state machine code, while 256 bytes of EEPROM retain calibration constants across battery swaps. The 44-TQFP package gives plenty of I/O for segment-rich LCDs and keypad scanning.
おすすめ
IoT Sensor Node with Display
The PIC16F19176-E/PT anchors IoT sensor nodes with on-device displays by integrating LCD, ADC2 and CIP blocks in one die. Per the Microchip product page, PPS lets designers reassign peripheral pins to escape-route around a compact antenna keep-out, while the 32MHz core runs a small sensor hub plus a LoRaWAN or BLE stack shell. The XLP architecture's nanoWatt sleep current combined with RTCC wake allows years of operation from a primary cell, and the 44-TQFP (PT) footprint is large enough for rich segmented indicators without external display drivers.
おすすめ
Electronic Shelf Label (ESL) Gateway
The PIC16F19176-E/PT fits ESL gateways and base stations because of its rich timer set (SMT, Timer0/1/2, RTCC) and PWM/CCP/CWG blocks for RF sub-GHz modulation. Per Microchip, the integrated LCD charge pump and segmented LCD driver support local debug/displays on the gateway PCB. With 28KB flash and 2KB SRAM the part runs RF protocol stacks plus LCD/UI code, and the 44-TQFP package provides enough I/O for buttons, LEDs, RF switch control and external comms buses. XLP sleep allows the gateway to idle between label updates, reducing retail energy budgets.

設計ノート
Estimated: at 32MHz, VDD=3.3V and all peripherals enabled, the PIC16F19176-E/PT draws ~7 mA active and ~50 nA in deep sleep with RTCC. Disable unused peripherals in firmware via PMDx registers before entering XLP sleep, since idle ADC2 and SMT blocks retain bias currents. For coin-cell designs, gate the LCD charge pump with the LCDEN bit only during refresh windows to drop average Iq below 1 uA.
Place VDD/VSS pins 8, 18, 28 of the 44-TQFP with their own 100nF + 10uF local bypass network within 3 mm of each pin pair. Avoid routing high-frequency LCD segment traces under the exposed pad; the TQFP PT package has no EP, so thermal dissipation is through the die flag - use copper pours on inner layers stitched with 0.3 mm thermal vias. PPS reassignments must respect Schmitt-trigger thresholds when remapping I2C or UART to general-purpose pins.
Do not assume the LCD charge pump handles arbitrary bias voltages - the PIC16F19176-E/PT supports static, 1/2, 1/3, 1/4 bias with up to 4 common lines and limited segment count per mux ratio. Verify pin assignments for VLCD1/VLCD2/VLCD3 vs SEGx multiplexing in the datasheet pin summary before laying out the LCD flex. Also, the 'E' temperature grade is the extended industrial -40C..+125C; for cost-sensitive consumer designs the 'I' grade PIC16F19176-I/PT is interchangeable but limited to +85C.
Route the OSC1/OSC2 crystal traces within 5 mm of the MCU with a guard ring tied to VSS. If using the internal HF oscillator (default), leave OSC1/OSC2 as GPIO via PPS but still place 100nF on the nearest VDD/VSS pair. The 44-TQFP footprint's center-pad-free package simplifies routing but slightly raises thermal resistance; for ambient >85C designs derate the internal ADC2 reference by 5% or switch to external VREF+.
