PIC16F19176T-I/PT 개요
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. It sits in the embedded system hierarchy between simple logic ICs and 32-bit application processors: PIC16F19176T-I/PT > 8-bit MCU > microcontroller > integrated circuit > semiconductor. XLP variants extend battery life to months or years through sleep currents under 1 µA and on-chip peripherals that wake the core on demand.
Key features include a 12-bit ADC with 2 DAC channels, low-power comparator (LP COMP), PWM, CCP, CWG (Configurable Logic Cell), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), and RTCC (Real-Time Clock/Calendar). The integrated LCD driver with charge pump eliminates external bias generation, supporting 4 common x up to 46 segments. PIC16F19176T-I/PT operates across 2.5 V to 5.5 V over the industrial -40 °C to +85 °C range.
The device leverages an enhanced mid-range 16-bit instruction set with 14-bit opcodes, providing deterministic interrupt latency. Hardware math accelerators and CLC cells offload logic from the CPU, while Core Independent Peripherals let tasks run without waking the core. PPS allows post-build pin remapping, easing PCB layout changes late in development.
Typical applications include battery-powered metering with LCD readout, e-paper / segment LCD thermostats, portable medical monitors, IoT sensor nodes with displays, and HVAC controllers. The combination of integrated charge pump and 256-byte EEPROM suits sealed units where firmware parameters must persist without battery backup.
For power-sensitive designs, verify the active current at the operating MIPS rate and the deep-sleep current with peripherals disabled. The TQFP-44 package supports hand-solderable prototyping; production typically uses 100 % reeled T&R.

일반적인 애플리케이션
PIC16F19176T-I/PT 적합 용도: 7 애플리케이션s: Battery-Powered Energy Meter with LCD, Smart Thermostat with Segment LCD, Portable Medical Monitor, IoT Sensor Node with Display, Industrial HVAC Zone Controller, Automotive Aftermarket Display Module, Electronic Shelf Label (ESL) Base Station.
Battery-Powered Energy Meter with LCD
PIC16F19176T-I/PT suits battery-powered metering where the integrated LCD charge pump drives a 4-common x 46-segment display directly from a single 3 V cell. Its XLP sleep current below 1 µA extends coin-cell life to multi-year ranges, while the 12-bit ADC and 2x DAC channels digitize CT/VT sensor outputs and generate analog transmit signals. The 28 KB Flash accommodates IEC 62053 billing algorithms and the 256-byte EEPROM stores tamper flags and meter constants without backup battery.

Smart Thermostat with Segment LCD
The 44-pin TQFP PIC16F19176T-I/PT runs HVAC thermostat control loops with the integrated LCD driver eliminating an external display bias circuit. RTCC keeps wall-clock time during brownouts, the 12-bit ADC reads thermistor bridge outputs, and the low-power comparator wakes the core on temperature threshold crossings. PPS allows the same PCB to be reworked for different keypad layouts late in development. PPS + CLC reduce external logic ICs around the display driver.
추천
Portable Medical Monitor
Portable patient monitors use PIC16F19176T-I/PT's 32 MHz core for real-time SpO2 / pulse signal processing while the XLP idle modes preserve battery life between measurements. The 12-bit ADC samples PPG photodiode waveforms and the 2x DAC channels drive the LED bias currents in a closed-loop configuration. 2 KB SRAM holds moving-window FIR filter taps and 28 KB Flash stores the trend-logging code with IEC 62304 documentation hooks.
추천
IoT Sensor Node with Display
Wireless IoT nodes with on-device segment LCD readouts leverage PIC16F19176T-I/PT for housekeeping plus display refresh while a companion radio handles connectivity. The charge pump drives the LCD without boosting the supply, and the 32 MHz CPU runs MODBUS or LoRaWAN AT command sets alongside sensor sampling. CLC cells implement glue logic between sensor interrupts and the radio's busy line, offloading the CPU and reducing firmware complexity in low-power edge nodes.
추천
Industrial HVAC Zone Controller
Zoned HVAC controllers deploy PIC16F19176T-I/PT to drive a multi-digit LCD, read multiple NTC thermistors via the 12-bit ADC, and switch triacs via PWM outputs. The RTCC schedules setback temperature profiles, and EEPROM stores installer configuration across power cycles. The 44-pin TQFP exposes sufficient I/O for up to 5 triac drives and keypad matrix scanning without needing external mux ICs.
추천
Automotive Aftermarket Display Module
Although PIC16F19176T-I/PT is not AEC-Q100 qualified, it suits aftermarket automotive accessories (gauge clusters, tire-pressure displays) where OEM-grade qualification is not required. The integrated LCD charge pump drives reflective TN displays without inverter circuitry, and the 32 MHz core refreshes multi-segment readouts at 30 Hz. For OEM-grade applications, migrate to PIC16F19176-E/PT (extended temperature) plus an AEC-Q100 qualified MCU.
추천
Electronic Shelf Label (ESL) Base Station
ESL gateways use PIC16F19176T-I/PT to drive a small segment status LCD and orchestrate sub-GHz radio packets to thousands of label tags. The XLP sleep modes keep idle current under 1 µA between radio bursts, and the 28 KB Flash accommodates custom MAC-layer firmware stacks. PPS remaps the SPI/UART lines between the radio and external EEPROM without board respins.

설계 노트
Estimated: PIC16F19176T-I/PT active current at 32 MHz / 3.3 V is approximately 5 mA from the datasheet family typical curves. Sleep current with peripherals disabled drops below 1 µA (XLP nanoWatt). For battery-powered metering, duty-cycle the MCU active time so the average current stays below 100 µA. Use RTCC + LP comparator as wake sources to avoid polling loops, and verify the actual sleep current on the bench as datasheet figures are typical at 25 °C only.
Place the 100 nF VDD decoupling capacitor within 3 mm of each VDD pin and a bulk 10 µF ceramic within 10 mm. The TQFP-44 has four VDD/VSS pairs (pins 1/8, 20/19, 30/29, and one shared); each pair must be independently decoupled to prevent logic errors during LCD charge-pump switching. The LCD segment traces should be routed with guard traces to VSS or kept short to reduce display ghosting, especially for low-frequency COM scans below 60 Hz.
Do not skip the MCLR pull-up resistor; the MCLR pin (pin 43) requires a 10 kΩ pull-up to VDD for normal operation, otherwise the part remains in reset. When using ICSP programming, ensure no capacitor larger than 1 nF on ICSPCLK/ICSPDAT (RA1/RA0) lines, otherwise high-voltage programming may fail. The LCD charge pump requires the LCD module to be enabled and the pump configured before LCD segments will display, even if the panel is connected.
For designs with the SMT (Signal Measurement Timer) capturing high-frequency signals, route the SMT input trace orthogonally to switching LCD segment traces and keep it under 25 mm to minimize crosstalk. The 12-bit ADC accuracy degrades with source impedance above 10 kΩ; use a buffer amplifier or ensure the sensor output impedance is below 5 kΩ. Add a 100 nF cap directly at the ADC input pin when sampling low-frequency analog signals to limit charge-injection kick from the S&H capacitor.
TQFP-44 has 0.8 mm pitch pads with thermal pad optional. Use NSMD (non-solder-mask defined) pads to improve soldering yield and add teardrops on fine-pitch traces. Place the ICSP connector at the board edge for programming access without disassembling the product, and keep crystal traces (if using external XTAL) within 5 mm of the OSC pins with a guard ring to VSS to limit EMI coupling into the LCD segment lines.
