PIC16F1947T-I/PT 概要
What is a microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), peripherals and I/O. In the system hierarchy it sits above discrete logic and below full microprocessors, providing programmable digital control. The PIC16F1947T-I/PT belongs to Microchip's enhanced mid-range 8-bit PIC16 family, a Harvard-architecture device using separate program and data buses for deterministic instruction execution.
Key features include a 32 MHz internal oscillator, hardware multiplier, 32-level hardware stack with overflow/underflow reset, 49 instruction set, 10-bit ADC with up to 17 channels, multiple capture/compare/PWM modules, an LCD driver supporting up to 192 segments, EUSART, MSSP (SPI/I2C), and nanoWatt XLP sleep modes with currents as low as . Code protection, ICSP (In-Circuit Serial Programming) and a wide operating temperature range make it production-ready for industrial designs.
The PIC16F1947T-I/PT uses a 14-bit instruction word with single-cycle execution (200 ns at 20 MHz, 125 ns at 32 MHz). The Harvard architecture separates 16-bit instruction fetch from 8-bit data access, eliminating the von Neumann bottleneck. The integrated LCD driver with variable bias and contrast control eliminates external LCD controller ICs, reducing BOM cost in metering and appliance designs.
Typical applications include LCD-display human-machine interfaces in white goods, battery-powered metering (electric/gas/water), industrial control panels, automotive body modules, and low-cost embedded control replacing discrete logic. The wide voltage range (2.3-5.5 V) and XLP features also make it suitable for IoT sensor nodes and remote controls.
When designing with the PIC16F1947T-I/PT, ensure decoupling caps are placed within 3 mm of VDD/VSS pins and that the ICSP pins (RB6/ICSPDAT, RB7/ICSPCLK) are accessible for in-circuit programming. The LCD bias capacitors must be sized per the segment count and bias mode chosen.

主な用途
PIC16F1947T-I/PT の用途: 6 件s: LCD Human-Machine Interface (HMI) Panels, Battery-Powered Utility Meters, Industrial Control Panels, White Goods and Appliance Controllers, Automotive Body Control Modules, Low-Cost IoT Sensor Nodes.
LCD Human-Machine Interface (HMI) Panels
The PIC16F1947T-I/PT is purpose-built for LCD HMI panels thanks to its integrated LCD driver supporting up to 192 segments across COM/SEG pins. Designers can drive dot-matrix or 7-segment LCDs without external bias resistors or controllers, reducing BOM count by 2-3 ICs. Its 28 KB Flash accommodates multi-language menus and button debouncing logic, while nanoWatt XLP sleep modes (under 100 nA typical) allow battery-backed HMI panels that retain state for years. According to the Microchip datasheet, the integrated charge pump supports 1.8-3.5 V LCD bias generation even when VDD drops below the panel threshold.
おすすめ
Battery-Powered Utility Meters
In gas, water, and electric meters, the PIC16F1947T-I/PT provides the LCD driver, ADC for sensor readout, and nanoWatt XLP sleep modes needed for 10+ year battery life. Its 32 MHz core handles pulse counting, calibration math, and TOU (time-of-use) metering algorithms, while the 1 KB RAM buffers interval data before EEPROM commit. The 2.3-5.5 V supply range supports single 3 V lithium or two AA cells, with the LCD charge pump maintaining display contrast even at end-of-life battery voltage. A typical implementation draws under 2 uA average with periodic wake-up.
おすすめ
Industrial Control Panels
The PIC16F1947T-I/PT's 17-channel 10-bit ADC reads multiple analog sensors (temperature, pressure, flow) while its CCP/ECCP modules generate PWM for valve and motor control. The EUSART provides RS-485 connectivity for Modbus RTU networks, and MSSP supports I2C sensor expansion or SPI peripheral interfacing. With 36 GPIO, a single MCU replaces 2-3 logic ICs in PLC expansion I/O modules. Industrial -40 C to +85 C operation and a robust 32-level hardware stack make it suitable for factory-floor equipment.
おすすめ
White Goods and Appliance Controllers
Washing machines, dishwashers, and microwave ovens use the PIC16F1947T-I/PT for motor control, sensor readout, and user interface LCD. The CCP/ECCP modules drive triac phase-angle control for AC loads, while the 10-bit ADC monitors temperature sensors (NTC) and water level. The integrated LCD driver eliminates the cost of separate display controllers in user-interface panels. nanoWatt XLP standby current extends energy-star compliance ratings during low-power idle states.
おすすめ
Automotive Body Control Modules
While not AEC-Q100 qualified, the PIC16F1947T-I/PT (industrial -I grade) is widely used in non-safety automotive body applications like HVAC control heads, mirror adjusters, and lighting dimmers. Its LIN-compatible EUSART enables single-wire bus communication, and the integrated LCD driver displays cabin temperature and fan settings. For AEC-Q100 qualified designs, the PIC16F1947T-E/PT (extended temperature -40 C to +125 C variant) is the recommended drop-in replacement with the same TQFP-64 pinout.
おすすめ
Low-Cost IoT Sensor Nodes
The PIC16F1947T-I/PT serves as a low-cost local controller in IoT edge nodes where full Linux/MCU modules are overkill. It handles sensor sampling, local decision logic, and drives a small status LCD. Combined with an external radio like the RN4870 (Bluetooth) or MRF24J40 (Zigbee), it creates a complete IoT endpoint. The 28 KB Flash fits basic MQTT-SN or proprietary stack implementations, while nanoWatt XLP modes enable multi-year battery operation on coin cells. Its 64-pin TQFP package provides ample GPIO for sensor fan-out.

設計ノート
Place a 100 nF decoupling capacitor within 3 mm of each VDD/VSS pin pair (the 64-pin TQFP has 5 pairs at pins 5/6, 15/16, 33/34, 43/44, 53/54). Add a bulk 10 uF tantalum or ceramic capacitor at the board-level supply input. The nanoWatt XLP sleep current of approximately 50-100 nA requires careful PCB layout - avoid leakage paths through the LCD bias network. Use battery isolation MOSFETs for designs that must achieve <500 nA total quiescent current.
Keep the LCD segment and common traces short and parallel to minimize ghosting artifacts. Route COM0-COM7 on one side and SEG0-SEG36 on the perpendicular side with 0.2-0.3 mm trace spacing. Add guard traces tied to VSS between adjacent segments if the LCD glass requires it. The VLCD pin (63) needs a 1 uF capacitor to VSS for charge pump stability - do not omit this capacitor or LCD contrast will drift.
Do not leave MCLR/RG5 (pin 60) floating - tie to VDD through a 10 kohm resistor for normal operation or to the ICSP programmer header. Configuration word settings (especially WDTE, BOREN, LVP) must be set before code protection is enabled, otherwise the device will be bricked. When migrating from the PIC16F1937 or PIC16F1946, verify that your linker script accounts for the larger 28 KB Flash and 1 KB RAM available on this part.
コンプライアンス情報
RoHS and REACH compliant per Microchip product page. Industrial -I grade is not AEC-Q100 qualified; choose PIC16F1947T-E/PT for automotive applications requiring extended temperature range.
