The PIC16F1946-I/PT is a feature-rich 8-bit microcontroller from Microchip’s enhanced mid-range PIC16F family, distinguished by its integrated LCD controller capable of driving up to 184 segments directly. This eliminates the need for an external LCD driver IC, reducing BOM cost and board space in display-intensive applications. The device offers 14KB Flash program memory, 512 bytes of RAM, and 256 bytes of data EEPROM, along with 54 I/O pins. Peripheral integration includes a 17-channel 10-bit ADC, mTouch capacitive sensing, dual EUSART (with LIN support), dual MSSP for SPI/I2C, three comparators, and five PWM channels. The 64-pin TQFP package provides sufficient I/O for both the LCD segment outputs and general-purpose interfacing.

The PIC16F1946 uses Microchip’s enhanced mid-range architecture with 49 instructions and a 16-level hardware stack. The LCD controller generates the multiplexed drive waveforms for segment-type LCDs, supporting static, 1/2, 1/3, and 1/4 multiplex modes with up to 48 commons × 184 segments. The LCD timing operates independently from the CPU, with its own interrupt. The mTouch capacitive sensing module uses a charge-time measurement unit (CTMU) or ADC-based technique to detect finger touch on the same pins used for other functions. Peripheral Pin Select (PPS) allows remapping of digital peripheral functions to different I/O pins for PCB layout optimization. The nanoWatt XLP technology enables Sleep mode with LCD operation (LCD module can run while CPU sleeps), drawing only microamps.

  • Smart Meter with LCD: Build a single-chip electricity meter using the LCD controller to drive a 4-mux segment display showing kWh, voltage, and current. The 17-channel ADC reads current and voltage sensors. Dual EUSART provides data communication to the metering network. The LCD controller runs in Sleep mode to minimize power consumption while maintaining the display.
  • Thermostat Controller: Use the LCD controller to drive a custom segment display showing temperature, set-point, and HVAC mode. The mTouch module implements capacitive touch buttons for user interface without mechanical switches. The dual MSSP interfaces communicate with a temperature sensor (I2C) and an RF module (SPI). PWM outputs control fan speed.
  • Industrial Panel Meter: Drive a 1/3-mux LCD showing process variables. The 54 I/O pins allow simultaneous LCD drive and multi-channel analog input scanning. The 1.8V minimum supply enables low-power operation from a 2-cell alkaline battery, while the LCD module continues displaying readings even when the CPU sleeps between measurement cycles.
