What are the key features of PIC16LF1947-I/PT?
- 32MHz CPU with 28KB Flash and 2KB SRAM enabling complex firmware including state machines and protocol stacks in a single 8-bit device
- Integrated LCD segment driver eliminating external LCD controller ICs in cost-sensitive battery-powered meter and display designs
- 1.8V minimum supply operation extending usable battery discharge range in portable instruments powered by single Li-ion or two AA cells
- 12-bit ADC with up to 16 channels delivering high-resolution analog measurement for sensor and metering applications
What is PIC16LF1947-I/PT used for?
The PIC16LF1947-I/PT is engineered for portable battery-powered instruments such as digital multimeters, utility meters, and smart thermostats that need an integrated LCD driver alongside analog signal acquisition. Its 1.8V minimum supply allows the MCU to continue operating as a lithium coin cell or two-AA pack discharges below 2V, extending device service intervals. The 64-pin TQFP package provides ample GPIO for LCD segment control, keypad inputs, and serial communication interfaces without requiring external I/O expanders.

Frequently Asked Questions
Does the PIC16LF1947-I/PT include an on-chip LCD driver, and how many LCD segments can it control directly?
Yes, the PIC16LF1947-I/PT integrates an LCD module controller that can drive up to 96 LCD segments using internal COM and SEG multiplexing. This on-chip driver eliminates the need for a discrete LCD controller IC, reducing BOM cost by several dollars per unit and simplifying PCB routing in digital meter, scale, and smart-appliance display designs.
How does the PIC16LF1947-I/PT's 1.8V minimum supply benefit designs using two AA alkaline batteries?
Two AA alkaline batteries discharge from 3.0V to below 2.0V over their service life. The PIC16LF1947-I/PT operates reliably down to 1.8V at up to 16MHz, meaning it continues functioning when standard 2.7V-minimum devices would stop operating, extending product life by 20% to 30% and reducing the need for low-dropout boost converters that would add cost and complexity.
What ADC resolution and channel count does the PIC16LF1947-I/PT provide for multi-input sensor measurement?
The PIC16LF1947-I/PT includes a 12-bit SAR ADC with up to 16 multiplexed input channels. With a 2.048V reference, the 12-bit resolution provides 0.5mV per LSB resolution, sufficient for measuring thermocouple voltages, resistive sensor bridges, and 4–20mA current loop signals directly after simple signal conditioning, making it a cost-effective solution for multi-sensor industrial data loggers.
For a smart energy meter retrofit, how does the 64-pin TQFP package of the PIC16LF1947-I/PT help reduce external component count?
The 64-pin TQFP package exposes up to 49 GPIO lines alongside the LCD driver SEG/COM outputs, USART, SPI, and I2C peripherals — enough to control a 3.5-digit LCD display, a push-button keypad, an energy metering front-end IC via SPI, and an RS-485 communication transceiver all without adding port expanders. The 10mm x 10mm 0.5mm-pitch footprint fits in compact handheld enclosures while the peripheral integration reduces the PCB layer count from 4 to 2 in typical designs.
