Applications
The PIC16F1947-I/PT is designed for consumer appliances and industrial panel meters that require a microcontroller with an on-chip LCD driver to display readings such as temperature, flow rate, or energy consumption directly on a segmented glass display. Its 28 KB Flash and 256 B EEPROM store application code and calibration coefficients without external memory, while the 53 I/O pins in the TQFP-64 package connect to keypads, sensors, relays, and communication interfaces simultaneously. It is also used in smart metering and home energy monitoring products where 1.8 V operation extends battery life and the integrated peripherals reduce hardware complexity.

Frequently Asked Questions
What supply voltage range does the PIC16F1947-I/PT support, and can it run from a single alkaline battery?
The PIC16F1947-I/PT operates from 1.8 V to 5.5 V. A single AA alkaline cell discharges from approximately 1.7 V to 1.5 V during normal use, so the device can function directly from a single alkaline cell at reduced clock speeds, or from two AA cells covering the full 3 V range for higher-frequency 32 MHz operation in portable meter and remote sensor applications.
How many LCD segments can the PIC16F1947-I/PT drive directly, and which display types are compatible?
The PIC16F1947-I/PT integrates a dedicated LCD driver that supports up to 96 segments at 4 common lines, covering 4×24 or equivalent multiplex configurations used in standard 3.5-digit and 4-digit seven-segment glass displays. Backplane multiplex rates of 1/4 duty with 1/3 bias are natively supported, enabling direct connection to off-the-shelf segmented LCD modules without external driver ICs.
How much non-volatile storage does the PIC16F1947-I/PT provide, and is it sufficient for storing calibration data?
The PIC16F1947-I/PT provides 28 KB of Flash program memory and 256 bytes of data EEPROM. The 256-byte EEPROM is byte-erasable and rated for 100,000 write endurance cycles, making it well suited for storing calibration coefficients, user configuration parameters, and cumulative meter readings in energy monitoring or flow measurement applications without requiring an external serial EEPROM.
For industrial panel meter designs requiring many I/O lines, how does the PIC16F1947-I/PT compare with smaller PIC16 devices?
The PIC16F1947-I/PT in its TQFP-64 package exposes 53 general-purpose I/O pins, significantly more than the 24 pins of a 28-lead PIC16F device, allowing simultaneous connection to a 4×12 keypad, multiple sensor interfaces, relay drivers, and a UART for RS-485 communication without the need for I/O expander ICs. The 32 MHz clock with 8 MIPS throughput also handles display refresh, communications, and measurement tasks concurrently in a single-chip solution.
