Frequently Asked Questions
At what supply voltage can PIC16LF1946-I/PT operate at 16 MHz, and what does that mean for battery-powered designs?
The PIC16LF1946-I/PT operates at a minimum of 1.8 V when running at 16 MHz, which is low enough to run directly from two alkaline cells without a boost converter, significantly simplifying power-supply design and reducing BOM cost in portable devices.
How many I/O pins does the 64-pin TQFP package of PIC16LF1946-I/PT expose for peripheral connectivity?
The TQFP-64 package provides up to 53 general-purpose I/O pins, giving designers sufficient GPIO to interface with LCDs, keypads, sensors, and communication buses simultaneously in a 10 mm x 10 mm footprint without external I/O expanders.
When should a designer choose PIC16LF1946-I/PT over a 28-pin PIC16 device for an energy metering application?
When the application requires more than 28 I/O lines, multi-channel ADC inputs across 3 voltage phases, or a larger 14 KB Flash budget to accommodate calibration routines and communication protocol stacks, the 64-pin PIC16LF1946-I/PT is the appropriate upgrade path while staying within the familiar PIC16 development ecosystem.
What communication interfaces are available on PIC16LF1946-I/PT for connecting to external sensors?
The device integrates multiple UART, SPI, and I2C-compatible MSSP modules operating at up to 32 MHz system clock, enabling simultaneous communication with RS-485 transceivers, SPI-based displays, and I2C sensor ICs on a shared bus at standard 100 kHz and 400 kHz rates.
