PIC16LF1517T-I/PT Présentation
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, digital I/O, and on-chip peripherals such as ADCs, timers and communication interfaces. Within the semiconductor hierarchy, MCUs sit between discrete logic and full microprocessors (MPUs), trading raw performance for integration, low power, and deterministic real-time behaviour in cost-sensitive embedded systems.
Key features include the PIC16 enhanced mid-range core with 200 ns instruction execution, 14 KB self-programmable Flash, 512 B SRAM, two 8-bit timers and one 16-bit timer, two CCP modules, an EUSART, MSSP (SPI/I²C), 10-bit ADC with up to 28 channels, an internal oscillator, and the PIC XLP™ ultra-low-power architecture with nanoWatt Sleep. These traits make the part well suited to battery-powered sensor nodes and industrial peripherals.
Architecturally the device uses a Harvard RISC pipeline with a 14-bit instruction word, allowing compact code density and predictable interrupt latency. The internal 16 MHz HF oscillator can be tuned, eliminating the need for an external crystal in many designs and reducing BOM cost.
Typical applications include IoT sensor nodes, industrial control, battery-powered instrumentation, motor drive signal conditioning, low-power wireless sensor hubs, and consumer appliances. The wide ADC channel count also supports multi-signal data acquisition front-ends.
When laying out a board, ensure adequate decoupling (100 nF + 1 µF) near VDD/AVDD pins and route the ICSP/ICD programming lines (PGC/PGD) with short, direct traces. The internal oscillator is adequate for most UART and PWM tasks, but designs requiring tight timing accuracy should enable the secondary crystal driver.

Applications typiques
PIC16LF1517T-I/PT convient pour 6 applications: Battery-Powered IoT Sensor Node, Industrial Control & Human-Machine Interface (HMI), Consumer Appliance Control Board, Motor Drive Signal Conditioning, Low-Power Wireless Sensor Hub, Data-Acquisition Front-End.
Battery-Powered IoT Sensor Node
The PIC16LF1517T-I/PT's 1.8 V to 3.6 V VDD and PIC XLP™ nanoWatt Sleep current make it ideal for battery-powered wireless sensor nodes. With 14 KB of Flash and 512 B of SRAM, the MCU comfortably runs a state-machine plus a UART- or SPI-based radio driver such as a sub-GHz or BLE companion chip. The 10-bit ADC enables direct interface to analog sensors like temperature, gas or strain gauges without external signal conditioning.
Recommandé
Industrial Control & Human-Machine Interface (HMI)
In industrial control panels the PIC16LF1517T-I/PT drives keypads, LED indicators and small character LCDs using its 36 I/O pins and EUSART. The 44-TQFP package allows direct mounting behind a panel with plenty of I/O for buttons and status LEDs. Designers can use the two CCP modules for PWM backlight control and 10-bit ADC channels for sensing operator inputs such as potentiometers or thermistors.
Recommandé
Consumer Appliance Control Board
White goods and small kitchen appliances benefit from the PIC16LF1517T-I/PT's small footprint, internal oscillator and 36 I/O. The device can directly drive TRIAC gates, sense line voltage zero-crossing, and read NTC thermistors for closed-loop temperature regulation. 14 KB of Flash is plenty for application code, while nanoWatt Sleep keeps standby power below regulatory limits such as Energy Star.
Recommandé
Motor Drive Signal Conditioning
The PIC16LF1517T-I/PT fits motor-control front-end tasks such as Hall-sensor decoding, current sensing and PWM generation for small DC or stepper motor drivers. Two CCP modules generate complementary PWMs with dead-band control for half-bridge FET drivers. The 10-bit ADC samples motor current via a shunt amplifier at the rate needed for basic torque loops.
Recommandé
Low-Power Wireless Sensor Hub
The PIC16LF1517T-I/PT functions as a low-power protocol bridge between sensors and a host radio (LoRa, BLE or sub-GHz). The EUSART and MSSP peripherals drive the radio transparently while nanoWatt Sleep keeps idle current in the microamp range. With 512 B of SRAM the device buffers small sensor frames before transmitting, and 14 KB of Flash hosts a full portable state machine.
Recommandé
Data-Acquisition Front-End
With multiple 10-bit ADC channels, the PIC16LF1517T-I/PT serves as a low-cost multi-channel data-acquisition front-end for instrumentation and laboratory equipment. I²C/SPI peripherals connect to external 16- or 24-bit ADCs while the MCU manages averaging, calibration and host communication via EUSART USB-to-UART bridges. Industrial temperature grade and 44-TQFP simplify PCB layout for multi-board stacks.

Principaux différenciateurs
- Larger 44-TQFP package with maximum I/O in the family (vs PIC16LF1516T-I/SO)
- 14 KB Flash vs smaller variants (vs PIC16LF1507-I/SS)
- Lower operating voltage floor than F-variant (vs PIC16F1517T-I/PT)
Notes de conception
Estimated: at 20 MHz and 3.3 V VDD, typical IDD is roughly 5-7 mA per the PIC16 enhanced-mid-range datasheet. Decouple VDD/VSS with a 100 nF ceramic placed within 5 mm of the supply pins, and place a 10 µF bulk capacitor on the board supply rail. Enable nanoWatt Sleep whenever the CPU is idle for >1 ms to drop quiescent current below 1 µA. The PIC16LF1517T-I/PT's 1.8 V minimum VDD allows direct battery operation from two alkaline cells.
Route the ICSP signals (PGC on RB6/ICSPCLK and PGD on RB7/ICSPDAT) with short traces and avoid passing them under switching signals or oscillators. Provide a 4-pin 0.1" header (or test pads) on the board for the PICkit / MPLAB Snap programmer. For QFP packages keep ground stitching vias as close to the exposed thermal pad (if present) as possible and flood the top layer with a ground pour under the chip.
Do not confuse the PIC16LF1517 (1.8-3.6 V) with the PIC16F1517 (2.3-5.5 V). The LF device will brown-out at 5 V rails. Ensure MCLR has a proper RC rise-time (10 kΩ pull-up, 100 nF to VDD) unless disabled in configuration bits. When using the internal oscillator at 16 MHz allow at least 4 ms startup delay before code execution to ensure stable clock.
