PIC16LF1517-E/PT Présentation
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, timers, communication peripherals, and I/O on a single IC. The PIC16F family is positioned in Microchip's mid-range 8-bit hierarchy above the PIC10/12/14 baseline parts and below the PIC18 extended-instruction family, and the LF variant denotes the 1.8V-3.6V low-voltage process. XLP technology adds deep-sleep currents down to the nanoampere range, supporting battery-powered applications such as IoT sensors, portable instruments, and remote controls.
Key features include 35 digital I/O pins, an on-chip 32 kHz oscillator for low-power RTC operation, an enhanced watchdog timer, and brown-out reset (BOR). The 10-bit ADC provides up to 28 analog channels with conversion rates suitable for sensor signal acquisition. Two CCP modules enable motor control, LED dimming, and PWM-driven actuator outputs. The device supports in-circuit serial programming (ICSP) via MPLAB X IDE and is compatible with the MPLAB Snap, PICkit 4, and ICD 4 debuggers.
Architecturally, the PIC16LF1517 employs a modified Harvard RISC core with 49 instruction types, a single-cycle instruction decoder, and interrupt-driven event handling. The 20 MHz oscillator yields 5 MIPS peak throughput, while XLP sleep currents as low as 30 nA (typical, with RTC running) enable multi-year coin-cell battery operation. The 44-TQFP package provides generous I/O count and is footprint-compatible with PIC16F1517 family variants, simplifying PCB reuse across voltage ranges.
Typical applications include industrial sensor nodes, home automation controllers, battery-powered IoT edge devices, consumer electronics with HMI interfaces, and low-cost motor control. Its wide 1.8V-3.6V supply range and low quiescent current also suit energy-harvesting designs, remote keyless entry, and metering products. Designers should pair the device with a low-Iq LDO and follow Microchip's AN 1416 layout guidelines for optimal EMI performance. For cost-optimized platforms without the enable pin or larger Flash, the PIC16LF1516 and PIC16LF1513 are pin-compatible siblings.

Applications typiques
PIC16LF1517-E/PT convient pour 6 applications: Battery-Powered IoT Sensor Nodes, Industrial Sensor Hubs and PLC I/O, Home Automation and HMI Controllers, Low-Cost BLDC and DC Motor Control, Consumer Remote Controls and Key Fobs, Smart Metering and Energy Monitoring.
Battery-Powered IoT Sensor Nodes
The PIC16LF1517-E/PT is well suited for battery-powered IoT sensor nodes because its XLP architecture delivers sleep currents below 30 nA (typical) with the 32 kHz RTC running, while the 1.8V-3.6V VDD range supports 2x AA alkaline or single-cell Li-ion chemistries directly without boost conversion. The 14 KB Flash accommodates trimmed MQTT-SN, BLE HCI, or LoRaWAN MAC stacks, and the 10-bit ADC with up to 28 channels digitizes temperature, humidity, and gas-sensor outputs. Two CCP modules drive PWM-actuated relays or LED indicators, while the integrated EUSART with LIN support provides a robust wired backhaul option for industrial sensor hubs.
Recommandé
Industrial Sensor Hubs and PLC I/O
In industrial sensor hub and PLC remote-IO applications, the PIC16LF1517-E/PT offers -40C to +125C extended operating temperature, EUSART with LIN 2.1 master support, and 35 digital I/O pins that map directly to industrial sensor arrays. The MSSP peripheral provides SPI for fast ADC/DAC communication and I2C for slow sensor polling, while the 10-bit ADC at 28 channels supports 4-20 mA current-loop sensing through external burden resistors. The 20 MHz CPU executes deterministic 5-MIPS control loops for PID-based process control with sub-millisecond response, and the brown-out reset protects against industrial supply brownouts.
Recommandé
Home Automation and HMI Controllers
For home automation controllers, the PIC16LF1517-E/PT delivers the I/O count and peripheral mix needed for keypad, LCD, and triac-driver interface. The 14 KB Flash fits compact Z-Wave/Zigbee application profiles, and two CCP modules generate the zero-crossing delays required for phase-controlled dimmer circuits. The EUSART links to a host radio module over a UART interface, while the MSSP drives an SPI-based TFT LCD for local HMI feedback. The 1.8V-3.6V range simplifies USB or 5V wall-adapter powered designs with a single low-Iq LDO, reducing BOM cost in volume home-automation products.
Recommandé
Low-Cost BLDC and DC Motor Control
The PIC16LF1517-E/PT targets low-cost brushed DC and small BLDC motor control applications where the two CCP modules generate complementary PWM signals with programmable dead-band via the enhanced PWM mode. The 10-bit ADC samples back-EMF or shunt-current feedback at sufficient rates for inner-loop current control, while the 20 MHz CPU executes field-oriented control (FOC) variants at reduced switching frequencies for small pumps and fans. With 35 I/O pins, designers can integrate Hall-sensor inputs, fault comparators, and brake-coil drivers without external logic, shrinking the BOM in appliance motor boards.
Recommandé
Consumer Remote Controls and Key Fobs
The PIC16LF1517-E/PT powers remote controls and keyless-entry key fobs by combining nanoamp sleep currents, sufficient Flash for rolling-code security algorithms, and a low-power 32 kHz oscillator that keeps an internal RTC alive for months on a CR2032 coin cell. The EUSART or MSSP drives sub-GHz or BLE companion modules, while the 10-bit ADC reads battery voltage and capacitive touch inputs for button-less interfaces. The -40C to +125C rating ensures reliable operation in vehicle cabins and outdoor enclosures across automotive and consumer remote-control segments.
Recommandé
Smart Metering and Energy Monitoring
The PIC16LF1517-E/PT fits single-phase energy metering sub-systems where the 10-bit ADC digitizes voltage and current sense outputs, and the 14 KB Flash implements IEC 62053-21 calibration tables and tamper detection logic. The MSSP communicates with an isolated metrology front-end or external EEPROM for billing data, while the EUSART provides a wired M-Bus or wireless link to concentrators. XLP sleep currents below 50 nA extend battery life in disconnect-relay applications, and the 1.8V minimum VDD supports direct operation from lithium-thionyl chloride primary cells in non-interruptible gas and water meters.

Notes de conception
Estimated: At 20 MHz active and VDD = 3.3 V, the PIC16LF1517-E/PT consumes approximately 2 mA typical core current. For battery-powered designs, place the device in Sleep mode between sensor reads to achieve 30 nA typical standby with the 32 kHz oscillator running. Tie MCLR high through a 10 kohm resistor to VDD and add a 100 nF decoupling capacitor at the MCLR pin to prevent spurious resets. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the pin.
Route the ICSP clock and data lines (ICSPCLK on RA1 and ICSPDAT on RA0) with short, parallel traces kept away from switching signals such as PWM outputs and oscillator traces. Add a 4.7 kohm pull-up resistor to VDD on MCLR to prevent in-circuit programming from inadvertently resetting the device. Keep the analog AVdd/AVss pair (or the shared VDD/VSS if no separate analog pins exist) routed with a wide ground return and place the 100 nF analog decoupling capacitor adjacent to the analog reference pin (RA3/VREF+ when used).
Do not assume the 44-TQFP and 40-PDIP packages of the PIC16LF1517 family share identical pin functions; the 44-pin device has additional analog channels on RE0-RE2 and extra Port C pins on pins 41-44 that are NC on the 40-pin package. Always re-validate the .INC file against the chosen package symbol in MPLAB X before committing to a PCB layout. When migrating between LF (1.8-3.6V) and F (2.3-5.5V) variants, ensure the LDO output voltage stays within the chosen variant's VDD range, especially during low-battery cut-off.
