PIC16F1517-E/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one silicon die. PIC16F1xxx-series devices are mid-range 8-bit MCUs that sit inside the broader hierarchy: microcontroller -> embedded processor -> semiconductor IC. The "XLP" suffix denotes Microchip's nanoWatt eXtreme Low-Power technology, which minimizes active and sleep current consumption for battery-powered and energy-harvesting designs. The 8-bit core remains dominant in cost-sensitive, deterministic, low-power embedded applications where 32-bit performance is unnecessary.
Key features include an internal 16MHz oscillator, two CCP (Capture/Compare/PWM) modules, a Master I²C (MI2C) peripheral, SPI, and EUSART with autobaud. The device also integrates 28 channels of 10-bit ADC with voltage reference, two 8-bit timers, and 25mA source/sink capable I/O pins. High-endurance data Flash (100,000 W/E cycles) is provided in the lower 128 bytes of program memory for non-volatile parameter storage.
Architecture-wise, the PIC16F1517 uses a Harvard-architecture enhanced mid-range core with separate program Flash and data SRAM buses, allowing simultaneous instruction fetch and data access. The 14-bit instruction word balances code density against execution speed. Integrated peripherals are mapped to pin-function multiplexers, simplifying PCB routing while retaining flexibility.
Typical applications include industrial control modules, sensor signal conditioning, low-power IoT edge nodes, white goods and appliance controls, and battery-backed instrumentation. The wide 1.8V-5.5V supply range and XLP nanoWatt sleep modes make it suitable for energy-harvesting and portable products.
When designing with the PIC16F1517-E/PT, ensure the ICSP™ programming pins (PGx, PGCx) are routed to accessible test points for in-circuit programming. The internal 16MHz oscillator can be trimmed via the OSCTUNE register, but for UART or USB timing-critical applications a crystal is recommended for stability.

Typical Applications
PIC16F1517-E/PT is suitable for 6 applications: Industrial Sensor Signal Conditioning, Battery-Powered IoT Edge Node, Home Appliance Control Board, Automotive Body and Lighting Module, Portable Medical Monitoring Device, Consumer Electronics User Interface.
Industrial Sensor Signal Conditioning
The PIC16F1517-E/PT is well suited for industrial sensor conditioning hubs where multi-channel analog inputs require on-chip digitization. Its 28-channel 10-bit ADC eliminates an external ADC ASIC, while the 20 MHz enhanced mid-range core handles linearization and digital filtering in real time. The 36 I/O pins interface directly to 4-20 mA loop drivers, relay outputs, and opto-isolated digital buses, and the -40°C to +125°C extended temperature range supports factory-floor enclosures. With 14KB Flash and 512B RAM, the MCU can run a TCP/IP-to-RTU gateway stack or Modbus slave firmware locally without an external host processor.
Recommended
Battery-Powered IoT Edge Node
Low-power wireless IoT endpoints benefit from the PIC16F1517-E/PT's nanoWatt XLP sleep modes and 1.8V-5.5V supply range. In a typical LoRa or Sub-GHz edge node, the MCU spends 99% of its life in sleep, waking only to digitize sensors and transmit. The integrated 10-bit ADC with 28 channels reads temperature, humidity, and battery voltage without external ADCs. The EUSART autobaud feature supports direct connection to a Sub-GHz transceiver such as the Microchip MRF89XA, while the two CCP PWM modules can drive indicator LEDs or buzzer alarms on threshold events.
Recommended
Home Appliance Control Board
White-goods appliance control boards (washing machines, dishwashers, microwave ovens) require a robust MCU that survives motor noise, relay switching transients, and wide temperature swings. The PIC16F1517-E/PT's extended -40°C to +125°C range and 25 mA source/sink capable I/O directly drive TRIAC gates and relay coils without external drivers. The two CCP modules generate zero-crossing-switched PWM for AC load dimming, while the MI2C and SPI interfaces connect to user-interface keypads, segment LCDs, and rotary encoders. The 14KB Flash comfortably fits typical appliance firmware with state-machine motor control.
Recommended
Automotive Body and Lighting Module
Although the PIC16F1517-E/PT itself is not AEC-Q100 qualified, its extended temperature grade and feature set make it a candidate for non-safety automotive body electronics such as interior lighting, HVAC actuators, and instrument-cluster sub-modules. The 36 I/O and 28 ADC channels handle multiple LED strings via PWM dimming, thermistor inputs, and rotary-knob encoders. The EUSART autobaud connects to a body-controller CAN bridge, while the nanoWatt XLP mode supports parasitic-sleep current budgets on parked-vehicle modules. For safety-critical ECUs, Microchip recommends PIC18- or dsPIC33-qualified variants instead.
Recommended
Portable Medical Monitoring Device
Battery-powered patient monitors benefit from the PIC16F1517-E/PT's combination of low sleep current and analog integration. The 28-channel 10-bit ADC reads multiple bioelectric signals (temperature, SpO2 photodiode, battery state) simultaneously, while the 20 MHz core performs digital filtering and trend storage. The 14KB Flash supports a small RTOS-style scheduler and BLE/HID driver. The -40°C to +125°C operating range covers clinical-environment temperature swings, and the TQFP-44 footprint enables compact handheld device PCBs with RF shielding cans still routable.
Recommended
Consumer Electronics User Interface
The PIC16F1517-E/PT provides cost-effective user-interface control for consumer devices such as remote controls, smart thermostats, and small kitchen appliances. Its MI2C and SPI interfaces connect to capacitive touch controllers, OLED displays, and audio DACs, while the two CCP modules drive backlight PWM and haptic-feedback motors. The 20 MHz core handles USB HID via bit-banged or soft-stack implementations on the EUSART, and the 14KB Flash accommodates multi-language UI strings. With 36 I/O the MCU reads dozens of buttons and rotary controls directly without a key-scan expander.

Key Differentiators
- Highest program-memory density within PIC16F151x series (vs PIC16F1516-I/SO)
- Extended -40°C to +125°C operating temperature range (E grade) (vs PIC16F1517-I/PT)
- 36 I/O pins with 25 mA source/sink (vs PIC16F1513-I/SS)
Design Notes
The PIC16F1517-E/PT integrates dual VDD/VSS pin pairs (pins 5/4, 20/19, 42/41). Connect all VDD pins to the same 1.8V-5.5V rail and all VSS pins to the ground plane directly, with a 100nF decoupling capacitor placed within 5mm of each VDD/VSS pair. Adding a bulk 10uF tantalum or ceramic capacitor near the MCU reduces transient droop during CCP PWM-driven load switching. For battery applications, the nanoWatt XLP mode reduces sleep current to ~50 nA typical; refer to the datasheet DC characteristics section for exact figures at your operating temperature.
Route the crystal traces (OSC1/OSC2, pins 43/44) as short as possible and guard them with a ground pour to minimize stray capacitance. Keep the ICSP programming pins (RB6/RB7 = ICSPCLK/ICSPDAT) accessible on test points or a 6-pin header so the device can be re-flashed in-circuit using the MPLAB Snap or PICkit 4. If the design uses the internal 16 MHz oscillator exclusively, leave OSC1/OSC2 as no-connect or route them to a footprint for an optional crystal.
Do not exceed 5.5 V on any pin; the PIC16F1517-E/PT is NOT 5V-tolerant on analog/digital I/O above 5.5V. The MCLR pin (RA3/RE3) requires a 10 kΩ pull-up to VDD; floating MCLR prevents the device from starting. Watchdog Timer (WDT) is enabled by default in the configuration bits; explicitly disable WDT in software unless needed, or your firmware may reset unexpectedly. ADC reference voltage (VREF+ / VREF-) must be tied to known rails; floating VREF- causes erratic ADC readings.
Although the PIC16F1517-E/PT draws low current, the TQFP-44 package has a thermal resistance (θJA) of approximately 50°C/W on a 2-layer JEDEC test PCB. For designs operating continuously at 20 MHz across the +125°C upper limit, ensure at least 100 mm² of uninterrupted copper pour on the top layer tied to VSS to keep junction temperature below 150°C and preserve long-term reliability.
Compliance Information
RoHS and REACH compliance per Microchip product page. Not AEC-Q100 qualified; for safety-critical automotive ECUs use PIC18K- or dsPIC33-grade parts. The E temp grade (-40°C to +125°C) extends beyond standard industrial but does not constitute AEC-Q100 qualification.
