PIC16F1718-E/SP Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and a fixed set of peripherals including timers, ADC, communication interfaces, and I/O ports. The PIC16F1718 belongs to the XLP (eXtreme Low Power) family of mid-range PIC microcontrollers and sits in the hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. It combines Intelligent Analog peripherals with XLP technology to serve general-purpose applications where both analog integration and battery-friendly operation are needed.
Key features include on-chip operational amplifiers, a 10-bit ADC with computation, 5-bit and 8-bit DACs, two CCP/PWM modules, Complementary Output Generator (COG), Numerically Controlled Oscillator (NCO), Zero Cross Detect (ZCD), Configurable Logic Cells (CLC), Peripheral Pin Select (PPS), EUSART, and I2C/SPI. The on-chip op amps and Core Independent Peripherals (CIPs) eliminate many external analog components and let state machines run without CPU intervention.
The architecture combines a RISC-style Harvard bus with a 49-instruction set, hardware multiplier, and direct interrupt-on-change I/O. Intelligent Analog integration (OPA, ADC with computation, DAC) and CIPs (CLC, COG, NCO, ZCD) reduce BOM count and firmware complexity, while PPS allows peripheral-to-pin remapping on the fly for flexible PCB layouts.
Typical applications include sensor signal conditioning, LED lighting control, low-power IoT edge nodes, motor control, battery chargers, and consumer appliances. The Extended temperature range makes it suitable for industrial and automotive under-hood environments.
When designing with this device, choose the correct configuration words for the internal oscillator (HFINTOSC up to 32MHz) and verify the PPS mapping against your pinout. Use the on-chip op amps with adequate compensation to prevent oscillation.

Typical Applications
PIC16F1718-E/SP is suitable for 7 applications: Industrial Sensor Signal Conditioning, Battery-Powered IoT Edge Nodes, LED Lighting Control Systems, Low-Voltage Motor Control, Smart Consumer Appliances, Automotive Under-Hood Modules, Test & Measurement Instrumentation.
Industrial Sensor Signal Conditioning
The PIC16F1718-E/SP is ideal for industrial sensor front-ends thanks to its two on-chip operational amplifiers and 10-bit ADC with computation. The op amps can directly buffer bridge-type sensors (load cells, pressure transducers) while the ADC2 automates averaging and threshold detection, offloading the CPU. The 32MHz core processes 8 MIPS, sufficient for linearization, calibration, and HART-style digital modulation in 4-20mA loops. Industrial 24V rails are easily scaled via resistor dividers into the 5.5V-tolerant I/O, and the -E extended temperature grade handles factory floor environments up to +125C.
Recommended
Battery-Powered IoT Edge Nodes
The PIC16F1718-E/SP suits coin-cell IoT sensor nodes through its XLP technology: deep sleep current in the nanoamp range, peripheral module disable, and Core Independent Peripherals (CLC, NCO, ZCD) that operate while the CPU is asleep. The 1.8V minimum VDD supports single CR2032 or 2x AA operation without boost converters. The on-chip op amps directly interface thermistors, photocells, and electrochemical sensors, while the 28KB Flash accommodates OTA bootloader and application code. PPS allows flexible I/O mapping so the same PCB supports multiple sensor variants.
Recommended
LED Lighting Control Systems
The PIC16F1718-E/SP drives multi-channel LED lighting via its two CCP/PWM modules plus the Complementary Output Generator (COG) for half-bridge LED drivers. The 10-bit ADC reads ambient light sensors for closed-loop dimming, and the on-chip op amps condition thermistor inputs for thermal foldback protection. The 5-bit and 8-bit DACs generate reference voltages for current control loops. With 32MHz operation, color-mixing algorithms and DMX-512-style communication run in real time, and the Extended temperature grade ensures reliability in enclosed luminaire housings.
Recommended
Low-Voltage Motor Control
The PIC16F1718-E/SP handles small DC and stepper motor control through its CCP/PWM peripherals, COG for complementary drive, and QEI (Quadrature Encoder Interface) for position feedback. The on-chip op amps amplify Hall sensor or shunt-current signals directly, while the ADC2 performs zero-crossing and overcurrent detection in hardware. The NCO can generate high-resolution PWM frequencies independent of the main clock, useful for ultrasonic or resonant drive topologies. With 28KB Flash and 2KB RAM, space vector or trapezoidal commutation routines fit comfortably.
Recommended
Smart Consumer Appliances
White-goods and small kitchen appliances benefit from the PIC16F1718-E/SP combination of touch sensing (via on-chip op amps), ADC, and PWM control for motor and heater regulation. The CLC (Configurable Logic Cells) implement glue logic such as interlocks and timing supervision without external gates, while the ZCD detects AC line zero crossings for TRIAC dimming. EUSART and I2C/SPI connect to user-interface displays and BLE/Wi-Fi companion modules. The Extended temperature grade supports oven-adjacent and dishwasher-integrated electronics up to +125C.
Recommended
Automotive Under-Hood Modules
The -E extended temperature grade (-40C to +125C) of the PIC16F1718-E/SP suits automotive under-hood modules such as sensor clusters, fan controllers, and lighting drivers. The on-chip op amps condition 12V-scaled sensor inputs, while the ADC2 performs windowed conversions for crank/cam position sensing. The COG generates complementary PWM for solenoid and injector drive, and the EUSART interfaces with LIN or CAN transceivers. 28KB Flash holds AUTOSAR-lite or OEM-proprietary firmware with bootloader for service reprogramming.
Recommended
Test & Measurement Instrumentation
The PIC16F1718-E/SP is suitable as a control MCU in low-cost handheld test equipment: multimeters, insulation testers, and process calibrators. The 10-bit ADC with computation performs RMS and averaging on scaled measurement inputs, while the on-chip op amps provide high-impedance buffering. The 32MHz core drives OLED or LCD character displays via SPI, and the CLC implements custom timing logic. With 28KB Flash, complex calibration tables and IEEE-754 math libraries fit, and the Extended temperature range supports outdoor field use.

Key Differentiators
- Higher Flash and RAM with same Intelligent Analog integration (vs PIC16F1713-I/SP)
- Extended temperature grade (-E) for harsh-environment reliability (vs PIC16F1718-I/SP)
- Combined COG + CLC + NCO + ZCD in a 28-pin device (vs PIC16F1618-E/SS)
- Through-hole SPDIP-28 for prototyping and field-serviceable designs (vs PIC16F1618-E/SS)
Design Notes
Estimated: At 32MHz operation and 5.5V VDD, the PIC16F1718-E/SP core draws approximately 8mA; at 3.3V VDD and 4MHz, this drops to about 1.5mA. In sleep mode with WDT disabled, the XLP technology delivers less than 50nA. Use a 10uF bulk + 0.1uF decoupling pair within 5mm of the VDD pin, and place a 10kohm pull-up on MCLR for clean reset behavior.
Route the analog AVdd and AVss separately from digital VDD/VSS using star-ground topology to minimize ADC noise coupling. Keep analog traces short and away from PWM outputs and clock lines. The 28-SPDIP package has no dedicated AVdd pin, so isolate analog supply via ferrite beads from the digital rail.
When migrating PIC16F1718-E/SP code from PIC16F1826/1827, the PPS (Peripheral Pin Select) feature requires re-mapping peripheral outputs to physical pins using the PPSLOCK register sequence. Failure to unlock PPS before configuration leaves peripherals mapped to default pins and may cause unexpected behavior. Refer to section 12 of the family datasheet for the unlock/lock sequence.
The 28-SPDIP package has typical theta_JA around 70-80 C/W in still air. At maximum +125C ambient and full 32MHz operation, verify junction temperature stays below the +150C maximum using the device power consumption vs frequency curves in the datasheet. Industrial applications with restricted airflow may need to derate Fosc.
Compliance Information
RoHS and REACH compliant per Microchip product page. The -E extended temperature grade supports industrial use; AEC-Q100 automotive qualification requires selecting an AEC-qualified part number, not the PIC16F1718-E/SP.
