PIC16F1718T-I/MV 概要
A PIC16F series microcontroller is an 8-bit Harvard-architecture MCU from Microchip's mid-range enhanced core family. The PIC16F1718 specifically targets cost-sensitive designs that require more than basic digital I/O, integrating Core Independent Peripherals (CLC, COG, NCO, Zero Cross Detect) and Peripheral Pin Select (PPS) for flexible pin mapping. This places it in the hierarchy: 8-bit MCU -> PIC16F1xx family -> mid-range enhanced core -> Microchip PIC16 product line -> Microcontrollers (IC category).
Key features include: 8-bit CPU core running up to 32MHz, 28KB self-programmable Flash, 2KB SRAM, 256 bytes EEPROM, 10-bit ADC with up to 17 channels, two on-chip operational amplifiers, an 8-bit DAC, two comparators, and PWM/SCCP/CCP timer modules. XLP technology delivers sleep currents as low as 20nA typical, enabling battery-powered applications. The MV package is a 28-pin UQFN (Ultra-thin Quad Flat No-lead, 4x4 mm) with an exposed thermal pad.
The PIC16F1718 uses a 14-bit instruction word and 8-bit data path with separate program and data buses (Harvard architecture). PPS allows digital peripheral pins to be remapped to any I/O, simplifying PCB routing. CLC (Configurable Logic Cell) lets designers create custom logic gates and timing functions in hardware without CPU intervention, while COG (Complementary Output Generator) provides programmable dead-band control for half-bridge drivers.
Typical applications include: LED lighting control (using COG and PWM), battery-powered sensor nodes (XLP sleep modes), home appliance user interfaces (CLC for capacitive touch or matrix scanning), small motor control (PWM + op-amps for current sensing), and IoT edge nodes. Designers benefit from the integrated op-amps and ADC for direct sensor signal conditioning without external analog ICs.
When designing with this part, note that the 28-UQFN package requires careful PCB thermal pad soldering and XLP current measurements require micro-ampere-capable lab equipment. The PPS feature needs MPLAB X IDE configuration before use, and Debug is supported only on the -ICD variant. Always check the latest Microchip datasheet errata for silicon revision-specific behavior.
This page synthesizes distributor pricing, pin-compatible alternatives within the PIC16F171x family, and practical design considerations not always immediately visible in the datasheet summary tables, helping engineers select the right 8-bit MCU for cost-sensitive embedded designs.

主な用途
PIC16F1718T-I/MV の用途: 6 件s: Battery-Powered IoT Sensor Node, LED Lighting and Backlight Control, Small Motor and Fan Control, Home Appliance User Interface, Industrial Sensor Transmitter, Capacitive Touch Interface.
Battery-Powered IoT Sensor Node
The PIC16F1718T-I/MV fits battery-powered IoT sensor nodes through its XLP technology delivering 20nA typical sleep current and integrated analog front end that eliminates external signal conditioning ICs. The 28KB Flash and 2KB SRAM comfortably support BLE/Zigbee stacks or LoRaWAN sensor drivers, while the 32MHz CPU (8 MIPS) handles periodic sensor reads, threshold decisions, and wake-up-driven RF transmission. The two on-chip op-amps directly interface with thermistor bridges or photodiode transimpedance circuits, with the 10-bit ADC (17 channels) multiplexing multiple sensors. Estimated: at 1 wake-up per minute with 10ms active time, average current draw falls below 5uA from a CR2032, enabling 5+ year battery life - critical for maintenance-free deployments in industrial monitoring.
おすすめ
LED Lighting and Backlight Control
The PIC16F1718T-I/MV drives LED lighting and backlight systems using its COG (Complementary Output Generator) for half-bridge driver timing, PWM modules for dimming, and CLC for hardware-based thermal foldback. The 8-bit DAC and op-amp combination provides closed-loop current regulation for high-brightness LED strings, while ZCD (Zero Cross Detect) supports TRIAC-dimmable AC mains LED retrofits. Compared to a discrete analog LED driver IC, the 1718 enables software-defined lighting profiles (CCT tuning, scene memory) without extra components. At 32MHz CPU speed, smooth 16-bit PWM dimming at 1kHz without visible flicker is achievable, and XLP sleep modes reduce standby power below 50uA in always-on smart-lighting fixtures.
おすすめ
Small Motor and Fan Control
The PIC16F1718T-I/MV controls small BLDC motors, fans, and pumps using its PWM/SCCP modules for commutation and the on-chip op-amps for current sensing via low-side shunt resistors. The COG peripheral generates complementary PWM outputs with programmable dead-band, essential for driving N-channel FET half-bridges without shoot-through. The 10-bit ADC samples back-EMF and current feedback at high rates, while the 32MHz core implements field-oriented control (FOC) loops for sinusoidal BLDC. Compared to dedicated motor-control ICs, the 1718 offers flexibility to add IoT connectivity (BLE/Wi-Fi co-processor) without redesigning the MCU. Estimated: at 10kHz PWM and 2ms control loop period, CPU utilization stays below 60% leaving headroom for user interfaces.
おすすめ
Home Appliance User Interface
The PIC16F1718T-I/MV powers home appliance user interfaces (washing machines, dishwashers, microwave ovens) by combining CLC-based matrix keypad scanning, PWM-driven buzzer/LED feedback, and 10-bit ADC for temperature/level sensor reads. The 28KB Flash supports graphical LCD or segment-display drivers, while XLP modes keep standby power below 30uA meeting Energy Star idle requirements. Peripheral Pin Select (PPS) enables flexible PCB routing when designing the same firmware for multiple product variants with different display configurations. Compared to a dedicated UI controller IC, the 1718 integrates a full 8-bit MCU plus analog and logic peripherals, reducing BOM cost by 30-40% in mid-range appliances.
おすすめ
Industrial Sensor Transmitter
The PIC16F1718T-I/MV serves 4-20mA industrial sensor transmitters and field instruments through its integrated op-amps for sensor signal conditioning, 10-bit ADC for digitizing process variables, and UART/SPI/I2C for digital protocol output (HART, IO-Link, Modbus). The wide 1.8V-5.5V operating range and -40C to +85C industrial temperature make it suitable for factory floor deployment. The 8-bit DAC can drive the 4-20mA loop directly via an external op-amp and pass transistor, with closed-loop accuracy dependent on Vref stability. According to Microchip datasheet DS40001775, the on-chip CLC and NCO support Manchester encoding for proprietary wireless sensor links, expanding flexibility beyond wired HART.
おすすめ
Capacitive Touch Interface
The PIC16F1718T-I/MV implements capacitive touch buttons and sliders using the on-chip CLC peripherals, comparators, and 10-bit ADC to perform charge-time measurement on capacitive sensors without external components. The 32MHz core processes mTouch algorithms (Microchip's capacitive touch library) in real time with sub-5ms response, supporting up to 17 touch channels. The PPS feature allows touch sensor pins to be remapped, simplifying PCB layout when product designers iterate on mechanical designs. Compared to dedicated touch ICs like the AT42QT1010, the 1718 combines touch sensing with a general-purpose MCU running application logic, reducing board space by approximately 30% in mixed-signal interfaces.

設計ノート
The 28-UQFN (MV) package has a center thermal pad (EP) that MUST be soldered to the PCB ground plane for mechanical reliability and thermal dissipation. Use a 0.4x0.4mm grid of 4x4 thermal vias to the inner ground plane. Keep signal traces away from the EP under the package to avoid solder wicking. The QFN pad pitch is 0.4mm, requiring PCB fabrication capability of 0.1mm trace/space or finer per IPC-6012 Class 3.
Place 100nF X7R decoupling capacitors as close as possible to each VDD pin pair. For the 32MHz HFINTOSC, add a 10uF bulk capacitor on the main VDD rail. XLP sleep current measurements must be made with all unused I/O pins configured as outputs low and no floating analog inputs - floating inputs can leak 1-10uA per pin. Use a guarded ammeter (Keithley SMU or equivalent) to verify 20nA sleep target. Estimated: at 3.3V VDD, 20nA sleep contributes 0.066uW quiescent power.
PPS (Peripheral Pin Select) must be configured in firmware before the corresponding peripheral is enabled; configuring PPS while a peripheral is active can cause glitches. When migrating from PIC16F886/887 (legacy), note that the 1718 has different default oscillator settings and requires explicit configuration of OSCCON and ACTCON. The MCLR pin (pin 27) cannot be disabled on this part; if your design needs MCLR as I/O, consider the PIC16F1713 or move to a different package option.
