PIC16F1718-I/SS 概要
An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip built around an 8-bit data path. It typically integrates a CPU, Flash program memory, RAM, EEPROM, and a rich set of peripherals (ADC, timers, communication interfaces, and increasingly analog blocks) into a single IC. MCUs sit under the broader hierarchy: microcontroller → embedded controller → semiconductor, and serve as the decision-making core in everything from consumer appliances to industrial sensor nodes.
Key features include a 32MHz internal oscillator (8MHz with 4x PLL), four 16-bit timers, enhanced PWM modules, EUSART, I²C/SPI interfaces, and the XLP extreme-low-power technology that delivers nanoWatt sleep currents suitable for battery-powered applications. The 28-SSOP package is industry-standard, hand-solderable, and reflow-compatible on 2-layer boards.
The PIC16F1718's Intelligent Analog integration is the standout architectural choice: rather than requiring external op-amps for sensor signal chains, designers can use the internal op-amps as buffers, gain stages, or comparators, reducing BOM cost and PCB area. PPS further increases routing flexibility in tight 28-pin layouts where dedicated peripheral pin assignments would otherwise force awkward signal routing.
Typical applications include battery-powered sensor nodes, HVAC thermostat controls, consumer white goods, low-cost IoT endpoints, LED lighting controllers, and analog signal conditioning front-ends. The wide operating voltage range (1.8V–5.5V) suits both 3.3V and 5V rails.
When designing with this device, place the decoupling 100nF capacitor within 5mm of VDD, use PPS carefully to avoid peripheral conflicts, and leverage the on-chip op-amps to minimize external analog components for lowest total system cost.

主な用途
PIC16F1718-I/SS の用途: 6 件s: Battery-Powered Sensor Nodes, HVAC Thermostat Control, Consumer White Goods, LED Lighting Controllers, IoT Edge Sensor Conditioning, Analog Signal Conditioning Front-Ends.
Battery-Powered Sensor Nodes
The PIC16F1718-I/SS is ideal for battery-powered wireless sensor nodes thanks to its XLP (eXtreme Low Power) architecture and 1.8V-5.5V operating range. With the internal 32MHz oscillator gated off in Sleep, the MCU consumes nanoWatt-level standby current, allowing coin-cell-powered nodes to last years. The on-chip 10-bit ADCC samples sensors autonomously without waking the CPU, while the integrated op-amp conditions the analog signal before conversion. Peripheral Pin Select (PPS) lets designers remap EUSART/SPI to any RP pin, simplifying PCB routing around an antenna keep-out. The 28KB Flash comfortably fits a Zigbee/BLE stack plus application logic.
おすすめ
HVAC Thermostat Control
In HVAC thermostat designs, the PIC16F1718-I/SS serves as the central control MCU, leveraging its two on-chip op-amps to condition thermistor or RTD temperature signals without external analog ICs. The Zero Cross Detect (ZCD) peripheral detects AC line zero-crossings for synchronous triac triggering of HVAC loads, while the Complementary Output Generator (COG) produces the dead-time-controlled PWM for solid-state relay drive. The CLC can implement safety interlocks entirely in hardware, freeing the CPU for PID control loops. The 28KB Flash supports both the user interface state machine and the PID auto-tuning firmware.
おすすめ
Consumer White Goods
The PIC16F1718-I/SS fits consumer white goods (washing machines, dishwashers, ovens) as a cost-optimized control MCU with 28KB of Flash for user interface, motor control, and safety logic. The Enhanced PWM module drives brushless DC or universal motors directly, while the EUSART interfaces to the HMI display board. The industrial -40 to +85°C temperature range handles the under-cabinet thermal environment. The 5x5mm 28-SSOP package is reflow-compatible with standard lead-free processes, keeping manufacturing cost low for high-volume consumer production.
おすすめ
LED Lighting Controllers
The PIC16F1718-I/SS drives constant-current LED drivers in smart lighting applications, using the on-chip op-amps as transconductance amplifiers for current feedback. The 16-bit PWM provides high-resolution dimming below 1% duty cycle, while the CLC implements dithering or color-mixing logic in hardware. The Numerically Controlled Oscillator (NCO) generates accurate DALI or 0-10V dimming frequencies. The Peripheral Pin Select feature lets PCB designers place PWM outputs adjacent to the LED driver FETs, minimizing switching-node trace inductance and EMI.
おすすめ
IoT Edge Sensor Conditioning
In IoT edge devices, the PIC16F1718-I/SS performs local analog signal conditioning before the data is forwarded upstream via BLE, LoRa, or Wi-Fi. The integrated 10-bit ADCC with oversampling provides up to 12-bit effective resolution for sensor measurements, while the two on-chip op-amps implement low-noise instrumentation or transimpedance amplification for photodiodes. The CLC (Configurable Logic Cell) creates custom glue logic without external gates, reducing BOM cost. XLP sleep currents below 1µA make this MCU ideal for energy-harvesting edge nodes.
おすすめ
Analog Signal Conditioning Front-Ends
The PIC16F1718-I/SS functions as a low-cost analog front-end for industrial sensors, replacing discrete op-amp + ADC + MCU designs. The on-chip op-amps provide gain stages for strain gauges, load cells, or pressure transducers, while the integrated 10-bit ADCC performs oversampled conversion for higher effective resolution. The DAC modules (5/8-bit) generate calibration or excitation signals. Peripheral Pin Select allows the EUSART/I²C to share pins with the analog channels, maximizing the 28-SSOP pin budget for sensor interfaces in compact industrial modules.

設計ノート
Decouple VDD with a 100nF X7R ceramic capacitor placed within 5mm of the MCU's VDD pin (pin 1 and pin 20 are both VDD on the 28-SSOP; both must be decoupled). For designs that switch the -LF or -F variant's internal op-amps actively, add a 10µF bulk capacitor near the analog VDD pin pair to suppress load-transient dips. The PIC16F1718's XLP Sleep current is below 100 nA with WDT off; ensure no pull-ups source current into floating I/O in Sleep, or the standby current will not achieve its nanoWatt-class figure of merit.
Route the ICSP pins (RB6/ICSPCLK and RB7/ICSPDAT, pins 27 and 28 on the 28-SSOP) to a 6-pin header for in-circuit programming and debugging with PICkit 4/5 or MPLAB Snap. Place the ICSP header at the board edge to avoid rework loops. The MCLR/RE3 pin (pin 1, shared with RA3) requires a 10kΩ pull-up to VDD and a 100nF cap to ground for the standard ICSP reset circuit; do not leave MCLR floating or programming will fail intermittently.
When using the on-chip op-amps as analog inputs, the input voltage range is rail-to-rail only when the OPA is configured in unity-gain buffer mode. In high-gain configurations (e.g., gain of 10), the output swing is limited to VDD-0.3V and VSS+0.3V. Always de-rate the analog input signal to keep the OPA output within its linear range. The Peripheral Pin Select (PPS) feature can remap most digital peripherals, but analog peripherals like the OPA outputs and ADCC inputs are NOT remappable - they remain on fixed pins (OPA1OUT on RA4, OPA2OUT on RA6, etc.).
The PIC16F1718-I/SS at 32MHz with full I/O toggling and active op-amps dissipates approximately 12-15 mA core current, yielding 60-80 mW at 5V supply. The 28-SSOP package has a θJA of approximately 80-100 °C/W, giving a 5-8°C junction-to-ambient rise - well within the 125°C absolute max at industrial ambient. No external heatsink is required. For extreme-ambient (>85°C) designs, the -E (Extended) temperature grade part is available with the same firmware compatibility.
