PIC16LF1707T-I/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals such as ADCs, timers, communication interfaces (UART, SPI, I2C), and I/O pins. Within the broader taxonomy, the PIC16LF1707 is a Flash-based 8-bit MCU in the PIC16 enhanced mid-range family, sitting beneath 16-bit dsPIC and 32-bit ARM Cortex parts in computational power but excelling in cost-sensitive and battery-powered applications. The 8-bit architecture trades raw throughput for deterministic instruction execution, predictable interrupt latency, and an exceptionally mature toolchain.
Key features include operation from 1.8V to 3.6V (the LF prefix), an integrated 10-bit ADC with up to 17 analog channels, an 8-bit DAC, two 8-bit timers, one 16-bit timer, enhanced PWM modules, EUSART, MSSP (SPI/I2C), up to 18 general-purpose I/O pins, and the nanoWatt XLP sleep current below 1 µA. The internal 32 MHz oscillator eliminates the need for an external crystal in most designs, and the on-board ICD-friendly debug interface simplifies in-circuit programming.
Typical applications include low-power sensor nodes, IoT endpoints, wearable health monitors, battery-powered remote controls, LED lighting controllers, and consumer white-goods user interfaces. The wide analog integration also makes it attractive for touch/proximity sensing and small motor-control loops via PWM. The 20-SOIC footprint is hand-solderable and machine-solderable for prototyping as well as high-volume production.
When designing with this part, choose decoupling capacitors within a few millimeters of VDD and AVSS pins, reserve a dedicated ICSP header for programming/debug, and use the LF suffix to exploit the full 1.8V-3.6V supply range. This page synthesizes distributor pricing, drop-in alternatives within the PIC16 family, and practical design notes not found in the manufacturer datasheet.

主な用途
PIC16LF1707T-I/SO の用途: 7 件s: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Remote Control and Consumer White Goods, LED Lighting Controllers, Industrial Sensor Transmitters, Motor Control and Small Fan Drivers, Capacitive Touch User Interfaces.
Battery-Powered IoT Sensor Nodes
The PIC16LF1707T-I/SO fits battery-powered IoT sensor nodes because its nanoWatt XLP sleep current below 1 µA and 1.8V-3.6V supply range extend coin-cell or 2x AA battery life for years. The integrated 10-bit ADC with up to 17 channels directly digitizes temperature, humidity, and analog sensor outputs without external signal conditioning. Designers typically run the CPU at 32 MHz only for brief transmit bursts, then drop to 32 kHz sleep to minimize average drain.
おすすめ
Wearable Health Monitors
Wearable health monitors benefit from the PIC16LF1707T-I/SO's sub-microamp sleep modes, integrated 10-bit ADC for biosignal acquisition (pulse, skin conductance), and 20-SOIC footprint that fits small PCB assemblies. The on-board EUSART and MSSP connect directly to BLE modules such as the RN4870 for wireless telemetry. The 1.8V minimum voltage supports single-cell Li-ion chemistries down to depletion thresholds without brown-out resets in typical use.
おすすめ
Remote Control and Consumer White Goods
In remote controls and consumer white goods, the PIC16LF1707T-I/SO drives IR LEDs via PWM, scans capacitive touch buttons through the integrated ADC, and runs user-interface state machines on its 32 MHz core. The 3.5KB Flash comfortably holds protocol stacks (RC5, NEC) plus UI firmware. Its wide 1.8V-3.6V supply range tolerates AA/AAA battery voltage sag across months of standby use.
おすすめ
LED Lighting Controllers
LED lighting controllers leverage the PIC16LF1707T-I/SO's multiple PWM channels and 10-bit DAC to drive constant-current LED strings with smooth dimming. The 32 MHz CPU bandwidth executes color-mixing and temperature-compensation algorithms without saturating CPU cycles. EUSART and I2C peripherals interface to wireless modules or DMX512 controllers, and the industrial temperature grade suits indoor and outdoor luminaires.
おすすめ
Industrial Sensor Transmitters
Industrial 4-20 mA sensor transmitters use the PIC16LF1707T-I/SO to digitize bridge sensors via the 10-bit ADC, compensate for temperature and non-linearity in firmware, and output the analog current loop using PWM-filtered DAC techniques. The industrial -40°C to +85°C rating handles factory-floor and outdoor installations. The 20-SOIC footprint simplifies hand-rework during prototyping and field service.
おすすめ
Motor Control and Small Fan Drivers
Small BLDC fans and DC motor controllers use the PIC16LF1707T-I/SO's 16-bit timer plus PWM for commutation and speed regulation. The 32 MHz instruction rate supports sensorless back-EMF zero-crossing detection for cost-optimized fan designs. The integrated 10-bit ADC reads tachometer feedback or current sense, and the 20-SOIC footprint drops onto existing PIC16-based fan control boards with minimal PCB rework.
おすすめ
Capacitive Touch User Interfaces
Capacitive touch keypads and sliders use the PIC16LF1707T-I/SO's integrated 10-bit ADC and CVD (Capacitive Voltage Divider) peripheral for proximity-sensing electrodes without external touch ICs. The mTouch® sensing library from Microchip runs on this part with documented firmware examples, allowing 4-12 touch channels plus RGB LED feedback. The 32 MHz clock keeps touch-scan loop latency below 5 ms for responsive UX.

設計ノート
Decouple VDD (pin 13) and AVSS (pin 12) with a 100 nF ceramic capacitor placed within 5 mm of the package pin, plus a bulk 10 µF tantalum or ceramic capacitor on the supply rail. The PIC16LF1707 LF family supports 1.8V-3.6V; using an LDO such as MCP1700 keeps quiescent current under 1.6 µA, preserving nanoWatt XLP sleep-current advantages in battery-powered designs.
Do not drive MCLR/RA3 (pin 1) low during normal operation without a series resistor and proper ICSP header isolation - this pin serves as both Master Clear and programming voltage input. Failure to disable ICD or to provide proper ICSP isolation can prevent in-circuit programming or cause inadvertent resets when the pin is pulled low by neighboring circuitry. Reserve a 6-pin ICSP header (MCLR, VDD, VSS, PGD, PGC, AUX) per Microchip ICD layout guidelines.
Route the analog AVCC/AVSS pins separately from digital VDD/VSS when both are present on extended pinout variants (20-SOIC provides dedicated analog pins via RA0-RA5 channels). Keep analog traces short, avoid routing them parallel to PWM or switching signals, and surround analog inputs with a ground pour. For ADC accuracy below 1 LSB, add a small RC filter (100Ω + 100 nF) on noisy analog sources.
コンプライアンス情報
RoHS and REACH compliant per Microchip product declaration. Industrial -40C to +85C temperature grade; not AEC-Q100 qualified - choose PIC16F1707-E/SO or PIC16F1713-E/SO for automotive.
