PIC16LF1825T-I/SL 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripherals (timers, ADC, comparators, communications, I/O). Within the broader power management and embedded hierarchy, an MCU sits between a digital signal processor (DSP) and a simple state machine: it runs deterministic firmware on a RISC or CISC core, exposes I/O to sensors and actuators, and is selected when latency, BOM cost, or standby current dominate the design. The PIC16F family uses a Harvard RISC core with single-cycle instructions and a 14-bit instruction word, balancing code density with deterministic interrupt response.
Key features include a 32 MHz internal oscillator with 4x PLL, a 10-bit ADC with up to 12 channels, multiple communication peripherals (I2C, SPI, EUSART), Capture/Compare/PWM modules, and mTouch capacitive-touch peripherals. The XLP feature set delivers nanoWatt sleep currents in the order of tens of nA with wake-on-change and low-power timer operation, enabling multi-year coin-cell or energy-harvested lifetimes. The 14-pin SOIC footprint keeps board complexity low for cost-sensitive human-interface, sensor, and appliance designs.
Typical applications include battery-powered IoT sensor nodes, capacitive-touch user interfaces, low-power wireless sensor hosts, handheld instruments, and home-automation edge nodes. The wide 1.8 V minimum supply voltage permits direct operation from single-cell Li-coin and dual-alkaline chemistries.
When laying out, dedicate the bottom copper layer to a continuous ground pour under the IC, keep the VCAP decoupling within a few millimetres of the pin, and select an external crystal or ceramic resonator away from noisy switching lines to preserve oscillator margins.
This page synthesizes distributor stock and pricing, drop-in alternatives, and practical low-power design guidance not assembled in the manufacturer datasheet, including pin-compatible LF variants across the PIC16F1825 family and tape-and-reel ordering codes for high-volume manufacturing.

主な用途
PIC16LF1825T-I/SL の用途: 6 件s: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Handheld Measurement Instrument, Home Automation Edge Node, Industrial Sensor Transmitter, Low-Power Wireless Sensor Host.
Battery-Powered IoT Sensor Node
The PIC16LF1825T-I/SL is well-suited for battery-powered IoT sensor nodes because its 1.8 V to 3.6 V operating voltage permits direct connection to single-cell Li-coin (CR2032, 3 V) or dual-AA alkaline stacks without boost topology, reducing BOM cost. The XLP nanoWatt sleep mode draws tens of nA in sleep with wake-on-change, so a typical sensor node waking every 60 s to sample and transmit achieves multi-year battery life per Microchip XLP benchmarks. The 32 MHz HFINTOSC with 4x PLL bursts active compute to under 5 ms per event, and the 10-bit ADC with up to 12 channels supports temperature, humidity, and battery-voltage monitoring simultaneously. Recommend pairing with a sub-GHz or BLE radio module via SPI/UART to build complete edge nodes.
おすすめ
Capacitive Touch User Interface
The integrated mTouch CTMU peripheral on the PIC16LF1825T-I/SL supports capacitive-touch sensing for buttons, sliders, and proximity sensors without external components beyond the sensor pads themselves, making it ideal for appliance user interfaces, lighting keypads, and remote controls. The CTMU charge-time measurement allows up to a dozen capacitive touch channels on the 12 I/O pins, and the 32 MHz core performs debounce, gesture recognition, and LED feedback in real time. The XLP sleep mode lets the MCU idle between user interactions at nanoWatt levels, extending battery life in remote controls. Per Microchip mTouch reference designs, the same hardware also supports proximity wake and water-tolerance.
おすすめ
Handheld Measurement Instrument
The PIC16LF1825T-I/SL fits handheld digital multimeters, environmental monitors, and portable medical instruments because its 14 KB Flash holds calibration tables and user-interface firmware, and the 10-bit ADC with up to 12 channels digitizes multiple sensor inputs. The 1.8 V to 3.6 V range supports direct 3 V battery operation, and the XLP sleep mode keeps idle current minimal during standby. The 14-SOIC package is small enough for slim handheld enclosures and is hand-solderable for low-rate builds, accelerating time-to-prototype. The industrial -40C to +85C temperature grade ensures outdoor or factory-floor operation.
おすすめ
Home Automation Edge Node
The PIC16LF1825T-I/SL serves as a low-power edge node in home-automation hubs for processing sensor inputs (PIR, temperature, light) and driving relay or TRIAC outputs for lighting, fans, or HVAC control. The on-chip EUSART and I2C allow connection to a host controller or to BLE/Zigbee radio modules, and the Capture/Compare/PWM modules generate precise timing for motor or TRIAC phase control. The 14 KB Flash fits Zigbee or BLE-stack-like logic for simple nodes, and the XLP mode keeps quiescent current below 100 nA when no events are sensed. Recommend pairing with a MAC-layer radio and a TRIAC driver for lighting control.
おすすめ
Industrial Sensor Transmitter
The PIC16LF1825T-I/SL is suitable for industrial 4-20 mA loop-powered sensor transmitters and discrete I/O modules because its wide 1.8 V to 3.6 V supply range and 32 MHz compute headroom allow conditioning, linearization, and HART-like protocol encoding on a single MCU. The industrial -40C to +85C temperature grade supports factory-floor environments, and the 256-byte EEPROM stores calibration and identification data over decades per Microchip endurance specs (100 k cycles minimum). The 14-SOIC footprint is small enough for DIN-rail transmitter heads. Recommend pairing with a precision op-amp and a 4-20 mA loop driver.
おすすめ
Low-Power Wireless Sensor Host
The PIC16LF1825T-I/SL works well as a host MCU for low-power wireless sensor networks (LoRa, Sigfox, sub-GHz proprietary) because the XLP feature set and 1.8 V minimum supply permit direct coin-cell operation, while the 32 MHz core executes protocol stacks and crypto at burst compute times under 5 ms per event. The EUSART handles transparent serial radio interfaces, and the 10-bit ADC digitizes sensor inputs for periodic sampling. The 14 KB Flash holds typical MAC-layer and application logic for simple nodes. Per Microchip XLP benchmarks, sensor nodes achieve multi-year battery life with periodic wake events.

設計ノート
PIC16LF1825T-I/SL supports 1.8 V to 3.6 V VDD. Place a 100 nF ceramic decoupling capacitor as close as possible (within 5 mm) to the VDD pin, plus a bulk 10 uF electrolytic or tantalum on the same rail. The VCAP pin requires a low-ESR 1 uF to 10 uF ceramic capacitor (typically 4.7 uF) tied to VSS to stabilize the internal voltage regulator, and inadequate capacitance here causes POR failures and erratic resets per Microchip errata guidance.
Keep the crystal or ceramic resonator traces (OSC1/OSC2) short and shield them with a ground pour on both sides. Route the I2C lines (SDA/SCL) away from switching converter traces, and place 4.7 kohm pull-ups on SCL and SDA if the MCU uses open-drain mode. Reserve the bottom copper layer as a continuous ground pour under the IC for thermal dissipation and EMI suppression. The 14-SOIC footprint gives adequate creepage for industrial 24 V adjacent rails when the layout avoids copper runs between pins.
Do not skip the MCLR pull-up on the RA5/MCLR pin; a floating MCLR causes spurious resets. Do not exceed VDD=3.6 V on the LF variant even briefly, or the internal voltage regulator enters dropout. When using HFINTOSC at 32 MHz with PLL, ensure VDD is at least 2.7 V to maintain oscillator accuracy. CTMU mTouch calibration constants should be stored in EEPROM and loaded at boot, not hard-coded, since touch pad capacitance drifts with temperature and humidity.
At full 32 MHz active compute in the 14-SOIC package with theta_JA approximately 100 C/W (estimated from SOIC thermal modeling), continuous full-bandwidth compute at room ambient typically holds junction temperature below 70 C. Sleep mode draws microAmps so thermal stress is negligible. For high-duty-cycle applications with all I/O active, verify junction rise with a thermocouple during worst-case characterization.
