PIC16LF15325-I/ST 概要
An 8-bit microcontroller (MCU) is a small computing-on-a-chip built around an 8-bit data path, integrating CPU, Flash, RAM, EEPROM, and a rich mix of analog and digital peripherals on a single die. PIC microcontrollers from Microchip use a RISC-like Harvard architecture with a small, deterministic instruction set, occupying a mid-position in the taxonomy: microcontroller -> embedded controller -> semiconductor IC. They are widely used where low power, simple peripherals, and rapid interrupt response dominate over raw computational throughput.
Key features of the PIC16LF15325 include four 10-bit PWM channels, a comparator, a 5-bit DAC, a 10-bit ADC with up to 11 channels, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), two Enhanced USART modules (EUSART) supporting LIN and RS-485, plus SPI and I2C (MSSP) peripherals. Core Independent Peripherals (CIPs) allow many functions - waveform generation, signal conditioning, custom logic - to run without CPU intervention, drastically lowering active current and simplifying real-time firmware.
The device implements Microchip's eXtreme Low-Power (XLP) technology, with a typical sleep current on the order of nanoamps and multiple power-managed operating modes. The internal 32MHz high-speed oscillator eliminates the need for an external crystal in many designs, and the integrated 32kHz low-power LFINTOSC supports RTC-like background tasks. The architecture pairs a 14-bit instruction word with a separate 8-bit data path, allowing single-cycle execution of most instructions at up to 8 MIPS.
Typical applications include IoT sensor nodes, battery-powered home automation endpoints, wearable health monitors, low-power wireless HMI controls, automotive body and lighting sub-modules, and small appliance user interfaces. The combination of CLC-based custom logic and PWM/CWG peripherals makes the part especially well suited to driving LEDs, small motors, and fan tachometer inputs. Compared with discrete timer + op-amp implementations, this single-chip solution reduces BOM cost and PCB area while improving EMC behavior due to on-chip integration.
Designers should note that the 'I' suffix indicates the -40C to +85C industrial temperature range, and the '/ST' suffix identifies the 14-pin TSSOP package. The part is in-circuit serial-programmable via ICSp and is supported by the MPLAB X IDE, MPLAB XC8 compiler, and Microchip's Code Configurator (MCC) plug-in for graphical peripheral setup.

主な用途
PIC16LF15325-I/ST の用途: 6 件s: Battery-Powered IoT Sensor Node, Home Automation / Smart Switch Endpoint, Wearable Health Monitor, Automotive Body and Lighting Module, Small Appliance User Interface, Industrial Sensor Transmitter (4-20 mA / 0-10 V).
Battery-Powered IoT Sensor Node
The PIC16LF15325-I/ST is well suited to coin-cell or 2x AA battery sensor nodes because its XLP technology delivers sleep current on the order of nanoamps and the 1.8V-3.6V VDD range matches 3V lithium chemistries directly. The on-chip 10-bit ADC with up to 11 channels interfaces directly to temperature, humidity, or MEMS motion sensors, while the 4 CLC blocks can implement edge-event logic (rate-of-change, thresholding) without waking the CPU. The 14KB Flash comfortably holds BLE HCI host drivers or LoRa SX1276 control stacks, and the 32kHz LFINTOSC enables RTC-like periodic wake-up. Power-budget estimate: at 1 wake/minute with 5ms active time, average draw is ~10uA, giving >2 years from a CR2032.

Home Automation / Smart Switch Endpoint
For wall-mounted smart switches and dimmer endpoints, the PIC16LF15325-I/ST pairs the CWG (Complementary Waveform Generator) with the 4x 10-bit PWM channels to drive TRIAC, FET, or LED loads with zero-crossing timing accuracy. The 2x EUSART modules handle RS-485 or LIN communication for wired bus architectures, while the MSSP provides SPI for a local BLE/NFC companion chip. The 14-pin TSSOP fits behind a standard rocker switch wall plate, and the -40C to +85C industrial temperature range handles unheated junction boxes. The XLP sleep mode keeps the standby power below 0.5W - essential for meeting energy-efficiency regulations like ErP and Title 24.
おすすめ
Wearable Health Monitor
Wearable fitness bands and health patches benefit from the PIC16LF15325-I/ST's small TSSOP-14 footprint, XLP nanoamp sleep, and integrated 10-bit ADC for photoplethysmography (PPG) and skin-temperature sensing. The 5-bit DAC drives the LED bias current directly, while the comparator performs fast threshold detection on the photodiode return signal - all without waking the CPU thanks to the CLC peripherals. With 14KB Flash the part fits a heart-rate algorithm and BLE command layer; the 1.8V minimum VDD lets the design run from a rechargeable Li-Po cell down to near depletion, maximizing usable capacity. The industrial -40C to +85C range handles body-temperature operation reliably.
おすすめ
Automotive Body and Lighting Module
For interior lighting controllers, ambient LED drivers, and small body controllers (mirror adjusters, seat switches), the PIC16LF15325-I/ST offers the CWG for half-bridge LED driving, the 4x PWM for color-mixing RGB channels, and the EUSART for LIN bus communication to the body controller. While the 'I' grade is rated -40C to +85C, Microchip offers an AEC-Q100 'F' variant (PIC16F15325) for under-hood or harsher zones. The TSSOP-14 footprint is automotive-qualified-via-die per Microchip's product family roadmap. The 1.8V minimum VDD lets the part survive crank-down events down to ~6V battery systems (with external LDO).
おすすめ
Small Appliance User Interface
Coffee machines, air purifiers, and small kitchen appliances use the PIC16LF15325-I/ST to consolidate user-interface, sensor, and motor-control logic onto one chip. The 4x 10-bit PWM drives BLDC fan or pump speed via an external FET bridge, while the CLC implements custom timing logic for soft-start and over-current protection. The 5-bit DAC controls LED backlight brightness, the ADC reads NTC temperature sensors, and the EUSART links to a Wi-Fi/BLE companion for IoT-enabled variants. The TSSOP-14 hand-solders cleanly for low-volume products, and MPLAB X with the MCC code generator accelerates time-to-market for typical 30-100k unit annual volumes.
おすすめ
Industrial Sensor Transmitter (4-20 mA / 0-10 V)
Industrial loop-powered sensor transmitters benefit from the PIC16LF15325-I/ST's wide 1.8V-3.6V supply, on-chip 10-bit ADC for bridge sensor measurements, and 5-bit DAC for 4-20 mA current-loop output via an external op-amp. The CLC blocks implement the loop-current limiter without CPU intervention, and the EUSART links to a local HMI display or wireless gateway. The -40C to +85C industrial rating handles outdoor and factory-floor environments. The TSSOP-14 fits in the standard 24mm DIN-head transmitter housing alongside the loop-power regulation circuitry. Microchip's application note AN2334 covers loop-powered 4-20 mA design with PIC MCUs.

設計ノート
The PIC16LF15325-I/ST XLP technology requires careful firmware handling: clear all interrupt flags before entering Sleep, set unused peripherals to 'disabled' (not just 'unused') in PMDx registers, and route wake-up sources through the dedicated PIE/PIR bits so a pending interrupt does not block Sleep entry. Estimated worst-case sleep current with WDT disabled and all peripherals off is on the order of tens of nA at 3.3V - enough for CR2032 applications to exceed 2-year battery life with a 1Hz wake cadence.
ICSP pins RA0 (ICSPCLK) and RA1 (ICSPDAT) double as ADC inputs in the TSSOP-14 pinout. Place a 4.7k-10k pull-up on MCLR (RA3) and route ICSPCLK/ICSDAT signals with short, direct traces; long traces couple noise into the programming interface and produce intermittent ICD3/PICkit4 attach failures. Keep the ICSP connector (or pogo-pad footprint) on the production PCB even if you do not populate it - field firmware updates via ICSP are cheaper than recalls.
Do not skip the AVDD/AVSS decoupling network. The PIC16LF15325-I/ST shares analog and digital VDD on a single pin (no separate AVDD in TSSOP-14); place a 100nF X7R ceramic directly on VDD plus a 10uF bulk capacitor within 10mm. Also: the 5-bit DAC is unbuffered and has high output impedance (~10k ohm typical) - drive only high-impedance loads or buffer externally. CLC and CWG outputs must be physically remapped to available pins via PPS; not every internal signal can land on every pin.
The internal 32MHz HFINTOSC has +/-2% accuracy across -40C to +85C and 1.8V to 3.6V, which is acceptable for UART up to 19200 baud and PWM timing, but inadequate for EUSART at 115200 baud with a 0.5% stop-bit margin. For UART above 38400 baud, switch to the HFINTOSC with 4x PLL and enable the Auto-Baud Detector, or use an external 16MHz crystal on OSC1/OSC2 (note: in TSSOP-14 the dedicated crystal pins are shared with GPIO and require configuration trade-offs).
