PIC16LF15325-E/ST 概要
An 8-bit PIC microcontroller is a Harvard-architecture CMOS device that combines a RISC-style CPU core, on-chip program memory, data RAM, and a rich peripheral set on a single die. Within the broader semiconductor taxonomy, it sits as MCU -> microcontroller -> embedded processor -> integrated circuit. The 'LF' prefix in the part number designates the low-voltage / low-power process variant optimized for portable and always-on applications, while 'F' denotes Flash program memory and '15325' identifies the specific memory/peripheral mix within the PIC16 family tree.
Key features include 14KB Flash / 1KB RAM / 256B EEPROM, up to 32 MHz CPU clock, four CLCs that implement combinatorial/sequential logic without CPU intervention, the CWG for synchronous MOSFET drive, and Microchip's Peripheral Pin Select (PPS) for flexible I/O mapping. The on-board 10-bit ADC with up to 12 channels supports sensor reading, while the 5-bit DAC enables setpoint generation in closed-loop control loops without an external converter.
Typical applications span consumer IoT sensor nodes, white goods user interfaces, low-cost motor control loops, LED lighting controllers, and battery-powered handheld instruments. The TSSOP-14 footprint suits compact PCBs where 8 to 14 GPIO lines are sufficient, and the XLP sleep currents below 100 nA enable multi-year coin-cell runtime. When designing, prioritize PPS configuration early to lock pin assignments, and verify that the chosen package variant's I/O count covers all required peripherals.

主な用途
PIC16LF15325-E/ST の用途: 6 件s: Battery-Powered IoT Sensor Node, White Goods User Interface Controller, Low-Voltage LED Lighting Controller, Compact Motor Control (Fan, Pump, BLDC), Portable Medical Monitoring Accessory, Industrial Sensor Transmitter (4-20 mA Loop).
Battery-Powered IoT Sensor Node
The PIC16LF15325-E/ST fits IoT sensor nodes through its XLP sleep current below 100 nA and 1.8V-3.6V operating range, enabling multi-year runtime from CR2032 coin cells or 2xAA batteries. The 10-bit ADC reads analog sensor outputs while the MSSP (SPI/I2C) interfaces with digital sensors and the EUSART links to UART-based radios. The 14KB Flash accommodates BLE beacon libraries or LoRaWAN device drivers; the 4 CLCs handle sensor-trigger logic without waking the core, and the CWG drives indicator LEDs or haptic feedback.
おすすめ
White Goods User Interface Controller
The PIC16LF15325-E/ST drives washing machine, dishwasher, and oven user interfaces by scanning capacitive touch buttons via the on-chip comparators and the CLC implementing touch-decision logic without CPU load. The 4 PWMs dim LED-backlit displays, while the CWG generates timing signals for piezo buzzers. Per the PIC16F153xx datasheet, the 32 MHz core runs GUI state machines with margin, and the 14KB Flash stores multilingual UI strings, fault logs in EEPROM, and wash-cycle recipes.
おすすめ
Low-Voltage LED Lighting Controller
The PIC16LF15325-E/ST serves 12V/24V LED lighting strips where its CWG produces the complementary drive signals for synchronous buck or boost converter MOSFETs and the 4 PWMs provide multi-channel dimming. The 5-bit DAC generates reference voltages for current-sense loops, while the comparators implement hardware over-current protection with cycle-by-cycle current limiting. Per the PIC16F153xx datasheet, the 14-TSSOP footprint fits slim constant-current driver PCBs and the XLP sleep current enables standby power below 100 mW per fixture.
おすすめ
Compact Motor Control (Fan, Pump, BLDC)
The PIC16LF15325-E/ST runs small BLDC and brushed DC motors in fans, water pumps, and small appliances. The CWG generates the complementary 6-step trapezoidal commutation signals for the gate driver, while the comparators execute back-EMF zero-cross detection. The 4 PWMs provide independent speed control and the ADC reads back-EMF and current-sense signals. Per the PIC16F153xx datasheet, the 32 MHz MIPS performance and CIP-driven waveform generation offload timing-critical tasks from the CPU, freeing it for application control logic.
おすすめ
Portable Medical Monitoring Accessory
The PIC16LF15325-E/ST powers portable medical accessories like pulse-oximeter dongles, pill-bottle reminders, and adherence trackers, leveraging its 1.8V minimum supply and XLP sleep below 100 nA. The 10-bit ADC reads photodiode signals from pulse-oximetry probes, the MSSP drives I2C medical sensors, and the EUSART connects to BLE modules streaming data to mobile apps. Per the PIC16F153xx datasheet, the -40C to +125C operating range covers clinical-environment thermal exposure.
おすすめ
Industrial Sensor Transmitter (4-20 mA Loop)
The PIC16LF15325-E/ST implements 4-20 mA current-loop sensor transmitters in industrial environments by digitizing sensor inputs through the 10-bit ADC, computing linearization in the 32 MHz core, and driving a current-setting DAC plus op-amp loop. The CLCs handle HART or proprietary modulation superimposition. Per the PIC16F153xx datasheet, the -40C to +125C extended temperature grade and the 14KB Flash accommodate sensor compensation tables, calibration constants in EEPROM, and HART protocol stacks.

設計ノート
Estimated: at VDD=3.3V with XLP sleep mode enabled, the PIC16LF15325-E/ST draws under 100 nA with WDT disabled and full RAM retention. For a CR2032 coin cell (220 mAh capacity) the theoretical sleep-only runtime exceeds 250 years, but practical battery self-discharge limits lifetime to ~10 years. Enable the RTCC with a 32.768 kHz external crystal to obtain accurate time-of-day wake-ups, and set the active CPU clock to 32 MHz only when needed to minimize average current. Place a 0.1 uF decoupling capacitor within 5 mm of the VDD pin and a bulk 1 uF to 10 uF capacitor near the MCU to suppress transient load steps during active mode.
Configure the Configuration Words (CONFIG1 through CONFIG5) early in firmware development: enable the Low-Voltage Programming (LVP) bit only if in-circuit programming is required, otherwise leave it disabled to free the RA0/PGD pin for GPIO use. The PPS (Peripheral Pin Select) feature must be unlocked via the CCP unlock sequence before any PPS register writes, and re-locked afterward to prevent accidental remapping at runtime. Do not leave floating analog inputs on unused ADC channels; either tie them to VDD/VSS or disable them in software to avoid shoot-through current in the input multiplexer.
Route the TSSOP-14 footprint with 0.65 mm pitch pads matching Microchip land pattern recommendation IPC-7351 nominal density. Place the MCU close to the crystal (if used) and keep crystal traces short, symmetrical, and ground-guarded. Route analog signals (ADC inputs, comparator inputs) away from PWM and CWG switching signals to minimize coupling. Add a ground pour under the TSSOP thermal pad area to lower the thermal resistance for the -40 C to +125 C extended temperature range parts, and consider stitching vias around the perimeter of the analog section for EMI suppression.
コンプライアンス情報
RoHS and lead-free compliance per Microchip product page and distributor listings (DigiKey 6593068, Mouser, TME, Newark). Part is not AEC-Q100 qualified; the standard PIC16LF15325-E/ST targets industrial and consumer applications.
