MPN: PIC16LF15325T-I/SL ✓ Hoạt độngPIC16LF15325T-I/SL Tóm tắt
What is an 8-bit microcontroller (MCU)? It is a single-chip processor that integrates a CPU core, program memory (Flash), data memory (RAM), and peripherals on one die. Within the broader taxonomy: microcontroller -> embedded processor -> semiconductor IC. The PIC16LF15325T-I/SL sits in the XLP (eXtreme Low Power) subfamily of Microchip's mid-range PIC16 portfolio, designed for battery-powered and energy-harvesting applications where sleep-mode current and peripheral wake-up flexibility are primary design constraints.
Key features include 14 KB (8K x 14 words) self-programmable Flash, 1 KB SRAM, four 10-bit PWMs, a 5-bit DAC plus a 5-bit reference, a 10-bit ADC with computation, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and two EUSART/SPI/I2C peripherals. The XLP architecture delivers typical sleep currents of 50 nA and watchdog timer currents around 500 nA, enabling multi-year battery life in duty-cycled designs.
The device uses an enhanced mid-range 8-bit CPU with a 14-bit instruction word and 16-level hardware stack, executing most instructions in one instruction cycle. The integrated Core Independent Peripherals (CIPs) - CLC, CWG, NCO, and ADC with computation - let complex timing and signal-conditioning tasks run without CPU intervention, freeing the core to remain in sleep until a real event occurs.
Typical applications include IoT sensor nodes, battery-powered wireless transmitters, wearable health monitors, remote controls, smart-home sensor endpoints, and low-cost motor-control boards where PWM + CWG drive H-bridge stages. The wide 1.8V-3.6V operating range supports both single-cell lithium and dual-alkaline battery packs.
When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to VDD and tie unused I/O to defined logic levels to minimize current leakage. The 'LF' prefix denotes the low-voltage (1.8V min) variant - confirm rail compatibility if migrating from a PIC16F15325.

Ứng dụng tiêu biểu
PIC16LF15325T-I/SL phù hợp cho 7 Áp dụngs: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Remote Controls and RF Key Fobs, Smart-Home Sensor Endpoints, Low-Cost Motor-Control / Fan Drivers, Industrial Sensor Signal Conditioning, LED Lighting Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16LF15325T-I/SL is purpose-built for duty-cycled IoT sensor endpoints that spend most of their life in sleep. The 50 nA typical sleep current at 1.8 V plus ADC2 with computation allows the CPU to remain dormant while the ADC oversamples a sensor autonomously. With 14 KB Flash it accepts firmware for BLE/Zigbee host stacks on a companion radio, and the 1.8-3.6 V rail supports single-cell Li-ion or 2xAA alkaline packs directly without an LDO.

Wearable Health Monitors
For wrist wearables and disposable health patches, the PIC16LF15325T-I/SL's XLP sleep current and integrated peripherals (4 CLCs, ADC2, 2 comparators) eliminate the external op-amp chain typically used for bio-signal conditioning. The 32 MHz core executes signal-processing at low active currents. Pairing with a 3.0 V coin cell yields multi-month battery life when the MCU spends >99% of the time in sleep, waking only on heartbeat or motion interrupts.
Được đề xuất
Remote Controls and RF Key Fobs
Key fobs and IR/RF remotes benefit from the PIC16LF15325T-I/SL's 50 nA sleep current plus on-chip EUSART/SPI/I2C to drive low-cost 433 MHz / sub-GHz transceivers. The CLC (Configurable Logic Cell) can implement encoder waveforms in hardware so the CPU stays asleep. A single CR2032 3 V coin cell sustains the design for years given typical button-press duty cycles.
Được đề xuất
Smart-Home Sensor Endpoints
Smart-home temperature, occupancy, and air-quality nodes leverage the PIC16LF15325T-I/SL's ADC2 with computation to average sensor data in hardware, freeing CPU cycles. The 4 PWMs and CWG can directly drive LED indicators or small buzzers without external driver ICs. The 1.8-3.6 V supply range enables direct battery or energy-harvesting source connection.
Được đề xuất
Low-Cost Motor-Control / Fan Drivers
The PIC16LF15325T-I/SL's CWG (Complementary Waveform Generator) plus 4 PWMs drive a 3-phase or H-bridge stage for small BLDC fans, pumps, and solenoid drivers. ADC2 measures back-EMF and current sensing without off-chip components. The 14-pin SOIC footprint is compact enough for inline-mounted driver boards in appliances, and the XLP sleep current enables standby-mode energy compliance.
Được đề xuất
Industrial Sensor Signal Conditioning
In factory automation, the PIC16LF15325T-I/SL provides on-chip CLC logic for programmable analog filtering, two comparators for window detection, and the ADC2 for high-accuracy ratiometric measurements. The 1.8-3.6 V range and 32 MHz core let it serve as a low-cost front-end that digitizes 4-20 mA / 0-10 V sensor signals and outputs SPI/I2C to a host PLC, running from a 3.3 V LDO off the 24 V industrial bus.
Được đề xuất
LED Lighting Controllers
For addressable LED strip controllers and architectural lighting, the PIC16LF15325T-I/SL's 4 PWMs plus CWG drive multiple MOSFETs at high resolution for smooth dimming. The 2 EUSART ports handle DMX512 / SPI / I2C simultaneously. Sleep current of 50 nA keeps standby power below 100 uW for energy-star compliance when the LEDs are off but the controller remains on the bus.

Ghi chú thiết kế
Place a 0.1 uF ceramic decoupling capacitor between VDD (pin 1) and VSS (pin 8) with the shortest possible PCB trace (less than 3 mm to the MCU body). For sleep-current-sensitive designs add a 10 uF bulk capacitor on the VDD rail to prevent inrush spikes when the ADC or EUSART wakes; this stabilizes the rail before the XLP idle of 50 nA resumes. Tie any unused I/O pin to VDD or VSS (never float) - floating inputs add 100-300 nA of leakage per pin into the XLP sleep budget.
Do not connect RA3/MCLR directly to VDD without a 10 kohm pull-up if you intend to use in-circuit serial programming (ICSP). A direct short to VDD prevents the programmer from pulling the line low to enter programming mode. The 'LF' suffix indicates a 1.8 V minimum - designs that previously used PIC16F15325T-I/SL on a 5 V rail MUST switch to the F variant or use a 3.3 V LDO; the LF variant will be damaged above 3.6 V on VDD.
The 14-pin SOIC (SL) footprint follows the JEDEC SO-14 standard with 1.27 mm pitch. Use 0.1 uF bypass on VDD, a 4-layer board with a continuous ground plane under the IC, and route the high-impedance ADC inputs (RA0-RA5) away from PWM and EUSART switching traces to avoid digital-coupling noise. Keep the ADC analog and digital ground return paths short to the IC's VSS pin to minimize ground-bounce errors in the ADC2 conversion result.
The PIC16LF15325T-I/SL is a low-power CMOS device - thermal dissipation is dominated by I/O sink current (per-pin 25 mA max, total 200 mA budget). At maximum load, total power dissipation stays below 100 mW; no heatsink is required. Verify output-drive derating above 25 mA per pin and keep total GPIO current within the published 'Absolute Maximum Ratings' section of the datasheet to avoid long-term reliability drift.
