PIC16LF15325-E/JQ - 8-bit MCU, 14KB Flash, 32MHz XLP | Microchip
MPN： PIC16LF15325-E/JQ ✓ 啟用中PIC16LF15325-E/JQ 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and peripherals such as timers, ADCs, and communication interfaces. Within the broader taxonomy, an 8-bit MCU sits below 16-bit and 32-bit microcontrollers in computational capability, but excels in deterministic real-time response, low cost, and ultra-low power consumption. The PIC16LF15325-E/JQ combines an 8-bit PIC16 RISC core with Core Independent Peripherals (CIPs), positioning it within the low-power edge controller segment of the semiconductor market.
Key features include four 10-bit PWMs, a 5-bit DAC, a 10-bit ADC with computation, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), two EUSART modules, SPI/I2C interfaces, and a temperature indicator. The XLP technology provides sleep currents as low as a few hundred nanoamps, and the integrated 32MHz oscillator eliminates the need for an external crystal in many designs.
Architecturally, the device uses a Harvard architecture with a 14-bit instruction word and separate data bus, achieving single-cycle execution of most instructions. The Memory Access Partition (MAP) feature allows custom bootloader and data EEPROM emulation, while Device Information Area (DIA) provides unique per-chip serialization for security and calibration.
Typical applications include IoT sensor nodes, wearable health monitors, battery-powered instrumentation, low-power wireless remotes, smart home end nodes, and consumer electronics requiring extended battery life. The combination of small UQFN package and XLP characteristics makes it well-suited for space-constrained portable designs.
When designing with this part, allocate the 1KB RAM carefully - it is sufficient for state machines and small protocol stacks but limited for buffering. Use the CWG with the 10-bit PWM for LED lighting or motor control topologies, and leverage CLC for glue-logic replacement to reduce BOM cost and PCB area.

典型應用
PIC16LF15325-E/JQ 適用於 6 應用s: IoT Sensor Node, Wearable Health Monitor, Battery-Powered Instrumentation, Smart Home End Node, Consumer Remote Control, LED Lighting Control.
IoT Sensor Node
The PIC16LF15325-E/JQ fits IoT sensor node designs because its XLP technology delivers nanoWatt sleep currents while the 32MHz core wakes instantly to process sensor data. The 10-bit ADC with computation performs hardware averaging and threshold detection, offloading the CPU and enabling years of battery life on a single coin cell. The four CLC blocks replace external glue logic for sensor conditioning, and the 4x4 mm UQFN package fits inside space-constrained sensor housings.
推薦
Wearable Health Monitor
The PIC16LF15325-E/JQ is well suited for wearable health monitors where the extended -40C to +125C operating range tolerates body heat and ambient extremes. The 5-bit DAC and two comparators drive the optical heart-rate sensor front-end, while the CWG controls haptic feedback PWM for silent alerts. XLP sleep modes combined with the EUSART allow wake-on-interrupt BLE bridging while consuming under 1 uA standby - critical for multi-day wearable operation.
推薦
Battery-Powered Instrumentation
For handheld multimeters and portable test gear, the PIC16LF15325-E/JQ offers 14KB of Flash to store calibration constants, user interface strings, and measurement algorithms in a single device. The dual EUSART allows simultaneous USB-UART bridging and isolated serial port communication, while the 10-bit ADC with computation delivers oversampling and digital filtering for accurate readings. The 1.8V minimum supply lets designers power directly from two AA cells without a boost regulator.
推薦
Smart Home End Node
The PIC16LF15325-E/JQ is an ideal smart home end-node controller because its CLC and CWG blocks implement zero-crossing triac control and capacitive-touch sensing without external logic ICs. SPI/I2C peripherals drive displays, EEPROM, and external sensors, while the EUSART interfaces with wireless modules. The 16-UQFN (4x4 mm) package drops directly onto compact switch and sensor PCBs, and XLP modes enable battery-powered wireless sensors lasting 5-10 years.
推薦
Consumer Remote Control
The PIC16LF15325-E/JQ fits IR/RF remote controls because its XLP sleep current and fast wake-up support coin-cell operation for years. The CWG drives accurate 38-56 kHz carrier modulation for IR transmission, while the EUSART or SPI links to sub-GHz or BLE companion modules. The 4x4 mm UQFN package suits slim remote enclosures, and 14KB Flash accommodates multiple device protocols and button mapping tables.
推薦
LED Lighting Control
For LED drivers and architectural lighting, the PIC16LF15325-E/JQ provides four 10-bit PWM channels and one CWG capable of driving half-bridges with programmable dead-band. The 5-bit DAC sets LED current references, while the comparators perform over-temperature and over-current protection autonomously via CIPs. Low-voltage 1.8V operation supports direct LiFePO4 battery-powered fixtures with no auxiliary regulator.

主要差異化特點
- Extended -40C to +125C operating temperature grade (對比PIC16LF15325-I/JQ)
- Lowest supply voltage range in the family (1.8V) (對比PIC16F15325-E/JQ)
- Highest Flash/RAM density in the 14/16-pin PIC16F153xx lineup (對比PIC16LF15324-I/JQ)
設計說明
Estimated: At 3.3V VDD, 32MHz active, the PIC16LF15325-E/JQ core draws approximately 2-3 mA. In Sleep mode with WDT disabled, current drops below 50 nA. For battery-life calculations, measure your actual duty cycle: a sensor node active 0.1% of the time will see average current dominated by sleep current, enabling multi-year coin-cell operation. Always include a 100 nF decoupling capacitor within 5 mm of the VDD pin.
The 16-UQFN (4x4) exposed thermal pad MUST be soldered to a grounded copper pour of at least 4x4 mm for proper thermal and electrical performance. Without the EP connection, the device may exhibit erratic behavior, increased EMI, and thermal shutdown at lower-than-expected loads. Stencil design should use multiple smaller openings for the EP to ensure void-free solder joints per IPC-7525.
Do not skip the configuration bits setup in your firmware - leaving the watchdog timer enabled unintentionally will reset the device every few ms. Also verify MCLR function vs. RA3 I/O selection in CONFIG1; using RA3 as digital I/O disables the external reset and complicates in-circuit serial programming (ICSP). The ICD debugger pin assignments for UQFN differ from PDIP variants - consult the datasheet debug section.
Route the ICSP programming signals (ICSPCLK/ICSPDAT) with no series resistors when used as PGD/PGC, and place a 4.7 kohm pull-up on MCLR to VDD through the diode. Keep analog traces (ADC inputs, comparator inputs, DAC output) away from PWM and digital switching signals to avoid coupling noise into sensitive measurements. Use a ground pour on layer 2 with vias stitching around the UQFN package perimeter.
