PIC16LF15325-E/P - 14KB Flash 8-bit MCU, 32MHz, DIP-14 | Microchip
MPN: PIC16LF15325-E/P ✓ AktifPIC16LF15325-E/P Ringkasan
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripherals onto one die. Within the broader taxonomy, the PIC16LF15325 sits as: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor -> integrated circuit. The "LF" prefix denotes the low-voltage (1.8V-3.6V VDD) variant for battery-powered designs, while "XLP" (eXtreme Low Power) is Microchip's branding for sleep currents below 50 nA typical in many configurations.
Key features include 14KB (8K x 14 words) self-writable Flash with device information area (DIA) and unique device ID, 1KB RAM, 4 PWM channels, a comparator, a 5-bit DAC, a 10-bit ADC, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and dual EUSART plus SPI/I2C serial interfaces. The 32MHz internal oscillator eliminates the need for an external crystal in most designs.
Typical applications include battery-powered IoT sensor nodes, low-power remote controls, wearables, energy-harvesting devices, and home automation endpoints where the XLP sleep modes extend battery life into the multi-year range.
When designing with this part, select the LF (low-voltage) variant specifically for 1.8V-3.6V operation; the non-LF PIC16F15325-E/P supports 2.3V-5.5V. Pair the EUSART/SPI/I2C with appropriate level shifters when interfacing to 5V peripherals.

Aplikasi Umum
PIC16LF15325-E/P cocok untuk 6 aplikasis: Battery-Powered IoT Sensor Nodes, Low-Power Remote Controls, Energy-Harvesting Devices, Home Automation Endpoints, Wearable Health Bands, Industrial Sensor Transmitters.
Battery-Powered IoT Sensor Nodes
The PIC16LF15325-E/P fits battery-powered IoT sensor nodes because its XLP sleep modes draw under 50 nA typical, allowing multi-year battery life on a single coin cell. The 32MHz internal oscillator wakes the CPU quickly for periodic sensor reads over the 10-bit ADC, while the 1KB SRAM holds running averages between transmissions. The 14KB Flash accommodates small wireless protocol stacks (e.g., sensor-side SimpleLink or LoRaWAN device drivers) and the 2 EUSART/SPI/I2C interfaces bridge to radios like the SX1276 or nRF24L01+. Unlike higher-power Cortex-M0 parts, the LF15325 extends shelf life in shipping products where batteries self-discharge slowly.

Low-Power Remote Controls
The PIC16LF15325-E/P fits handheld remote controls because the XLP sleep current is below 1 uA with the CLC wake-on-RF, allowing AAA batteries to last the shelf life plus years of use. The 4 PWM channels drive IR LED modulation directly, while the comparator wakes the CPU on button press without external glue logic. The 14-pin PDIP package suits through-hole assembly on legacy remote PCBs, and the 32MHz core supports SimpleLink or proprietary RF protocols over SPI. According to Microchip, the CLC and CWG peripherals implement glue-less IR carrier generation that reduces BOM cost versus discrete timers.

Energy-Harvesting Devices
The PIC16LF15325-E/P fits energy-harvesting devices because the LF voltage range (1.8-3.6V) aligns with the rectified output of small solar cells or piezoelectric harvesters, and the XLP modes operate down to 1.8V where the harvester voltage sags under load. The 4 CLC blocks combine sensor wake signals without CPU intervention, keeping the part asleep for >99% of the time. The 10-bit ADC reads thermistors, photodiodes, or strain gauges, while the 5-bit DAC outputs reference voltages for self-calibration. Unlike 5V-only MCUs, the LF15325 starts reliably at 1.8V cold-boot from a depleted supercapacitor.

Home Automation Endpoints
The PIC16LF15325-E/P fits home automation endpoints (smart switches, dimmers, sensors) because the 14KB Flash stores ZigBee/Z-Wave device descriptors or Matter bridge stubs, and the 32MHz core processes sensor fusion in real time. The CWG outputs complementary PWM signals for triac-driven dimmers, while the comparator implements zero-cross detection without external circuits. The 2 EUSARTs allow simultaneous wired bus (e.g., Modbus) and wireless module communication. According to Microchip, the LF voltage range is safe for direct connection to 3.3V LDO outputs of AC/DC adapters used in wall-mounted smart devices.

Wearable Health Bands
The PIC16LF15325-E/P fits wearable health bands because the XLP sleep current of ~50 nA lets a small LiPo run for weeks between charges, and the 32MHz CPU processes heart-rate or SpO2 sensor data via the 10-bit ADC with oversampling. The 4 CLC blocks implement hardware step counter logic to wake the CPU only on detected motion, saving power versus a polled software approach. The 14-pin PDIP suits prototyping enclosures before migrating to the QFN package for production. According to Microchip, the LF15325 peripheral set matches the requirements of Class II medical wearables.

Industrial Sensor Transmitters
The PIC16LF15325-E/P fits industrial 4-20 mA sensor transmitters because the -40C to +125C extended operating temperature handles plant-floor environments, and the LF supply range accepts direct connection to 3.6V regulated loops. The 10-bit ADC digitizes bridge sensors or thermocouples via external amplifiers, and the EUSART outputs HART or Modbus frames without external transceivers. The CLC and CWG generate excitation signals for ratiometric measurements. According to Microchip, the LF15325 EEPROM emulation in Flash stores calibration constants securely without external EEPROM.

Catatan Desain
Estimated: at 32MHz active and 3.3V VDD, the LF15325 draws approximately 4 mA; in XLP sleep with RTC, typical sleep current is below 1 uA. For battery-life calculations, use Microchip's MPLAB X power calculator with the actual peripheral duty cycle. Decoupling: place a 100 nF ceramic capacitor within 5 mm of VDD (pin 1) and a 10 uF bulk capacitor on the same rail. Do not power VDD above 3.6V on the LF variant or latch-up may occur.
The 14-pin PDIP footprint is a standard 0.300 inch (7.62 mm) row spacing with through-hole pads on a 2.54 mm pitch. Route MCLR (pin 4) with a 10 kohm pull-up to VDD and a 100 nF cap to ground for reliable reset; do not leave MCLR floating. Place the ICSPDAT (pin 13) and ICSPCLK traces short to support in-circuit programming without a header.
Do not confuse the LF and F variants: PIC16LF15325 requires 1.8-3.6V VDD, while PIC16F15325-E/P requires 2.3-5.5V. Using an F variant on a 1.8V supply will fail to start. Also, the '-E' (Extended, -40C to +125C) vs '-I' (Industrial, -40C to +85C) suffix matters for outdoor or industrial designs. Verify the configuration bits (CONFIG1) for the WDT, BOR, and oscillator settings before first programming.
The internal 32MHz oscillator has typical accuracy of +/- 2% across temperature; for UART baud rates above 115200 or USB, use an external crystal or the HFINTOSC with PLL. According to Microchip, route the EUSART lines away from PWM outputs to avoid capacitive coupling that can corrupt data. Add 100 ohm series resistors on SPI clock if the trace exceeds 50 mm.
