PIC18LF25J10-I/SS Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (timers, ADC, UART, I2C, SPI, PWM) into one IC. The PIC18 family uses an enhanced 8-bit Harvard RISC architecture with hardware multiplier and indexed addressing, slotting between simpler 8-bit MCUs (PIC10/12/16) and higher-end dsPIC/MIPS Cortex-M devices. PIC18J-series parts specifically add deep-sleep nanoWatt XLP modes that draw only nanoamps in retention, which extends battery life across years of unattended operation.
Key features of the PIC18LF25J10 include 32KB (16K x 16) Flash, 1024 bytes of SRAM, a 10-bit ADC with up to 13 input channels, two analog comparators, one 8-bit and three 16-bit timers, two MSSP (I2C/SPI) modules, an enhanced USART, and 21 digital I/O pins. The nanoWatt XLP technology enables ultra-low-power sleep modes with consumption under 100 nA, and the wide 2.0V-3.6V supply supports single-cell Li-ion or two-AA designs without level shifting.
Architecturally, this part uses a 16-bit instruction word and 8-bit data path executed in two cycles (or one with the 40 MHz Fosc = 10 MIPS instruction throughput), giving noticeably faster execution than PIC16 while preserving peripheral compatibility. The PIC18J family integrates on-chip voltage regulation and supports both internal and external oscillator sources for flexible clocking.
Typical applications include battery-powered sensor nodes, small home appliances, low-end human-interface devices, USB-less peripherals, industrial sensor conditioning, and battery chargers. It is widely used as a lower-memory complement to the 64KB PIC18F25K22 or as a low-power alternative to legacy PIC18F2420 designs.
When designing with this device, ensure your programmer supports the ICSP ICD-3 / PICkit-3 / PICkit-4 interfaces to leverage boundary-scan and runtime debugging, and observe decoupling requirements (100 nF + bulk) on VDD/VDDcore. Battery-backed designs should configure the deep-sleep modes using the RTCC and WDT to achieve sub-microamp quiescent current.

Typische Anwendungen
PIC18LF25J10-I/SS ist geeignet für 6 Anwendungs: Battery-Powered Sensor Node, Home Appliance Control Board, Industrial Sensor Conditioning Module, USB-less Peripheral / HID-Lite Device, Battery Charger Controller, Medical / Health Monitoring Device.
Battery-Powered Sensor Node
The PIC18LF25J10-I/SS is well suited for unattended sensor nodes powered by 2 AA cells or a coin cell, where its nanoWatt XLP Deep Sleep mode holds current consumption under 100 nA. Combined with the 10-bit ADC, two analog comparators, and configurable timer-driven wake sources, an MCU can sample a thermistor or accelerometer every few seconds and remain on a single battery for years. Its 32 KB Flash holds protocols like Modbus over RS-485 or BLE-beacon firmware. The wide 2.0-3.6V range eliminates the need for a boost regulator, simplifying the BOM.
Empfohlen
Home Appliance Control Board
In small home appliances such as coffee machines, blenders, or fan controllers, the PIC18LF25J10-I/SS replaces legacy bipolar logic with deterministic 10 MIPS performance. Its 21 I/O pins drive keypad scanning, triac-fired AC loads, LED indicators, and rotary encoder inputs; the 10-bit ADC reads mains-scaled voltage and current sense resistors for soft-start control. The 2.0-3.6V supply is compatible with a capacitive-drop + LDO front end for safe mains isolation. Industrial -40C to +85C rating supports operation behind ovens and inside unheated enclosures.
Empfohlen
Industrial Sensor Conditioning Module
The 28-SSOP PIC18LF25J10-I/SS handles 4-20 mA loop-powered transmitters and bridges small sensor signals to SPI/I2C peripherals. Its analog comparators drive interrupt-based threshold detection without polling overhead, while the 10-bit ADC delivers 1 mV resolution on a 3.3 V supply - sufficient for thermocouple or strain-gauge pre-conditioning. Two MSSP modules simultaneously run an I2C DAC channel and an SPI LCD driver, and the EUSART streams data over RS-485. ECCN-controlled but RoHS-compliant, the part is widely accepted in factory automation.
Empfohlen
USB-less Peripheral / HID-Lite Device
For HID-class peripherals without USB, the PIC18LF25J10-I/SS hosts PS/2, IrDA, or simple GPIO-based interfaces to legacy keyboards, mice, remote controls, or barcode scanners. Its EUSART and MSSP modules interface with IR LED receivers, while timer-driven PWM drives buzzer tones for keystroke feedback. The 32 KB Flash accommodates USB-HID stacks or vendor-specific command sets for industrial scanners. Designers can move to the PIC18F25J10 if 5V I/O is later required without changing the PCB.
Empfohlen
Battery Charger Controller
The PIC18LF25J10-I/SS suits low-power Li-ion or Ni-MH charging controllers where its ADC samples cell voltage and current, while PWM generated from a 16-bit timer regulates a buck converter or linear pass element. The nanoWatt XLP sleep with RTCC wakes the part periodically to top-up the battery, and the EUSART reports SoC data to a host MCU via RS-232 or RS-485. The 28-SSOP footprint is well suited to compact charger boards where thermal dissipation must be limited to less than 50 mW.
Empfohlen
Medical / Health Monitoring Device
In medical peripherals such as handheld blood-pressure monitors, pulse oximeter front-ends, or electronic thermometer bases, the PIC18LF25J10-I/SS provides precise timing for sensor drive and DSP-light filtering on 8-bit MCU signals. The analog comparators enable fast threshold detection of pulse waveforms while the 10-bit ADC accurately digitizes the slow envelope. RoHS compliance, industrial -40C to +85C operating range, and Microchip's medical-grade change notifications ease ISO 13485 vendor-management qualification.

Designhinweise
Estimated: To maximize battery life, configure the MCU in Deep Sleep with the RTCC running and the WDT disabled. Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD/VDDcore pins and a low-ESR 10 uF bulk capacitor within 10 mm. Avoid using the internal POR/BOR reset circuits if the supply ramps very slowly; instead, hold MCLR low until VDD is stable. Use an LDO such as the MCP1700-33 instead of a switching regulator if the analog front-end is sensitive to high-frequency ripple.
Keep the ICSP programming pins (PGED1/PGEC1, MCLR) on dedicated test points or header pads; the MCLR pin must have a 10 kohm pull-up and a 100 nF cap to ground for in-circuit debug operation. SSOP package requires 0.65 mm pitch copper pads and reflow profile per IPC/JEDEC J-STD-020 for moisture-sensitive level classification. Keep analog traces away from switching nodes and use a ground plane stitch beneath the part for thermal dissipation.
Do not exceed the absolute maximum VDD of 3.6 V on the LF variant - applying 5 V damages the part. When migrating from the LF to the F variant, recompile with the appropriate configuration bits; the F variant uses different ADC reference behavior. The 28-SSOP and 28-SPDIP variants share the same die but only the SSOP is surface-mount; pinout of the 28-QFN (/ML) variant does NOT match. Always verify your layout against the 28-SSOP footprint supplied in the Microchip device pack.
For SPI communications up to 10 MHz, keep MISO/MOSI/SCK traces short (≤50 mm) and matched to within 5 mm. Place 33 ohm series termination on SCK if the bus exceeds 30 mm or if multiple slaves are chained. For I2C, use 4.7 kohm pull-ups at 100 kHz and 2.2 kohm at 400 kHz, considering the total bus capacitance of all slaves plus MCU capacitance plus PCB trace capacitance.
Compliance-Informationen
RoHS compliant per Microchip product page. Industrial -40C to +85C temperature grade. Not AEC-Q100 qualified; for AEC-Q100 automotive designs, Microchip recommends PIC18F25K22-I/SS instead.
