PIC16LF1825-E/JQ - 8-Bit MCU 14KB Flash 32MHz XLP | Microchip
MPN： PIC16LF1825-E/JQ ✓ 啟用中PIC16LF1825-E/JQ 概覽
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (typically Flash), working RAM, and a rich set of on-chip peripherals such as timers, communication interfaces, ADCs, and digital I/O. In the broader system hierarchy, an MCU is a sub-class of microprocessor embedded ICs that combines compute, memory, and I/O on one die, eliminating the need for external RAM or program storage in cost-sensitive designs. Within the PIC family, the PIC16 mid-range core sits between the baseline PIC10/12 series and the high-performance PIC18 and dsPIC families.
Key features of the PIC16LF1825 include 14KB (8K x 14 words) Flash, 1KB RAM, 256 bytes EEPROM, 12 digital I/O pins, 32MHz internal oscillator, 10-bit ADC up to 12 channels, two PWM modules, two comparators, an 8-bit and a 16-bit timer, an MSSP/I2C/SPI peripheral, an EUSART, and a 32kHz low-power internal oscillator for RTC-style sleep modes. The 'LF' prefix designates the wide-voltage 1.8V-3.6V variant optimized for low-power and battery-backed applications. The 'E' suffix denotes the extended (-40C to +125C) operating temperature range.
Typical applications for the PIC16LF1825 include low-power IoT sensor nodes, battery-powered remote controls, capacitive touch user interfaces (mTouch), wearable health monitors, small home appliances, LED lighting controllers, and automotive body electronics modules. Designers choose this MCU when they need more Flash and RAM than a PIC12 or PIC16F1822 can offer but want to stay in the familiar PIC16 toolchain under MPLAB X IDE and XC8 compiler.
When designing with the PIC16LF1825-E/JQ, pay attention to the UQFN-16 (JQ) footprint: it requires a properly sized EP thermal/exposed-pad land on the PCB for mechanical reliability and for the lowest possible thermal resistance. Use MPLAB X IDE with the XC8 compiler and PICkit 3/4 or MPLAB SNAP for programming/debugging.

典型應用
PIC16LF1825-E/JQ 適用於 6 應用s: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Wearable Health Monitor, LED Lighting Controller, Small Home Appliance Control, Automotive Body Electronics Module.
Battery-Powered IoT Sensor Node
The PIC16LF1825-E/JQ is well-suited for battery-powered IoT sensor nodes thanks to its 1.8V-3.6V LF wide-voltage range and XLP technology delivering sub-uA sleep currents. The 12-bit ADC, 32kHz LFINTOSC, and mTouch peripherals enable periodic sensor sampling on wake-up events without external components. With 14KB Flash and 1KB RAM, the MCU can host a simple LoRa or sub-GHz driver alongside application logic. Designers should leverage the deep-sleep modes with RTCC wake-up to achieve multi-year coin-cell battery life in field deployments.
推薦
Capacitive Touch User Interface
The PIC16LF1825-E/JQ integrates Microchip's mTouch capacitive-sensing hardware and CVD front-end, making it ideal for button, slider, and proximity-sensing HMIs in appliances and consumer electronics. The 32MHz internal oscillator, 10-bit ADC, and 12 I/O pins let designers connect up to 12 touch electrodes without an external touch IC. Combined with XLP sleep, a wake-on-touch UI can extend battery life dramatically. Recommended PCB layout: keep ground pour around touch electrodes and route traces away from switching signals.
推薦
Wearable Health Monitor
For wearable health monitors, the PIC16LF1825-E/JQ offers the right balance of small UQFN-16 (4x4 mm) package size, low power, and 14KB Flash for sensor-fusion firmware. Its 12-bit ADC handles pulse-oximeter and temperature sensor inputs, while the EUSART/MSSP supports BLE module communication (e.g., RN4871). XLP modes enable nA-range sleep between samples, critical for fitness bands and medical patches. The exposed pad (EP) of the JQ package must be soldered for thermal and mechanical reliability on the flex PCB.
推薦
LED Lighting Controller
The PIC16LF1825-E/JQ can serve as a constant-current LED driver controller for smart-lighting products, using its 10-bit PWM modules to dim individual LED strings and the 12-bit ADC for closed-loop current sensing. The wide 1.8-3.6V LF range simplifies integration with battery-backed or USB-powered luminaires. mTouch inputs enable touch-capable lamps and dimmer panels. The EUSART enables wireless DMX or BLE control via a paired module. Designers should add FET gate drivers since the MCU I/O cannot directly drive high-current LED strings.
推薦
Small Home Appliance Control
For small home appliances such as coffee machines, blenders, fans, and humidifiers, the PIC16LF1825-E/JQ provides 14KB Flash for menu logic and 1KB RAM sufficient for sensor I/O buffering. The two PWM channels control motor speed or heater elements, while the ADC monitors temperature/level sensors. The extended -40C to +125C operating range supports under-hood and outdoor enclosures. The 32MHz internal oscillator eliminates the external crystal, BOM cost, and manufacturing steps.
推薦
Automotive Body Electronics Module
Although the PIC16LF1825-E/JQ itself is not AEC-Q100 qualified, the extended -40C to +125C 'E' temperature range and XLP low-power characteristics make it a candidate for non-safety automotive body modules such as ambient lighting, mirror controllers, or accessory interfaces. Its MSSP/I2C and EUSART interfaces connect to LIN transceivers or central body controllers. The UQFN-16 (JQ) package supports compact PCB layouts. Designers should verify AEC-Q100 requirements per project and select automotive-qualified variants where mandated.

主要差異化特點
- Largest Flash option in the PIC16LF182x UQFN-16 family (對比PIC16LF1824-E/JQ)
- Wide 1.8-3.6V LF operating range for battery-powered designs (對比PIC16F1825-E/JQ)
- Extended -40C to +125C temperature grade (E suffix) (對比PIC16LF1825-I/JQ)
設計說明
The 16-pin UQFN (JQ) package requires a properly sized exposed-pad (EP) land on the PCB, per the Microchip package specification. The EP must be soldered to a copper pad that connects to a low-impedance ground pour (typical 4-6 thermal vias to the inner/lower ground plane). This both provides mechanical reliability and a low thermal-resistance path for any pulsed loads. Estimated: with a typical 4-via EP land pattern, theta_JA is approximately 35-45 C/W.
For low-noise VDD supply, place a 0.1uF ceramic decoupling capacitor as close as possible to the VDD pin and a bulk 1-10uF capacitor within 5mm. The PIC16LF1825 has a separate AVDD reference for the ADC; if precision ADC readings are required, add a dedicated 10uH ferrite bead between VDD and AVDD plus a 0.1uF capacitor on AVDD. Keep ADC reference traces short and away from PWM and digital switching signals.
Common pitfalls: (1) leaving the MCLR pin floating - it must be tied high via a 10k resistor for normal operation, even if not used for reset. (2) configuring PICKit as the programmer but forgetting to disable low-voltage programming (LVP) in configuration bits if not desired. (3) drawing more than 50mA total from VDD/GND combined through bond wires - for higher loads, drive via external FETs. (4) Using the internal 32MHz oscillator without enabling the PLL config word when higher precision is required.
For I2C bus runs longer than 5cm, add external 2.2-4.7k pull-ups on SDA and SCL; the internal weak pull-ups (~50-100 kohm) are typically too weak for reliable 400 kHz Fast-mode I2C. For SPI signals above 8 MHz, route CLK/MOSI/MISO as a matched-length bus with a continuous ground reference underneath, and add a small (22-33 ohm) series resistor on the MCU CLK output to dampen ringing.
