PIC16F18325-E/JQ - 8-Bit 32MHz 14KB Flash MCU | Microchip
MPN： PIC16F18325-E/JQ ✓ 啟用中PIC16F18325-E/JQ 概覽
Key features include Peripheral Pin Select (PPS) which allows remapping of digital peripheral I/O to virtually any GPIO, drastically simplifying PCB layout. Communication is handled by EUSART, SPI, and I2C peripherals, while functional safety (FuSa) support and an extended -40C to +125C operating range qualify the part for industrial and high-temperature environments.
Architecturally the PIC16F18325 uses a 14-bit instruction word enhanced mid-range core with a hardware multiplier, 16-level hardware stack, and interrupt-driven event system. CLCs (Configurable Logic Cells) implement glue logic in hardware, the NCO provides precision frequency synthesis for LED dimming or tone generation, and the CWG delivers complementary waveforms with dead-band control for motor or power-converter drive.
Typical applications include IoT sensor nodes, low-power wireless remote controls, LED lighting controllers, small motor drives (fans, BLDC), battery chargers, and consumer appliances such as coffee machines or hand tools where the 4x4 mm package enables very compact PCBs.
When designing with this device, place the 0.1uF and 1uF decoupling capacitors as close as possible to VDD/AVDD/VBAT pins, use the PPS feature to avoid signal crossings on the PCB, and leverage the CLC/NCO to off-load timing-critical functions from the CPU. The unique /MCLR, ICD pins support in-circuit debug and ICSP programming.

典型應用
PIC16F18325-E/JQ 適用於 7 應用s: Battery-Powered IoT Sensor Node, LED Lighting Controller / Dimmer, Small Brushless DC Motor / Fan Drive, Remote Control / Wireless HMI, Industrial Sensor Transmitter (4-20 mA / 0-10 V), Consumer Appliance Control (Coffee Maker / Hand Tool), Automotive Body Electronics (Rear Lighting / Mirror Control).
Battery-Powered IoT Sensor Node
The PIC16F18325-E/JQ fits battery-powered IoT sensor nodes by combining XLP sleep currents in the sub-microamp range with 14 KB Flash for application code and 1 KB RAM for sensor buffers. Its 11-channel 10-bit ADC reads temperature, humidity, and analog sensors directly, and the 5-bit DACs handle calibration or analog output to external circuitry. The PPS feature lets the EUSART/SPI/I2C peripherals map to any GPIO, simplifying PCB routing in tiny 4x4 mm footprints.
推薦
LED Lighting Controller / Dimmer
The PIC16F18325-E/JQ is a strong fit for LED lighting controllers thanks to its NCO (Numerically Controlled Oscillator) for precise PWM-free dimming, CWG (Complementary Waveform Generator) for half-bridge LED driver timing, and 2x 10-bit PWM channels. With 32 MHz CPU, real-time color-mixing math executes without jitter, while the 256-byte EEPROM stores calibration and trim values. The 16-UQFN 4x4 mm package fits inside MR16 lamp form factors.
推薦
Small Brushless DC Motor / Fan Drive
For small BLDC fans and pumps, the PIC16F18325-E/JQ's CWG module generates complementary PWM with dead-band control, eliminating external gate-driver logic. The 9 timers and 2 comparators handle back-EMF sensing and zero-cross detection, while the 32 MHz core runs sensorless commutation algorithms in real time. The extended -40 C to +125 C grade supports under-hood automotive or industrial motor control environments.
推薦
Remote Control / Wireless HMI
The PIC16F18325-E/JQ fits IR/RF remote controls and small HMI panels because CLC cells implement custom keypad/IR encoder glue logic in hardware offloading the CPU. PPS allows SPI/I2C to drive LCD or OLED displays with flexible pin mapping, and the 5-bit DAC generates audio beeps or voice prompts. Sleep currents below 1 uA enable coin-cell operation for years of standby.
推薦
Industrial Sensor Transmitter (4-20 mA / 0-10 V)
The PIC16F18325-E/JQ powers industrial sensor transmitters (pressure, flow, level) because its 11-channel 10-bit ADC digitizes sensor bridges with adequate resolution, while the CLC/NCO peripherals generate precision excitation signals. The 256-byte EEPROM retains calibration coefficients across power cycles, and the extended temperature range (-40 C to +125 C) supports harsh plant-floor conditions. Industrial protocols (HART, IO-Link) can be implemented via the UART/SPI/I2C peripherals.
推薦
Consumer Appliance Control (Coffee Maker / Hand Tool)
In consumer appliances such as coffee machines, hand tools, or small kitchen devices, the PIC16F18325-E/JQ drives keypads, relays, and TRIACs via the CWG. The 32 MHz CPU runs user-interface state machines smoothly, while the 2x 5-bit DACs control analog setpoints (temperature, pressure). The 16-UQFN 4x4 mm footprint enables ultra-compact PCBs that fit inside tight enclosures.
推薦
Automotive Body Electronics (Rear Lighting / Mirror Control)
The PIC16F18325-E/JQ (E-grade, -40 C to +125 C) supports automotive body modules such as rear lamp drivers and mirror controllers. Its CWG generates precise LED-tail timing, the 2x comparators monitor current feedback, and LIN/EUSART enables communication with the vehicle bus. Functional safety (FuSa) support aids ASIL-classification efforts, and the small UQFN footprint fits behind mirror glass.

主要差異化特點
- Full Core Independent Peripherals (CLC/NCO/CWG) with PPS in a 16-pin UQFN (對比PIC16F1825-I/JQ)
- Extended -40 C to +125 C grade with FuSa support (對比PIC16F18325-I/JQ)
- 14 KB Flash vs ~10 KB on PIC18F legacy UQFN MCUs in the same footprint (對比PIC16F1823-E/JQ)
設計說明
Place a 100 nF decoupling capacitor and a 1 uF bulk capacitor as close as possible to the VDD pin (pin 16) and VSS (pin 7) on the 16-UQFN package. Solder the exposed thermal pad to a continuous ground pour to minimize thermal resistance and provide a low-impedance return path for high-frequency digital switching. Trace the VDD/VSS traces wide (>0.3 mm) to reduce parasitic inductance.
Do not skip configuration of the PPS (Peripheral Pin Select) registers - leaving PPS unlocked or mis-locked can prevent UART, SPI, I2C, or CLC outputs from reaching their assigned GPIOs and the device appears non-functional. Always unlock PPS by writing PPSLOCK = 0x55 then 0xAA before writing PPS registers, then re-lock to avoid accidental runtime re-mapping.
Estimated: At 32 MHz CPU and 5.5 V supply with all peripherals enabled, the PIC16F18325-E/JQ typically draws ~7 mA active, dissipating ~38 mW. With the 16-UQFN 4x4 mm exposed-pad package (theta_JA ~40 C/W typical), the junction temperature rise is ~1.5 C above ambient - well within the +125 C max. However, sustained 32 MHz operation at +85 C ambient should still verify EEPROM write endurance (100k cycles typical).
For SPI/I2C lines running above 1 MHz, add 4.7 kohm pull-ups on I2C and series 33 ohm resistors on SPI outputs near the MCU pin to dampen reflections. Use PPS to remap EUSART/SPI/I2C away from ADC-capable pins when those ADC channels must read low-impedance analog sources without digital crosstalk injection.
合規資訊
RoHS compliant per Microchip product page. E-grade (-40 C to +125 C) supports high-temperature operation but is not AEC-Q100 qualified; use VAO suffix (e.g. PIC16F18325-E/SLVAO) for AEC-Q100 automotive applications. Functional Safety (FuSa) features included but not a formal safety element out of accreditation - verify per ISO 26262 application requirements.
