PIC16F15325-I/JQ 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, volatile working memory, and a rich set of peripheral interfaces. Within the broader semiconductor taxonomy, the PIC16F15325 belongs to the 8-bit MCU family (PIC16 -> 8-bit PIC -> Microcontroller -> Embedded Processing -> Semiconductor). The 'F' denotes Flash program memory, '15325' identifies the specific family member, 'I' indicates the industrial temperature grade (-40C to +85C), and '/JQ' specifies the 16-pin UQFN package.
Key differentiating features include the Core Independent Peripherals (CLC, CWG, NCO) that operate without CPU intervention, reducing firmware complexity and power consumption. The device also incorporates Peripheral Pin Select (PPS) for flexible signal routing, a Memory Access Partition (MAP) feature for data protection, and a 32MHz internal oscillator. The XLP technology enables ultra-low-power sleep currents suitable for battery-powered applications.
The PIC16F15325 uses an enhanced mid-range 8-bit PIC CPU core with a 14-bit instruction word and hardware stack, providing deterministic interrupt response and code density advantages. The integrated 32MHz oscillator, 10-bit ADC with up to 11 channels, and configurable logic cells allow analog and digital signal processing without external components. The MAP feature lets developers partition Flash into bootloader and application regions, supporting secure firmware updates.
Typical applications include IoT sensor nodes, battery-powered remote controls, low-power wireless modules, LED lighting controllers, HVAC environmental sensors, and consumer appliances. The combination of small package (UQFN-16), low power consumption, and rich peripheral integration makes it suitable for space-constrained, energy-efficient designs.
When designing with this MCU, ensure that the UQFN exposed pad is properly soldered to the ground plane for thermal dissipation and electrical performance. Programming via ICSP requires specific pin assignments that should be reserved in the PCB layout. The PPS feature allows pin function reassignment, simplifying PCB routing but requires firmware configuration.

主な用途
PIC16F15325-I/JQ の用途: 7 件s: Battery-Powered IoT Sensor Node, LED Lighting Controller, Home Appliance Control Board, Remote Control and HMI Keypad, HVAC Environmental Sensor Module, Consumer Toy and Hobby Electronics, Industrial Sensor Transmitter.
Battery-Powered IoT Sensor Node
The PIC16F15325-I/JQ fits battery-powered IoT sensor nodes because its XLP technology delivers nanoampere-range sleep currents while Core Independent Peripherals (CLC, CWG, timers) handle wake-up events without CPU intervention. With 14KB Flash and 1KB RAM it can run small RTOS-lite or bare-metal firmware for periodic sensor reads. The 10-bit ADC measures analog sensors and the 2xEUSART/SPI/I2C peripherals connect radios and sensors. Placed on a small PCB with a coin-cell battery and a sub-GHz or BLE module, the MCU achieves years of battery life.
おすすめ
LED Lighting Controller
The PIC16F15325-I/JQ is well-suited for LED lighting controllers thanks to its 4xPWM outputs and Complementary Waveform Generator (CWG) that produces dead-band-controlled complementary outputs for half-bridge LED driver stages. The 32MHz CPU executes color-mixing and dimming algorithms in real time while the CLC combines PWM signals for hardware-driven effects. With 14KB Flash the firmware fits smooth-fade, color-temperature, and remote-control logic. The UQFN-16 package fits compact MR16 bulb form factors.
おすすめ
Home Appliance Control Board
The PIC16F15325-I/JQ fits home appliance control boards (washing machines, dishwashers, coffee makers) due to its rich peripheral mix: 10-bit ADC reads temperature/level sensors, 4xPWM drives motor/solenoid loads, 2xEUSART interfaces with displays and inverter modules, and the CWG generates dead-band-controlled signals. The 14KB Flash supports user-interface state machines and fault handling. The industrial temperature grade (-40C to +85C) tolerates appliance thermal environments.
おすすめ
Remote Control and HMI Keypad
The PIC16F15325-I/JQ is ideal for remote controls and HMI keypads because its XLP technology delivers multi-year battery life while the 4xCLC cells debounce and decode key matrix inputs in hardware without waking the CPU. The 2xEUSART/SPI/I2C interface connects RF or BLE companion chips. With 1KB RAM and 14KB Flash it stores IR/RF protocol libraries and user settings. The UQFN-16 package (4x4mm) fits slim handheld enclosures.
おすすめ
HVAC Environmental Sensor Module
The PIC16F15325-I/JQ works well in HVAC environmental sensor modules measuring temperature, humidity, and air quality. The 10-bit ADC reads multiple analog sensors simultaneously while the I2C/SPI interfaces communicate with digital sensors. The 14KB Flash supports averaging/compensation algorithms and MODBUS or BACnet protocol stacks. The CLC handles hardware-level alarm thresholds without CPU wakeup, maximizing battery life in wireless sensor installations.
おすすめ
Consumer Toy and Hobby Electronics
The PIC16F15325-I/JQ fits consumer toy and hobby applications due to its low cost (~$1.42 at qty-1), small UQFN-16 footprint, and rich peripherals including 4xPWM (servo/motor control), 2xEUSART (controller interconnect), and ADC (battery monitoring). The CLC and CWG produce complex waveforms for sound effects or motor commutation without CPU load. The 14KB Flash supports feature-rich toy firmware while industrial temperature grade ensures reliability across indoor environments.
おすすめ
Industrial Sensor Transmitter
The PIC16F15325-I/JQ suits industrial 4-20mA loop-powered sensor transmitters where the XLP low sleep currents extend battery life in field deployments. The 10-bit ADC with PGA amplifies bridge sensor signals (pressure, strain) while the integrated 5-bit DAC calibrates loop current. The 2xEUSART supports HART or MODBUS protocol layers over RS-485. The industrial temperature grade and Memory Access Partition (MAP) feature enable secure field firmware updates over the same loop.

設計ノート
Estimated thermal analysis: the 16-pin UQFN (4x4 mm) package has an exposed thermal pad that MUST be soldered to a PCB copper pad for proper thermal and electrical performance. Recommended copper pad area is at least 16 mm^2 with multiple thermal vias (0.3 mm drill) connecting to an inner ground plane. Per Microchip datasheet DS40001865B, an unsoldered exposed pad increases thermal resistance by 3-5x and may cause reliability issues at high ambient temperatures.
Reserve ICSP programming pins (typically RA0/ICSPCLK and RA1/ICSPDAT, but pin-selectable via PPS) on the PCB layout for production programming. Add a 6-pin header footprint or test pads to enable in-system programming. Decoupling capacitors: place a 100 nF ceramic between VDD and VSS as close to the MCU pins as possible (under 5 mm trace length). Add a bulk capacitor (1-10 uF) at the board power entry.
For XLP low-power applications, configure unused peripherals as OFF (default after reset) and set I/O pins to digital low-impedance output with no load. Use the deep-sleep mode (DS) or full-power-down mode with CLC/timer wake-up sources. According to Microchip datasheet DS40001865B, sleep currents in DS mode with CLC active are in the nanoampere range - critical for battery life in IoT sensor nodes.
Common design pitfalls: (1) Do not exceed VDD max of 3.6V for the F-variant - use the LF-variant (PIC16LF15325) for 1.8V-only designs; (2) PPS reassignment requires unlocking the PPS registers in firmware before configuration writes; (4) The 32MHz internal oscillator has a factory calibration stored in Flash - do not erase the calibration area or HFINTOSC frequency accuracy degrades.
コンプライアンス情報
RoHS compliant per Microchip product page (Microchip has a corporate RoHS/REACH compliance program). For automotive AEC-Q100 qualification, choose PIC16F15324T-I/7NVAO (VAO suffix) instead of standard I/JQ. The -I/JQ suffix indicates industrial temperature grade only.
