PIC16F15323-I/SL 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash, RAM, EEPROM), and programmable peripherals into one IC. The PIC16F15323 belongs to the 8-bit enhanced mid-range MCU hierarchy, which sits between Microchip's baseline 8-bit cores and 16-bit PIC24/dsPIC families. Its peripheral pin select (PPS) and peripheral module disable (PMD) features allow flexible pin mapping and fine-grained power gating, while eXtreme Low Power (XLP) IDLE and DOZE modes help designers minimize active and standby current for battery-powered applications.
Key features of the PIC16F15323 include eXtreme Low Power (XLP) technology for sub-microamp sleep currents, 4x 10-bit PWM outputs, 2x comparators with selectable references, a 5-bit DAC, 4x Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), EUSART (enhanced USART), SPI, I2C, and a 10-bit ADC. The device supports self-read/write Flash with a wide 2.3V to 5.5V operating voltage, making it suitable for both 3.3V and 5V systems. The PIC16F15323 also supports in-circuit serial programming (ICSP) and debugging.
The PIC16F15323 uses a Harvard architecture with separate program and data buses, an internal oscillator accurate to ±1% typical, and a low-power 32 kHz secondary oscillator for RTC-like functions. This architecture enables deterministic instruction execution and rapid interrupt response, both of which are valuable in real-time control loops such as LED dimming, motor commutation, and sensor signal conditioning. Combined with 4 CLC blocks, designers can implement custom combinational and sequential logic in hardware without external glue chips.
Typical applications include low-power IoT sensor nodes, LED lighting and signage controllers, battery-powered consumer devices, automotive body and accessory modules (where AEC-Q100 is not required), small home appliances, and general-purpose digital control replacing discrete logic. The combination of analog peripherals (ADC, DAC, comparator) and communication peripherals (EUSART, SPI, I2C) makes it a flexible system-on-chip for cost-sensitive embedded designs.
When designing with this device, ensure that the internal oscillator accuracy is acceptable for your UART timing budget; otherwise, an external crystal or resonator may be required. Use Microchip's MPLAB X IDE and XC8 compiler for firmware development, and configure unused pins as digital low-power outputs to minimize current draw in sleep modes.

主な用途
PIC16F15323-I/SL の用途: 6 件s: Battery-Powered IoT Sensor Node, LED Lighting and Signage Controller, Small Home Appliance Control, Sensor Signal Conditioning Front-End, User Interface and HMI Replacement Logic, Industrial Sensor and Actuator Module.
Battery-Powered IoT Sensor Node
The PIC16F15323-I/SL suits low-duty-cycle IoT sensor nodes because its eXtreme Low Power (XLP) IDLE and DOZE modes drop sleep current into the sub-microamp range while the 32 MHz core wakes quickly to process sensor data. The 10-bit ADC samples analog sensors, the EUSART or I2C block streams results to a host radio, and the 4 CLC blocks implement custom wake-up logic without external gates. With 3.5 KB Flash and 256 B SRAM, it fits typical sensor-firmware stacks while operating from a single 3.3 V coin cell or Li-ion source. Designers can use PPS to remap peripherals and minimize PCB trace length.
おすすめ
LED Lighting and Signage Controller
For LED driving, the PIC16F15323-I/SL provides 4x 10-bit PWM channels and a Complementary Waveform Generator (CWG) that produces dead-band-controlled complementary outputs suited to FET half-bridges. The 5-bit DAC and comparators implement closed-loop current regulation for constant-current LED strings, while the 32 MHz core runs color-mixing and dimming algorithms in real time. PPS allows PWM signals to be routed to any available I/O pin, simplifying PCB layout for multi-channel fixtures. The wide 2.3V to 5.5V supply range lets the same firmware serve 3.3V and 5V LED drivers.
おすすめ
Small Home Appliance Control
In small home appliances such as coffee makers, fans, humidifiers, and toasters, the PIC16F15323-I/SL acts as a single-chip controller handling keypad input, LED or seven-segment display output, temperature sensing via the 10-bit ADC, and triac/MOSFET driving through its PWM and CWG peripherals. With 49 instructions and 16 stack levels, the Enhanced Mid-Range core executes state machines efficiently, while PMD gates unused peripherals to keep standby current low. The 14-pin SOIC package fits crowded appliance PCBs and supports automated SMT assembly for high-volume production.
おすすめ
Sensor Signal Conditioning Front-End
The PIC16F15323-I/SL integrates a 10-bit ADC, two comparators, and a 5-bit DAC to perform complete analog front-end conditioning in a single IC. The comparators can generate interrupts on threshold crossings, the DAC provides programmable bias or threshold levels, and the CLC blocks combine comparator outputs with PWM signals to synthesize custom timing logic. With 32 MHz MIPS performance, the device can oversample and digitally filter signals before forwarding via SPI or UART, replacing several discrete op-amp and timer ICs in cost-sensitive designs.
おすすめ
User Interface and HMI Replacement Logic
When designs need to replace discrete 74HC logic with a programmable controller, the PIC16F15323-I/SL's 4 CLC blocks implement combinational and sequential logic in hardware while the CPU handles button debouncing, LED control, and serial commands. The EUSART block plus PWM outputs manage RGB LEDs or character displays, and PMD powers down unused peripherals for clean sleep behavior. The 12 I/O pins comfortably drive 4x4 keypads, multiple indicator LEDs, and one communication interface in a compact SOIC-14 footprint.
おすすめ
Industrial Sensor and Actuator Module
The PIC16F15323-I/SL operates across the industrial -40 C to +85 C range and tolerates 5 V supply rails typical in industrial control cabinets. The EUSART plus RS-485 transceiver support, combined with 10-bit ADC for 4-20 mA loop sensing, suits distributed sensor modules; PWM and CWG outputs can drive proportional valves or solid-state relays. PPS allows designers to place analog inputs away from switching outputs, simplifying PCB layout and reducing noise coupling in mixed-signal industrial environments.

設計ノート
Estimated: with all peripherals disabled and the CPU in SLEEP, the PIC16F15323-I/SL draws typically under 1 microamp from a 3.3 V supply, per the Microchip XLP datasheet curves. To achieve this, disable all unused peripherals via the PMD register, configure unused I/O pins as outputs driving low, and avoid floating analog inputs (tie unused analog pins to VSS or VDD through 10 kohm resistors). Use IDLE mode when periodic ADC sampling is required without CPU wake-up overhead.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 14) and a 10 uF bulk capacitor at the board power-entry point. Keep analog input traces short and away from PWM or CWG switching outputs to minimize coupling; the PPS feature lets you remap digital peripherals to I/O pins that are physically distant from sensitive analog nets. Add a ground pour under the SOIC-14 footprint to reduce return-path impedance.
Do not exceed the 32 MHz maximum CPU clock when VDD is below 3.0 V - the device specification reduces instruction rate at lower voltages. MCLR (pin 1 on this package, shared with RA3) must be pulled high for normal operation; a floating MCLR can cause intermittent resets. Configure the MCLR function via the CONFIG register if you need RA3 as a digital input. Also enable the watchdog timer in safety-critical designs.
