PIC16LF15324-E/ST 概要
What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a small computer-on-a-chip with an 8-bit data path, on-board program memory (Flash), RAM, and integrated peripherals such as timers, ADCs, and communication interfaces. MCUs sit within the broader semiconductor hierarchy of embedded computing devices, between simple logic ICs and more complex 32-bit microprocessors, and serve as the brain of embedded systems. The PIC16LF15324-E/ST belongs to the PIC microcontroller family -> 8-bit MCU -> microcontroller -> embedded computing -> semiconductor taxonomy.
Key features of this device include a 10-bit ADC with computation, a 5-bit DAC, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), four 10-bit PWMs, and dual EUSART, SPI, and I2C communication interfaces. The device operates from 1.8V to 3.6V, making it suitable for battery-powered applications. The integrated 32 MHz internal oscillator eliminates the need for an external crystal in many designs, reducing BOM cost and board space.
Architecturally, the PIC16LF15324-E/ST employs a modified Harvard RISC core with a 14-bit instruction word, providing deterministic interrupt response and efficient code density. The XLP features include a typical sleep current under 1 µA with peripheral activity, enabling years of operation from a single coin cell. The Core Independent Peripherals (CLC, CWG, NCO) operate without CPU intervention, freeing the core for application logic and reducing firmware complexity.
Typical applications include low-power IoT sensor nodes, battery-powered consumer electronics, home automation controllers, LED lighting control, automotive body electronics (non-safety), and small appliances. The combination of rich peripherals and tiny package makes it ideal for space-constrained designs requiring multiple communication interfaces.
When designing with this MCU, ensure decoupling capacitors (typically 100 nF and 10 µF) are placed close to VDD, and follow Microchip's MPLAB X IDE and XC8 compiler toolchain for firmware development. The ICSP programming interface uses dedicated pins; route them to a connector or test pad for in-circuit programming.

主な用途
PIC16LF15324-E/ST の用途: 6 件s: Battery-Powered IoT Sensor Node, Home Automation Controller, LED Lighting Control, Small Appliance Control Board, Automotive Body Electronics (Non-Safety), Wearable Health Monitor (Low-Power).
Battery-Powered IoT Sensor Node
The PIC16LF15324-E/ST is well-suited for battery-powered IoT sensor nodes because of its 1.8 V to 3.6 V supply range and eXtreme Low Power (XLP) technology, which delivers sleep currents below 1 µA. Its 32 MHz core provides enough processing throughput to handle periodic sensor reads, local filtering, and I2C communication with environmental sensors. The 7 KB Flash supports small protocol stacks (e.g., Modbus or lightweight MQTT-SN) while the integrated 10-bit ADC with computation performs autonomous sensor sampling without waking the CPU. Placed between a 3 V coin cell and the sensor cluster, it enables multi-year battery life. Compared to a discrete RTC + sensor frontend design, integrating the comparator, DAC, and CLC peripherals onto one chip reduces BOM cost by approximately 30 percent.
おすすめ
Home Automation Controller
For home automation controllers (lighting, blinds, HVAC keypads), the PIC16LF15324-E/ST provides the right balance of peripherals and power: dual EUSART enables simultaneous communication with a wireless module and a wired RS-485 backbone, while the four 10-bit PWMs drive LED dimming or small motor control. The Complementary Waveform Generator (CWG) supports half-bridge driver signals for FET-based relay or solenoid switching without additional timing hardware. Its 14-pin TSSOP package fits inside standard wall-switch back boxes. The wide 1.8 V to 3.6 V range simplifies integration with 3.3 V wireless modules like the RN2483 or ESP32 coprocessors. Integrated CLC blocks can implement custom glue logic to debounce mechanical switches in hardware, offloading the CPU.
おすすめ
LED Lighting Control
In LED lighting control applications, the PIC16LF15324-E/ST drives up to four PWM channels independently, enabling tunable white or RGB LED strips with smooth dimming. Its 32 MHz core provides sufficient resolution (about 8-bit effective PWM at 32 kHz) for flicker-free dimming per the NEMA SSL 7A standard. The integrated 5-bit DAC and two comparators allow closed-loop current sensing without external op-amps, while the 10-bit ADC monitors LED temperature for thermal foldback protection. Operating from 3.3 V, the MCU pairs directly with constant-current LED drivers such as the TLC5941 or STP16CP05. The TSSOP-14 package is small enough for in-fixture integration. Sleep current under 1 µA lets standby lighting fixtures meet ENERGY STAR standby requirements.
おすすめ
Small Appliance Control Board
The PIC16LF15324-E/ST fits small appliance control boards (coffee makers, blenders, air purifiers) because it combines a wide-voltage MCU core with motor-control-friendly peripherals. The Complementary Waveform Generator (CWG) generates complementary PWM signals for driving a half-bridge or full-bridge motor power stage with built-in dead-band control. Its four 10-bit PWM channels can independently control heating elements, fan speeds, and indicator LEDs. The 14-pin TSSOP footprint allows single-sided PCB assembly to meet aggressive BOM cost targets in consumer appliances. The -40 °C to +125 °C extended temperature range handles under-cabinet or garage environments. EUSART plus I2C support enables connectivity to HMI displays and BLE modules for smart-appliance variants.
おすすめ
Automotive Body Electronics (Non-Safety)
For non-safety automotive body electronics (interior lighting, seat controllers, mirror adjusters, accessory modules), the PIC16LF15324-E/ST's -40 °C to +125 °C extended temperature range and 14-pin TSSOP package suit space-constrained body controllers. However, this part is NOT AEC-Q100 qualified - for safety-relevant or AEC-Q100-mandated designs, use the automotive-graded PIC16F15324-E/ST (which shares the same die but with automotive qualification). The LF variant operates from 1.8 V to 3.6 V, well-suited to 3.3 V-regulated body domains. The integrated EUSART and LIN-capable software stacks enable body-domain communication via LIN bus transceivers like the MCP2003B.
おすすめ
Wearable Health Monitor (Low-Power)
The PIC16LF15324-E/ST suits wearable health monitors such as fitness bands, pulse oximeters, and continuous glucose monitors because of its XLP technology and 1.8 V to 3.6 V operating range that pairs directly with single-cell Li-ion batteries. Its 32 MHz core executes signal-processing routines for heart-rate and SpO2 algorithms, while the integrated 10-bit ADC with computation performs oversampling and averaging without external components. Sleep mode draws under 1 µA, enabling weeks of standby between charges. The 14-pin TSSOP package fits inside wristband enclosures under 8 mm thick. Dual EUSART enables simultaneous BLE communication and accessory sensor data logging, while the comparator triggers immediate wakeup from sleep on user button press or motion event.

設計ノート
Estimated: total power budget at 32 MHz active mode draws approximately 5 mA at 3.3 V (about 16.5 mW). For battery life calculations, the dominant factor is duty cycle: a sensor node waking every 10 seconds for 50 ms draws average current of (50ms × 5mA + 9950ms × 1µA) / 10s = 25 µA average. From a 1000 mAh coin cell, this delivers approximately 4.6 years of operation. Always place a 100 nF decoupling capacitor within 5 mm of VDD pin 1, plus a bulk 10 µF tantalum or ceramic capacitor to handle transient current demands during peripheral activation.
Route the ICSP programming pins (RA0/ICSPDAT pin 7, RA1/ICSPCLK pin 6) to a 2x3 or 1x6 header accessible from the board edge. The MCLR/RA3 pin (pin 4) requires a 10 kΩ pull-up to VDD; do not leave it floating or the device will randomly reset. Keep the VDD trace wide (≥0.5 mm) and place the decoupling capacitor directly at the IC's VDD lead. For TSSOP-14, expose a small ground plane under the IC to provide thermal sinking and a low-impedance return path.
Do not apply voltages above 3.6 V to any pin of the PIC16LF15324-E/ST, including I/O pins, even momentarily during power-up transients - this will cause latch-up. Use a reset supervisory IC like MCP131 or a TVS diode on VDD if the system shares a 5 V rail. The LF (low-voltage) variant cannot be substituted for F-variant in 5 V designs. Always configure unused I/O pins as outputs driving low to minimize sleep current. Verify oscillator configuration bits match the application; the internal 32 MHz oscillator eliminates the need for external crystals but requires the correct configuration word settings.
