PIC16LF15324T-I/JQ Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals into one package. Within Microchip's portfolio, 8-bit PIC16 MCUs occupy the mainstream low-power tier — they sit above 8-bit PIC10/PIC12 baseline controllers and below the 16-bit dsPIC® and 32-bit PIC32 families. The "LF" in PIC16LF15324 denotes the low-power F-variant silicon, optimized by the eXtreme Low-Power (XLP) technology for battery-operated and energy-harvesting products. The PIC16F15324 (5V capable) and PIC16LF15324 (1.8–3.6V) variants share the same peripherals and footprint, so designers typically migrate between them when supply or voltage requirements change.
Key features of the PIC16LF15324T-I/JQ include: 12 I/O pins, four 10-bit PWM outputs, a 10-bit ADC, a 5-bit DAC, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and two Enhanced USART modules supporting UART/SPI/I2C. The XLP technology provides nanoWatt sleep currents in the nA range and multiple low-power operating modes. On-chip peripherals such as the CLC and CWG allow glue logic and waveform synthesis without external components.
Architecturally, the device uses a RISC-based PIC16 core with a modified Harvard arrangement and a 14-bit instruction word, supported by Core Independent Peripherals (CIPs) that offload tasks from the CPU. This improves deterministic behaviour and reduces firmware complexity, which is critical in real-time control loops. With 32MHz operation at 3.3V, the core delivers roughly 8 MIPS of throughput.
Typical applications include IoT sensor nodes, consumer electronics, low-power wireless remote controls, LED lighting controllers, small motor control loops, battery-powered instruments, and Home Appliance subsystems. Designers frequently pair it with Microchip's MCP1700 LDO regulator and an MRF24J40 or RN2483 radio module for compact battery-fed sensor designs.
When designing with this MCU, remember that the 'T' suffix denotes Tape & Reel packaging, the 'I' suffix denotes the industrial temperature grade, and the '/JQ' suffix specifies the 16-UQFN 4x4mm package with an exposed thermal pad that must be soldered to the ground plane for thermal dissipation.

Aplicações típicas
PIC16LF15324T-I/JQ é adequado para 6 aplicaçãos: Battery-Powered IoT Sensor Node, LED Lighting Controller, Small Motor Control (Fan / Pump / DC Motor), Wearable Health Band / Fitness Tracker, Home Appliance User Interface / HMI, Industrial Sensor Transmitter (4-20 mA Loop / Wireless).
Battery-Powered IoT Sensor Node
The PIC16LF15324T-I/JQ is well suited to battery-powered IoT sensor nodes because it integrates 7 KB Flash, 512 B RAM, and the full XLP nanoWatt sleep peripheral set in a single 16-UQFN (4x4) package. Its 1.8-3.6 V supply matches single-cell Li-ion or 2xAA alkaline chemistries, while the four CLC cells and one CWG enable sensor timing and waveform synthesis without external glue logic. The two EUSART modules support UART, SPI and I2C to a sub-GHz radio such as the Microchip MRF89XA or to a low-energy BLE companion such as the RN4870. With sub-µA sleep current and peripheral module disable (PMD) registers, a typical duty-cycled sensor node achieves 3-5 year battery life on a single CR2032 coin cell. The 32 MHz core provides ample headroom for sensor calibration, oversampling and AES-friendly data framing in C.
Recomendado
LED Lighting Controller
The PIC16LF15324T-I/JQ drives multi-channel LED lighting controllers using its four 10-bit PWM outputs and 5-bit DAC for warm-white dimming. The Complementary Waveform Generator (CWG) provides hardware dead-band generation, making the part ideal for synchronous-buck LED driver topology where dead-time accuracy directly affects efficiency. Operating from 1.8 V to 3.6 V, the PIC can be powered directly from the same bus as low-voltage LED strings, reducing the need for a separate supply rail. The four Configurable Logic Cells (CLC) implement look-up-table-driven dimming curves and color mixing without CPU overhead, while the 10-bit ADC reads photo-sensors and current shunts for closed-loop luminous flux control. With 32 MHz instruction throughput, the MCU can refresh 8 PWM channels simultaneously and still respond to DMX-512 or DALI commands on the EUSART.
Recomendado
Small Motor Control (Fan / Pump / DC Motor)
For small brushed-DC motor or fan control, the PIC16LF15324T-I/JQ offers the necessary peripherals: four 10-bit PWMs, the Complementary Waveform Generator (CWG) for half-bridge control, two comparators for back-EMF sensing, and the 10-bit ADC for current measurement. The 32 MHz core (~8 MIPS) executes PI control loops at kHz rates with deterministic latency thanks to Core Independent Peripherals (CIPs) that offload timing from the CPU. The XLP technology means standby current is sub-µA, so the controller adds negligible quiescent drain when the motor is off. The 16-UQFN (4x4) package fits inside fan-inlet PCBs or pump housing caps. The 256-byte EEPROM stores calibration data, trim constants and usage counters.
Recomendado
Wearable Health Band / Fitness Tracker
The PIC16LF15324T-I/JQ is a fit for compact wearable bands thanks to its tiny 4x4 mm UQFN footprint, 1.8 V minimum supply (compatible with small Li-Po cells), and XLP low-power modes that drop the core into sub-µA sleep. With 7 KB Flash, the firmware can host a basic heart-rate algorithm and BLE radio control, while the 10-bit ADC reads PPG/photo-sensor analog signals and the two comparators handle threshold detection for fitness events. The two EUSART modules operate as UART or I2C to drive an OLED display and a temperature sensor such as the MCP9808. With 12 I/O pins, the device can scan a small capacitive-touch keypad through the CLC cells while the CPU is asleep.
Recomendado
Home Appliance User Interface / HMI
In home appliances — washing machines, dishwashers, coffee makers, microwave ovens — the PIC16LF15324T-I/JQ serves as the user-interface and HMI controller, multiplexing button inputs, driving 7-segment or small LCD displays, and providing a low-cost supervisory MCU between the appliance's main controller and its display. The 12 I/O pins drive up to 12 multiplexed keypad/LED rows, while the two EUSARTs talk to the main controller and to an external sensor expansion port. With 256 B EEPROM, the device stores user settings (wash cycle preferences, language, calibration values) across power cycles. The XLP low-power modes keep standby consumption below 100 µA, helping appliances meet Energy Star idle requirements.
Recomendado
Industrial Sensor Transmitter (4-20 mA Loop / Wireless)
The PIC16LF15324T-I/JQ is used in industrial sensor transmitters that digitize analog process signals and transmit them either as 4-20 mA current-loop output or as a wireless HART/WirelessHART packet. Its 10-bit ADC reads the bridge or 4-20 mA input, the 5-bit DAC generates the 4-20 mA output, and the two EUSARTs handle HART modulation/demodulation and serial diagnostics. The XLP low-power modes are critical here: loop-powered transmitters must run from the 4 mA minimum loop current, so the PIC plus its companion circuitry must consume well under 4 mA total. With 7 KB Flash and 512 B RAM, the firmware fits an IEC 61131-2 signal-conditioning library plus HART command processing.

Notas de projeto
The 16-UQFN (4x4 mm) package has a center exposed thermal pad on the bottom that MUST be soldered to the ground plane for both thermal dissipation and mechanical reliability. Microchip's land-pattern recommendation (per PIC16(L)F15324 datasheet DS40001891) calls for at least 4 thermal vias (0.3 mm diameter) in the pad array to conduct heat to internal copper layers. Skipping the EP soldering results in poor electrical ground reference and may cause the part to overheat at higher ambient temperatures.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 16) and a bulk 1 µF to 10 µF tantalum or ceramic capacitor on the same VDD node. For low-power designs using the XLP nanoWatt sleep mode, use a 1 µF or larger bulk capacitor on VDD to prevent sleep-mode wakeup glitches caused by switch-mode converter instability. The VDD voltage must remain between 1.8 V and 3.6 V at all times; voltage dips below 1.8 V during radio transmission can cause brown-out resets.
Do not connect an external pull-up to the ICSPCLK/ICSPDAT pins (RA0/RA1) during normal operation; these pins double as programming/debug interfaces and external pull-ups can interfere with the debugger. If RA0/RA1 are used as GPIO, configure them as digital outputs or high-impedance inputs only after disabling ICSP. Also note that RA3 is shared with VPP programming voltage; do not pull RA3 high during reset, or the device may enter programming mode unintentionally.
Keep the analog and digital ground planes separated by a single point of connection under the MCU's exposed pad. Route the ADC input traces away from PWM outputs and high-current switching traces to minimize digital-to-analog crosstalk. If the PCB has an on-board switching regulator (DC-DC buck or boost), place the PIC on the opposite side of the board with at least a 10 mm trace gap, and add a ferrite bead on the VDD supply near the PIC to filter switching ripple.
