PIC16F15324-I/JQ Overview
What is a PIC 8-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and peripherals on one die. The PIC16F family uses Microchip's enhanced mid-range core with 49 instructions, 16-level hardware stack, and Peripheral Pin Select (PPS) for flexible signal routing. Within the semiconductor taxonomy, an MCU sits under microcontroller -> embedded processor -> digital IC -> integrated circuit. The 8-bit data path prioritizes deterministic real-time response, low cost, and ultra-low standby current over raw arithmetic throughput.
Key features include a 10-bit ADC with up to 11 channels, a 5-bit DAC, two comparators, four 10-bit PWMs, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), two EUSART (LIN-capable) modules, and I2C/SPI peripherals. Brown-out Reset (BOR), Power-on Reset (POR), and Peripheral Module Disable (PMD) reduce active and sleep currents to nanoampere levels, enabling years of operation from a single coin cell.
Architecture-wise, the device pairs the enhanced mid-range core with hardware multiplier support, DMA-free CIP blocks, and PPS that remaps most digital peripherals to nearly any I/O pin. The internal 32 MHz oscillator eliminates the external crystal in cost-sensitive layouts while still allowing an external oscillator reference for timing-critical UART or LIN-bus stacks.
Typical applications include IoT sensor nodes, wearable health bands, battery-powered remote controls, LIN slave nodes in automotive body electronics, low-cost PWM fan or LED controllers, and small appliance user interfaces. The wide 1.8V-5.5V VDD range and XLP nanoWatt sleep modes directly address battery and energy-harvesting designs.
When designing with this device, always read the latest Microchip device datasheet and errata before committing layout. Place a 0.1 uF decoupling capacitor within 3 mm of VDD, keep analog AVSS/AVDD traces short, and leave at least one NC-tolerant pin free for PPS remapping flexibility.

Typical Applications
PIC16F15324-I/JQ is suitable for 7 applications: IoT Battery Sensor Node, Wearable Health Band, LIN Slave Automotive Body Electronics, Low-Cost PWM Fan / LED Controller, Small Appliance User Interface, Remote Control / IR Transmitter, Industrial Sensor Hub.
IoT Battery Sensor Node
The PIC16F15324-I/JQ is a strong fit for coin-cell-powered IoT sensor nodes. Its XLP nanoWatt sleep modes drop quiescent current below 100 nA, and the 7 KB Flash is sufficient for BLE host drivers plus sensor fusion code. The four Configurable Logic Cells (CLC) and Complementary Waveform Generator (CWG) let the part wake on a comparator threshold and emit a pulse train without waking the CPU, materially extending battery life.
Recommended
Wearable Health Band
For wearable health bands, the PIC16F15324-I/JQ delivers a 1.8-5.5 V VDD range, 4x4 mm UQFN-16 footprint, and the 10-bit ADC plus 5-bit DAC needed for optical heart-rate and temperature front-ends. The two comparators support low-power analog signal conditioning while the CLCs handle event sequencing in deep sleep, allowing a single CR2032 cell to power the device for months of continuous wear.
Recommended
LIN Slave Automotive Body Electronics
In LIN-bus automotive body modules such as window lift, seat control, and ambient lighting, the PIC16F15324-I/JQ's two EUSARTs implement LIN 2.x slave with the Microchip LIN stack. The 32 MHz HFINTOSC gives clean baud-rate generation, while XLP sleep current (under 100 nA) and the wide -40 C to +85 C industrial operating range match body-electronics quiescent-drain budgets.
Recommended
Low-Cost PWM Fan / LED Controller
The PIC16F15324-I/JQ integrates four 10-bit PWMs and a Complementary Waveform Generator (CWG) suited to small DC fan speed controllers and RGB LED drivers. The 32 MHz core gives PWM resolution below 1% duty cycle at 25 kHz, while the 1.8-5.5 V VDD range allows direct drive from a single Li-ion cell, eliminating the need for a separate 5 V rail.
Recommended
Small Appliance User Interface
For white-goods HMI panels and small-appliance controls, the PIC16F15324-I/JQ combines enough Flash (7 KB) for state-machine plus display drivers, CLC-based capacitive touch via the comparators, and the PPS feature that lets designers remap I/O around PCB constraints. Its small UQFN-16 footprint simplifies layout in space-constrained front-panel PCBs.
Recommended
Remote Control / IR Transmitter
The PIC16F15324-I/JQ's XLP sleep current, Peripheral Module Disable (PMD), and CWG block make it ideal for infrared remote controls. The CWG can synthesize the 38 kHz carrier entirely in hardware, waking the CPU only when a key press occurs. The 7 KB Flash accommodates multiple protocol stacks (RC5, NEC, SIRC), and the 1.8 V minimum VDD allows direct 2xAAA battery operation.
Recommended
Industrial Sensor Hub
The PIC16F15324-I/JQ serves as a low-cost sensor hub for industrial 4-20 mA loop or 0-10 V analog front-ends. The 10-bit ADC with 11 channels and two comparators deliver multi-input digitization, and the two EUSARTs bridge to RS-485 transceivers for factory-floor networking. Industrial-temperature (-40 C to +85 C) operation is supported by the I-grade variant.

Key Differentiators
- More Flash than F15323 in the same UQFN-16 footprint (vs PIC16F15323-I/JQ)
- Adds Core Independent Peripherals (CLC and CWG) (vs PIC16F1455-I/JQ)
- Wider 1.8 V minimum VDD vs F1455 2.3 V (vs PIC16F1455-I/JQ)
Design Notes
Place a 0.1 uF decoupling capacitor within 3 mm of the VDD pin and a bulk capacitor (1-10 uF) on the same net. The PIC16F15324-I/JQ's BOR and POR thresholds are configured in configuration words; selecting BOR_LOW can drop minimum VDD to 1.8 V for single-cell Li-ion or 2xAA designs. Always enable the internal voltage regulator by tying VDD to the same rail as the MCU core. Estimated: with all peripherals disabled and the part in sleep, quiescent current drops below 100 nA per Microchip XLP datasheet figures.
Solder the UQFN-16 exposed thermal pad (EP) to a continuous ground plane with at least 8 thermal vias to the inner ground layer. This both dissipates ~200 mW and provides mechanical solder-joint reliability. Keep analog (AVDD/AVSS) traces short and isolated from switching PWM traces; route PPS-mapped signals with matched length when used as EUSART or SPI. The Device Data Sheet recommends 0.25 mm trace width with 0.15 mm clearance for the UQFN-16 land pattern.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm pull-up and a 100 nF cap to ground to avoid spurious resets. Always read the device errata sheet before firmware freeze: some PIC16F15324-I/JQ revisions have ADC and CLC behavior issues fixed in later silicon. The PPS feature can remap most peripherals but cannot change analog pin assignments - keep your analog inputs on dedicated ANx pins. Estimated: enabling all peripherals simultaneously can push IDD above 4 mA at 32 MHz; use PMD to disable unused blocks.
Compliance Information
RoHS compliant per Microchip product page. For AEC-Q100 qualified automotive variants, see the PIC16F15324T-E/SLVAO or PIC16F15324T-E/STVAO ordering codes (same die, automotive qualification).
