PIC16F15323-I/JQ Overview
An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and a mix of analog and digital peripherals around a single 8-bit data bus. Within the broader taxonomy, the PIC16F15323 belongs to the 8-bit PIC MCU family -> enhanced mid-range core -> low-power XLP sub-family -> intelligent analog and Core Independent Peripherals (CIPs) branch -> semiconductor. The CIP philosophy places tasks like waveform generation, signal conditioning, and communication in hardware blocks so the CPU can remain in sleep, dramatically cutting system power.
Key features of the PIC16F15323-I/JQ include four 10-bit PWMs, a 5-bit and 10-bit DAC, a comparator, an ADC with acquisition logic, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), an EUSART, and SPI/I2C peripherals. The device supports Peripheral Pin Select (PPS), which allows most digital I/O to be remapped to a wide range of physical pins - greatly easing PCB layout when signal routing conflicts arise.
The IC uses a CMOS process with eXtreme Low Power (XLP) technology, providing IDLE and DOZE power-saving modes plus Peripheral Module Disable (PMD) to shut down unused peripherals. The device operates from 2.3 V to 5.5 V, supports both 3.3 V and 5 V rails, and is offered in industrial -40 C to +85 C temperature grade per the -I suffix. The UQFN-16 (JQ) exposed-pad package gives a compact 4x4 mm footprint suitable for space-constrained designs and aids thermal dissipation through the bottom pad.
Typical applications include low-power IoT sensor nodes, consumer appliances with HMI control, battery-powered handheld instruments, LED lighting controllers using the CWG, and general-purpose logic replacement using the CLC blocks. The combination of small footprint, integrated intelligent analog, and XLP modes also suits remote controls, toys, and wearables.
When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to the VDD pin and tie the exposed thermal pad (EP) to a solid ground plane for electrical and thermal performance. Use PPS early in the schematic phase to lock pin assignments before laying out the PCB, since reassigning peripherals later may force a re-spin.

Typical Applications
PIC16F15323-I/JQ is suitable for 6 applications: Low-Power IoT Sensor Node, Consumer Appliance HMI Controller, LED Lighting Controller with CWG, Battery-Powered Handheld Instrument, General-Purpose CLC Logic Replacement, Remote Control and Toy Electronics.
Low-Power IoT Sensor Node
The PIC16F15323-I/JQ is well-suited for battery-powered IoT sensor nodes because its eXtreme Low Power (XLP) sleep current drops into the nanoampere range with most peripherals disabled via Peripheral Module Disable (PMD), and the 4x Configurable Logic Cells (CLC) can wake the device on external events without waking the CPU. The 10-bit ADC and 5/10-bit DAC provide local analog signal conditioning for sensors, while the integrated EUSART/SPI/I2C peripherals allow direct connection to radios like the MRF24XA or external LoRa modules. With 3.5 KB Flash and 256 B RAM, firmware fits small state-machine-based sensor stacks rather than full RTOS environments. The 2.3-5.5 V supply window allows direct connection to a single-cell Li-ion or 2xAA battery stack, and the 16-pin UQFN footprint fits inside sub-1 cubic-inch sensor housings.
Recommended
Consumer Appliance HMI Controller
For appliance front-panel HMI controllers (coffee machines, microwaves, washing machines), the PIC16F15323-I/JQ delivers the right peripheral mix at the right cost. The 4x 10-bit PWMs drive LED backlights, indicators, and buzzers; the CLC cells implement custom logic for key-matrix scanning or capacitive-touch decoding without CPU intervention; and the Complementary Waveform Generator (CWG) generates half-bridge drives for small solenoids or buzzer piezoelectric elements. With Peripheral Pin Select (PPS), PCB layout flexibility simplifies routing of button arrays and display signals. The 32 MHz/8 MIPS performance comfortably runs segmented LCD or LED display multiplexing state machines, while the industrial -40 C to +85 C temperature rating covers indoor appliance environments.
Recommended
LED Lighting Controller with CWG
The PIC16F15323-I/JQ's Complementary Waveform Generator (CWG) is purpose-built for LED lighting applications: it derives complementary PWM outputs with programmable dead-band control, enabling direct drive of half-bridge MOSFET stages without external gate-driver logic. Combined with the 4x 10-bit PWMs for dimming and color-mixing, the device can implement RGBW or tunable-white LED drivers in a single IC. The 5/10-bit DAC provides analog reference for current-sense setpoints. Peripheral Pin Select allows flexible routing of PWM outputs to any I/O pin, easing PCB layout when the LED string footprints are constrained. The wide 2.3-5.5 V supply accommodates both 3.3 V logic and 5 V analog reference rails in the same design.
Recommended
Battery-Powered Handheld Instrument
Handheld instruments like digital multimeters, thermal cameras, and pocket oscilloscopes benefit from the PIC16F15323-I/JQ's combination of analog integration and small footprint. The 10-bit ADC with acquisition logic handles sensor front-ends; the comparator supports threshold detection; the CLC blocks implement hardware debouncing and frequency measurement; and the PWM modules drive LCD bias or speaker tones. With 256 B SRAM and 3.5 KB Flash, the device runs small control loops and communication stacks (EUSART for UART-USB bridges via MCP2200). XLP technology with IDLE/DOZE modes extends battery life significantly between user interactions. The UQFN-16 4x4 mm package fits inside cramped handheld enclosures while the exposed pad handles modest thermal dissipation.
Recommended
General-Purpose CLC Logic Replacement
The 4x Configurable Logic Cells (CLC) on the PIC16F15323-I/JQ allow it to replace discrete logic gates, flip-flops, and simple state machines, reducing PCB area and BOM cost. Engineers can configure each CLC as AND/OR/XOR/D-Flip-Flop/JK or other primitives and interconnect them to peripherals like the PWM, comparator, and CWG outputs. This makes the device an excellent choice for glue-logic replacement in industrial control boards, sensor signal conditioning, or protocol bridging front-ends. The PPS feature then routes these CLC outputs to any I/O pin, eliminating the routing constraints that plague fixed-pin logic ICs.
Recommended
Remote Control and Toy Electronics
The PIC16F15323-I/JQ fits cost-sensitive remote control and toy applications that still demand modern features. The 4x PWMs drive vibration motors, RGB LEDs, and IR emitters; the EUSART handles IR protocol encoding for universal remote functions; the CLC cells debounce buttons without CPU load; and the CWG generates complementary drive for small DC motor H-bridges. The industrial -40 C to +85 C temperature range handles indoor and outdoor toy environments, while the UQFN-16 4x4 mm package fits inside slim remote housings. Distributor pricing below $1 at 1000-piece quantities makes this part economically attractive for high-volume consumer products.

Key Differentiators
- Higher density of Core Independent Peripherals than the older PIC16F1455-I/JQ (vs PIC16F1455-I/JQ)
- Smaller pin count than PIC16F15323-E/SL while retaining full peripheral set (vs PIC16F15323-E/SL)
- Native UQFN-16 (JQ) footprint with exposed pad (vs PIC16F15313-I/P)
Design Notes
Place a 0.1 uF decoupling capacitor as close as physically possible to the VDD pin (pin 16) and connect the exposed thermal pad (EP) to a solid ground plane using multiple vias per Microchip UQFN mounting guidelines. The UQFN-16 EP serves both as the chip's primary thermal path and as the electrical ground reference; failing to solder it properly can cause erratic ADC readings and reduced thermal performance. Estimated: with EP soldered to a 1 sq. inch 1 oz copper pour, theta_JA drops to roughly 40 C/W for typical 4x4 mm UQFN-16 parts.
Use Peripheral Pin Select (PPS) early in the schematic phase to lock pin assignments before PCB layout, since reassigning peripherals later can force a board re-spin. PPS allows EUSART, SPI, I2C, PWM, CLC, and CWG signals to be mapped to a wide range of physical pins, but the pin choice still affects analog pin availability for the ADC and DAC. Allocate your analog pins first (RA0/RA1/RA2) and then route digital peripherals around them.
Do not assume PIC16F15323 has EEPROM - the datasheet indicates EEPROM/Data EEPROM may vary by family member and is listed as [DATA_NEEDED] for this specific -I/JQ variant. Use the Flash self-read/write feature for non-volatile parameter storage if EEPROM is unavailable, or migrate to a sibling part that includes Data EEPROM. Also note that -I grade parts are rated only to +85 C; use -E (extended) for +125 C automotive-grade operation.
Estimated: enabling all peripherals at 32 MHz with VDD = 3.3 V draws roughly 4-6 mA, while IDLE mode with CPU stopped drops current to roughly 1-2 mA. Sleep mode with PMD-disabled peripherals can reach low-microampere currents, and full XLP sleep with no active peripherals drops into the nanoampere range per the Microchip PIC16(L)F15313/23 datasheet. Use Peripheral Module Disable (PMD) aggressively in battery-powered designs.
Compliance Information
