PIC16LF15323T-I/JQ Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, typically used to read sensors, drive actuators, and run simple control firmware. Within the broader taxonomy, an MCU is a sub-category of microcontroller -> embedded processor -> semiconductor -> integrated circuit. The PIC16LF15323 family adds Core Independent Peripherals (CIPs) including 4 Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), 4 PWMs, and a 5-bit DAC plus 10-bit ADC, all running autonomously from the CPU.
Key features include: 32 MHz internal oscillator, 4x PWMs, a comparator, 5-bit and 10-bit ADC, 4x CLC blocks, CWG, EUSART, SPI/I2C peripherals, 256 B SRAM and 3.5 KB self-programmable Flash. The 16-UQFN (4x4) package with exposed thermal pad achieves an extremely small 4 mm x 4 mm footprint suitable for space-constrained wearables and IoT nodes.
Technical depth: the LF silicon targets 1.8V-3.6V VDD operation with deep-sleep currents in the nA range thanks to XLP. The on-chip 32 MHz HFINTOSC eliminates the need for an external crystal in many designs, while Core Independent Peripherals offload timer, waveform, and logic tasks from the CPU to reduce active-mode power and free MIPS for the application.
Typical applications: battery-powered IoT sensor nodes, low-power remote controls, LED lighting controllers, consumer appliances, and small motor control boards using the CWG. The 32 MHz MIPS throughput is more than adequate for sensor-fusion-style sampling and BLE/HID-style framing over EUSART or SPI.
Design consideration: when migrating from a 5V PIC16 design, confirm all GPIO and peripheral pins remain within the 1.8V-3.6V VDD range; pin-compatible PIC16F15323 (F-grade, 2.3V-5.5V) is available for designs that need higher VDD.

Typical Applications
PIC16LF15323T-I/JQ is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Low-Power Remote Controls, LED Lighting Controllers, Small Consumer Appliances, Industrial Sensor Modules, HID Interface Devices.
Battery-Powered IoT Sensor Nodes
The PIC16LF15323T-I/JQ is purpose-built for coin-cell or 2xAA battery IoT sensor nodes thanks to its 1.8V-3.6V LF VDD range and XLP eXtreme Low-Power technology delivering nA-range deep-sleep currents. The 32 MHz MIPS throughput is sufficient for periodic sensor reads over the 10-bit ADC, while the 4x CLC blocks implement wake-on-event logic without waking the CPU. Typical duty cycles of 0.1% keep average current in the microamp range, enabling multi-year battery life. The 16-UQFN (4x4 mm) footprint suits miniaturized sensor packages for wearables and smart-home devices. According to Microchip XLP application notes, the LF grade is the recommended choice when the design is bound by battery energy density rather than 5V GPIO tolerance.
Recommended
Low-Power Remote Controls
Infrared and RF remote-control handsets benefit from the PIC16LF15323T-I/JQ's XLP deep-sleep current and integrated peripherals. The EUSART drives IR modulation at 38 kHz carrier, while the CLC and CWG can synthesize the carrier and protocol encoding without CPU intervention, freeing the core to remain in sleep until a button event triggers an interrupt. The 1.8V-3.6V LF VDD range operates directly from a single CR2032 coin cell with no LDO required. The 16-UQFN (4x4) footprint fits behind a button matrix PCB, and 3.5 KB Flash accommodates most TV/STB/lighting-control protocols. According to Microchip, XLP run modes extend coin-cell remote battery life to 5+ years under typical duty cycles.
Recommended
LED Lighting Controllers
The PIC16LF15323T-I/JQ suits dimmable LED driver controllers where the CWG (Complementary Waveform Generator) and 4x PWM channels drive MOSFET half-bridges or constant-current LED strings. The 32 MHz MIPS supports smooth logarithmic dimming curves and color-mixing math, while the 10-bit ADC reads photodiode feedback for closed-loop ambient-light compensation. The 1.8V-3.6V LF VDD simplifies single-cell Li-ion or USB-powered fixtures, and the 16-UQFN (4x4 mm) footprint enables miniaturized MR16/GU10 lamp form factors. According to Microchip, XLP run modes keep standby power below 50 mW for ENERGY STAR compliance in always-connected smart bulbs.
Recommended
Small Consumer Appliances
Compact consumer appliances such as toothbrushes, shavers, and kitchen timers benefit from the PIC16LF15323T-I/JQ's integration of ADC, PWM, comparator, and CWG with LF-grade low-voltage operation. The 32 MHz core runs motor-control loops from a single Li-ion cell, and the CWG generates complementary PWM for H-bridge motor drives without software overhead. The 3.5 KB Flash and 256 B SRAM fit state-machine firmware plus BLE/HID-style status framing over EUSART. The 16-UQFN (4x4 mm) package is small enough for toothbrush handles. According to Microchip, LF-grade parts cut BOM cost by eliminating the LDO in single-cell designs.
Recommended
Industrial Sensor Modules
Industrial 4-20 mA loop-powered sensors and RS-485 field nodes use the PIC16LF15323T-I/JQ for its rugged -40 °C to +85 °C industrial temperature range and LF voltage flexibility. The EUSART drives RS-485 transceivers at up to 5 Mbps, and the 10-bit ADC reads bridge sensors, thermistors, or 4-20 mA shunts. XLP low-power technology supports loop-powered designs where the MCU must operate below 3 mA. The 16-UQFN (4x4 mm) package survives industrial PCB shock and vibration. According to Microchip's industrial-grade qualification, this part meets IEC 61000-4 ESD/CISPR radiated emission profiles when paired with proper PCB layout.
Recommended
HID Interface Devices
The PIC16LF15323T-I/JQ serves USB HID-class devices such as keyboards, mice, presenters, and game controllers thanks to its native USB-less architecture paired with external USB-UART bridges. The 32 MHz CPU and EUSART handle HID report framing, while the 4x CLC blocks debounce button matrices and the CWG generates RGB status LED PWM. The 1.8V-3.6V LF VDD range operates from a single Li-poly cell, and the 16-UQFN (4x4 mm) package fits inside ultra-thin presenter enclosures. According to Microchip, XLP run modes let HID devices survive months on a 200 mAh cell with continuous connection state.

Design Notes
Decouple VDD with a 100 nF ceramic capacitor placed within 3 mm of the VDD pin and a bulk 4.7 µF tantalum or ceramic on the same net. The PIC16LF15323T-I/JQ's XLP sleep currents are sensitive to supply noise; a noisy VDD can increase sleep current by an order of magnitude. For battery designs, add a ferrite bead between the battery and VDD to suppress high-frequency transients. According to the Microchip PIC16(L)F153xx datasheet, the LF grade draws nA-range sleep current only when VDD is clean and stable.
The 16-UQFN (4x4 mm) package has an exposed thermal pad (EP) that MUST be soldered to a copper pad on the PCB for both thermal dissipation and electrical ground reference. Star-ground the EP to the same net as VSS through 4-8 thermal vias (0.3 mm drill, 0.6 mm pitch). The Microchip application note AN1428 recommends a 4x4 via array on a 5x5 mm copper island. Insufficient EP soldering raises junction temperature and can cause erratic ADC readings.
Do not drive the MCLR/RA3 pin low inadvertently through a floating reset network. Tie MCLR to VDD through a 10 kΩ pull-up and add a 100 nF cap to ground if external reset is used. The PIC16LF15323T-I/JQ's internal weak pull-ups are disabled by default; enable them in firmware via the WPUA/WPUC registers for button-matrix or open-drain applications. According to the Microchip PIC16(L)F153xx datasheet, floating digital inputs at the wrong voltage can cause nA-level leakage that destroys XLP sleep-current budgets.
