PIC16F15323T-I/ST Overview
What is a PIC16 8-bit microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, non-volatile Flash program memory, data RAM, and a rich set of peripherals on one die. PIC16 MCUs use a RISC-style modified Harvard architecture and sit inside the broader category of microcontrollers -> embedded controllers -> semiconductor ICs. The PIC16F153xx family adds Core Independent Peripherals (CIPs) and eXtreme Low Power (XLP) features, enabling complex timing, signal generation, and communication tasks without CPU involvement.
The PIC16F15323T-I/ST integrates four 10-bit PWMs, a 5-bit DAC, comparators with selectable references, a 10-bit ADC with computation, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and an EUSART plus SPI/I2C communications. Peripheral Pin Select (PPS) allows flexible remapping of digital peripherals to any I/O pin, simplifying PCB routing on the 14-pin footprint.
Architecturally, the device pairs the enhanced mid-range core with Intelligent Analog and CIP blocks to offload real-time tasks from the CPU, achieving deterministic response in motor control, lighting, and sensor-interface applications. The XLP feature set provides IDLE and DOZE low-power modes, plus Peripheral Module Disable (PMD) to shut down unused peripherals and minimize quiescent current.
Typical applications include low-power IoT sensor nodes, consumer appliances with capacitive touch, LED lighting controllers, battery-powered handheld instruments, and small motor/valve drivers. The 14-TSSOP footprint fits compact boards where the PIC10/PIC12 8-pin parts cannot offer enough peripherals.
When designing with this MCU, leverage Peripheral Pin Select to route peripherals to convenient pins, and use CLC + CWG combinations for hardware-driven timing so the CPU can sleep in XLP modes. Always configure unused pins as outputs and ensure ICD/ICSP connections follow Microchip guidelines for in-circuit debugging.

Typical Applications
PIC16F15323T-I/ST is suitable for 6 applications: Battery-Powered IoT Sensor Node, Consumer Appliance with Capacitive Touch UI, LED Lighting Controller with Dimming, Small DC Motor or Valve Driver, Portable Handheld Measurement Instrument, Industrial Sensor Transmitter (4-20 mA Loop).
Battery-Powered IoT Sensor Node
The PIC16F15323T-I/ST is well suited for battery-powered IoT sensor nodes that must run for years on a coin cell. Its XLP low-power architecture offers IDLE and DOZE modes plus Peripheral Module Disable (PMD) so unused peripherals draw zero current, while the 4x CLC blocks let you build event-driven state machines in hardware so the CPU can sleep between samples. With 3.5 KB Flash and 256 B RAM it has ample room for sensor-fusion or LoRa-WAN-style MAC logic, and the EUSART/SPI/I2C interfaces connect directly to radios and sensors. Compared with an always-on Cortex-M0+ design, the F15323 typically cuts average current by 3-5x, extending battery life in remote deployments where swapping is impractical.

Consumer Appliance with Capacitive Touch UI
In kitchen appliances, white goods, and smart-home devices, the PIC16F15323T-I/ST provides a compact touch-and-display controller. The mTouch peripheral combined with the 10-bit ADC with computation handles 4-8 touch pads without external ICs, while the 4x 10-bit PWMs drive LED indicators and small buzzers. The CLC blocks debounce and combine signals in hardware, freeing the CPU to manage the user interface logic. With 14 TSSOP pins and PPS remapping, you can route the SPI display, I2C sensor bus, and PWM outputs efficiently on a 2-layer board, keeping BOM cost low while delivering a responsive user experience.
Recommended
LED Lighting Controller with Dimming
The PIC16F15323T-I/ST is an excellent fit for dimmable LED drivers in architectural and decorative lighting. Its CWG generates complementary PWM outputs with programmable dead-band control, ideal for half-bridge LED driver topologies, while the 4x 10-bit PWMs handle RGB or warm-white color mixing. The 5-bit DAC and analog comparators support 0-10V or DALI-style analog dimming interfaces. With XLP low-power modes the controller draws under 1 uA in standby, making it suitable for always-on wall-switch and emergency-lighting designs that demand long standby battery life.
Recommended
Small DC Motor or Valve Driver
In small DC motor, solenoid, or valve drivers, the PIC16F15323T-I/ST integrates the timing, sensing, and control loops needed for closed-loop operation. The CWG plus 10-bit PWMs drive H-bridge FETs with hardware dead-time insertion, and the on-chip comparators with selectable references provide fast over-current detection. The ADC with computation performs hardware-averaged current sensing, offloading the CPU for fast fault response. With 32MHz CPU and Core Independent Peripherals, the F15323 closes current loops within a few microseconds, a task that typically requires a more expensive 32-bit MCU when done in software.
Recommended
Portable Handheld Measurement Instrument
Handheld measurement tools such as digital thermometers, light meters, and environmental sensors benefit from the PIC16F15323T-I/ST combination of low power, integrated analog, and small footprint. The 10-bit ADC with computation automates oversampling and averaging for accurate sensor readings, while the on-chip DAC calibrates analog front-end offsets. The EUSART or SPI interfaces stream data to a Bluetooth Low Energy module for smartphone display. XLP modes extend battery life to thousands of measurements per coin cell, critical for field-portable instruments used by technicians and inspectors.
Recommended
Industrial Sensor Transmitter (4-20 mA Loop)
The PIC16F15323T-I/ST can serve as the brain of a 2-wire 4-20 mA loop-powered sensor transmitter used in industrial process control. The 10-bit ADC reads the sensor, the on-chip DAC and PWM combine to drive a current loop with better than 0.1 percent linearity, and the integrated comparator provides loop-fault detection. Its -40C to +85C industrial temperature range suits process plants and remote field installations. The 14-TSSOP footprint and minimal external components enable a transmitter that fits inside standard DIN-form sensor heads, reducing both BOM cost and PCB area.

Key Differentiators
- Integrated Core Independent Peripherals (CLC, CWG) on a 14-pin TSSOP (vs PIC16F15225T-I/ST)

- Extended temperature option in same footprint (vs PIC16F15323T-E/ST)
Design Notes
Use a 0.1 uF decoupling capacitor as close as possible to the VDD pin and a 1 uF bulk capacitor at the board's power entry. For battery designs, the VDD rail can drop to 2.3V on the 'LF' variant; confirm your brown-out reset (BOR) setting matches the minimum operating voltage of your chosen variant. The XLP IDLE current is typically below 1 uA, but software peripherals left running can push this to hundreds of microamps - use the PMD registers to disable every peripheral before sleep.
Keep the ICSP programming lines (ICSPCLK/ICSPDAT) accessible on the PCB. Microchip's ICSP requires the ICSPDAT line to be pulled up to VDD through a resistor (typically 10-50 kohm) to enter programming mode reliably. Place a 4.7 kohm resistor on MCLR to VDD unless you have a dedicated reset supervisor. The TSSOP-14 thermal pad is not present - the part is small enough to operate without copper-area heatsinking for typical embedded loads.
Configure unused pins as outputs low (not inputs) to prevent floating-pin current draw. The PIC16F15323 has Peripheral Pin Select (PPS) - remember that PPS must be UNLOCKED via PPSLOCK before any remapping writes, otherwise the writes silently fail. Watch the ADC acquisition time when using high-impedance sensors; the ADC with computation feature simplifies oversampling but you must still allow adequate holding time before triggering a conversion.
When routing SPI at speeds above 4 MHz, keep traces short and add a series resistor (22-33 ohm) at the MCU end to dampen reflections. The EUSART and SPI pins are 5V tolerant on the input side when VDD is 5V, but not when VDD is 3.3V; do not apply 5V signals to a 3.3V-powered part. Use the configurable logic cells (CLC) to debounce mechanical switch inputs in hardware, freeing the CPU and improving noise immunity.
