PIC16F15323-E/ST - 8-Bit 32MHz MCU, 3.5KB Flash, XLP | Microchip
MPN： PIC16F15323-E/ST ✓ 啟用中PIC16F15323-E/ST 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and programmable I/O peripherals. The PIC16 architecture belongs to the broader 8-bit microcontroller category, which sits within the embedded computing -> microcontroller -> MCU IC -> semiconductor taxonomy. The 14-pin TSSOP variant is part of Microchip's general-purpose low-pin-count PIC16 family, intended for compact, low-power designs.
Key differentiating features include 4x 10-bit PWMs with complementary waveform generation, 2x Configurable Logic Cells (CLC), a 5-bit DAC, a comparator, a 10-bit ADC with computation, plus EUSART, SPI, and I2C communication interfaces. Peripheral Pin Select (PPS) allows flexible signal routing, while Peripheral Module Disable (PMD) along with IDLE and DOZE modes enables aggressive power savings under battery operation. XLP technology supports nanoWatt sleep currents suitable for energy-harvesting or coin-cell applications.
Typical applications span consumer electronics, IoT sensor nodes, battery-powered handheld devices, low-cost motor control (small DC fans, PWM-driven LED strings), and home appliance user-interface boards. The combination of CLCs, PWM, and ADC makes it well suited to mixed-signal front ends without external glue logic.
When designing with the PIC16F15323-E/ST, route the ICSP/PGD/PGC programming signals to dedicated pins and provide adequate decoupling (100 nF close to VDD plus a bulk cap). Verify the chosen supply voltage (2.3V-5.5V) against the maximum clock frequency required, because the 32 MHz figure requires VDD >= 2.7V per the datasheet.

典型應用
PIC16F15323-E/ST 適用於 6 應用s: IoT Sensor Node Controller, Battery-Powered Handheld Device, PWM LED Driver Control, Home Appliance User Interface, Automotive Accessory Controller, Industrial Sensor Transmitter.
IoT Sensor Node Controller
Battery-powered IoT sensor nodes benefit from the PIC16F15323-E/ST's XLP nanoWatt sleep modes, which draw nanoamp-level currents during sleep cycles. The 10-bit ADC with computation handles sensor digitization directly, while EUSART or I2C interfaces connect to wireless modules like LoRa or BLE transceivers. The 3.5 KB Flash accommodates lightweight sensor-fusion firmware, and the 14-pin TSSOP package fits compact PCB designs. With 2.3V-5.5V supply range, the MCU operates directly from a 3V coin cell or 2xAA battery pack.

Battery-Powered Handheld Device
Portable consumer electronics like remote controls, fitness trackers, and electronic toys leverage the PIC16F15323-E/ST's combination of low power consumption and integrated peripherals. The 4x 10-bit PWM channels drive LED indicators, buzzers, or small vibration motors without external driver ICs. IDLE and DOZE power modes extend battery life by gating unused peripherals via Peripheral Module Disable (PMD). The 32 MHz CPU speed handles user-interface debouncing, button scanning, and display refresh in real time.

PWM LED Driver Control
The PIC16F15323-E/ST's 4x 10-bit PWM channels and Complementary Waveform Generator (CWG) make it suitable for driving RGB LED strips, dimmable lighting controllers, and small motor speed controls. Each PWM channel provides independent duty-cycle control at up to 32 kHz switching frequency, eliminating flicker in lighting applications. The Peripheral Pin Select (PPS) feature allows PWM outputs to be routed to any available I/O pin, simplifying PCB layout. The 5-bit DAC provides analog reference voltages for LED current control loops.

Home Appliance User Interface
White goods, HVAC controls, and small kitchen appliances use the PIC16F15323-E/ST for keypad scanning, rotary encoder input, and LCD or seven-segment display driving. The Configurable Logic Cells (CLC) implement custom glue logic for button matrix scanning without external AND/OR gates. EUSART connectivity enables communication with main control boards or WiFi/BLE modules for smart-home integration. The -40C to +125C extended temperature range (E suffix) ensures reliable operation in kitchen and laundry environments.

Automotive Accessory Controller
Automotive aftermarket accessories like LED light controllers, seat heaters, and auxiliary lighting benefit from the PIC16F15323-E/ST's extended temperature range and robust peripheral set. The EUSART interface connects to CAN bus transceivers for vehicle network communication. The 10-bit ADC reads sensor inputs (temperature, voltage, current), while PWM channels drive MOSFET switches for heating elements or LED dimming. Note that this part is not AEC-Q100 qualified; for full automotive qualification, consider AEC-Q100-rated PIC16F variants.

Industrial Sensor Transmitter
Industrial 4-20mA current-loop transmitters and process-control sensors use the PIC16F15323-E/ST for signal conditioning, linearization, and communication. The 10-bit ADC digitizes sensor inputs, while the 5-bit DAC generates 4-20mA loop currents via external op-amp drivers. The PIC16's deterministic interrupt latency ensures precise timing for HART or Modbus protocol stacks. The extended -40C to +125C temperature range supports outdoor and factory-floor installations.

主要差異化特點
- Extended temperature range for harsh environments (對比PIC16F15323-I/ST)
- Newest CIP peripheral set in PIC16 family (對比PIC16F15223-I/ST)
- Lower flash density for cost-sensitive designs (對比PIC16F1455-I/ST)
設計說明
The PIC16F15323-E/ST supports a 2.3V-5.5V supply range per the Microchip datasheet. At 2.3V supply, the maximum CPU clock is limited to 16 MHz; at 2.7V and above, 32 MHz operation is allowed. Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 1), with a 10 uF bulk capacitor on the supply rail. For battery applications, use the XLP sleep modes and IDLE/DOZE power-saving features to extend battery life.
Route the ICSP programming pins (PGD and PGC) to a 6-pin header or test pads for in-circuit programming and debugging. Keep the ICSP traces short and avoid routing high-frequency signals adjacent to them. The TSSOP-14 footprint is mechanically different from the SOIC-14 footprint - verify your PCB land pattern matches the chosen package variant before fabrication. Use a ground plane under the MCU to reduce EMI and provide thermal dissipation.
A common pitfall is forgetting the MCLR pull-up resistor on pin 4 (RA3/MCLR). The MCLR pin must be pulled high via a 10 kohm resistor for normal operation; if left floating, the MCU will continuously reset. Another pitfall is enabling peripherals without first configuring PPS mappings - peripheral outputs are not automatically routed to physical pins. Always consult the PPS register table in the datasheet before assigning PWM, UART, or SPI signals to I/O pins.
