MPN: PIC16F15375-E/PT ✓ Hoạt độngPIC16F15375-E/PT Tóm tắt
An 8-bit microcontroller (MCU) is a compact, low-cost processor built around an 8-bit data path, widely used in embedded systems where deterministic real-time response, simple peripheral integration, and low power are more important than raw computational throughput. Within the broader semiconductor hierarchy, an MCU sits under microcontrollers -> embedded processors -> logic ICs -> integrated circuits. The PIC16F15375 belongs to the PIC16 mid-range family and combines a RISC-like Harvard architecture with extensive on-chip analog and digital peripherals, enabling many designs to be realized without external ADC, DAC, comparator, or PWM ICs.
Key features include 35 channels of 10-bit ADC, 2 DAC channels, 2 comparators, 4 PWM outputs, a Complementary Waveform Generator (CWG), 2 EUSART modules, 2 SPI and 2 I2C interfaces, plus eXtreme Low-Power modes with nanoWatt XLP technology. The 44-TQFP (PT) package gives 36+ general-purpose I/O pins, making it suitable for I/O-rich human-interface and sensor-hub designs. The integrated peripherals support signal conditioning, motor control loops, and communication bridging without external glue logic.
The architecture uses a 14-bit instruction word with a 32MHz internal oscillator, providing single-cycle instruction execution and predictable interrupt latency. Intelligent Analog peripherals such as the 10-bit ADC with hardware Capacitive Voltage Divider (CVD), zero-cross detect, and slope compensation are tightly coupled with CIPs like CWG and Numerically Controlled Oscillator (NCO), enabling sophisticated control loops in firmware-light environments.
Typical applications include IoT sensor nodes, low-power wireless HMI panels, BLDC fan and pump controllers, LED lighting controllers, battery chargers, and consumer appliance front-panel controllers. The combination of 14KB Flash and 1KB RAM supports a real-time OS or state-machine architecture with room for bootloaders.
When designing with this part, ensure the VDDCORE pin has a 1µF decoupling capacitor within 2mm and that MCLR is pulled high through a 10kΩ resistor; failure to do this can cause programming or brown-out-reset issues. For low-power designs, leverage the DOZE and SLEEP modes to reduce quiescent current below 1µA.

Ứng dụng tiêu biểu
PIC16F15375-E/PT phù hợp cho 7 Áp dụngs: IoT Sensor Hub, BLDC Fan / Pump Controller, LED Lighting Controller, Battery Charger Front-End, Consumer Appliance HMI Panel, Industrial Sensor Transmitter, Automotive Body Module.
IoT Sensor Hub
The PIC16F15375-E/PT is well-matched to IoT sensor-hub nodes thanks to its 35-channel 10-bit ADC for multi-sensor polling, 2 I2C/SPI ports for digital sensors, and eXtreme Low-Power XLP modes that drop quiescent current below 1uA in Sleep. At 32MHz the core services 4 PWM channels for local actuator control and runs a state-machine RTOS in 14KB Flash with 1KB RAM. The 44-TQFP package exposes 36 I/O for button, LED, and display matrix expansion, while the integrated CWG generates carrier waveforms for IR or sub-GHz transceivers.
Được đề xuất
BLDC Fan / Pump Controller
The PIC16F15375-E/PT drives small BLDC and brushed-DC fan/pump controllers with its 4 10-bit PWM channels and Complementary Waveform Generator (CWG), which produces dead-band-corrected complementary outputs for synchronous half-bridge or full-bridge drive. The 2 on-chip comparators perform zero-cross back-EMF detection, while the 10-bit ADC samples current via shunt amplifier. At 32MHz the core closes a 20kHz commutation loop with margin for housekeeping, and XLP modes cut idle current for battery-powered appliance designs.
Được đề xuất
LED Lighting Controller
The PIC16F15375-E/PT fits architectural and commercial LED lighting controllers because 4 PWM channels plus CWG can drive RGBW or dual-channel constant-current stages with hardware timing. The 35-channel ADC reads ambient light sensors, thermistors for thermal fold-back, and potentiometer dimmers. The 2 DAC channels provide 0-10V analog dimming outputs, while EUSART and I2C connect to DALI-2 or DMX bridge chips. Operating from 2.3-5.5V the part is compatible with both 3.3V logic LED drivers and 5V analog dimming rails.

Battery Charger Front-End
The PIC16F15375-E/PT serves as the front-end controller in Li-ion / NiMH battery chargers, using the 10-bit ADC to monitor voltage, current, and temperature with 35 channels for cell-balancing telemetry. The 2 comparators implement hardware over-current and over-voltage protection independent of firmware, and the CWG produces synchronous-rectifier timing. The 14KB Flash supports CC-CV profiles plus a bootloader for field firmware updates, while 1KB RAM buffers coulomb-counting state. Extended -40C to +125C operation suits under-hood automotive packs.
Được đề xuất
Consumer Appliance HMI Panel
The PIC16F15375-E/PT powers appliance HMI panels (washing machines, ovens, coffee machines) thanks to its 36 I/O for capacitive-touch buttons via the hardware CVD peripheral, LED matrix driving via PWM, and segment-LCD bias via timer peripherals. The 2 EUSART bridges to Wi-Fi/BLE modules for smart-appliance connectivity, while the 2 I2C ports read digital temperature and humidity sensors. Extended temperature operation and 44-TQFP surface-mount package suit sealed kitchen enclosures where convection cooling is limited.
Được đề xuất
Industrial Sensor Transmitter
The PIC16F15375-E/PT builds 4-20mA / 0-10V industrial sensor transmitters with its 10-bit ADC digitizing bridge sensors, RTDs, or thermocouples via the on-chip 2 DAC channels and 2 comparators for fault detection. The 2 EUSART and 2 SPI ports drive RS-485 transceivers or wireless modules, and the CWG generates excitation waveforms for LVDT sensors. Extended -40C to +125C operation handles factory-floor thermal stress, while 14KB Flash supports Modbus, HART-lite, or IO-Link protocols alongside calibration routines.
Được đề xuất
Automotive Body Module
The PIC16F15375-E/PT is well suited for low-speed automotive body modules (window lift, seat control, mirror adjust) thanks to its extended -40C to +125C grade, 4 PWMs for motor drive, and 35 ADC channels for current and position sensing. The 2 LIN-capable EUSARTs interface to vehicle bus networks, while the 44-TQFP package survives automotive vibration profiles. Although not AEC-Q100 qualified itself, the part is used in non-safety body controllers where industrial temperature grade suffices.

Ghi chú thiết kế
Place a 1uF low-ESR ceramic decoupling capacitor within 2mm of the VDDCORE pin (pin 41) and a 100nF cap on VDD (pin 9) plus AVSS/AVDD (pins 39-40) for the analog domain. The internal core regulator on PIC16F15375-E/PT powers the digital logic from VDDCORE; insufficient decoupling causes brown-out resets under PWM switching loads. Tie AVDD to VDD and AVSS to VSS if analog accuracy is not critical to free up board space, but route separate traces if ADC noise performance matters.
Route the ICSPDAT/ICSPCLK pins (typically RB7/RB6) away from high-current PWM traces and analog inputs to avoid programming glitches in production. The MCLR/VPP pin (pin 44) needs a 10kΩ pull-up to VDD and a 100nF cap to ground for in-circuit programming; do not place a diode on MCLR in production designs since it blocks ICSP. Keep the 32.768kHz crystal traces (RC0/RC1, pins 19-20) short and guarded with a ground pour for low-power RTC accuracy.
Do not leave unused comparator or DAC outputs floating - tie them to VSS or VDD through 10kΩ to prevent parasitic current draw in Sleep mode. When migrating from PIC16F1527 to PIC16F15375, note that PPS (Peripheral Pin Select) mapping changed and CWG pin assignments differ; re-validate configuration bits. For automotive under-hood use, choose PIC16F15375-E/PT (extended grade) over PIC16F15375-I/PT (industrial grade); the I variant derates to +85C maximum.
At 32MHz and 5.5V supply the PIC16F15375-E/PT draws roughly 5.5mA active current per the family datasheet DC characteristics, dissipating about 30mW. In the 44-TQFP package (theta-JA around 50 C/W on a 4-layer JEDEC board) this gives a junction temperature rise of only 1.5C - thermal management is rarely needed. However, when the part operates in sealed enclosures at +85C ambient with adjacent switching regulators, derate clock speed or enable Doze mode to keep junction below +125C.
The 10-bit ADC on PIC16F15375-E/PT achieves best SNR (~61 dB) when acquisition time is set above the minimum 1us and the source impedance is below 10kΩ; use an external input buffer for higher-impedance sensors. Enable the ADC's hardware Capacitive Voltage Divider (CVD) for robust capacitive-touch sensing, which rejects moisture and temperature drift. For PWM-driven LED loads, gate the ADC sampling in software to align with PWM off-time to avoid switching-noise coupling.
