Microchip PIC16F15375-I/PT 8-Bit Microcontroller: Features and Application Design Guide
The Microchip PIC16F15375-I/PT is a versatile 8-bit microcontroller from Microchip’s enhanced mid-range PIC16F family. Built on a robust PIC® architecture, this MCU combines high performance with low power consumption, making it suitable for a wide range of embedded applications. Available in a 44-pin TQFP package, it offers an optimal balance of processing power, peripheral integration, and physical footprint.
Key Features
At the core of the PIC16F15375 is an enhanced 8-bit CPU with a hardware multiplier, enabling efficient arithmetic operations. It operates at a maximum frequency of 32 MHz, delivering up to 8 MIPS of performance. The device includes 28 KB of Flash program memory and 2 KB of RAM, providing ample space for complex firmware.
A standout feature of this microcontroller is its rich set of integrated peripherals:
Analog: It houses a 12-channel 10-bit Analog-to-Digital Converter (ADC) with computation capabilities, two 8-bit Digital-to-Analog Converters (DACs), and two comparators.
Control & Communication: It is equipped with multiple communication interfaces, including EUSART (for UART), SPI, and I2C modules, facilitating seamless connectivity with sensors, displays, and other ICs.
Timing & Control: The MCU features 5 timers/counters (including a 16-bit timer), five Capture/Compare/PWM (CCP) modules, and two Complementary Waveform Generators (CWG) for advanced motor control and power conversion applications.
Core Independent Peripherals (CIPs): These are hardware-based modules like the Configurable Logic Cell (CLC), Windowed Watchdog Timer (WWDT), and Memory Access Partition (MAP), which operate without CPU intervention. This significantly reduces software overhead and power consumption while enhancing system reliability.
Application Design Guide
1. Motor Control Systems: Leverage the Complementary Waveform Generator (CWG) and multiple PWM modules to design efficient brushless DC (BLDC) or stepper motor controllers. The CIPs allow for dead-time control and fault protection entirely in hardware, creating a responsive and safe system.
2. Sensor Interface & Data Logging: The 10-bit ADC with Computation (ADCC) can perform averaging, filtering, and threshold comparisons on analog sensor data (e.g., temperature, pressure) without waking the core CPU. This is ideal for battery-powered data logger applications where low power is critical.
3. Consumer Electronics & Human-Machine Interface (HMI): Use the integrated peripherals to create rich user interfaces. The multiple I/O pins can drive LEDs or scan keypads, while the communication interfaces (I2C/SPI) can connect to LCDs or touch sensor controllers.
4. Power-Sensitive IoT Nodes: The microcontroller’s low-power modes (e.g., Sleep, Idle) and ability for peripherals to operate autonomously make it perfect for intermittent operation devices. A timer or external interrupt can wake the device from sleep, take a sensor reading using the ADC, transmit it via EUSART to a wireless module, and return to sleep—all while minimizing active time.
5. Industrial Control & Automation: The Configurable Logic Cell (CLC) allows designers to create custom combinatorial or sequential logic functions between peripherals and I/O pins in hardware. This can be used to create instant responses to external events, such as triggering a PWM shutdown upon a fault signal, enhancing system safety and speed.
When designing with the PIC16F15375, always utilize Microchip’s MPLAB® X IDE and the MPLAB Code Configurator (MCC). MCC is a powerful tool that generates initialization code and drivers for the complex peripherals, dramatically accelerating development time and reducing potential configuration errors.
ICGOOODFIND: The PIC16F15375-I/PT is a highly integrated and flexible 8-bit microcontroller. Its strength lies in its comprehensive peripheral set, Core Independent Peripherals (CIPs) for autonomous operation, and robust development tool ecosystem. It is an excellent choice for designers seeking to add intelligent control, analog interfacing, and connectivity to their products while optimizing for power and performance.
