Housed in a 44-pin TQFP package, this device is engineered for a wide array of embedded control applications, leveraging its robust architecture and advanced features to simplify design and enhance functionality.

At its core, the PIC16F1517 is built on Microchip's enhanced mid-range core with a 16-level deep hardware stack and 49 instructions. It operates at a maximum frequency of 32 MHz, providing a solid balance of processing power and energy efficiency. A standout feature of this microcontroller is its extensive memory configuration, comprising 28 KB of programmable Flash memory and 2 KB of RAM, offering ample space for complex application code and data handling.

One of the most significant strengths of the PIC16F1517 is its rich set of integrated peripherals, which reduces the need for external components and lowers overall system cost. Key peripherals include:

Complementary Waveform Generator (CWG): This module is critical for advanced motor control and power conversion applications, allowing the generation of complementary PWM signals with dead-band control to drive half-bridge and full-bridge circuits safely.

Hardware Capacitive Voltage Divider (CVD): This technology enhances touch sensing capabilities,

enabling the implementation of robust and noise-resistant capacitive touch interfaces without external components. It supports proximity and touch sensing for modern user interfaces.

Enhanced Communication Interfaces: The device is equipped with multiple serial communication modules, including EUSART (for UART), MSSP (for I²C and SPI), and a Dedicated LIN/J2602 Interface, making it ideal for networked automotive and industrial systems.

Analog Integration: It features a 10-bit Analog-to-Digital Converter (ADC) with up to 32 channels, two comparators, and a fixed voltage reference (FVR), providing extensive analog signal measurement and control capabilities.

Core Independent Peripherals (CIPs): Peripherals like Timers, CWG, and CVD can operate without constant CPU intervention, enabling low-power operation and deterministic response to events.

The combination of these features makes the PIC16F1517-I/PT exceptionally suited for a diverse range of applications. Its advanced motor control peripherals, such as the CWG, make it a prime choice for brushless DC (BLDC) motor control in appliances, drones, and industrial fans. The integrated CVD hardware is perfect for building touch-sensitive control panels in consumer white goods, automotive dashboards, and industrial HMIs. Furthermore, its communication interfaces and analog capabilities allow it to serve as a smart sensor hub, a node in building automation systems, or a controller in low-power battery-operated devices.
