Microchip PIC16F1787-I/PT: A Comprehensive Technical Overview
The Microchip PIC16F1787-I/PT stands as a prominent member of the versatile PIC16F family, engineered to deliver a powerful blend of advanced analog integration, robust core performance, and efficient power management. This 8-bit microcontroller is packaged in a 44-pin TQFP (Thin Quad Flat Pack), making it suitable for a wide array of embedded control applications in consumer, industrial, and automotive systems.
At the heart of this MCU lies a high-performance 8-bit RISC CPU core operating at up to 32 MHz, capable of executing most instructions in a single cycle. This ensures deterministic and efficient processing for real-time control tasks. A significant highlight of the PIC16F1787 is its exceptional analog peripheral set. It features a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC2) technology, which allows the ADC to perform signal processing functions autonomously without CPU intervention, dramatically reducing power consumption and freeing up core resources. Complementing this are two 8-bit Digital-to-Analog Converters (DACs) and two operational amplifiers (Op Amps), providing designers with a complete signal chain solution on a single chip.
For control applications, the device is equipped with a rich suite of digital peripherals. This includes Complementary Waveform Generator (CWG), Capture/Compare/PWM (CCP)
modules, and a 16-bit Pulse-Width Modulator (PWM). These are essential for precise motor control, power conversion, and lighting systems. Communication flexibility is provided by multiple serial interface modules, including EUSART (for LIN support), I2C, and SPI, ensuring easy connectivity with a vast ecosystem of sensors, actuators, and communication networks.
The microcontroller incorporates 256 bytes of EEPROM and 14 KB of Flash program memory, offering ample space for complex application code and non-volatile data storage. Its mCore™ peripheral set is designed for capacitive sensing applications, enabling the implementation of touch interfaces without external components.
Operating over an extensive voltage range (2.3V to 5.5V) and a temperature range of -40°C to +85°C, the PIC16F1787-I/PT is built for reliability in harsh environments. Its low-power management modes, such as Idle and Sleep, further enhance its suitability for battery-operated portable devices.
