Microchip PIC18F57Q84-I/PT 8-Bit Microcontroller Overview and Application Guide
The Microchip PIC18F57Q84-I/PT represents a significant evolution in the PIC18 family of 8-bit microcontrollers, combining robust performance with advanced peripheral integration. This powerful MCU is engineered to address the growing demands of complex embedded applications, from industrial automation and automotive systems to consumer electronics and IoT edge devices.
At its core, the device operates at up to 64 MHz, delivering a substantial 128 KB of Flash program memory and 8 KB of SRAM, providing ample space for sophisticated application code and data handling. A key feature is its Direct Memory Access (DMA) controller, which offloads data transfer tasks from the CPU, significantly enhancing throughput and system efficiency. This is particularly beneficial for data-intensive operations like sensor data logging or communication interfaces.
The peripheral set is exceptionally rich. It includes multiple communication protocols such as I2C, SPI, and EUSART (Enhanced Universal Synchronous Asynchronous Receiver Transmitter), making it easy to interface with a vast array of sensors, displays, and other peripherals. For analog needs, it boasts a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC²) and a 10-bit Digital-to-Analog Converter (DAC), enabling precise measurement and control of analog signals. Furthermore, it integrates Core Independent Peripherals (CIPs) like Configurable Logic Cells (CLCs), which allow for the creation of custom logic functions without CPU intervention, thereby increasing design flexibility and reliability.
The inclusion of hardware security features, such as Memory Protection Unit (MPU) and Code Guard, helps protect intellectual property and secure firmware from unauthorized access. Housed in a 48-pin TQFP package, the PIC18F57Q84-I/PT offers a compact footprint suitable for space-constrained designs while providing a high number of I/O pins for extensive connectivity.
