Overview
The Microchip PIC18F8585 microcontroller includes a CAN interface. It is a high-performance 8-bit microcontroller suitable for industrial control and embedded applications. The device supports various programmer interfaces, standard C programming, and offers a range of peripherals, communication interfaces, and debugging features.
The MCU uses a Harvard architecture, with a maximum operating frequency of 40 MHz, 96 KB of flash memory, and 4 KB of RAM. It also provides multiple analog and digital peripheral interfaces, including an analog-to-digital converter, comparators, PWM generators, timers, UART, SPI, and I2C communication interfaces.
The PIC18F8585 also includes advanced features such as 8-bit and 16-bit fixed-point adders, an I2S port, encoder interface, and multiple timer modes for efficient data handling. Safety and reliability features include configurable pull-ups/pull-downs, fail-safe reset, calendar/timer functions, and an independent watchdog.
