MCP25025 Overview
The MCP2502X/5X devices operate as I/O expanders for a Controller Area Network (CAN) system, supporting CAN v2.0B active, with bus rates up to 1 Mb/s. The MCP2502X/5X allows a simple CAN node to be implemented without the need for a microcontroller. The devices are identical, with the following exceptions: Device One Wire A/D Digital CANbus MCP25020 No No MCP25025 No Yes MCP25050 Yes No MCP25055 Yes Yes The MCP2502X/5X devices feature a number of peripherals, including digital I/Os, four-channel 10-bit A/D (MCP2505X), and PWM outputs with automatic message transmission on change-of-input state. This includes an analog input exceeding a preset threshold. One mask and two acceptance filters are provided to give maximum flexibility during system design with respect to identifiers that the device will respond to. The device can also be configured to automatically transmit a unique message...
