Microchip (MCP25050-I/P) I/O Expander, 8bit, 4 MHz

Product Overview
The MCP25050-I/P is an 8-bit I/O Expander operates for a controller area network (CAN) system, supporting CAN V2.0B active, with bus rates up to 1Mb/s. It allows a simple CAN node to be implemented without the need for a microcontroller. It features a number of peripherals, including digital I/Os, four-channel 10-bit A/D and PWM outputs with automatic message transmission on change-of-input state. This includes an analogue 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 unique message whenever any of several error conditions occur. The device is pre-programmed in non-volatile memory so that the part defaults to a specific configuration at power-up.

Implements CAN V2.0B
Non-volatile memory for user configuration - User configuration automatically loaded on power-up
Eight general-purpose I/O lines individually selectable as inputs or outputs
Individually selectable transmit-on-pinchange for each input

Two 10-bit PWM outputs with independently programmable frequencies
Device configuration can be modified via CAN bus messages
In-Circuit Serial Programming™ (ICSP™) of default configuration memory
Low-power CMOS technology

Applications
Industrial, Communications & Networking
