1 / 66 page  © 2007 Microchip Technology Inc. DS21664D-page 1 MCP2502X/5X Features • Implements CAN V2.0B - Programmable bit rate up to 1 Mb/s - One programmable mask - Two programmable filters - Three auto-transmit buffers - Two message reception buffers - Does not require synchronization or configuration messages • Hardware Features - 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-pin- change for each input - Four 10-bit, analog input channels with programmable conversion clock and VREF sources (MCP2505X devices only) - Message scheduling capability - 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 - Optional 1-wire CAN bus operation • Low-power CMOS technology - Operates from 2.7V to 5.5V - 10 mA active current, typical - 30 µA standby current (CAN Sleep mode) • 14-pin PDIP (300 mil) and SOIC (150 mil) packages • Available temperature ranges: - Industrial (I): -40°C to +85°C - Extended (E): -40°C to +125°C Description 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: 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 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.
