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.

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
