MICROCHIP MCP25055-I/P

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.

• 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
• 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
• 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)
• Available temperature ranges: Industrial (I): -40°C to +85°C; Extended (E): -40°C to +125°C
