MCP25020T-I/SL

I/o Expanders Overview

The MCP25020T-I/SL is a CAN I/O expander implementing CAN V2.0B with programmable bit rates up to 1 Mb/s. It features eight general-purpose I/O lines and three auto-transmit buffers. The device operates from 2.7V to 5.5V, drawing 10 mA typical active current and 30 µA in standby. It includes two message reception buffers, one programmable mask, and two acceptance filters. Configuration is stored in non-volatile memory for automatic loading on power-up. The component supports industrial temperature ranges (-40°C to +85°C) and is housed in a 14-pin SOIC package.

I/o Expanders Feature Summary

• Implements CAN V2.0B protocol with hardware-managed message scheduling and error states.
• Provides eight individually selectable digital I/O lines with transmit-on-change-of-state capability.
• Includes non-volatile memory for user configuration that automatically loads upon power-up.
• Supports low-power operation with dedicated sleep mode and automatic wake-up on bus traffic.

I/o Expanders Applications

• CAN nodes requiring simple implementation without a microcontroller
• Digital input monitoring with automatic message transmission on state changes
• System configuration via CAN bus messages

I/o Expanders Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this part number. Confirm the 'I' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the datasheet revision matches the required specifications for your design. Check for any obsolescence notices or recommended replacement parts before finalizing procurement plans.

I/o Expanders Selection Notes

Select this component for applications needing direct CAN interface integration with digital I/O expansion. It eliminates the need for a separate microcontroller in basic node designs. Consider the available buffer sizes and filter configurations for message handling requirements. Verify voltage compatibility within the 2.7V to 5.5V operating range.

I/o Expanders Part Context

The MCP25020T-I/SL belongs to the MCP2502X/5X family of CAN I/O expanders manufactured by Microchip Technology. This series allows for standalone CAN node implementation. The 'T' suffix denotes tape and reel packaging suitable for automated assembly processes. The 'I' suffix specifies the industrial temperature grade.

I/o Expanders Replacement Considerations

Microchip recommends using MCP2515 or MCP25625 as replacements for new designs. These alternatives offer updated features and support while maintaining CAN compatibility. Evaluate pinout and software migration efforts when transitioning from the MCP2502X series.
