MCP25050T-I/SL

I/o Expanders Overview

The MCP25050T-I/SL is a CAN I/O expander implementing the CAN V2.0B protocol with programmable bit rates up to 1 Mb/s. It features eight general-purpose I/O lines and four 10-bit analog input channels with programmable conversion clocks and voltage reference sources. The device includes three auto-transmit buffers, two message reception buffers, one programmable mask, and two programmable filters. Operating from 2.7V to 5.5V, it draws 10 mA typical active current and 30 µA in standby mode. Configuration is stored in non-volatile memory for automatic loading on power-up.

I/o Expanders Feature Summary

• Implements CAN V2.0B protocol with hardware error management logic and bus-off recovery capabilities.
• Integrates four-channel 10-bit analog-to-digital converter with programmable thresholds and conversion clocks.
• Provides eight individually selectable digital I/O lines with transmit-on-change-of-state functionality.
• Supports automatic message transmission triggered by digital edge detection or analog threshold exceedance.

I/o Expanders Applications

• Standalone CAN nodes requiring peripheral expansion without microcontrollers
• Industrial sensor interfaces utilizing analog input channels
• Automotive systems requiring robust error handling and low-power sleep modes

I/o Expanders Procurement Notes

Verify the specific suffix 'I/SL' against official Microchip documentation to confirm industrial temperature range and SOIC package specifications. Ensure compatibility with existing system voltage levels between 2.7V and 5.5V. Confirm that the component meets all required CAN V2.0B timing parameters before integration into the design.

I/o Expanders Selection Notes

Select this component when a standalone CAN node with integrated analog inputs and digital I/O is required. It eliminates the need for an external microcontroller in simple monitoring applications. Consider the MCP2515 or MCP25625 for new designs as per manufacturer recommendations due to updated feature sets.

I/o Expanders Part Context

This part belongs to the MCP2502X/5X family of CAN I/O expanders manufactured by Microchip Technology. The 'MCP25050' designation indicates the inclusion of analog input channels but excludes optional 1-wire operation. The 'I' suffix denotes the industrial temperature range, while 'SL' specifies the 14-pin SOIC package type.

I/o Expanders Replacement Considerations

Microchip recommends using the MCP2515 or MCP25625 for new designs instead of this component. These alternatives offer updated features and support while maintaining functional compatibility with CAN V2.0B protocols.
