MCP25050T-E/SL

I/o Expanders Overview

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

I/o Expanders Feature Summary

• Implements CAN V2.0B protocol with programmable bit rate up to 1 Mb/s
• Includes four 10-bit analog input channels with programmable conversion clock and VREF sources
• Features eight general-purpose I/O lines individually selectable as inputs or outputs
• Contains non-volatile memory for user configuration that loads automatically on power-up

I/o Expanders Applications

• Implementing simple CAN nodes without a microcontroller
• System design requiring maximum flexibility with identifiers via acceptance filters
• Applications needing automatic message transmission on error conditions or input state changes

I/o Expanders Procurement Notes

Verify the 'E' suffix indicates Extended temperature range (-40°C to +125°C) and 'T' denotes tape-and-reel packaging. Confirm the component status is Not Recommended for New Designs (NRND). Ensure compatibility with existing designs before procurement, as Microchip recommends using MCP2515 or MCP25625 for new projects.

I/o Expanders Selection Notes

Select this model when CAN V2.0B compliance and integrated analog-to-digital conversion are required. The 'E' variant is necessary for extended industrial temperatures. Verify that the SOIC-14 package meets board space constraints. Consider the NRND status and potential migration paths to MCP2515 or MCP25625 if future production longevity is a priority.

I/o Expanders Part Context

This part belongs to the MCP2502X/5X family of CAN I/O expanders. The MCP25050 variant specifically includes analog input capabilities, distinguishing it from the MCP25020 which lacks A/D converters. The family supports both standard and extended CAN identifiers and offers hardware-based message scheduling and edge detection features.

I/o Expanders Replacement Considerations

Microchip explicitly recommends using MCP2515 or MCP25625 as replacements for new designs. These alternatives offer updated features and support while maintaining functional compatibility with the CAN I/O expander architecture.
