MCP25020-E/SL

I/o Expanders Overview

The MCP25020-E/SL is a CAN I/O expander from the MCP2502X/5X family, designed to implement CAN v2.0B active protocols with bus rates up to 1 Mb/s. It operates on a single supply voltage ranging from 2.7V to 5.5V and features eight general-purpose I/O lines individually selectable as inputs or outputs. The device includes three auto-transmit buffers and two message reception buffers, along with one programmable mask and two programmable filters for identifier acceptance. It utilizes non-volatile memory for user configuration that loads automatically on power-up. The component is housed in a 14-pin SOIC package and supports an extended temperature range of -40°C to +125°C.

I/o Expanders Feature Summary

• Implements CAN V2.0B protocol with programmable bit rates up to 1 Mb/s
• Features eight general-purpose I/O lines individually selectable as inputs or outputs
• Includes non-volatile memory for user configuration that loads automatically on power-up
• Provides hardware error management logic with automatic wake-up on bus traffic

I/o Expanders Applications

• CAN system nodes requiring I/O expansion without a microcontroller
• Industrial automation systems utilizing CAN communication
• Automotive embedded control applications

I/o Expanders Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'E' designation indicates the extended temperature range, while 'SL' specifies the SOIC package. Ensure compatibility with existing CAN bus configurations regarding voltage levels and timing requirements before procurement.

I/o Expanders Selection Notes

Select this component when a standalone CAN node with digital I/O capabilities is required without a central processor. Consider the MCP25025 variant if optional 1-wire CAN bus operation is needed. Verify that the eight available GPIOs meet the interface requirements, as analog input channels are not present in this specific model.

I/o Expanders Part Context

The MCP25020-E/SL belongs to the MCP2502X/5X CAN I/O Expander Family manufactured by Microchip Technology. This family allows simple CAN node implementation without a microcontroller. The device is part of a series differentiated by features such as analog-to-digital conversion and 1-wire capability found in other variants like the MCP25050.

I/o Expanders Replacement Considerations

Microchip recommends using the MCP2515 or MCP25625 instead of this device for new designs.
