Migrating Designs from MCP201 to MCP2021-500
The original MCP201 LIN (Local Interconnect Network) transceiver was designed to comply with LIN 1.2 and 1.3 physical layer specifications. The MCP2021-500 is designed to be pin- and functionally-compatible with the earlier MCP201, and to meet the latest LIN 2.0 and 2.1 specifications. For most applications, the MCP2021-500 can be dropped in place of a MCP201 in an existing design without printed circuit board or firmware modifications. This application note outlines some considerations to be made when evaluating the upgrade to MCP2021-500.
