选择MCP21XX器件的IrDA®应用

With a growing number of device options within the
MCP21XX family, this Technical Brief serves as a
guide in helping to select the device for your
application.
All of the MCP21XX devices interface to the Host
Controller with a UART. The MCP2120 and MCP2122
devices use only the TX and RX signals. The
MCP215X and MCP2140 devices also use the TX and
RX signals, as well as up to 6 other non-data signals.
For additional information on this Host UART interface
for the MCP215X (also valid for the MCP2140), please
refer to Application Note 858, “Interfacing The
MCP215X to a Host Controller“, DS00858.
