Migrating from the MCP2140 to the
MCP2140A
This section shows you in the major differences
between the MCP2140 and the MCP2140A. Your appli-
cation may have other sensitivities and a complete
system validation should be done.
Table 2-7 shows the differences and enhancements of
the MCP2140A in comparison to the MCP2140.
TABLE 2-7:
DIFFERENCE BETWEEN
MCP2140 AND MCP2140A
2.15
The PIC IrDA Standard Stack
Library and the MCP2140A
The MCP2140A is compatible with the PIC IrDA Stan-
dard Stack Library routines for 16-bit PIC microcon-
trollers. The application must use the Client Library
routines for the IrCOMM 9-wire cooked protocol (for pri-
mary device operation).

Note 1: The external wave shaping circuit is not
required. For applications replacing the
MCP2140, components of the circuit can
be replaced to effectively remove the
waveshaping circuit. See Section 2.13
2: The MCP2140A will drive the CTS signal
active after the UART receive buffer has
59 bytes. The Receive buffer supports the
reception of a 60th byte for systems that
have 0 delay between UART data bytes.
3: Includes 4 bytes overhead for 9-wire
“cooked” protocol. This means that there
are a maximum of 60 data bytes per
frame.
