The IrDA Standard specifies the following protocols:
Physical Signaling Layer (PHY)
Link Access Protocol (IrLAP)
Link Management Protocol/Information Access
Service (IrLMP/IAS)
The IrDA data lists optional protocols. They are:
Tiny TP
IrTran-P
IrOBEX
IrLAN
IrCOMM
IrMC
IrDA Lite
Figure B-2 shows the IrDA data protocol stack and
which components are implemented by the MCP2140.

IrDA STANDARD DATA
PROTOCOLS SUPPORTED BY
MCP2140
The MCP2140 supports these required IrDA standard
protocols:
Physical Signaling Layer (PHY)
Link Access Protocol (IrLAP)
Link Management Protocol/Information Access
Service (IrLMP/IAS)
The MCP2140 also supports some of the optional pro-
tocols for IrDA data. The optional protocols that the
MCP2140 implements are:
Tiny TP
IrCOMM
B.1.1
PHYSICAL SIGNAL LAYER (PHY)
The MCP2140 provides the following Physical Signal
Layer specification support:
Bidirectional communication
Data Packets are protected by a CRC
- 16-bit CRC for speeds up to 115.2 kbaud
Data Communication Rate
- 9600 baud minimum data rate (with primary
speed/cost steps of 115.2 kbaud
The following Physical Layer Specification is depen-
dant on the optical transceiver logic used in the
application. The specification states:
Communication Range, which sets the end user
expectation for discovery, recognition and
performance.
- Continuous operation from contact to at least
1 meter (typically 2 meters can be reached)
- A low power specification reduces the objec-
tive for operation from contact to at least
20 cm (low power and low power) or 30 cm
(low power and standard power)
