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 C-2 shows the IrDA data protocol stack and

IrDA STANDARD DATA
PROTOCOLS SUPPORTED BY
MCP2140A
The MCP2140A supports these required IrDA standard
protocols:
Physical Signaling Layer (PHY)
Link Access Protocol (IrLAP)
Link Management Protocol/Information Access
Service (IrLMP/IAS)
The MCP2140A also supports some of the optional
protocols for IrDA data. The optional protocols that the
MCP2140A implements are:
Tiny TP
IrCOMM
C.1.1
PHYSICAL SIGNAL LAYER (PHY)
The MCP2140A 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
dependant 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
objective for operation from contact to at least
20 cm (low power and low power) or 30 cm
(low power and standard power)

Note 1: The MCP2140A implements the 9-wire
“cooked” service class serial replicator.
2: The MCP2140A is fixed at 9600 Baud.
3: An optical transceiver is required.
Note:
MCP2140A supports 9600 Baud only.
