DEVELOPMENT TOOLS

The MCP2155 is

supported by the

MCP2120/

MCP2150 Developer’s Kit (order number DM163008).

This kit allows the user to demonstrate the operation of

the MCP2155 by doing some hardware “cuts” on the

MCP2150 Developer’s board.

Each kit (DM163008) comes with two MCP2120 Devel-

oper’s boards and one MCP2150 Developer’s Board to

demonstrate transmission/reception of infrared data

streams. Figure 3-1 shows a block diagram of the

MCP2150 Developer’s Board and the 4 lines that are to

be “cut”. The use of MCP2155 requires that the Header

interface is used (SP3238E disconnected from sys-

tem).

As can be seen, the user has jumper options for both

the interface to the host controller (UART or Header)

and the transceiver solution (Integrated or discrete

component).

The UART interface allows a direct connection to a PC

(use a terminal emulation program), or a header to

allow easy connection to host prototypes (or one of the

Microchip PICDEM™ boards).

The transceiver logic is jumpered to allow the selection

of either a single chip transceiver solution, or a low cost

discrete solution. This low cost discrete solution allows

a lower system cost to be achieved. With the lower cost

comes some trade-offs of the IrDA standard physical

layer specifications. These trade-offs need to be evalu-

ated to ensure the characteristics of the component

solution meet the requirements of the system.

This kit comes with two identical MCP2120 Devel-

oper’s Boards and a single MCP2150 Developer’s

board. This allows a complete system (Transmitter and

Receiver) to be implemented with either system

requirement (simple encoder/decoder or IrDA standard

protocol stack plus encoder/decoder).

(Note)

Note:

The MCP2150 which comes standard in the MCP2150 Developer’s Kit may be replaced with the

MCP2155. Some signals from the UART drive chip (SP3238E) need to be cut in order to ensure that no

I/O conflicts will occur.
