Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is intended through suggestion only
and may be superseded by updates. It is your responsibility to

The MCP2120/MCP2150 Developer’s Kit demonstrates the capabilities of the
MCP2120 and MCP2150 infrared communication products. The MCP2120 and
MCP2150 Developer’s Board can be connected to either a PC via the DB9 connector,
or to another system (such as a PICDEM™ 2 board) via the four pin header.
The MCP2120/MCP2150 Developer’s Kit comes with the following:
1. Two MCP2120 Developer Boards.
2. One MCP2150 Developer Board.
3. Two serial cables.
4. One 9V power supply, with power cord.
5. One pair 18” (45 cm) power jumper cables.
6. Sample kit (one MCP2120 device and one MCP2150 device) – not shown.
Each kit comes with one MCP2120 device and one MCP2150 device. This
allows a prototype system to be developed that can be used with an MCP2120
Developer’s Board or an MCP2150 Developer’s Board.
7. MCP2120/MCP2150 Developer’s Kit User’s Guide (This document) – not shown.

1.3.2 Selecting UART Source and Optical Transceiver Interface
Figure 1-2 shows two pairs of jumpers used to route signals to and from the MCP2120.
Jumpers J1 and J4 are used to determine the source of the signals used by the UART
interface. When the header has the pins closest to the “DB9” label jumpered to the
center pin, the DB9 is the source of the UART signal. When the header has the pins
closest to the “Header” label jumpered to the center pin, the four-pin header is the
source of the UART signal.
Jumpers J6 and J7 are used to determine the source and destination of the infrared
data signals used by the interface between the MCP2120 and Optical Transceiver.
When the header has the pins closest to the “Integrated Transceiver” label jumpered to
the center pin, the integrated transceiver is used. When the header has the pins closest
to the “Component Transceiver” label jumpered to the center pin, the component
transceiver logic is used.

In most cases, this jumper will be open. It may be closed to test system operation when
the MCP2120 is disabled. The Host Controller board may control the operation of the
MCP2120 by connecting a signal to the JP4 header as shown in Figure 1-6.

1.3.6 MCP2150 Developer’s Board Features
The MCP2150 Developer’s Board, as shown in Figure 1-7, has the following hardware
features:
1. On-board +5V regulator for direct input from 9V, 750 mA AC/DC wall adapter or
9V battery.
2. Hooks for a +5V, 750 mA regulated DC supply.
3. DB-9 connector and associated hardware for direct connection to MCP2150
UART (DB-9 interface requires RS-232 signal levels).
4. Ten-pin header connection to UART interface (Header requires TTL level
signals).
5. Three jumpers to select source of UART signals. Either DB-9 connector or the
eight-pin header.
6. Two jumpers to select desired baud rate.
7. Green power-on indicator LED.
8. Green LED for Carrier Detect.
9. Two IR Transceiver options (two jumpers select transceiver).
10. Jumper to disable MCP2150 device operation.
11. Hardware Baud selection.
Note: A schematic of the MCP2150 Developer’s Board is shown in Figure A.26
