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.

Preface
DOCUMENT REVISION HISTORY
Revision B (July 2006)
• Add disclaimer to Bill of Materials regarding RoHS-Compliant part numbers.
This chapter provides an overview of the MCP212X Developer’s Daughter Board and
covers the following topics:
• What is the MCP212X Developer’s Daughter Board?
• What the MCP212X Developer’s Daughter Board kit includes
1.2WHAT IS THE MCP212X DEVELOPER’S DAUGHTER BOARD?
The MCP212X Developer’s Daughter Board is used to evaluate and demonstrate the
MCP2122 or MCP2120 IrDA
®
Standard Encoder/Decoder device. This allows the
system designer to implement a low-cost, wireless IR port in any application providing
support for IrDA standard bit encoding/decoding.
The MCP212X Developer’s Daughter Board is designed to interface to several of the
“new” low-cost PICmicro
®
microcontroller-based demonstration (demo) boards, or to
be interfaced into your application. Multiple header interfaces are available that allow
support for the many different PICDEM™ Demo Boards, as well as being easily
jumpered into systems for development purposes. Table 1-1 shows some of the
PICDEM demo boards that are supported.
Depending on the features of the PICmicro Microcontroller Unit (MCU) and the
selected demo board, the MCP2122 TX and RX signals can either be connected
(jumpered) directly to the RS-232 line driver or to the PICmicro MCU’s RX and TX
signals. The PICmicro MCU could process that data and then send it out of the UART.
Note 1:Other boards may also be supported. Please refer to the MCP212X Developer’s Daughter Board and
desired PICDEM™ Demo Board documentation to determine if the boards you are using are supported.
2:For proper orientation of the daugter board to the PICDEM™ demo board, Revision 5 of the PICDEM™
HPC Explorer Board is recommended. Revision 4 will function, but the direction of the optical transceiver
will be facing the same side as the serial port connector.
3:The MCP212X Developer’s Daughter Board allows the MCP212X TX and RX signals to be routed to
different header connections. This may allow the system to support multiple configurations, such as being
either connected to the PICmicro
communicate via the DB-9 connector).

The major components for the MCP212X Developer’s Daughter Board are:
1.MCP2122 device (U4).
2.MCP2120 device socket (U1).
3.Optical transceiver (U5 – Vishay TFDU 4300).
4.Headers H1 and H2.
5.Header H3.
6.Header HD1.
7.Jumpers to route the TX, RX and 16XCLK signals.
8.Jumpers to select the baud rate and mode.
9.Footprint for two different optional optical transceiver circuits
(Vishay TFDU 4100 and Agilent HSDL 3000).
10. MCP2120 crystal (Y2).
The MCP212X Developer’s Daughter Board is assembled and tested to allow for the
evaluation and demonstration of the MCP2122 or MCP2120 features. A schematic of
the circuit, as well as the corresponding PCB layout, is shown in Appendix A. “Schematic and Layouts”. Appendix B. “Bill Of Materials (BOM)” shows two
tables; the first is the components that are installed, while the second lists the optional
components that are not installed.
The component layout floor plan is shown in Figure 2-1.
