User’s Guide

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.

Chapter 1. Product Overview

1.1 INTRODUCTION

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

1.2 WHAT 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).

Chapter 2. Installation and Operation

2.1 INTRODUCTION

This chapter discusses the operation of the MCP212X Developer’s Daughter Board and how it can be used in conjunction with some of Microchip’s low-cost PICDEM™ Demo Boards or easily connected to your system.

When the MCP212X Developer’s Daughter Board is used in conjunction with one of the low-cost PICDEM™ Demo Boards, it demonstrates the implementation of an embedded system with an IrDA A second encoder/decoder system is required to demonstrate system operation.

The Host UART interface includes only the TX and RX signals. A discussion of the Host UART interface is given in the following application note:
