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. 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in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application meets with your specifications. MICROCHIP MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND WHETHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, STATUTORY OR OTHERWISE, RELATED TO THE INFORMATION, INCLUDING BUT NOT LIMITED TO ITS CONDITION, QUALITY, PERFORMANCE, MERCHANTABILITY OR FITNESS FOR PURPOSE. Microchip disclaims all liability arising from this information and its use. Use of Microchip devices in life support and/or safety applications is entirely at the buyer’s risk, and the buyer agrees to defend, indemnify and hold harmless Microchip from any and all damages, claims, suits, or expenses resulting from such use.

2.2 DEVICES

2.2.1 24LC02B 2Kbit Serial EEPROM

The 24LC02B is a 2Kbit Serial EEPROM. Refer to the 24AA02/24LC02B Data Sheet (DS21709) for complete information. The slave address is 0xAX (where x = any value).

Data can be read or written to the 24LC02B.

2.2.2 MCP9801 High-Accuracy Temperature Sensor

The MCP9801 is a High-Accuracy Temperature Sensor. Refer to the MCP9800/MCP9801 Data Sheet (DS21909) for complete information. The slave address is 0x92.

The temperature can be read from the MCP9801. Test points ALERT and GND provide signals that can be read using a voltmeter or oscilloscope.

2.2.3 MCP3221 Low-Power 12-Bit A/D Converter

The MCP3221 is a Low Power 12-Bit A/D Converter. Refer to the MCP3221 Data Sheet (DS21732) for complete information. The slave address is 0x9A.

Potentiometer R1 is configured as a voltage divider (see schematic in Appendix A. “Schematic and Layouts”). The wiper is connected to the input. The voltage can be read by the MCP3221 and can be verified using an volt meter on test points A

GND.

and

2.2.4 TC1321 10-Bit Digital-to-Analog Converter

The TC1321 is a 10-Bit Digital-to-Analog Converter. Refer to the TC1321 Data Sheet (DS21387) for complete information. The slave address is 0x90.

The V voltage swing (V

The output of the TC1321 can be measured using a volt meter at test points V DAC-OUT, and GND.

) will be between 0 - 2.5V.

OUT

2.2.5 MCP23008 8-Bit I/O Expander

The MCP23008 is an 8-bit I/O Expander. Refer to the MCP23008/MCP23S08 Data Sheet (DS21919) for complete information. The slave address is 0x40.

The output of the MCP23008 drives LEDs DS1 through DS8. The LEDs provide an easy to see indication of the MCP23008 operation. Jumper JP1 must be closed using a 2-pin shunt for the LEDs to operate. The LEDs can be disabled by removing JP1.

The output of the MCP23008 is connected to test points GP0 through GP7 and GND. These test points can be monitored by a volt meter or connected to an external device. LEDs DS1 through DS8 can be used to monitor the output by closing JP1 with a 2-pin shunt or disable by removing JP1.
