DEVICES
2.2.1
25LC020A 2K SPI Bus Serial EEPROM
The 25LC020A is a 2Kbit Serial EEPROM. Refer to the 25AA020A/25LC020A Data
Sheet (DS21833) for complete information.
Data can be read or written to the 25LC020A.
2.2.2
TC77-5.0 Thermal Sensor with SPI Interface
The TC77 is a serially accessible digital temperature sensor. Refer to the TC77 Data
Sheet (DS20092) for complete information.
The temperature can be read from the TC77.
2.2.3
MCP3201 2.7V 12-Bit A/D Converter with SPI Serial Interface
The MCP3201 is a successive approximation 12-bit Analog-to-Digital Converter with
on-board sample and hold circuitry. Refer to the MCP3201 Data Sheet (DS21290) for
complete information.
The device provides a single pseudo-differential input. Potentiometer R6 is configured
as a voltage divider (see schematic in Appendix A. “Schematic and Layouts” ). The
wiper is connected to IN+. The voltage can be read by the MCP3201 by grounding IN-
with a test lead and can be verified using a volt meter on test points IN+ and GND.
2.2.4
MCP4822 12-Bit DAC with Internal Vref and SPI Interface
The MCP4822 is a 12-Bit Digital-to-Analog Converter (DAC). Refer to the
MCP4821/MCP4822 Data Sheet (DS21953) for complete information.
The output of the MCP4822 can be measured using a volt meter at test points V OUTA ,
V OUTB , and GND.
2.2.5
MCP41010 Single/Dual Digital Potentiometer with SPI Interface
The MCP41010 is a single 10 k Ω digital potentiometer. Refer to the
MCP41XXX/42XXX Data Sheet (DS11195) for complete information.
The resistance of the digital potentiometer can be measured using an ohm meter at test
points P A0 , P W0 , P B0 , and GND.
2.2.6
MCP6S92 Single-Ended, Rail-to-Rail I/O, Low-Gain PGA
The MCP6S92 is a single-ended programmable gain amplifier (PGA). Refer to the
MCP6S91/2/3 Data Sheet (DS21908) for complete information.
The gain of the PGA can be measured by applying a signal to inputs CH0 or CH1 and
GND, and measuring the output on test points Vout and GND.
2.2.7
MCP23S08 8-Bit I/O Expander with Serial Interface
The MCP23008 is an 8-bit I/O Expander. Refer to the MCP23008/MCP23S08 Data
Sheet (DS21919) for complete information.
The output of the MCP23S08 drives LEDs DS1 through DS8. The LEDs provide an
easy to see indication of the MCP23S08 operation. Jumper JP8 must be closed using
a 2-pin shunt for the LEDs to operate. The LEDs can be disabled by removing JP8.
The output of the MCP23S08 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 JP8 with a 2-pin
shunt or disable by removing JP8.
