2.6 EVALUATING THE 45X1 DIGITAL POTENTIOMETERS
The MCP45x1 is a family of digital potentiometers that offers 7- and 8-bit resistor net-
works as well as volatile and non-volatile memories options, in a MSOP 8-pin pack-
age.The MCP45X1 8-pin package is shown in
Figure 2-12 . The family works with an
I
2
C serial interface with speeds of 100 kHz, 400 kHz and 3.4 MHz. The PICkit Serial
Analyzer can be used to communicate with the devices. The proper connections are
being shown in
Figure 2-13 . Other Digital Potentiometers that are supported by this
evaluation board are shown in Table 2-6 .
