2.3 Theory of Operation for SM-USB-DIG Platform
Figure 4 shows the block diagram for the SM-USB-DIG Platform. This platform is a general-purpose data
acquisition system that is used on several different Texas Instruments' evaluation modules. The details of
its operation are included in a separate document. The block diagram shown in Figure 4 is given as a brief
overview of the platform.
The core of the SM-USB-DIG Platform is the TUSB3210, an 8052 microcontroller (μC) that has a built-in
USB interface. The microcontroller receives information from the host computer that it translates into
power, I

C, SPI, or other digital I/O patterns. During the digital I/O transaction, the microcontroller reads
the response of any device connected to the I/O interface. The response from the device is then sent back
to the PC where it is interpreted by the host computer.

3.1 Electrostatic Discharge Warning
CAUTION
Many of the components on the AMC80EVM are susceptible to damage by
electrostatic discharge (ESD). Customers are advised to observe proper ESD
handling precautions when unpacking and handling the EVM, including the use
of a grounded wrist strap at an approved ESD workstation.
