Theory of Operation for SDM-USB-DIG Platform

The SDM-USB-DIG platform is a general-purpose data acquisition system that is used on select TI EVMs.

The core component of the platform is the MSP430F5528, an ultra-low power 16-bit MCU. The
microcontroller receives information from the host PC and translates it into I

2

C, SPI, or other digital I/O

patterns. The connected device (in this case, the AMC7832 device) connects to the I/O interface of the
platform. During digital I/O transactions, the platform obtains information from the AMC7832 device and
sends to the host PC for interpretation. A block diagram of the platform is shown in

.
