2.1 SM-USB-DIG Platform Description

Figure 2-2 shows the block diagram for the SM-USB-DIG platform. This platform is a general-purpose data acquisition system that is used on other Texas Instruments evaluation modules. The details of operation are included in a separate document, SBOU098 (available for download at www.ti.com).

The TUSB3210 is the primary control device for the SM-USB-DIG Platform. The TUSB3210 is an 8052 microcontroller that converts data received on the built-in USB interface to the I2C, SPI, and other serial digital I/O patterns. This EVM uses the I2C interface of the TUSB3210 to control the INA260.

Power supply for the SM-USB-DIG is derived from the USB interface. The SM-USB-DIG includes an onboard low dropout (LDO) regulator that uses the 5-V USB supply from the computer to generate a 3.3-V supply, which is then used to power all the active circuitry on board. The 3.3-V regulated supply can also be used to power the EVM PCB. In fact, the raw 5-V USB supply as well as the 3.3-V regulated supply are routed to a 2-input power MUX on the SM-USB-DIG, the TPS2115A, whose output terminates at the VDUT pin of the 10-pin EVM connector, intended to be used as the EVM power supply. The user can select between the 5-V and 3.3-V options for VDUT through the INA260EVM GUI software.
