Chapter 1 Required Hardware and Software The TUSB3410 general-purpose input-output EVM was designed for use with a personal computer running a USB-enabled operating system. The PC should be USB 1.1 or USB 2.0 spec compliant. This implies the BIOS, chipsets, and operating system are all spec compliant. If the BIOS is not spec compliant, the system may not boot when USB devices are connected at power up and the EVM may not function. Note that the EVM can only function in the bus-powered mode.
Hardware Items 1.1 Hardware Items The TUSB3410 EVM is shown in Figure 1, together with typical representations of the hardware items required for its use. Figure 1–1.
Hardware Overview 1.2 Hardware Overview The TUSB3410 GPIO EVM hardware platform is 4,3 cm × 6,8 cm in width × length. Throughout this document, text inside of parentheses (ex.) is reference designators found on the TUSB3210 EVM. See Figure 1–2 for a reference picture of the EVM. First, all jumpers are installed with the factory settings. See Table 2–3 for a description of jumper settings and make any required changes before using the EVM.

TUSB3410 EVM Setup 2.1 TUSB3410 EVM Setup The TUSB3410 general-purpose EVM is designed to support many USB applications. The EVM comes in a default configuration that requires no additional components on the EVM. A full description of the TUSB3410 device is specified in the data manual. The PC must be running a USB-capable operating system. Configure the EVM if required, based on desired settings specified later in this section.
Jumpers 2.6 Jumpers Table 2–3 is provided to help set up and configure the EVM platform jumpers for the desired mode of operation. The EVM can download firmware code from the PC through a loading program (may or may not be supplied with your EVM) or from an I2C EEPROM. JP2 and JP3 are used to connect P3.0 and P3.1 to D3 and D4 respectively. JP4 is for separating the SCL pin of the I2C EEPROM from SCL of the TUSB3410. Table 2–3.
