TUSB6250 Firmware Programmer User's Guide
TUSB6250 device requires EEPROM firmware storage. This EEPROM read device power code executed from internal RAM. TUSB6250-based storage device have firmware upgraded bus. This feature allows end-user field upgradeability. This function requires firmware version 00.00.01.10.x later. driver also required execute this function. When update initiated, TUSB6250 firmware firmware update mode. firmware disconnects from USB, then reconnects with different PID. This causes FWUpdate driver load. this point, application send data device through this driver. This chapter describes application.

During suspend, ATA/ATAPI device powered down. AT_IORDY signal remains pulled high during suspend, then current flows back ATA/ATAPI device increasing power consumption. prevent increased power consumption bus-powered design, AT_IORDY should pulled high through resistor controlled PWR500 (P2.2) terminal TUSB6250 firmware should enable internal pulldown resistors ATA/ATAPI signals during suspend. reference design available. order obtain valid suspend current measurement TUSB6250 each version demonstration boards, following modifications must completed:
