SLLSE09J November 2009 – July 2021 TUSB1210
PRODUCTION DATA
The TUSB1210 device includes a universal serial bus (USB) on-the-go (OTG) transceiver that supports USB 480 Mb/s high-speed (HS), 12 Mb/s full-speed (FS), and USB 1.5 Mb/s low-speed (LS) through a 12-pin UTMI+ low pin interface (ULPI).
LS device mode is not allowed by a USB2.0 HS capable PHY, therefore it is not supported by TUSB1210. This is stated in USB2.0 standard Chapter 7, page 119, second paragraph: “A high-speed capable upstream facing transceiver must not support low-speed signaling mode..” There is also some related commentary in Chapter 7.1.2.3.
