JAJSDH9D August 2017 – May 2019 TUSB1042I
PRODUCTION DATA.
The TUSB1042I is in GPIO configuration when I2C_EN = “0”. The TUSB1042I supports USB 3.1 operation. The TEST1 pin needs to be pulled down to GND. CTL0 pins enables or disables USB 3.1 operation as detailed in Table 2.
After power-up (VCC from 0 V to 3.3 V), the TUSB1042I defaults to USB3.1 mode. The USB PD controller upon detecting no device attached to Type-C port or USB3.1 operation not required by attached device must take TUSB1042I out of USB3.1 mode by transitioning the CTL0 pin from L to H and back to L.
CTL0 PIN | FLIP PIN | TUSB1042I CONFIGURATION |
---|---|---|
L | L | Power Down |
L | H | Power Down |
H | L | One Port USB 3.1 - No Flip |
H | H | One Port USB 3.1 – With Flip |
Table 3 Details the TUSB1042I’s mux routing. This table is valid for both I2C and GPIO configuration modes.
