Pin Functions

over operating free-air temperature range (unless otherwise noted)

(1) Applies to external inputs and bidirectional buffers.

(2) Applies to external outputs and bidirectional buffers.

(3) Applies to GRSTz.

Spacer

(4) Applies to pins with internal pullups/pulldowns.

(5) Applies to external input buffers.

7.6 Timing Requirements, Power-Up

(1) An active reset is required if the VDD33 supply is stable before the VDD11 supply. This active Reset shall meet the 3ms power-up delay counting from both power supplies being stable to the de-assertion of GRSTz.

(2) There is no power-on relationship between VDD33 and VDD unless GRSTz is only connected to a capacitor to GND. Then VDD must be stable minimum of 10 μs before the VDD33.

(3) MISC pins sampled at de-assertion of GRSTz: FULLPWRMGMTz, GANGED, PWRCTL_POL, SMBUSz, BATEN[4:1], and AUTOENz.

Figure 2. Power-Up Timing Requirements

over operating free-air temperature range (unless otherwise noted)

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

over operating free-air temperature range (unless otherwise noted)

(1) A 1.05-V, 1.1-V, or 1.2-V supply may be used as long as minimum and maximum supply conditions are met.

(2) The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard, high-K board, as specified in JESD51-7, in an environment described in JESD51-2a.

(3) The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDECstandard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

(4) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8.

(5) The junction-to-top characterization parameter, ψJT, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining RθJA, using a procedure described in JESD51-2a (sections 6 and 7).

(6) The junction-to-board characterization parameter, ψJB, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining RθJA, using a procedure described in JESD51-2a (sections 6 and 7).

(7) The junction-to-case (bottom) thermal resistance is obtained by simulating a cold plate test on the exposed (power) pad. No specific JEDEC standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

The TUSB8041 is a four-port USB 3.0 compliant hub. It provides simultaneous SuperSpeed USB and highspeed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or low speed connections on the downstream port. The TUSB8041 can be used in any application that needs additional USB compliant ports. For example, a specific notebook may only have two downstream USB ports. By using the TUSB8041, the notebook can increase the downstream port count to five.
