Page 8: Evaluation Board Hardware
UM0529 Evaluation board hardware All the hardware components except the transceiver IC are the same for the STUSB02E and STUSB03 evaluation boards. The evaluation boards are comprised of one mini-B USB connector, one USB controller, one USB transceiver, two 2-to-4 demultiplexers and all required discrete components (pull-up resistors, series resistors and power supply capacitors). -
Page 9: Evaluation Board Components
STUSB02E/STUSB03E transceiver U5 The STUSB02E and STUSB03 are single chip USB transceivers that support both USB full- speed and USB low-speed operations. Both have an integrated 5 V to 3.3 V regulator which allows direct powering from the VBUS. -
Page 10: Ld2985Bm33R Voltage Regulator U4
LD2985BM33R usage is optional in the board. By configuring jumpers J9,J13,J11, the external voltage regulator can be switched off. In this case, the internal voltage regulator of the microcontroller is used to power 74LCX139MTR and STUSB02E/ STUSB03 V When external voltage regulator LD2985BM33R is used for powering 74LCX139MTR and STUSB02E/ STUSB03 V , overall current consumption of the board increases. -
Page 11: Power Requirements
UM0529 Power requirements Power requirements The recommended supply voltages for the STUSB02E/STUSB03E USB transceivers are the following: = 1.6 - 3.6 V (typical value: V = 1.8 V) = 4.0 - 5.5 V (typical value: V = 5 V) The V for the USB transceiver can be obtained from the onboard voltage regulator as well as the built-in voltage regulator of the ST72F63B. -
