AEK-USB-2TYPEC1 STMicroelectronics

AEK-USB-2TYPEC1 Data brief USB Type-C and Power Delivery dual port interface board with automotive- grade STUSB1702Y USB Type-C controller Features Both ports acting as Provider role Type-C attach and cable orientation detection High voltage protections on VBUS and CC lines V switch gate drivers BUS V monitoring and discharge path BUS A current sensing circuit for each port on VBUS line Power connector to interface with external power boards (not included) Total board dimensions: 85 mm x 81 mm RoHS compliant Description The AEK-USB-2TYPEC1 automotive grade USB Type-C and Power Delivery dual port expansion board is part of the ST AutoDevKit development initiative. It embeds two STUSB1702Y USB Type-C port controllers for a two-port Provider solution. Each STUSB1702Y USB Type-C port controller includes a fully-featured USB type-C state machine for attach/detach and cable orientation detection, a USB PD PHY and BMC transceiver, high voltage (20 V) technology V voltage monitoring, 600 mA BUS VCONN power switch, VBUS and VCONN discharge paths, 22 V CC line protection, VBUS switch gate drivers and data role configuration (not used in this case). The two USB Type-C ports have USB 2.0 data lines that are accessible through on- board connectors J101 and J102. The same connectors may be used to redirect the Product summary data from one of the two USB 2.0 ports to the 4x20 pass-through connector. dual-port USB Type-C AEK- function board USB-2TYPEC1 The board also has a power status LED and three status LEDs to signal what each Type-C port is advertising: power role, VBUS negotiation status and CC line evaluation kit with orientation (direct or flipped). Two alternate function connectors (not mounted) are dual-port USB Type-C AEKD- available for extension or future developments. function board and USBTYPEC1 SPC58 Chorus The AEK-USB-2TYPEC1 board is designed to be connected to a SPC58 Chorus discovery board 4 MB flash discovery board (SPC58EC-DISP) equipped with a 32-bit Power automotive grade USB Architecture microcontroller for automotive ASIL-B applications. The AEKD- Type-C controller (with USBTYPEC1 kit consists of two boards and a USB-PD firmware package, so you can STUSB1702Y Tx/Rx line driver and develop application based on the USB-PD Provider role. BMC) The AEK-USB-2TYPEC1 embeds a connector for an external power board, which firmware package for STSW- would allow the system to deliver output voltage profiles up to 20 V and satisfy the AEKD- USB2TYPEC1 various power requests according to the USB Power Delivery specification.
