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
BUS
voltage monitoring, 600 mA
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).
Product summary
dual-port USB Type-C
function board
evaluation kit with
dual-port USB Type-C
function board and
SPC58 Chorus
discovery board
AEK-
USB-2TYPEC1
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
data from one of the two USB 2.0 ports to the 4x20 pass-through connector.
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
orientation (direct or flipped). Two alternate function connectors (not mounted) are
available for extension or future developments.
The
AEK-USB-2TYPEC1
board is designed to be connected to a SPC58 Chorus
4 MB flash discovery board (SPC58EC-DISP) equipped with a 32-bit Power
Architecture
®
microcontroller for automotive ASIL-B applications. The
AEKD-
USBTYPEC1
kit consists of two boards and a USB-PD firmware package, so you can
develop application based on the USB-PD Provider role.
The
AEK-USB-2TYPEC1
embeds a connector for an external power board, which
would allow the system to deliver output voltage profiles up to 20 V and satisfy
various power requests according to the USB Power Delivery specification.
