Datasheet AS8223 FlexRay Active Star Device 1 General Description This document is subject to change without notice. The AS8223 is a monolithic FlexRay compliant Active Star Device that manages communication traffic among four FlexRay branches of the network, expandable to more branches through an Interstar interface. The four branches of the AS8223 operate as a FlexRay receiver and transmitter wherein one of the communication paths operates as a receiver while the rest operate as a transmitter. Additionally, the AS8223 comes with a Host Controller Interface to achieve active control of the power modes and error diagnosis. An autonomous mode is entered automatically, in which the device operates without the need for a host controller. A Communication Controller interface is also built into the AS8223, to provide the standard transceiver functionality on the ECU using the AS8223. The product is available in 44-pin MLF 9x9 package. 2 Key Features Active Star Device with four branches Message forwarding on six communication paths Communication Controller Interface, four FlexRay branches, Interstar Interface Data transfer up to 10Mbps Excellent EMC performance Low susceptibility to EMI Interface with optional bus guardian for bus supervision Automatic thermal shutdown protection Supports 12V and 24V systems with low sleep current Integrated power management system Two INH pins for the external voltage regulators control Local wake-up input Remote wake-up capability via FlexRay bus Supports Autonomous Power Mode and Host Controlled Power Mode management Supports 2.5V, 3V, 3.3V and 5V microcontrollers automatically adapts to interface levels VCC supply voltage buffer for fail-safe conditions Protection against damage due to short circuit conditions on the FlexRay branches positive and negative battery voltage Operating ambient temperature range -40ºC to +125ºC RoHs compliant 44-pin MLF 9x9 package 3 Applications The AS8223 FlexRay Active Star Device is tailored for automotive gateways with embedded FlexRay Active Star functionality.
