As long the device is not fully qualified, the parameters are not characterized in the means that parameters may change or can be updated during final product qualification and characterization. This document shows the objective of the AS8220A and this document is subjected to change without notice. The AS8220A is a high-speed automotive transceiver for fault tolerant and high speed applications, operating as the bi-directional interface between a generic communication controller and the twisted pair copper wires. The device enables two-way communication with the microcontroller with full mode handling, including the low-power modes. The transmission rates up to 10Mbps as well as the implemented Bus Guardian interface enables this transceiver the usage in fault tolerant and hard real-time applications in the stringent automotive environment. An extended diagnostic interface, offers advanced busfailure detection capabilities with the intelligent combination of bus-current measurement and logical comparators. A thermal sensor circuit with an integral shutdown mechanism prevents damage to the device in extreme temperature conditions. The symmetrical transient control for the high- and low-side driver for both the busminus and bus-plus line allows an idea...
