Product Summary
The AF82801JDO-SLG8U is a data communications ic. The AF82801JDO-SLG8U distinguishes from other low level HDLC devices by its advanced characteristics. The most important are: Beyond the point-to-point configurations, the AF82801JDO-SLG8U directly enables point-to-multipoint or multimaster configurations without additional hardware or software expense. In point-to-multipoint configurations, the AF82801JDO-SLG8U can be used as a master as well as a slave station. Even when working as slave station, the AF82801JDO-SLG8U can initiate the transmission of data at any time. An internal function block provides means of idle and collision detection and collision resolution, which are necessary if several stations start transmitting simultaneously. These features were integrated to support multimaster configurations.
