3 / 42 page HI-3210 HOLT INTEGRATED CIRCUITS 3 APPLICATION OVERVIEW The HI-3210 is a flexible device for managing ARINC 429 communications and data storage in many avionics applications. The device architecture centers around a 32K x 8 static RAM used for data storage, data filtering tables and table-driven transmission schedulers. Once configured, the device can operate autonomously without a host CPU, negating the need for software development or DO-178 certification. Configuration data may be uploaded into the device from an external EEPROM, following system reset. The device supports up to eight ARINC 429 receive channels. Received data is stored in on-chip RAM organized by channel number and label. The data table continually updates as new labels arrive. Programmable interrupts and filters alert the host subsystem to labels of interest. Each ARINC 429 receive channel also includes a 32 message deep FIFO allowing selected label data to be queued for subsequent host access. The HI-3210 includes four independent ARINC 429 transmit channels. Transmission may be controlled entirely by an external CPU, or autonomously by programming one or more of the four on-chip ARINC 429 transmit schedulers. These allow periodic transmission to occur without CPU. Source data for transmission may be selected from RAM based tables of constants and / or from the received channel data. Powerful options exist for constructing ARINC 429 labels as well as controlling their timing and conditional transmission. Even when running under the control of schedulers, the host CPU may insert new labels for transmission at will. The following examples show five possible configurations of how the HI-3210 may be used: Example 1.
