DEI3093-MES-G

The DEI3093 is an ARINC 429 transceiver (2RX/1TX) CMOS integrated circuit. It provides the interface between an ARINC 429 avionics data bus and a Serial Peripheral Interface (SPI) enabled host such as a microcontroller or ASIC. The four SPI control/data signals are CMOS/TTL compatible. The IC operates from a single 3.3V power supply.

Functional Description

The DEI3093 is an ARINC 429 transceiver (2RX/1TX) CMOS integrated circuit. It provides the interface between an ARINC 429 avionics data bus and a Serial Peripheral Interface (SPI) enabled host such as a microcontroller or ASIC. The four SPI control/data signals are CMOS/TTL compatible. The IC operates from a single 3.3V power supply.

The ARINC 429 interface comprises two receivers and one transmitter. Each receiver offers user-programmable label recognition for up to 256 possible labels, a 32 x 32 Receive FIFO, three Priority Label quick-access single-buffered registers and an on-chip analog line receiver. The RX inputs in conjunction with external 40K
