General Description
The M429T1R1 macro implements a synchronous single-chip ARINC 429 Transmit and Receive Controller Macro capable of linking one CPU to one ARINC 429 bus. The macro controls all ARINC 429 bus-specific sequences, protocol and timing. The M429T1R1 macro interface allows the parallel-bus microprocessor to communicate bidirectionally with the ARINC 429 bus. This macro can be customised according to specific needs (application-specific requirements). Any other pre-designed functions can be integrated into the FPGA. FPGA density and I/O requirements can be defined according to customer specifications.
