The Initio INIC-2430 provides an advanced solution to connect ATAPI or ATA (IDE/EIDE) devices to IEEE-1394a with integrated 32-bit CPU and embedded SRAM. To provide high performance and cost effective solution, the INIC-2430 integrates 1394a link core, ATA control block and microprocessor into a single ASIC. The INIC-2430 delivers the data transfer rate up to 800Mbits/sec on Firewire 800 (1394) interface (100Mbytes/sec), while its ATA interface supports ultra DMA modes (33/66/100/133 MB/sec).
