Message Text: Seiko Epson today announced that it has developed the S1R72H74, a new ATA controller LSI suited for use in products with built-in hard disk drives.

Shipments of the new samples began this month, according to the Japanese company.

Epson already offers two controller LSI products?the S1R72V03 and the S1R72V05?which combine high-speed USB 2.0 and ATA functions. The new S1R72H74 ATA controller LSI supports and specializes in ATA/ATAPI-6 and is geared toward built-in devices. It also supports a wide operating temperature range.

With the S1R72H74, data can be transmitted back and forth between the main CPU and the hard disk. The package, pin configuration, and software are all compatible with the S1R72V03, a single-chip product combining high-speed USB 2.0 device and ATA controller functions which is already being produced for the volume market, allowing for continued use of existing resources such as boards and software provided they have a USB function.
