CY7C68320C/CY7C68321C

AC Electrical Characteristics

ATA Timing Characteristics

The ATA interface supports ATA PIO modes 0, 3, and 4, Ultra DMA modes 2, 3, and 4, and multi-word DMA mode 2, per the ATA/ATAPI 6 Specification. The highest enabled transfer rate common to both the AT2LP and the attached mass storage device is used. The AT2LP automatically determines the transfer rates during drive initialization based upon the values

in the AT2LP configuration space and the data reported by the drives in response to an IDENTIFY DEVICE command.

USB Transceiver Characteristics

Complies with the USB 2.0 specification for full- and high-speed modes of operation.
