CY7C68300C/CY7C68301C
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.
