Pin Descriptions
The following table lists the pinouts for the 56-pin SSOP, 56-pin
QFN and 100-pin TQFP package options for the AT2LP. Refer
to the
“Pin Diagrams” on page 3
for differences between the
68300C/01C and 68320C/321C pinouts for the 56-pin
packages. For information on the CY7C68300A pinout, refer
to the CY7C68300A data sheet that is found in the ’EZ-USB
AT2’ folder of the
CY4615C reference design kit CD
.

Notes
1. If byte 8, bit 4 of the EEPROM is set to ‘0’, the ATA interface pins are only active when VBUS_ATA_EN is asserted. See
“VBUS_ATA_ENABLE” on
.
2. A ‘#’ sign after the pin name indicates that it is active LOW.
