3.0 ATA Interface

The drives use an ATA-3 interface. The interface complies with ANSI ATA (AT Attachment) Interface X3T10 Rev. 6.0; SFF 8011: ATA Timing Extension for Local Bus Attachments, Rev. 2.0 and SFF 8019: Identify drives Data for drives Under 8 GB. The ATA commands that the drives support are listed on pages 27 and 28. Commands and features with specific applications for these drives are also discussed in this section.

The ATA interface consists of single-ended, TTL-compatible receivers and drivers that use an asynchronous interface protocol. The drivers can sink up to 24 mA and drive a load up to 300 pF. The integrity of the ATA interface is affected by the interface cable. It is designed to support a 40-conductor, nonshielded interface cable with a maximum length of 18 inches (46 centimeters).

3.1 ATA Interface connector pin assignments

The signal name and signal direction for each I/O connector pin is shown in Figure 7 on page 26. See the Seagate ATA Interface Reference Manual, publication number 36111-xxx, for a complete description of each pin.

Signal names are shown in upper-case letters. If the signal name is followed by a minus sign (–), the signal is active low. Otherwise, the signal is active high.
