1.2 SST’s ATA-Disk Chip Product Offering

The SST58SD/LDxxx ATA-Disk Chip product family is available in 8 to 192 MByte capacities. The following table

shows the specific capacity, default number of cylinder heads, sectors and cylinders for each product line.

2.0 ELECTRICAL INTERFACE

2.0.1 Pin Assignment and Pin Type

The signal/pin assignments are listed in Table 2-1. Low active signals have a “#” suffix. Pin types are Input, Output or Input/

Output. Section 2.3 defines the DC characteristics for all input and output type structures.

2.1 Electrical Description

The ADC functions in ATA Mode, which is compatible with IDE hard disk drives.

Table 2-2 describes the I/O signals. Signals whose source is the host are designated as inputs while signals that the ADC

sources are outputs. All outputs from the ADC are totem pole except the data bus signals which are in the bi-directional tri-

state. Refer to Section 2.3.2 for definitions of Input and Output types.
