Compatibility

The ATA5577 is designed to be compatible with the T5557/ATA5567. The structure of the con-

figuration register is identical. The two modes, Basic mode and Extended mode, are also

available. The ATA5577 is able to replace the e5551/T5551 in most common operation modes.

In all applications, the correct functionality of the replacements must be evaluated and proved.
