CDP1020 Data Sheet April 1999 File Number 4704 SMBus/I 2C ACPI Dual Device Bay Controller The CDP1020 is an ACPI compliant Device Bay Controller (DBC) that can control two device bays. The controller interfaces to the host system through the industry standard I2C or System Management Bus (SMBus) and is fully compliant with Device Bay Speciﬁcation 0.90. The CDP1020 is designed to be compatible with the integrated SMBus host controller of the PiiX4/PiiX6 in Intel Architecture platforms. The CDP10.

CDP1020 Features

* of this device is the on-chip level shifters that provide slew rate controlled, direct gate drive for external N-Channel MOSFETs (Intersil HUF76113DK8 recommended) to switch the device bay VID supplies. Switching an N-Channel device as opposed to a P-Channel reduces both device cost and device count
