DESCRIPTION
The PCA9558 is a highly integrated, multi-function device that is
composed of a 5-bit multiplexed/1-bit latched 6-bit I
2
C/SMBus
EEPROM, an 8-bit I/O expander and a 2K serial EEPROM with write
protect. The PCA9558 integrates these commonly used components
into a single chip to reduce component count and board space
requirements and is useful in computer, server and
telecom/networking applications.
Multiplexed/latched EEPROM —
used to select digital information
between a set of 5-bits of default hardware inputs and an alternative
set of inputs provided by the I
2
C/SMBus interface and stored in the
EEPROM. Examples of this type of selection include processor
voltage configuration or processor vendor identification (VID). The
multiplexed/latched EEPROM can also be used to replace DIP
switches or jumpers, since the settings can be easily changed via
I
2
C/SMBus without having to power down the equipment to open the
cabinet. The non-volatile memory retains the most current setting
selected before the power is turned off.
8-bit I/O expander —
used to control, monitor or collect remote
information or power LEDs. Monitored or collected information can
be read through the I
2
C/SMBus or can be stored in the internal
EEPROM.
2K serial EEPROM —
used to store information such as card
identification or revision/maintenance history on every
motherboard/linecard and can be read or written via I
2
C/SMBus
when required.
The PCA9558 has 1 address pin allowing up to 2 devices to be
placed on the same I
2
C bus or SMBus.
