PCA9558

8-bit I²C-bus and SMBus I/O port with 5-bit multiplexed/1-bit

latched 6-bit I²C-bus EEPROM DIP switch and 2-kbit EEPROM

Rev. 5 — 25 June 2012

Product data sheet

1. General description

The PCA9558 is a highly integrated, multi-function device that is composed of a 5-bit

multiplexed/1-bit latched 6-bit I²C-bus/SMBus EEPROM DIP switch, an 8-bit I/O expander

and a 2-kbit 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 DIP switch — used to select digital information

between a set of 5 bits of default hardware inputs and an alternative set of inputs

provided by the I²C-bus/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 I²C-bus/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 I²C-bus/SMBus or

can be stored in the internal EEPROM.

• 2-kbit serial EEPROM — used to store information such as card identification or

revision/maintenance history on every motherboard/line card and can be read or

written via I²C-bus/SMBus when required.

The PCA9558 has one address pin, allowing up to two devices to be placed on the same

I²C-bus or SMBus.

2. Features and benefits

 5-bit 2-to-1 multiplexer, 1-bit latch DIP switch

 6-bit MUX_OUTx and NON_MUXED_OUT EEPROM programmable and readable via

I²C-bus

 5 V tolerant open-drain MUX_OUTx and NON_MUXED_OUT outputs

 Active LOW override input forces all MUX_OUTx outputs to logic 0

 I²C-bus readable MUX_INx inputs

 5 V tolerant open-drain IOx pins, power-up default as outputs

 One address pin, allowing up to two devices on the I²C-bus

 Active LOW reset input with internal pull-up for the eight I/O pins

 2048-bit EEPROM programmable and readable via the I²C-bus or I/Os

 Operating power supply voltage range of 3.0 V to 3.6 V

 SMBus compliance with fixed 3.3 V levels
