SX00-0B00-00

• I/O Expander with GPIO, SATA, and Serial Port Expansion
• I2C and UART Control Interfaces
• Three Ports
• 3.3V Operating Supply Voltage
• Broadcom FPB22GU Part Family
• REACH SVHC Substances Declared Present

The Broadcom SX00-0B00-00 is an I/O expander providing GPIO, SATA, and serial port expansion, managed over I2C and UART control interfaces. It presents three ports and operates from a 3.3V supply. The available attribute data for SX00-0B00-00 is limited to port count, supply voltage, and substance declaration, so package and timing details should be confirmed against the manufacturer datasheet before design-in.

An I/O expander adds ports to a host processor that has run out of pins, communicating over a low pin-count control bus such as I2C or UART rather than consuming the processor pins it is replacing. This is the standard way to add general-purpose I/O, status LEDs, board control signals, or additional device interfaces late in a design without moving to a larger and more expensive processor. Expanders that also handle SATA and serial expansion are typically found in storage and server hardware, where enclosure management, drive bay control, and console access all need port capacity. Because the published attribute set for this part is sparse, buyers should treat the datasheet as the authoritative source for electrical and mechanical specifications.
