5 Description (continued)

The FPC401 is compatible with standard SFF-8431, SFF-8436, and SFF-8449 low-speed management interfaces, including a dedicated 100-kHz and 400-kHz I2C interface to each port. Additional general-purpose pins are available to perform functions such as driving port status LEDs or controlling power switches. The LED drivers have convenience features such as programmable blinking and dimming. The interface to the host controller can operate on a separate supply voltage between 1.8-V and 3.3-V to support low-voltage I/Os.

The FPC401 can prefetch data from user-specified registers in each module, making the data readily accessible to the host through a fast I2C (up to 1 MHz) or SPI (up to 10 MHz) interface. In addition, the FPC401 can trigger an interrupt to the host whenever critical, user-configurable events occur associated with any of the ports under its control. This eliminates the need to continuously poll the modules.
