BCM5770R - 4-Port SATA/PCI-X® Controller

4-Port SATA/PCI-X® Controller

The BCM5770/BCM5770R is a highly integrated, multiport SATA-I controller that has been designed for high performance storage applications requiring low host CPU utilization and maximum I/O performance.

The device communicates with the host via a 64-bit, 133-MHz PCI-X1.0 bus interface. It attaches directly to a maximum of eight SATA-I disk drives or to backplanes on the target side via a high-performance, integrated SATA PHY that is capable of driving long-length backplanes. Additionally, the BCM5770/BCM5770R supports hot-plug capability, enabling SATA disk drives to be inserted and removed from a storage rack or server without affecting system operation.

  • Industry's first 0.13μ CMOS SATA-I Controllers
  • Octal (BCM5770) and quad (BCM5770R) ports
  • Enclosure management support
  • Octal and quad versions are pin-compatible
