MG9081 Controller

Low Cost, Compact SoC for up to 8 Drives


The MegaRAC MG9081 BPC manages LED patterns for up to 8 SAS/SATA drives, providing drive activity, fail/rebuild and locate signals. A single controller supports SGPIO, SES2, and IPMI/IPMB without using any companion chip. It also does not require many typical components such as external crystal, flash memory, regulator, EEPROM, LED Driver, FRU, or transceivers - for reduced cost, simpler designs and improved time to market (TTM).

The MG9081 can be utilized in a multitude of designs, managing LEDs for systems that feature anywhere from 6 to 32 drives. A wide variety of reference designs are already available from AMI for simple integration into existing and future projects.
