3.5 BMC Controller
The Integrated Baseboard Management Controller (Integrated BMC) is a highly integrated
single-chip solution, integrating several devices typically found on servers. The Integrated BMC
is mainly targeted at next generation servers, and provides a highly integrated server class
product.
The Integrated BMC contains the following integrated subsystems and features.
Server Class Super I/O functionality includes
• Keyboard style/BT interface for BMC support
• Two Fully Functional Serial Ports, compatible with the 16C550
• Serial IRQ Support
• SMI/SCI/PME Support
• ACPI Compliant
• Up to 16 Shared GPIO ports
• Programmable Wake-up Event Support
• Plug and Play Register Set
• Power Supply Control
• Watchdog timer compliant with Microsoft* SHDG
• LPC to SPI bridge for system BIOS support
• Real Time Clock module with the external RTC interface
