Product Brief

VSC215

Applications

The VSC215 is an ideal Baseboard Management Controller for server management applications. The

VSC215 and related Software Development Kit (SDK) implement the IPMI 1.0/1.1 specification for BMCs.

The VSC215 may also be used in applications other than IPMI through firmware modifications.

Architecture

System Level Integration (SLI) techniques were used to create a complete system on a chip. The VSC215 is

based on Vitesse’s proven architecture for enclosure and platform management solutions. It integrates an

embedded RISC processor, a flexible system interface, memory and multiple peripheral interfaces to create an

embedded system for server platform management.

The VSC215 includes four, I2C multi-master bus controllers. These controllers may be used to interface to

off-the-shelf instrumentation and control devices commonly used in environmental monitoring and manage-

ment applications such as Vitesse's SSC050/VSC055 I2C Backplane Controllers. The controllers also support

direct connection to Intelligent Platform Management Buses (IPMB).

The VSC215 requires off chip memory for firmware code storage. Most applications will use flash memory

devices for non-volatile storage. Static RAM may be added for higher performance applications. The VSC215

has four external chip selects each with a one-megabyte address range.

The VSC215 integrates three UARTs. One port can be used to control a modem. A second port fully imple-

ments the Intelligent Chassis Management Bus (ICMB) defined by IPMI. A third could be used as a Serial-ICE

interface for firmware debug and development. The Vitesse provided Software Development Kit includes ROM

Monitor and firmware download functionality via the UARTs.
