Applications

The VSC210 is an ideal Baseboard Management

Controller for server management applications.

The

VSC210 and related Software Development Kit (SDK)

implement the IPMI 1.0 specification for BMCs.

The

VSC210 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 VSC210 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 VSC210 includes three, I

controllers. These controllers may be used to interface

to off-the-shelf instrumentation and control devices

commonly

used

in

environmental

monitoring

and

management

applications

such

as

Vitesse's

SSC050/055 Backplane Controller. The controllers also

support

direct

connection

to

Intelligent

Platform

Management Buses (IPMB).

The VSC210 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

VSC210 has four external chip selects each with a one-

megabyte address range.

The VSC210 integrates three UARTs. One port may be

used as a firmware debug port.

A second port fully

implements the Intelligent Chassis Management Bus

(ICMB) defined by IPMI. A third, general purpose UART

is provided for maximum system design flexibility. The

Vitesse provided Software Development Kit includes

ROM Monitor and firmware download functionality via

the UARTs.

Software

The software designed to execute on the VSC210

determines the characteristics of the overall server

management

solution.

Most

server

management

applications will be unique to a customer's individual

product.

The VSC210 firmware architecture uses a

Personality Module with captures the unique functionality

required by a particular application. Vitesse provides a

Software Development Kit (SDK) to customers to assist

their development of their Personality Module.

The SDK includes software to implement KCS and

System Management Interface Chip (SMIC)

transport

and IPMI diagnostic environment. In addition, the SDK

also includes a System Services module with provides

APIs to the peripheral functionality (interrupts, timers

etc.) in the VSC210. The System Services also includes

driver libraries for popular I

LM75, LM78, and many others.
