General Description
The VSC215 is an embedded controller tailored for Intelligent Platform Management Interface (IPMI)
Baseboard Management Controller (BMC) applications. The feature set selection and flexibility of this device
makes it the perfect BMC solution for entry through high-end servers. No additional logic is required to inter-
face the VSC215 into Intel-Architecture (IA) servers and workstations supporting LPC or X-Bus. Four I2C
serial multi-master controllers and three UARTs allow system designers to mix and match IPMB, ICMB and
private I2C configurations to best meet the requirements of a particular system. The VSC215 includes a high
performance, 32-bit RISC processor, which provides the processing bandwidth and addressability required for
sophisticated platform management strategies. The Software Development Kit (SDK) and evaluation board
allow for reduced development cycles, high code reuse between implementations and faster time-to-market.
