System management continues to gain importance in the design of all electronic systems. Smaller process geometries drive more multi-volt devices and are more susceptible to voltage and temperature fluctuations. While system management designs can run into hundreds of discrete components, the Actel Fusion PSC solution can integrate these system management functions and provide programmable flexibility and system-level integration—all in a single chip. Unprecedented integration in Fusion devices can offer cost and space savings of 50% or greater relative to current implementations.

Actel, the world leader of programmable system chips (PSC), now offers the only single-chip system management solution. The Actel Fusion PSC integrates configurable analog, large flash memory blocks, comprehensive clock generation and management circuitry, and high performance programmable logic in a monolithic device. Actel has developed turn-key solutions, including a development kit and a software GUI for system management. This level of integration, configurability, and support establishes Fusion as the definitive system management solution.

System Management in a Single Chip

Actel Fusion PSC integrates mixed-signal analog front-end, flash memory, and programmable logic fabric in a monolithic PSC. The Actel Fusion devices enable designers to quickly move from concept to completed design and deliver feature-rich systems to market. This new technology takes advantage of the unique properties of Actel flash-based FPGAs, including a high-isolation, triple-well process, and the ability to support high voltage transistors to meet the demanding requirements of mixed-signal system design.

Fusion sets the standard in system management as the market's only single-chip solution. Leveraging a unique combination of flash memory, configurable analog, and flash programmable logic, Fusion reduces cost, board space, and design time.

The Fusion device's flexibility enables users to implement proprietary or standards-based system management solutions. As a single-chip implementation, Fusion simplifies design implementation, enabling all system management functions to be configured in a single design environment with increasing reliability.

The Actel Fusion-based System Management Development Kit provides an excellent platform for developing system management applications and/or applications with a microprocessor. The kit includes an ARM-enabled Fusion device, a system management GUI, and a platform for systems that performs these functions:

• Power-up detection
• Power sequencing
• Thermal management
• Sleep modes
• System diagnostics
• Remote communications
• Clock generation and management

The board includes an M1AFS1500 device, which is compatible with Cortex-M1, Core8051, and other processors, as well as non-processor-based implementations. The kit's demonstration design uses the MicroC/OS-II on Cortex-M1 with the system management GUI, which is multi-tabbed for board status, application data, IPMI data, and a graphical display of the monitored analog data. In addition, the GUI source code is available for custom modification.

All-Inclusive and Low Cost

The low cost Fusion Starter Kit contains everything you need to start using the advanced features of the Actel Fusion family:

• Evaluation Board with an AFS600-FG256 Fusion Device
• Actel Libero Integrated Design Environment (IDE) Gold
• FlashPro3 and Programming Cable
• Power Supply
• User's Guide Including Printed Circuit Board (PCB) Schematics

The board is designed to allow users to easily implement System Management Functions. The on-board voltage regulation, enables you to independently set the I/O voltages to 1.5 V or 3.3 V on each of two I/O banks. Two other I/O banks are fixed at 3.3 V. The remaining I/O bank is for high voltage analog I/Os that support direct connection to voltages ranging from –12 V to +12 V. These I/Os support current monitoring, temperature monitoring, and metal-oxide semiconductor field-effect transistor (MOSFET) driver outputs.
