Acal Semiconductors announces the new AMCC S5335 MatchMaker PCI controller. This powerful and flexible 3.3V device can serve as an easily configured bus target, enabling data transfer at modest rates. For demanding applications, the S5335 can become the bus master, enabling data transfer at rates of up to 132 Mbyte/sec with a 32 bit bus.

The S5335 MatchMaker has a microprocessor independent add-on interface, allowing the designer to choose whatever processor best suits the needs of the application. This flexibility makes the S5335 ideal for systems ranging from digital video and multimedia communications to high speed networking and data encryption/decryption, as well as providing PCI connectivity for numerous other applications.

The S5335 is a PCI 2.1 compliant Master/Slave device. The 3.3V I/Os are 5V tolerant, allowing the device to be used with modern motherboards that require 3.3V PCI operation as well as legacy systems, making the device an ideal solution for designers looking to transition to 3.3V PCI systems.

The S5335 MatchMaker also offers a range of advanced features, including four definable Pass-Thru data channels that allow direct data accessing between the PCI bus and the user application. Each data channel supports FIFO DMA transfers, and allows a user-defined Host memory segment size and selectable 8, 16 or 32-bit bus width. Four 32-bit Mail Box registers coupled with a status register and extensive interrupt capabilities provide flexible user command or message transfers between the two buses. In addition, the S5335 also allows use of an external non-volatile memory to perform any pre-boot initialization requirements and to provide custom expansion BIOS or POST code capability.

The S5335 MatchMaker extends the existing range of 3.3V and 5V AMCC PCI controllers available from Acal Semiconductors. It is supplied in a 176 Pin LQFP and is available in an environmental friendly Lead-free (RoHS) package option. A developersĀ“ kit, the S5335DK, is also available, offering schematics, bill of materials, PCB design, and CPLD code for a hardware reference design, as well as diagnostic and development utility software. The popularity of the company’s earlier controllers means that device drivers are available from several third party software developers, further reducing time to market.
