  PCI 3.3V Bus Master/Target Device 32-bit

Product Status: Production Release

General Description

AMCC’s S5335 MatchMaker is a powerful and flexible PCI controller supporting several levels of interface sophistication. At the lowest level it can serve simply as a bus target with modest transfer requirements. For high performance applications, the S5335 can become the bus master and can attain the peak transfer capabilities of 132 Mbyte/sec with a 32 bit bus. The MatchMaker is an off-the-shelf, low cost standard product that allows a faster time to market by allowing the designer to focus on the actual application and not on debugging the PCI interface.


The S5335 can be used to implement a wide range of high speed applications. With its microprocessor independent add-on interface, the MatchMaker can be used for networking, video, communications or data acquisition applications. The MatchMaker allows special direct data accessing between the PCI bus and the user application through implementation of four definable Pass-Thru data channels. Each data channels is implemented by defining a Host memory segment size and 8/16/32-bit bus user width. FIFO DMA transfers are supported using Address and Transfer count registers. 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 us of an external non-volatile memory to perform any pre-boot initialization requirements and to provide custom expansion BIOS or POST code capability.

The block diagram in the figure below shows the major functional elements within the S5335. The S5335 provides three physical bus interfaces: the PCI Local Bus, the user local bus referred to as the Add-on Local bus and the optional serial and byte-wide non volatile memory buses. Data movement between buses can take place mailbox registers to the FIFO data channel, or a user can define and enable one or more of the Pass-Thru data channels. The S5335 MatchMaker performs Bus Master or DMA data transfers through the FIFO data Channel under either Host or Add-on software control or Add-on hardware control using dedicated signal pins.
