SAN JOSE -- Cypress Semiconductor Corp. today announced a dual-ported memory that serves as a PCI bus controller with integrated glue logic and interface for a variety of embedded processors, including those from Intel, Motorola and Texas Instruments. Cypress said the device can be connected directly to 8-, 16-, and 32-bit processors without glue logic.
The CY7C09449PV device provides 4-Kbits-by-32 of dual-port memory for data transfer from processors to PCI buses in two steps instead of the normal three-step approach. This will end up reducing system bottlenecks and time delays in moving data from embedded processors to the PCI bus, said Cypress.
The single-chip PCI-dual port solution leverages Cypress' know-how in multiport memories "to meet the needs of an exceptionally broad array of networking, storage, and high-end computation customers," said Jim Dillon, product marketing manager for multi-port memories. "We are targeting the critical mass of the market with 128-K of dual-ported memory and the 33/32 PCI standard."
He said Cypress intends to "seed the market for a higher-density, higher-speed device roadmap" in multiport memory applications for PCI.
The new chip integrates PCI bridge function, memory and glue logic for reduced system costs and board-space requirements. The dual-port-PCI bus controller also provides a configurable, 50-MHz local interface that can be configured for most processors in embedded applications, said Cypress.
The PCI-dual port chip is available now in sample quantities. Production is slated to start in the third quarter. The controller is packaged in a 160-pin TQFP package and priced at $18.30 each in quantities of 10,000.
