Asynchronous SRAMs enable higher system performance

The new devices are suitable for applications in telecommunications, computers, peripherals, and consumer, medical and military domains and are designed to enhance system performance in concert with 32bit dsps, fpgas and processors. The new 128Mbit (CY62192ESL), 64Mbit (CY62182ESL) and 32Mbit (CY62172ESL) MoBL devices feature 32bit I/O configuration with 55ns access time and a voltage range of 1.7 to 5.5V. The SRAMs are available in an RoHS compliant 119 BGA package with a footprint of 14.0 x 22.0 x 2.4 mm and are fabricated using Cypress' 90nm R95 cmos technology. "In applications that require large amount of data transfer between an SRAM and a controller, including image, audio, video and gaming applications, throughput is a major performance factor," said Sunil Thamaran, senior director of the Asynchronous Memory Business Unit at Cypress. "By introducing these new 32bit wide SRAM devices, Cypress demonstrates its strong commitment to address advanced performance requirements in this market space. We have also started development of our next generation of high performance asynchronous memory products in 65nm technology that will further reduce power consumption and add advanced features including ECC." The devices are currently sampling in limited quantities to lead customers and full qualification is in progress.
