- Wider SRAMs Enable Higher System Performance When Interfacing with DSPs, FPGAs or Microcontrollers/Microprocessors of Identical Bus Width

Adding to its high-performance SRAM portfolio - which already include synchronous, asynchronous and micropower devices spanning 4-Kbit to 128-Mbit densities - Cypress Semiconductor has launched three new Asynchronous SRAMs featuring 32-bit bus widths. The new MoBL® (More Battery Life) SRAMs target applications in telecommunications, computers, peripherals, and consumer, medical and military domains where they will enhance system performance in concert with 32-bit DSPs, FPGAs and processors.

The new 128-Mbit (CY62192ESL), 64-Mbit (CY62182ESL) and 32-Mbit (CY62172ESL) MoBL devices offer 32-bit I/O configuration with 55-ns access time (TAA) and a wide voltage range of 1.7V to 5.5V. According to Ercument Yagmur, general manager of Cypress’ sales representative Ismosys Turkey, throughput is a major performance factor in applications that require a large amount of data transfer between an SRAM and a controller, including image, audio, video and gaming applications: "These new 32-bit wide SRAM devices demonstrate Cypress’ continuing commitment to meeting advanced performance requirements in these key application areas”, Yagmur said. “The company’s next generation of high-performance asynchronous memory products in 65-nm technology will further reduce power consumption and add advanced features including ECC."

The CY62192ESL 128-Mbit, CY62182ESL 64-Mbit and CY62172ESL 32-Mbit Low-Power Asynchronous SRAMs are available in a RoHS-compliant 119-BGA package with a footprint of 14.0 x 22.0 x 2.4 mm. Fabricated using Cypress's high-performance, 90-nanometer R95™ CMOS technology the devices are currently sampling to lead customers, and full qualification of the devices is in progress.
