CY62128DV30LL-55SXIT

Product Overview

The CY62128DV30LL-55SXIT from Cypress Semiconductor Corp is an asynchronous SRAM memory integrated circuit offering 1Mbit of volatile storage in a 128K x 8 organization. It uses a parallel memory interface and is supplied in a surface-mount 32-SOIC package. The device operates from a 2.2 V to 3.6 V supply and is specified for an ambient temperature range of -40°C to 85°C. Its 55 ns access time and 55 ns write cycle time define its timing behavior.

Key Features

• 55 ns write cycle time for word and page operations
• 2.2 V to 3.6 V supply voltage range
• -40°C to 85°C ambient operating temperature range
• Surface-mount 32-SOIC package with 0.445 inch, 11.30 mm width

Applications

• Embedded systems requiring parallel SRAM expansion
• Microcontroller and processor-based designs needing volatile temporary data storage
• Data acquisition and instrumentation systems using asynchronous SRAM for buffered data capture

Design & Procurement Notes

For design planning, confirm that the host controller can address a 128K x 8 parallel SRAM and meet the 55 ns access and write cycle timing. The 2.2 V to 3.6 V supply range should be checked against the system power rail, and the -40°C to 85°C ambient range should be verified against the enclosure thermal environment. The surface-mount 32-SOIC package requires a compatible PCB footprint and surface-mount assembly process. Because the memory is volatile, retain supply power to preserve stored data. Specify the exact part number CY62128DV30LL-55SXIT to retain the 32-SOIC package and 55 ns timing.
