CY62136CV30LL-70BVI

Product Overview

The CY62136CV30LL-70BVI from Cypress Semiconductor Corp is an asynchronous static random access memory device with a 2Mbit capacity organized as 128K x 16. It uses a parallel memory interface and is supplied in a 48-VFBGA surface-mount package. The device operates from a 2.7V to 3.3V supply and is specified for a temperature range of -40°C to 85°C. Its 70 ns access time and 70 ns write cycle time support parallel read and write operations in systems that use a direct memory interface without a synchronous clock.

Key Features

• 2Mbit SRAM capacity organized as 128K x 16, using a parallel memory interface.
• Asynchronous SRAM operation with 70 ns access time and 70 ns write cycle time.
• 2.7V to 3.3V supply voltage range for parallel memory interface designs.
• Operating temperature range of -40°C to 85°C.
• 48-VFBGA (6x8) surface-mount package.

Applications

• Embedded controllers that use a parallel SRAM interface for stack, buffers, or temporary variables.
• Communications or networking hardware that uses a parallel SRAM interface for packet buffering.
• Instrumentation or test equipment that requires random access to measurement data before processing.

Design & Procurement Notes

Design review should confirm that the host controller can support a 16-bit parallel SRAM interface and meet 70 ns access and write timing. The 2.7V to 3.3V supply range and -40°C to 85°C operating range should be checked against the system power and ambient conditions. Because the memory is volatile, data is retained only while powered, so power sequencing and any retention strategy must be evaluated. The 48-VFBGA (6x8) package requires a compatible surface-mount PCB footprint and assembly process.
