CY62137VNLL-70ZXET

Product Overview

The Cypress Semiconductor Corp CY62137VNLL-70ZXET is an asynchronous SRAM memory IC with a 2 Mbit capacity and a 128K x 16 organization. It uses a parallel memory interface and is packaged in a 44-TSOP II surface-mount package with a 0.400 in, 10.16 mm width. The device operates from a 2.7 V to 3.6 V supply and supports an ambient temperature range of -40°C to 125°C. The access time is 70 ns, and the write cycle time for word and page operations is also 70 ns. The memory type is volatile, so data retention depends on continued supply voltage.

Key Features

• 2 Mbit asynchronous SRAM memory capacity
• 128K x 16 memory organization for parallel data paths
• Parallel memory interface with 70 ns access time
• 70 ns write cycle time for word and page operations
• 2.7 V to 3.6 V supply voltage range
• -40°C to 125°C operating temperature range
• 44-TSOP II surface-mount package with 0.400 in, 10.16 mm width

Applications

• Embedded systems requiring a parallel volatile memory array for temporary data storage
• Controllers and processors that interface to a 128K x 16 asynchronous SRAM
• Surface-mount equipment operating from a 2.7 V to 3.6 V supply over a -40°C to 125°C ambient range

Design & Procurement Notes

When selecting this device, confirm that the system can provide a 2.7 V to 3.6 V supply and that the board layout supports the 44-TSOP II surface-mount package. The 128K x 16 organization and parallel interface require address, data, and control routing consistent with an asynchronous SRAM. Because the memory is volatile, designs must maintain supply voltage during operation and account for data loss when power is removed. The 70 ns access and write timing should be checked against the controller or bus cycle used in the system. The -40°C to 125°C temperature range should be evaluated with the actual board thermal environment, including nearby heat sources and enclosure conditions.
