CY62128DV30LL-55ZAXI

Product Overview

The CY62128DV30LL-55ZAXI from Cypress Semiconductor Corp is a 1Mbit asynchronous SRAM memory IC in the MOBL series. It provides a 128K x 8 volatile memory organization with a parallel interface, for systems requiring parallel SRAM data storage. The device operates from a 2.2V to 3.6V supply, has a 55 ns access time and 55 ns write cycle time, and is specified for an operating temperature range of -40°C to 85°C. It is supplied in a 32-TSOP surface-mount package.

Key Features

• Memory capacity is 1Mbit, organized as 128K x 8.
• The device uses an asynchronous parallel memory interface.
• Access time and write cycle time are both specified at 55 ns.
• Supply voltage range is 2.2V to 3.6V.
• Operating temperature range is -40°C to 85°C ambient.
• Package is 32-TSOP, with surface-mount mounting.
• It is a volatile SRAM memory device from the MOBL series.

Applications

• Volatile working memory for microcontroller or processor systems that use a parallel memory bus.
• Data buffering where temporary read and write operations are required.
• Memory expansion in compact surface-mount assemblies using the 32-TSOP package.
• Storage of transient state or configuration data in systems operating from 2.2V to 3.6V.

Design & Procurement Notes

Design considerations should focus on matching the 128K x 8 parallel interface to the host bus, maintaining the 2.2V to 3.6V supply within the specified range, and allowing for the 55 ns timing when selecting read and write cycles. Because the memory type is volatile, data retention behavior should be considered in system design. The 32-TSOP surface-mount package supports compact board layouts, and the -40°C to 85°C ambient range defines the specified operating conditions. The 1Mbit capacity and 128K x 8 organization also define the available addressable space for firmware and hardware design.
