CY62126DV30LL-55ZXIT

Product Overview

The CY62126DV30LL-55ZXIT from Cypress Semiconductor Corp is an asynchronous SRAM memory IC with volatile 1Mbit storage arranged as 64K x 16 and accessed through a parallel interface. It uses a surface-mount 44-TSOP II package with a 10.16mm body width. The device operates from a 2.2V ~ 3.6V supply and is specified for an ambient temperature range of -40°C ~ 85°C (TA). Its access time and write cycle time are 55 ns, supporting parallel memory attachment in embedded designs that require SRAM.

Key Features

• Asynchronous SRAM memory IC with volatile storage and a 1Mbit capacity.
• Memory organization is 64K x 16, with a parallel interface.
• Access time is 55 ns; write cycle time - word, page is 55 ns.
• Supply voltage range is 2.2V ~ 3.6V.
• Operating temperature range is -40°C ~ 85°C (TA).
• Surface-mount 44-TSOP II package with 10.16mm body width.

Applications

• Embedded controller systems that require parallel SRAM for local data storage.
• Data-acquisition front ends that buffer temporary values before host transfer.
• Test and measurement equipment that uses random-access memory for temporary records.
• Communications devices that store short-lived configuration or packet data in SRAM.

Design & Procurement Notes

Designers should confirm that the host controller supports a 64K x 16 parallel SRAM timing profile and can meet the 55 ns access and write cycle requirements at the 2.2V ~ 3.6V supply. The surface-mount 44-TSOP II footprint should be checked against board layout and thermal considerations across the -40°C ~ 85°C (TA) range. Because the memory type is volatile, designs should not assume data retention after power removal.
