CY62146DV30LL-70ZSXIT

Product Overview

The CY62146DV30LL-70ZSXIT from Cypress Semiconductor Corp is an asynchronous SRAM memory IC with a volatile 4Mbit organization of 256K x 16 and a parallel interface. The 256K x 16 organization presents 16 data bits per address word. It provides 70 ns access time and a 70 ns write cycle time, operates from 2.2V to 3.6V, and is specified for ambient temperatures from -40°C to 85°C. The device uses a surface-mount 44-TSOP II package, 0.400 in (10.16 mm) wide, and is part of the MOBL series.

Key Features

• 4Mbit volatile SRAM with 256K address locations and 16 data bits per word
• Asynchronous parallel memory interface
• 70 ns access time and 70 ns write cycle time
• 2.2V to 3.6V supply voltage range
• -40°C to 85°C ambient operating temperature range
• Surface-mount 44-TSOP II package, 0.400 in (10.16 mm) wide

Applications

• Embedded systems requiring volatile working memory for temporary data storage
• Parallel-bus controllers needing 16-bit SRAM expansion for buffered data handling
• Equipment operating across -40°C to 85°C ambient with a 2.2V to 3.6V memory supply

Design & Procurement Notes

When selecting this Cypress Semiconductor Corp device, confirm that the PCB footprint matches the 44-TSOP II package and that the 10.16 mm body width fits adjacent components and board clearance. Verify that the selected memory bus width aligns with the 16-bit organization and that the host timing budget supports 70 ns access and write cycles. Ensure the supply voltage remains within 2.2V to 3.6V. The -40°C to 85°C ambient range should be considered during thermal and mechanical planning, while the volatile format should be reflected in system power design.
