CY62128EV30LL-45ZAXI

Product Overview

The Cypress Semiconductor Corp CY62128EV30LL-45ZAXI is an asynchronous volatile SRAM memory IC organized as 128K x 8 for a total memory size of 1 Mbit. It uses a parallel memory interface and has 45 ns access time and 45 ns write cycle time. The device operates from a 2.2 V to 3.6 V supply and is rated for an ambient temperature range of -40°C to 85°C. The package is a 32-TFSOP surface-mount case, also called 32-sTSOP.

Key Features

• 1 Mbit volatile SRAM memory
• 128K x 8 memory organization
• Asynchronous parallel memory interface
• 45 ns access time and 45 ns write cycle time
• 2.2 V to 3.6 V supply voltage range
• -40°C to 85°C operating temperature range
• 32-TFSOP surface-mount package, also called 32-sTSOP

Applications

• Embedded systems that require volatile parallel memory for temporary data storage
• Microcontroller-based designs that use asynchronous SRAM for data buffering
• Controller boards that need byte-wide memory expansion within the specified supply and temperature limits

Design & Procurement Notes

Designers should verify that the system supply remains within 2.2 V to 3.6 V and that the board layout supports a 32-TFSOP surface-mount footprint. Because the device uses a parallel interface, the controller or processor must provide the necessary address, data, and control signals for asynchronous SRAM operation. The 45 ns access and write cycle times should be checked against the host timing budget. The -40°C to 85°C ambient rating should be compared with the expected operating environment. The 128K x 8 organization should match the required address space and byte-wide data width. Confirm package dimensions and land pattern for 32-sTSOP before layout sign-off.
