CY62128ELL-45ZXA

Product Overview

The CY62128ELL-45ZXA from Cypress Semiconductor Corp is a volatile SRAM device organized as 128K x 8 bits, providing 1 Mbit of memory. It uses an asynchronous parallel interface and has a 45 ns access time. The device operates from a 4.5 V to 5.5 V supply and over an ambient temperature range of -40°C to 85°C. The package is 32-TSOP I surface mount, corresponding to 32-TFSOP with a 0.724 in (18.40 mm) width.

Key Features

• Volatile SRAM memory format with 1 Mbit capacity.
• 128K x 8 memory organization.
• Asynchronous parallel memory interface.
• 45 ns access time and 45 ns write cycle time.
• 4.5 V to 5.5 V operating supply range.
• -40°C to 85°C operating temperature range.
• 32-TSOP I surface-mount package.

Applications

• Parallel memory expansion in embedded controller systems.
• Temporary data buffering in microcontroller-based designs.
• Volatile memory staging in data acquisition equipment.

Design & Procurement Notes

Design considerations should account for the 5 V supply range, parallel bus timing, and surface-mount footprint. The 45 ns access and write cycle time should be checked against the controller or host interface timing budget. Because the memory is volatile, data remains only while supply voltage is maintained. The 32-TSOP I package and 32-TFSOP width should be verified against PCB land pattern, spacing, and assembly constraints within the -40°C to 85°C ambient range. Use the exact manufacturer part number CY62128ELL-45ZXA when ordering to ensure the package and timing values are matched.
