CY62128ELL-45ZXIT

Product Overview

The CY62128ELL-45ZXIT from Infineon Technologies is a 1Mbit asynchronous SRAM device organized as 128K x 8 with a parallel memory interface. It operates from a 4.5V to 5.5V supply and provides 45 ns access time and 45 ns write cycle time. The device uses a surface-mount 32-TSOP I package with a 32-TFSOP case footprint, 0.724 in (18.40 mm) width, and is specified for operation over a -40°C to 85°C ambient temperature range.

Key Features

• 1Mbit volatile SRAM memory array
• 128K x 8 organization for 8-bit parallel data access
• Asynchronous SRAM technology with 45 ns access time
• 45 ns write cycle time for word or page operations
• 4.5V to 5.5V supply voltage range
• Surface-mount 32-TSOP I package, 32-TFSOP case, 0.724 in (18.40 mm) width
• -40°C to 85°C (TA) operating temperature range

Applications

• Embedded controllers requiring a volatile parallel memory bank for temporary data storage
• Microprocessor-based systems using an 8-bit parallel bus for memory expansion
• Instrumentation and data acquisition equipment that needs short-latency buffering of sampled values
• Communications equipment using parallel SRAM for packet or message buffering

Design & Procurement Notes

When selecting this device, confirm that the host controller supports an asynchronous parallel SRAM interface and that the system power supply remains within 4.5V to 5.5V. The 128K x 8 organization and 45 ns timing should be checked against the required read and write cycles, especially in designs with tight access margins. Layout should account for the 32-TSOP I surface-mount footprint and the parallel signal routing. The -40°C to 85°C (TA) range should be considered relative to the final board thermal environment. Specify the exact part number to match the 32-TSOP I package and 45 ns timing.
