CY62128EV30LL-45ZXIT

Product Overview

The Infineon Technologies CY62128EV30LL-45ZXIT is a 1Mbit volatile SRAM device organized as 128K x 8 with a parallel memory interface. It uses a surface-mount 32-TSOP I package with a 32-TFSOP 0.724 inch (18.40 mm) body width. The asynchronous SRAM has a 45 ns access time and a 45 ns write cycle time for word or page operations, and it operates from a 2.2 V to 3.6 V supply over a -40°C to 85°C temperature range.

Key Features

• 1Mbit volatile SRAM with 128K x 8 memory organization
• Parallel memory interface for 8-bit data paths
• 45 ns access time and 45 ns word or page write cycle time
• 2.2 V to 3.6 V supply voltage range
• Surface-mount 32-TSOP I package, 32-TFSOP 0.724 inch (18.40 mm) width
• -40°C to 85°C operating temperature range

Applications

• Embedded controller systems that use local volatile SRAM as a data buffer
• Communications equipment that temporarily holds packet or protocol state information in parallel SRAM
• Instrumentation devices that store sampled values before processing or transfer
• Control or operator interface systems that need local volatile memory for display or configuration data

Design & Procurement Notes

Designers should confirm that the host controller supports an 8-bit parallel SRAM bus and can meet the 45 ns access and write timing requirements. The 2.2 V to 3.6 V supply range must be matched to the system power rail, and layout should account for the surface-mount 32-TSOP I footprint, including the 32-TFSOP 0.724 inch (18.40 mm) body width. Because the device is volatile SRAM, stored data is retained only while supply power is present. The -40°C to 85°C temperature range should be checked against the expected ambient conditions of the final assembly.
