CY62147DV30LL-70BVI

Memory IC Overview

The CY62147DV30LL-70BVI is a 2Mbit (256K x 8) CMOS static RAM manufactured by Cypress Semiconductor. It operates at a supply voltage of 3.0V to 3.6V and features a 70ns access time. The device utilizes a 44-pin TSOP II package with a 0.4mm pitch. Key electrical characteristics include low standby current typical of 20µA and active current of 100mA. It supports byte write operations via the /LB and /UB control lines, allowing independent writing to upper and lower bytes.

Memory IC Feature Summary

• Low power consumption with dedicated standby mode capabilities
• High-speed asynchronous operation suitable for demanding applications
• Independent byte write controls for flexible data management

Memory IC Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems needing reliable static memory
• Communication devices utilizing high-speed data buffering

Memory IC Procurement Notes

Verify the specific suffix 'BVI' against official Cypress documentation to confirm package type and temperature range. Ensure compatibility with 3.3V logic levels in your system design. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or end-of-life status before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 256K x 8 configuration is required with 3.3V operation. Consider the 70ns speed grade if system timing allows. Evaluate the TSOP II package dimensions against PCB layout constraints. Compare power specifications against alternatives if ultra-low standby current is critical for the application.

Memory IC Part Context

This part belongs to the CY621xx series of SRAMs, designed for general-purpose memory storage. The series offers various speed grades and package options. The CY62147 variant specifically provides 2Mbit capacity. Cypress Semiconductor integrated this line into its broader memory portfolio before being acquired by Infineon Technologies.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as other speed grades like the 80ns version. Verify that substitute parts maintain the 3.3V operating voltage and similar power characteristics. Consult official substitution guides for confirmed equivalents.
