7024S55PFI8

Memory IC Overview

The Renesas Electronics Corporation 7024S55PFI8 is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interface operation with an access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 100-TQFP package measuring 14x14 mm. The component is rated for an ambient operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface supporting standard logic levels
• Extended industrial temperature rating for reliable performance in harsh environments

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• FIFO buffer applications in digital signal processing systems
• Cache memory implementation in embedded control systems

Memory IC Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as historical data indicates potential non-compliance for this series. Check for active discontinuation notices or end-of-life notifications prior to finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 64Kb dual-port SRAM with 55ns speed is required in a 100-pin TQFP footprint. Ensure the design accommodates the 4.5V to 5.5V supply requirement and the -40°C to 85°C temperature range. Verify that the parallel interface signals match the system bus requirements.
