7024S55PFI

Memory IC Overview

The Renesas Electronics Corporation 7024S55PFI is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64Kb, organized as 4K words by 16 bits. The device features parallel interface access with a maximum access time and write cycle time of 55 ns. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 100-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm. It supports surface mount installation and functions across an industrial temperature range from -40°C to +85°C ambient.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to memory locations from two separate ports.
• Asynchronous operation allowing flexible timing control for both read and write cycles without clock synchronization.
• Parallel data interface supporting standard 16-bit word width for direct system bus connectivity.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Network switching systems utilizing dual-port capabilities for packet processing and traffic management.
• Industrial automation controllers needing reliable volatile storage for real-time operational data.

Memory IC Procurement Notes

Verify the specific package variant and suffix codes against official Renesas documentation to ensure compatibility with existing board layouts. Confirm that the 55 ns speed grade matches system timing requirements. Check for end-of-life status or discontinuation notices prior to finalizing procurement plans. Ensure environmental compliance checks align with project specifications, noting RoHS status variations.

Memory IC Selection Notes

Select this component when a 64Kb dual-port SRAM solution is required for applications demanding concurrent port access. The 55 ns speed offers a balance between performance and power consumption for general-purpose industrial use. Consider the 100-TQFP package constraints regarding PCB space and thermal dissipation. Evaluate alternative speed grades if faster access times are necessary for higher throughput demands.
