7007S55JI

Memory IC Overview

The Renesas Electronics Corporation 7007S55JI is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a total storage capacity of 256 kbit, organized as 32K words by 8 bits. The device features a parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-PLCC package. The component is designed for independent read/write operations on both ports.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations on two separate ports
• Asynchronous operation without requiring a system clock signal
• High-speed data access capabilities for efficient processing

Memory IC Applications

• Stand-alone dual-port memory systems
• Master/Slave dual-port RAM configurations

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation, as variations may exist. Confirm end-of-life status and availability through authorized channels. Ensure compatibility with existing PCB footprints and voltage levels. Check for moisture sensitivity handling requirements during assembly. Validate that the selected variant meets all environmental and electrical specifications for the target application.

Memory IC Selection Notes

Select this component when independent concurrent access to memory is required. Consider the 55 ns access speed for timing constraints. Evaluate the 68-PLCC package size for board space limitations. Ensure the operating temperature range aligns with the deployment environment. Compare power consumption metrics if battery life is a critical factor.
