7007S25J

Memory IC Overview

The Renesas Electronics Corporation 7007S25J is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 256 kilobits, organized as 32K words by 8 bits. The device features parallel interface access with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-PLCC package measuring 29.31x29.31 mm. The component functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations from two separate ports for high-throughput data handling.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processors
• Data storage in industrial control networks

Memory IC Procurement Notes

Verify the specific manufacturer source, as IDT was acquired by Renesas. Confirm RoHS compliance status, as some variants are marked non-compliant. Check current lifecycle status, as many 7007 series parts are discontinued or have limited availability. Ensure the 84-PLCC package matches the target PCB footprint requirements.

Memory IC Selection Notes

Select this component when dual-port architecture is required for concurrent host and peripheral access. Compare against other 7007 series variants based on access speed and organization. Verify that the 84-pin PLCC package fits the design constraints. Consider alternative packages like TQFP if pin count or form factor differs.

Memory IC Part Context

The 7007S25J belongs to the Renesas/IDT 7007 family of high-speed dual-port SRAMs. This family offers various capacities and speeds, typically ranging from 16Kx8 to 64Kx8 organizations. These devices are designed for applications requiring fast, independent access from multiple masters without bus contention.

Memory IC Replacement Considerations

Check for direct substitutes such as IDT7007S25J or Renesas equivalents with identical pinouts and electrical characteristics. Verify compatibility with existing system timing requirements before substitution.
