7025S35J

Memory IC Overview

The Renesas Electronics Corporation 7025S35J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kbit, organized as 8k words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an 84-PLCC package. The component is designed for commercial temperature operation between 0°C and +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array from two separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications, as this specific variant may not meet current environmental directives. Validate package integrity upon receipt to ensure pin compatibility with existing PCB footprints.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure system power supplies remain stable within the 4.5 V to 5.5 V range. Consider the 84-PLCC package dimensions during layout planning. Verify that the 35 ns access speed meets the timing constraints of the target application bus.
