7133SA25J8

Memory IC Overview

The 7133SA25J8 is a 32Kbit (2K x 16) dual-port static random-access memory manufactured by Renesas Electronics. It features asynchronous parallel interface with a 25 ns access time and operates on a 4.5V to 5.5V supply voltage. The component is housed in a 68-PLCC surface-mount package and supports commercial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors
• Asynchronous operation requiring no external clock signals
• CMOS technology ensuring low power consumption during standby

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

This component is officially discontinued by the manufacturer. Verify end-of-life status and availability through authorized distributors or secondary markets before integration into new designs. Ensure compliance with RoHS non-compliance declarations and moisture sensitivity level requirements during handling.

Memory IC Selection Notes

Select this part only if legacy compatibility with 68-pin PLCC footprints and 25 ns timing is required. Evaluate alternative modern SRAMs with smaller packages and lower voltage requirements for new projects. Confirm that the dual-port capability aligns with specific multi-processor communication needs.

Memory IC Part Context

Part of the 7133SA series, this device belongs to Renesas' portfolio of high-performance dual-port memories. It shares architectural similarities with other members like the 7133LA series but differs in operating temperature range and packaging options. The series targets applications requiring fast, independent read/write cycles.

Memory IC Replacement Considerations

IDT7133SA25J8 is an equivalent part number under the Integrated Device Technology brand, now part of Renesas.
