70V05S20J8

Memory IC Overview

The Renesas Electronics Corporation 70V05S20J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kbit, organized as 8K words by 8 bits. The device operates with an access time of 20 ns and supports parallel interface communication. It functions within a supply voltage range of 3.0 V to 3.6 V. The component is housed in a 68-PLCC package with dimensions of 24.21x24.21 mm. It is designed for surface mount installation and operates at temperatures 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 equipment
• Cache memory implementation in embedded systems
• 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 as the part may not meet current environmental standards. Validate package integrity upon receipt to ensure suitability for automated surface-mount assembly processes.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure system power supplies align with the 3.0 V to 3.6 V operating range. Verify that the 68-PLCC footprint matches the printed circuit board design constraints.

Memory IC Part Context

This part belongs to the 70V05S series of asynchronous dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but differs in speed grade and voltage specifications.
