70V05L55J

Memory IC Overview

The Renesas Electronics Corporation 70V05L55J is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device operates asynchronously with parallel interfaces for both ports. It features a maximum access time of 55 nanoseconds and requires a supply voltage ranging from 4.5 volts to 5.5 volts. The component supports an operating temperature range from 0°C to 70°C and is housed in a 68-pin Plastic Leadless Chip Carrier package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring a system clock signal
• Parallel interface supporting standard data bus connections

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific manufacturer source document for the 70V05L55J part number before procurement. Confirm that the 4.5V to 5.5V supply voltage requirement aligns with the target system design. Ensure the 68-PLCC package dimensions are compatible with the printed circuit board layout. Check for RoHS compliance status and moisture sensitivity level requirements relevant to the assembly process.

Memory IC Selection Notes

Select this component when a system requires independent read/write access to shared data via two separate ports. The 55 ns access speed suits moderate-speed asynchronous applications. Verify that the 5V logic levels match the interfacing microcontroller or processor signals. Consider the 68-PLCC package availability if surface-mount assembly is required.
