7005S45J

Overview

The Renesas Electronics 7005S45J is a 64Kbit (8K x 8) dual-port static random-access memory (SRAM) IC. It features asynchronous parallel interface with a maximum access time of 45 ns. The device operates on a single 5V power supply, with voltage range from 4.5V to 5.5V. Maximum supply current is 210 mA. It supports surface mount installation in a 68-PLCC package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations
Asynchronous parallel interface for flexible system integration
Integrated semaphore, interrupt, and busy signals for master/slave coordination

Applications

High-speed data buffering in communication systems
Cache memory in embedded processors
FIFO buffers in industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Validate pin compatibility with existing PCB footprints. Review datasheet for specific electrical characteristics matching system requirements.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare access times against system timing constraints. Evaluate package size limitations against available board space. Consider power consumption limits relative to thermal management capabilities. Assess long-term availability risks associated with discontinued product lines.

Part Context

Part of the 7005 series dual-port SRAM family. Shares architectural similarities with 7005S35J and 7005L45J variants. Differentiated primarily by access speed and package options within the same manufacturer lineup. Designed for applications requiring high-bandwidth memory sharing between two independent bus masters.
