7133SA70J

Overview

The Renesas Electronics Corporation 7133SA70J is a 32Kb (2K x 16) asynchronous dual-port static random-access memory (SRAM). It features a parallel interface with a maximum access time of 70 ns. The device operates on a single 5V power supply ranging from 4.5V to 5.5V. It is housed in a 68-lead Plastic Leadless Chip Carrier (PLCC) package measuring 24.21x24.21 mm. The component supports surface mount installation and functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access by two masters
• Supports standard parallel bus interface for direct microprocessor connection
• Utilizes CMOS technology for low power consumption during operation

Applications

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

Procurement Notes

Verify the specific suffix J against official documentation to confirm package dimensions and lead finish, as variations exist within the family. Confirm RoHS compliance status, as this specific part number may not meet current environmental directives. Check manufacturer announcements for end-of-life notices or recommended replacement parts before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access without arbitration logic. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Verify that the 68-PLCC footprint matches the printed circuit board design constraints. Consider thermal management requirements for the specified commercial/industrial temperature range.

Part Context

This device belongs to the 7133SA series of high-speed dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to suit different performance and form factor requirements. The 70 ns speed grade provides a balance between access latency and power efficiency for general-purpose memory applications.
