7133SA35J8

Overview

The Renesas Electronics Corporation 7133SA35J8 is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 32 kilobits, organized as 2K words by 16 bits. It features asynchronous parallel interface operation with a maximum access time and write cycle time of 35 nanoseconds. The device operates on a single 4.5V to 5.5V power supply and is housed in a 68-lead Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm x 24.21mm. It supports surface mount installation and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports
• Asynchronous operation allowing flexible timing control for both read and write cycles
• CMOS technology providing low power consumption characteristics

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific suffix indicates non-compliance with current environmental directives. Validate package integrity upon receipt, ensuring no pin damage or contamination. Check datasheet revisions for any packaging or labeling changes documented in Product Change Notices. Ensure design-in compatibility with existing board layouts before final procurement decisions.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave operations. Compare against single-port alternatives if only one access point is necessary to reduce cost. Consider the 68-PLCC package constraints for PCB space availability. Evaluate thermal management needs given the operating temperature range. Verify voltage tolerance matches the system power supply rails precisely.

Part Context

This part belongs to the 7133SA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7133SA35J but differs in packaging and moisture sensitivity levels. The series is designed for applications requiring high-speed, independent port access without bus contention.
