7134SA70J

Overview

The Renesas Electronics Corporation 7134SA70J is a dual-port static random access memory (SRAM) device organized as 4K words by 8 bits, providing a total storage capacity of 32 kbit. It features asynchronous parallel interface operation with a maximum access time of 70 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 52-PLCC package. It is designed for commercial temperature environments ranging from 0°C to +70°C.

Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on separate ports
Asynchronous parallel interface supporting standard logic levels
Single power supply operation compatible with 5V systems

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications, as this specific part number does not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC footprint.

Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access without arbitration overhead. Ensure system design accommodates the 52-PLCC surface mount package dimensions. Verify that the 70 ns access speed meets timing constraints for the target application bus frequency.

Part Context

This device belongs to the 7134SA series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a legacy solution for applications requiring independent port access. The part is distinct from single-port variants and offers higher integration density compared to earlier generations in the same family.
