7134SA70J8

Overview

The Renesas Electronics Corporation 7134SA70J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits organized as 4K words by 8 bits. The device features a parallel interface with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin PLCC package. The component is designed for systems where on-chip hardware port arbitration is not required.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or controllers without internal arbitration logic.

Applications

• Systems requiring independent processor access to shared memory resources.
• High-speed data buffering applications in embedded architectures.
• Parallel interface memory expansion for legacy or specialized microcontroller systems.

Procurement Notes

Verify the specific suffix J8 against official datasheets to confirm package type and temperature range. Confirm RoHS compliance status as older variants may differ. Check current lifecycle status as this model may be discontinued. Ensure pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when dual-port functionality is necessary for concurrent read/write operations. Compare access times and power consumption against single-port alternatives if arbitration hardware is available. Verify that the 52-PLCC package fits the target assembly constraints and thermal requirements.

Part Context

This part belongs to the 7134SA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7134SA70J but differs in packaging and specific electrical characteristics defined by the suffix. The series targets applications needing fast, non-arbitrated memory sharing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer obsolescence notices for potential end-of-life replacements.
