7134SA45JI8

Overview

The Renesas Electronics Corporation 7134SA45JI8 is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 32 kilobits. The device features a parallel interface and an access time of 45 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 68-pin plastic leaded chip carrier package measuring 24.21 by 24.21 millimeters.

Feature Summary

• Supports simultaneous independent access to the same memory location from both ports
• Includes fully asynchronous operation capabilities for flexible system integration
• Integrates on-chip hardware semaphore logic for port arbitration

Applications

• High-speed data buffering in telecommunications equipment
• Real-time processing systems requiring concurrent read/write operations
• Industrial control applications operating in extended temperature environments

Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Verification of availability through authorized distributors is required, as stock may be limited or obsolete. Compliance with RoHS directives is not met for this specific part number. Buyers should confirm final unit condition and authenticity before acquisition due to the discontinued lifecycle stage.

Selection Notes

Engineers selecting this component must account for its discontinuation status when designing new products. The 68-PLCC package requires specific footprint considerations during PCB layout. Verify that the 45-nanosecond access speed meets system timing requirements. Ensure the design accommodates the specified 4.5V to 5.5V power supply range and industrial temperature constraints without additional thermal management.

Part Context

The 7134SA series belongs to Renesas' high-speed dual-port SRAM family, designed for applications demanding concurrent data access. This specific model represents the 32Kb density variant with 45ns performance. The series utilizes true dual-ported memory cells and includes semaphore logic for managing access conflicts between connected processors or controllers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-to-pin replacements may require verification against current Renesas product portfolios or alternative manufacturers offering equivalent dual-port SRAM specifications.
