7134LA35J

Overview

The Renesas Electronics Corporation 7134LA35J 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 and write cycle time of 35 nanoseconds. It operates on a single 5V power supply within the range of 4.5V to 5.5V. The component is housed in a 48-pin Leadless Ceramic Chip Carrier (LCC) package designed for surface mount technology.

Feature Summary

• Supports simultaneous independent access to the same memory location from both ports without hardware arbitration
• Enables automatic low-power standby mode through chip enable control signals
• Compatible with battery backup operations for data retention at reduced voltage levels

Applications

• Systems requiring external arbitration for concurrent memory access
• Network communication equipment utilizing dual-port buffering
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against design specifications. Ensure supply chain sources provide traceability documentation. Check for available last-time-buy options or approved alternates.

Selection Notes

Evaluate thermal performance for industrial temperature ranges up to 125°C. Assess power consumption limits relative to system constraints. Verify compatibility with existing parallel bus architectures. Consider moisture sensitivity levels during assembly processes. Review datasheet specifications for signal integrity requirements.

Part Context

This component belongs to the 7134LA series of dual-port SRAMs manufactured by Renesas Electronics. It succeeds earlier IDT designs under the same functional specifications. The LA suffix indicates availability in industrial temperature grades. The series supports various package formats including LCC and DIP configurations.

Replacement Considerations

Consult official manufacturer documentation for qualified substitute part numbers. Verify pinout compatibility before implementing any alternative components.
