7134LA35CB

Overview

The Renesas Electronics Corporation 7134LA35CB is a high-speed 4K x 8 Dual-Port Static Random Access Memory (SRAM) designed for systems requiring simultaneous access to the same memory location without on-chip hardware arbitration. This asynchronous component features true dual-ported memory cells and operates with a TTL-compatible single 5V power supply, supporting a voltage range of 4.5V to 5.5V. It offers a maximum access time of 35ns and includes an automatic power-down feature controlled by chip enable signals. The device is housed in a 48-pin CDIP-SB package and supports battery backup operation for data retention.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access from either port.

Applications

• Systems requiring external arbitration or contention handling for shared memory locations.
• Applications intolerant of wait states during memory access operations.
• Industrial equipment utilizing asynchronous parallel SRAM interfaces.

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions. Confirm RoHS compliance details and specific package markings against official manufacturer documentation prior to procurement. Ensure compatibility with existing system voltage levels and interface requirements.

Selection Notes

Select this component for designs necessitating high-speed asynchronous dual-port memory with industrial temperature capabilities. Consider the 48-pin CDIP package constraints and verify that the system can manage potential bus contention when both ports access identical addresses simultaneously.

Part Context

This part belongs to the 7134 series of dual-port SRAMs manufactured by Renesas Electronics. It provides a reliable solution for embedded applications requiring fast, non-blocking memory access across two distinct interfaces within a compact integrated circuit form factor.

Replacement Considerations

Check for direct pin-to-pin replacements within the 7134 family, such as variants with different access speeds or packaging options, ensuring functional equivalence in dual-port arbitration logic.
