7134SA35J

Overview

The Renesas Electronics Corporation 7134SA35J is a high-speed, 32K-bit (4K x 8) Dual-Port Static Random Access Memory (SRAM). It features fully asynchronous operation from either port and supports simultaneous access to the same memory location. The device operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. It has an access time of 35ns and is housed in a 48-pin LCC package.

Feature Summary

• True dual-ported memory cells allowing simultaneous independent access from two ports.
• Fully asynchronous operation eliminating the need for external clock synchronization.
• Automatic power-down feature controlled by chip enable signals for low standby power.

Applications

• Systems requiring hardware-independent dual-port data sharing.
• Real-time processing applications needing concurrent read/write operations.
• Industrial equipment utilizing high-speed volatile memory buffers.

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity handling prior to installation. Review official discontinuation notices for final purchase timing constraints. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Selection Notes

Select this component when true dual-port functionality is required without internal arbitration logic. Suitable for designs where external contention management is preferred over built-in hardware arbitration. Verify that the 48-pin LCC package fits the target PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 7134 series of high-speed dual-port SRAMs designed for systems tolerant of external arbitration. It serves as a bridge between different processing domains requiring fast, conflict-managed memory access. The series supports various package options including DIP, LCC, and PLCC formats.
