7132LA35CB

Overview

The Renesas Electronics Corporation 7132LA35CB is a high-speed, 16-kilobit (2K x 8) CMOS Dual-Port Static Random Access Memory. It features asynchronous parallel interfaces with a maximum access time of 35 nanoseconds. The device operates on a single 4.5V to 5.5V power supply and supports simultaneous independent access to the same memory location by two separate ports. It is housed in a 48-pin Ceramic Dual In-Line Package with Side Brazed contacts.

Feature Summary

• True dual-ported memory architecture enabling simultaneous read/write access from two independent ports without external arbitration logic.
• On-chip port arbitration logic manages conflicts when both ports attempt to access the same memory address simultaneously.
• Battery backup capability allows for data retention at low voltage levels, ensuring non-volatile storage during power interruptions.

Applications

• High-performance computing systems requiring fast data exchange between processors.
• Industrial control applications needing reliable memory buffering.
• Telecommunications equipment utilizing dual-port RAM for signal processing tasks.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm package integrity and pin compatibility before integration. Review official discontinuation notices for final purchase deadlines and last-time buy information. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this component for designs requiring true dual-port functionality with minimal external logic overhead. Consider the ceramic package for enhanced durability in harsh environments. Evaluate thermal management needs as the device operates within standard commercial temperature ranges. Compare against newer generations if lead times are critical for production schedules.

Part Context

This part belongs to the 7132LA series of dual-port SRAMs, designed for stand-alone use or as master devices in wider word configurations. It complements slave devices like the 7142 series to expand memory width. The LA suffix indicates specific electrical characteristics compatible with TTL standards.
