7133LA45G

Overview

The Renesas Electronics Corporation 7133LA45G is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features a parallel interface with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole installation in a 68-pin PGA package. The component is designed for industrial temperature ranges.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• CMOS technology providing high-speed data transfer capabilities with low power consumption characteristics.

Applications

• Embedded system memory modules requiring independent data access paths.
• Industrial control systems utilizing parallel interface communication protocols.
• Telecommunications equipment needing reliable volatile storage for temporary data buffering.
