71V3559S80BG

Memory IC Overview

The 71V3559S80BG is a 4.5Mb synchronous single data rate (SDR) zero-burst SRAM manufactured by Renesas Electronics Corporation. It features a parallel interface with an access time of 8 ns and operates within a supply voltage range of 3.135V to 3.465V. The device is organized as 256K x 18 bits and utilizes a 119-pin PBGA package measuring 14x22 mm. Designed for surface mount installation, it supports an operating temperature range from 0°C to 70°C.

Memory IC Feature Summary

• Supports synchronous SDR zero-burst memory operations via a parallel interface.
• Provides fast 8 ns access time for high-speed data retrieval.
• Operates on a standard 3.3V core power supply with defined voltage limits.

Memory IC Applications

• High-performance embedded systems requiring fast random access memory
• Network infrastructure equipment utilizing parallel bus architectures
