71V65603S133BG

Overview

The 71V65603S133BG is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The device operates with a maximum clock frequency of 133 MHz and provides an access time of 4.2 ns. It utilizes a parallel interface and requires a supply voltage ranging from 3.135 V to 3.465 V. The component is housed in a 119-PBGA package measuring 14x22 mm and supports surface mount installation. It functions within a temperature range of 0°C to +70°C.

Feature Summary

• Supports synchronous Single Data Rate (SDR) operation for high-speed data transfer
• Designed with Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read-write transitions
• Provides pipelined architecture for efficient processing throughput

Applications

• High-performance networking equipment requiring fast memory access
• Industrial control systems utilizing synchronous SRAM interfaces
