71T75602S166PFG

Overview

The IDT71T75602S166PFG is a synchronous Single Data Rate Zero Bus Turnaround SRAM manufactured by Renesas Electronics. It provides an 18 Mbit storage capacity organized as 512K words by 36 bits. The device operates with a maximum clock frequency of 166 MHz and features a typical access time of 3.5 ns. It utilizes a parallel interface and requires a supply voltage between 2.375 V and 2.625 V. The component is housed in a 100-TQFP (14x14) surface-mount package and supports an industrial operating temperature range from 0°C to 70°C.

Feature Summary

• Supports high-performance system speeds through pipelined outputs and internal synchronization of the output buffer enable.
• Eliminates dead cycles between write and read operations via Zero Bus Turnaround technology.
• Features individual byte write control for precise data management across the 36-bit width.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network infrastructure systems
• Data storage within industrial automation controllers
