71V2556S100PFGI8

Overview

The 71V2556S100PFGI8 is a 3.3V CMOS synchronous SRAM organized as 128K x 36, providing a total capacity of 4.5 Mbit. It operates with a maximum clock frequency of 100 MHz and features a 5 ns access time. The device utilizes a pipelined architecture to eliminate dead bus cycles during read/write transitions. It supports 2.5V I/O levels while maintaining a 3.3V core voltage supply range of 3.135V to 3.465V. The component is housed in a 100-pin TQFP package with dimensions of 20.0 x 14.0 mm and a 0.65 mm pitch.

Feature Summary

• Eliminates dead bus cycles when turning the bus around between reads and writes or writes and reads
• Supports high-speed data transfer through a pipelined synchronous architecture
• Features 2.5V I/O compatibility for flexible system integration

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing ZBT SRAM technology
• Industrial control applications needing reliable synchronous memory storage

Procurement Notes
