71V3577S75BGG

Overview

The 71V3577S75BGG is a 4 Mbit Synchronous Single Data Rate Static Random Access Memory organized as 128K x 36. It operates with a 3.3V core supply and supports 3.3V I/O levels. The device features a maximum clock frequency of 117 MHz and an access time of 7.5 ns. It utilizes a parallel interface and is housed in a 119-pin PBGA package measuring 14x22 mm. The component functions within a temperature range of 0°C to +70°C.

Feature Summary

• Supports flow-through output architecture for continuous data availability
• Includes self-timed write cycle with global write control and byte write enable capabilities
• Features LBO input for selecting between interleaved or linear burst modes
• Integrates power-down functionality controlled by the ZZ input pin

Applications

• High-performance embedded memory systems requiring synchronous interfaces
• Network infrastructure equipment utilizing 3.3V logic standards
