71V546S133PFGI8

Overview

The 71V546S133PFGI8 is a synchronous single data rate static random access memory manufactured by Renesas Electronics Corporation. It features a parallel interface with a storage capacity of 4.5 Mbit, organized as 128K x 36. The device operates at a clock frequency of 133 MHz with an access time of 4.2 ns. It requires a supply voltage between 3.135 V and 3.465 V and functions within a temperature range of 0°C to 70°C. The component is housed in a 100-TQFP (14x14) surface-mount package.

Feature Summary

• Zero Bus Turnaround technology eliminates dead cycles between read and write operations
• Fully pipelined architecture with positive clock-edge triggered registers for address and control signals
• Supports four-word burst capabilities in either interleaved or linear modes
• Includes individual byte write control pins for precise data masking

Applications

• High-speed digital signal processing systems
