71V546XS133PFG

Overview

The IDT 71V546XS133PFG is a synchronous ZBT SRAM with a 4.5Mb capacity and 128K x 36 organization. It operates at a maximum clock frequency of 133 MHz with a 5 ns access time. The device uses a 100-TQFP (14x20) package and supports a supply voltage range of 3.135V to 3.465V. It functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Synchronous Single Data Rate (SDR) architecture for high-speed parallel data transfer
• Zero Bus Turnaround (ZBT) technology eliminates wait states during read-to-write transitions
• Burst counter pipelined outputs ensure continuous data flow without latency penalties

Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications systems utilizing synchronous memory interfaces
• Industrial control applications needing reliable volatile storage

Procurement Notes

Verify the specific suffix 'XS' against official Renesas documentation, as standard listings often reference 'S' variants. Confirm lead times and availability status directly with authorized distributors, as this component may be subject to end-of-life notices or production changes documented in Product Change Notices.

Selection Notes

Select this part when a 128K x 36 configuration is required with 133 MHz synchronous performance. Ensure the design accommodates the 100-TQFP footprint and 3.3V I/O levels. Compare against the 71V546S133PFG if the 'XS' suffix does not denote a critical functional difference in your specific application context.
