IDT71V2546S150PF8

Memory IC Overview

The IDT71V2546S150PF8 is a 3.3V synchronous ZBT SRAM with a 4.5Mb capacity organized as 128K x 36. It operates at a clock frequency of 150 MHz with a 3.8 ns access time. The device uses a 100-pin TQFP package and requires a 3.3V core supply and 2.5V I/O supply.

Memory IC Feature Summary

• Zero Bus Turnaround technology eliminates dead cycles between read and write operations
• Fully pipelined architecture with positive clock-edge triggered registers
• Internal burst counter supports four-word linear or interleaved sequences
• Asynchronous output enable allows flexible bus control

Memory IC Applications

• High-performance system memory buffers
• Network router and switch data planes
• Telecommunications equipment caching
• Industrial control systems requiring fast data throughput

Memory IC Procurement Notes

Verify the specific suffix 'S150' matches the required 150 MHz speed grade and 'PF8' corresponds to the 100-TQFP package. Confirm RoHS compliance status as it varies by manufacturing date. Check for end-of-life notices from Renesas Electronics Corporation before finalizing procurement plans.

Memory IC Selection Notes

Select this component when zero bus turnaround latency is critical for system efficiency. Ensure the design accommodates separate 3.3V and 2.5V power domains. Verify that the 100-pin TQFP footprint fits the PCB layout constraints compared to BGA alternatives in the same family.
