IDT71V65602S150BG

Memory IC Overview

The IDT71V65602S150BG is a 9 Megabit synchronous SRAM manufactured by Renesas Electronics Corporation. It features a 256K x 36 memory organization and supports clock frequencies up to 150 MHz with a 3.8 ns access time. The device utilizes Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read/write transitions. It operates on a 3.3V core supply and a separate 2.5V I/O supply, housed in a 119-ball BGA package.

Memory IC Feature Summary

• Zero Bus Turnaround architecture eliminates dead cycles between read and write operations
• Pipelined outputs with internally synchronized output buffer enable
• Single R/W control pin for simplified interface management
• On-chip burst counter supporting linear or interleaved sequences

Memory IC Applications

• High-performance system speed applications requiring 150MHz operation
• Systems utilizing 2.5V I/O logic levels
• Burst data transfer implementations

Memory IC Procurement Notes

Verify the specific suffix BG against official documentation to confirm the 119-pin BGA package configuration. Confirm that the 2.5V I/O supply requirement aligns with the target system design. Check current product status as discontinuance notices may apply to this component family.

Memory IC Selection Notes

Select this component when ZBT technology is required to maximize bus throughput without turnaround latency. Ensure the host system can provide a dedicated 2.5V supply for the VDDQ pins. Verify that the 119-ball BGA footprint matches the PCB layout constraints.

Memory IC FAQ

How does the ZBT feature improve performance?

It eliminates dead bus cycles when turning the bus around between reads and writes, allowing continuous data transfer.

What is the function of the ADV/LD signal?

ADV/LD loads new addresses when low or increments the internal burst counter when high during active bursts.
