71V67603S133BQGI

Overview

The IDT71V67603S133BQGI is a 9Mb Synchronous ZBT SRAM with a 256K x 36 organization. It operates at a maximum clock frequency of 133 MHz with a 4.2 ns access time. The device uses a 165-CABGA (13x15) package and supports a supply voltage range of 3.135V to 3.465V. It functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports high-speed synchronous parallel data transfer via Zero Bus Turnaround (ZBT) technology.
• Features a flow-through architecture for continuous data processing without wait states.
• Includes integrated clock registers and data registers for precise timing control.

Applications

• High-performance networking equipment requiring low-latency buffering.
• Industrial automation systems needing reliable volatile memory storage.
• Telecommunications infrastructure utilizing synchronous data interfaces.

Procurement Notes

Verify the component status as discontinued or obsolete through official Renesas channels before procurement planning. Confirm that the specific suffix BQGI matches the required 165-CABGA package and extended temperature grade. Ensure compatibility with existing board designs regarding pinout and electrical specifications, as direct replacements may require schematic adjustments.

Selection Notes

Select this component when a 36-bit wide data interface is necessary for system bus alignment. The 133 MHz speed class offers a balance between performance and power consumption for mid-range applications. Consider the physical dimensions of the 165-CABGA package during PCB layout to ensure adequate clearance and thermal management capabilities are maintained.
