71V65603S133BGG8

Overview

The 71V65603S133BGG8 is a synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 Megabits, organized as 256K words by 36 bits. The device supports a maximum clock frequency of 133 MHz with a typical access time of 4.2 ns. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 119-pin Plastic Ball Grid Array (PBGA) package measuring 14x22 mm. The component is designed for surface mount installation.

Feature Summary

• Supports high-speed parallel data transfer via a ZBT interface architecture
• Utilizes synchronous SDR technology for efficient pipeline operation
• Provides wide 36-bit data bus width for high-bandwidth applications

Applications

• High-performance networking equipment memory buffers
• Telecommunications base station signal processing
• Industrial automation control systems requiring fast data access

Procurement Notes

Verify the specific suffix BGG8 to confirm the 119-pin PBGA package and tape-and-reel packaging format. Confirm RoHS compliance status as documentation indicates variations across the product family. Check for End-of-Life notices, as this component series has been subject to discontinuation announcements. Ensure the required operating temperature range matches the industrial specifications provided in the official datasheet.

Selection Notes

Select this component when a 36-bit data path is required for system architecture compatibility. The 133 MHz speed grade offers a balance between performance and power consumption compared to faster variants. Consider the physical dimensions of the 119-PBGA package during PCB layout planning. Verify that the 3.3V logic levels align with the host processor's I/O standards without requiring additional level shifting.

Part Context

This part belongs to the IDT 71V65603 family of synchronous SRAMs, originally developed by Integrated Device Technology before its acquisition by Renesas. The family is characterized by zero bus turnaround cycles, which maximize throughput efficiency on wide data buses. This specific variant utilizes a ball grid array form factor suitable for dense board layouts.
