71V65603S133BGI8

Overview

The 71V65603S133BGI8 is a synchronous static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The device supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates within a voltage range of 3.135 V to 3.465 V and utilizes a parallel interface. The component is housed in a 119-pin PBGA package measuring 14x22 mm, suitable for surface mount technology.

Feature Summary

• Supports high-speed data transfer via a 133 MHz synchronous clock interface
• Provides wide 36-bit data bus organization for efficient word processing
• Utilizes Zero Bus Turnaround (ZBT) technology to minimize wait states

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems
• Industrial control systems demanding rapid data acquisition

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential supply chain variations. Confirm RoHS compliance status as documentation indicates non-compliance in some regions. Check for moisture sensitivity level requirements during handling and storage to prevent damage. Ensure the specific BGA package variant matches the target PCB footprint design constraints.

Selection Notes

Select this component when a 36-bit wide data path is required for system architecture compatibility. Consider the 133 MHz speed grade if higher throughput than slower variants is necessary. Evaluate the 119-pin PBGA package size against available board space. Compare power consumption specifications against other SRAM options to ensure thermal management capabilities are sufficient for the application environment.

Part Context

This part belongs to the 71V65603 series of synchronous ZBT SRAMs from Renesas. The series offers various speed grades and package options to suit different performance and form factor needs. The 71V65603S133BGI8 specifically targets applications needing high bandwidth and low latency in a compact surface-mount package.

Replacement Considerations

The 71V65603S133PFGI is a pin-compatible alternative in a TQFP-100 package. The 71V65603S133BQGI is another BGA option but uses a 165-pin CABGA package. Verify electrical parameters and physical dimensions before substituting.
