71V65603S133BGI

Overview

The 71V65603S133BGI is a synchronous pipelined static random-access memory (SRAM) 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 on a single 3.3V power supply within a range of 3.135V to 3.465V, drawing a maximum current of 300 mA. The component utilizes a parallel interface and is housed in a 119-pin PBGA package measuring 14x22 mm. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed data transfer via a 133 MHz synchronous pipeline architecture
• Provides wide 36-bit data bus width for efficient system integration
• Eliminates dead bus cycles during read-to-write or write-to-read transitions
• Operates on a standard 3.3V power supply for simplified design

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment such as routers and switches
• Industrial automation controllers demanding reliable real-time processing
• Telecommunications base stations and signal processing units

Procurement Notes

Verify the specific suffix BGI to confirm the 119-pin PBGA package configuration and lead-free status. Confirm RoHS compliance requirements against the latest manufacturer documentation. Check for end-of-life notices or production discontinuation announcements prior to finalizing procurement plans. Ensure compatibility with existing PCB footprints and soldering profiles for surface-mount assembly.

Selection Notes

Select this component when a 36-bit data path is required for high-throughput applications. The 133 MHz speed class suits designs needing low latency without complex asynchronous timing. Consider the 119-pin PBGA package constraints regarding board space and thermal management. Evaluate the 3.3V operation against system voltage rails to ensure direct compatibility without level shifting.

Part Context

This part belongs to the 71V65603S series of synchronous SRAMs designed for ZBT (Zero Bus Turnaround) operations. The series targets applications needing large buffer memories with predictable access times. The 133BGI variant specifically denotes the 133 MHz speed grade and the PBGA package type. It serves as a high-density memory solution replacing older asynchronous devices in modern digital systems.

Replacement Considerations

Check for official substitute part numbers provided by Renesas Electronics if this component is discontinued. Verify pinout compatibility and electrical specifications before substituting with similar parts from other manufacturers.
