71V65903S80BG8

Overview

The Renesas 71V65903S80BG8 is a synchronous SDR (ZBT) SRAM IC with a total storage capacity of 9Mb, organized as 512K x 18 bits. It features a parallel interface and an access time of 8 ns. The device operates on a single 3.3V power supply within the range of 3.135V to 3.465V. It is housed in a 119-pin PBGA package measuring 14x22 mm. The component supports surface mount installation and is rated for commercial operating temperatures from 0°C to 70°C.

Feature Summary

• Synchronous Single Data Rate architecture utilizing Zero Bus Turnaround technology for high-speed data transfer
• Parallel interface supporting pipelined operations for efficient memory access
• Single 3.3V power supply operation compatible with standard logic levels

Applications

• High-performance processor secondary cache systems
• Network infrastructure equipment requiring fast data buffering
• Industrial control systems needing reliable volatile memory storage

Procurement Notes

Verify the specific suffix BG8 against official datasheets to confirm the 119-PBGA package dimensions and pinout configuration. Ensure that the required 8 ns access time aligns with system timing constraints. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before ordering.

Selection Notes

Select this component when a 512K x 18 organization is required rather than alternative widths like 36-bit or 9-bit configurations found in the same family. The 8 ns speed grade offers a balance between performance and power consumption compared to faster variants. Verify that the PBGA footprint fits the target PCB layout constraints.

Part Context

This part belongs to the IDT 71V65xxx series of synchronous SRAMs manufactured by Renesas Electronics. The series includes various density and speed options, such as the 71V65703 and 71V65803 models. These devices are designed for applications demanding high bandwidth and low latency in embedded systems.

Replacement Considerations

Publicly documented substitutes include the 71V65803S133BQI. Verify electrical compatibility and pinout alignment before substitution.
