71V67903S80BQ8

Memory IC Overview

The Renesas 71V67903S80BQ8 is a 9-Mbit Synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM). It features a parallel interface with a memory organization of 512K x 18 bits. The device supports a maximum clock frequency of 100 MHz and has an access time of 8 ns. It operates within a supply voltage range of 3.135 V to 3.465 V. The component is housed in a 165-CABGA package measuring 13x15 mm, designed for surface mount installation.

Memory IC Feature Summary

• Supports high-speed synchronous data transfer via a single clock edge per data word.
• Provides wide 18-bit data bus width suitable for complex system architectures.
• Integrates on-chip clock buffers for improved signal integrity and timing control.

Memory IC Applications

• High-performance networking equipment requiring fast packet buffering.
• Industrial automation systems utilizing synchronous logic interfaces.
• Telecommunications infrastructure involving signal processing tasks.
• Embedded computing platforms demanding rapid volatile data storage access.

Memory IC Procurement Notes

Verify the specific suffix BQ8 against official datasheets to confirm the commercial temperature range and lead-free status. Confirm RoHS compliance requirements as older batches may differ. Check for End-of-Life notifications or Product Change Notices that might affect long-term availability. Ensure the 165-CABGA footprint matches the target PCB design constraints before ordering.

Memory IC Selection Notes

Select this component when an 18-bit data path is required for synchronous applications. Compare access times and power consumption against alternative SRAM families if lower latency is critical. Verify that the 3.3V operating voltage aligns with the system's I/O standards. Consider the physical dimensions of the CABGA package during mechanical layout planning.

Memory IC Part Context

This part belongs to the 71V67903 family of high-density synchronous SRAMs from Renesas. These devices are engineered for applications needing large buffer capacities with deterministic timing. The family typically includes variants with different speeds and packages to suit diverse board space and performance requirements.

Memory IC Replacement Considerations

Direct pin-to-pin replacements must match the 512K x 18 organization and 165-CABGA package. Verify that substitute parts support the same 100 MHz clock speed and 3.3V supply voltage. Consult manufacturer cross-reference lists for verified equivalents.
