71V65903S85BG8

Overview

The 71V65903S85BG8 is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 Megabits organized as 512K words by 18 bits. The device utilizes a parallel interface with an access time of 8.5 nanoseconds and operates within a supply voltage range of 3.135 to 3.465 volts. It is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 millimeters.

Feature Summary

• Supports high-speed data transfer via a parallel interface architecture
• Provides reliable volatile data retention for system operations
• Designed for surface-mount installation on printed circuit boards

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing synchronous logic

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm specific suffix designations match exact package and thermal requirements. Check current manufacturing status as legacy components may face discontinuation. Ensure compatibility with existing board layouts regarding pin configurations and power delivery specifications before procurement.

Selection Notes

Select this model when a 9Mb synchronous SRAM with 18-bit width is required. Compare access times against system clock speeds to ensure timing compliance. Evaluate the PBGA package dimensions against available PCB real estate. Consider alternative variants if different access speeds or organizational structures better suit the specific application constraints.

Part Context

This component belongs to the 71V65903 series of synchronous SRAM devices from Renesas. The series typically includes various speed grades and packaging options to accommodate diverse design needs.
