71V65903S80BQG

Overview

The Renesas Electronics Corporation 71V65903S80BQG is a synchronous static random-access memory (SRAM) integrated circuit belonging to the ZBT family. It provides a total storage capacity of 9 Megabits, organized as 512K words by 18 bits. The device features a parallel interface with an access time of 8 nanoseconds and operates on a single 3.3V power supply within the range of 3.135V to 3.465V. It is housed in a 165-ball Cavity Ball Grid Array (CABGA) package measuring 13x15 mm. The component supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Synchronous Single Data Rate (SDR) architecture for high-speed data transfer
• ZBT technology ensuring zero wait state operation
• Parallel interface supporting wide data bus configurations

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial control equipment needing reliable volatile memory
• Telecommunications infrastructure utilizing synchronous logic

Procurement Notes

Verify the specific suffix 'G' against official Renesas documentation to confirm lead-free status and RoHS compliance, as standard variants may differ. Confirm package dimensions match the 165-CABGA specification. Check current manufacturing status, as this series has faced end-of-life notices for similar part numbers. Ensure design-in compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when a 9Mb synchronous SRAM with an 18-bit data width is required. The 8ns access time suits applications demanding rapid data retrieval. The CABGA package offers thermal advantages over TQFP options. Verify voltage requirements align with the 3.3V system rail. Consider the operating temperature range if deployed in harsh environments.
