71V65803S100BQI

Overview

The Renesas Electronics Corporation 71V65803S100BQI is a synchronous Single Data Rate Zero Bus Transition SRAM IC with a total storage capacity of 9 Megabits. The memory organization is structured as 512K words by 18 bits, utilizing a parallel interface. It operates at a maximum clock frequency of 100 MHz with an access time of 5 nanoseconds. The device requires a supply voltage ranging from 3.135V to 3.465V and supports an industrial operating temperature range of -40°C to +85°C. It is housed in a 165-CABGA package measuring 13x15 millimeters.

Feature Summary

• Supports high-speed data transfer via a 100 MHz synchronous parallel interface
• Utilizes Zero Bus Transition technology to reduce power consumption and signal noise
• Provides reliable operation within the industrial temperature range of -40°C to +85°C

Applications

• High-performance embedded systems requiring fast random access memory
• Industrial control units and automation equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as it may vary by production batch. Check for specific packaging requirements such as tray quantities. Ensure compatibility with existing PCB footprints and soldering profiles. Validate that the lead-free designation matches project specifications before finalizing orders.

Selection Notes

Select this component when a 9Mb synchronous SRAM with a 165-pin BGA footprint is required. Compare against other speed grades within the 71V65803 family based on system timing constraints. Consider the 18-bit data width for applications needing wide data buses without external multiplexing. Evaluate thermal management needs given the industrial temperature rating and power dissipation characteristics of the CABGA package.
