71V65603S100BQ

Overview

The 71V65603S100BQ is a synchronous Single Data Rate Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a total storage capacity of 9 Megabits, organized as 256K words by 36 bits. The device supports a maximum clock frequency of 100 MHz with a typical access time of 5 nanoseconds. It operates within a supply voltage range of 3.135V to 3.465V and utilizes a parallel interface. The component is housed in a 165-CABGA package measuring 13x15 mm and is designed for surface mount installation.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead bus cycles during read-to-write or write-to-read transitions.
• Integrated registers for address, data-in, and control signals to support high-speed synchronous operation.
• Flow-through output architecture provides immediate data availability without an additional output register stage.
• Supports burst mode operations to deliver multiple data cycles for a single presented address.

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment and routers
• Industrial automation controllers
• Telecommunications base stations

Procurement Notes

Verify the specific suffix 'BQ' against official Renesas documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status as it varies by manufacturing date and region. Check for End-of-Life notices or Product Change Notifications regarding this specific part number before finalizing procurement plans.

Selection Notes

Select this component when system design requires ZBT SRAM with a 36-bit data width and 100 MHz synchronous performance. Ensure the PCB layout accommodates the 165-CABGA footprint. Verify that the power supply rails strictly maintain the 3.135V to 3.465V operating range to guarantee signal integrity and timing specifications.

Part Context

This part belongs to the 71V65603 family of ZBT Synchronous SRAMs. It shares architectural similarities with other variants in the series but differs in speed grade and physical packaging. The 100 MHz speed bin distinguishes it from faster 133 MHz or 150 MHz models, offering a balance between performance and power consumption for mid-range applications.
