71V65603S100BQG8

Overview

The 71V65603S100BQG8 is a synchronous ZBT SRAM manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit organized as 256K x 36. The device supports a maximum clock frequency of 100 MHz with an access time of 5 ns. It operates on a single 3.3V power supply, ranging from 3.135V to 3.465V. The component utilizes a parallel interface and is housed in a 165-CABGA package measuring 13x15 mm. It is designed for surface mount installation and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Eliminates dead bus cycles during read-to-write or write-to-read transitions using Zero Bus Turnaround (ZBT) technology.
• Integrates address, data-in, and control signal registers to support high-speed synchronous operations.
• Provides pipelined outputs to maintain continuous data throughput during burst mode accesses.

Applications

• High-performance processor secondary cache systems
• Network routing equipment requiring fast memory access
• Industrial automation controllers

Procurement Notes

Verify the specific suffix BQG8 against official Renesas documentation to confirm the exact package dimensions and moisture sensitivity level. Confirm RoHS compliance status directly with the manufacturer, as legacy listings may vary. Check for active production status or obsolescence notices prior to procurement planning.

Selection Notes

Select this component when a 36-bit wide data path is required for system architecture compatibility. Ensure the design accommodates the 165-pin CABGA footprint and thermal requirements. Verify that the 3.3V core voltage aligns with the target board's power distribution network constraints.
