71V65603S150BQG8

Overview

The 71V65603S150BQG8 is a synchronous SDR ZBT SRAM IC with a 9Mb capacity organized as 256K x 36. It operates at a clock frequency of 150 MHz with a 3.8 ns access time. The device uses a parallel interface and requires a supply voltage between 3.135V and 3.465V. It is housed in a 165-CABGA package measuring 13x15 mm and supports surface mount installation.

Feature Summary

• Zero bus turnaround architecture eliminates dead cycles during read-write transitions
• Integrated address, data-in, and control signal registers for synchronous operation
• Flow-through output configuration without output data registers
• Supports burst mode providing four cycles of data for a single address

Applications

• High-performance processor secondary cache systems
• Network infrastructure equipment requiring fast memory access
• Industrial automation controllers
• Telecommunications base stations

Procurement Notes

Verify the specific suffix BQG8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status and check for product discontinuance notifications prior to procurement. Ensure design compatibility with the 165-CABGA footprint and verify operating temperature range requirements.

Selection Notes

Select this component when zero bus turnaround performance is critical for system throughput. The 36-bit data width suits applications requiring wide data buses without external multiplexing. Verify that the 150 MHz speed grade meets the target system clock requirements and that the CABGA package fits the available PCB real estate constraints.

Part Context

This part belongs to the 71V65603 family of synchronous SRAMs designed by Renesas Electronics. The family utilizes ZBT technology to optimize data transfer efficiency. Variants within the series differ primarily in speed grades and package options while maintaining the same core memory organization and functional architecture.
