Overview
The 71V65703S85BQG8 is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 Megabits, organized as 256K words by 36 bits. The device utilizes a parallel interface with an access time of 8.5 nanoseconds and operates within a supply voltage range of 3.135V to 3.465V. It is housed in a 165-CABGA package measuring 13x15 mm and supports surface mount installation.
Feature Summary
- Supports Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read-write transitions.
- Includes registers for address, data-in, and control signals to enhance interface efficiency.
- Provides flow-through output without an output data register for direct data availability.
Applications
- High-performance embedded systems requiring fast parallel memory access
- Network infrastructure equipment utilizing ZBT SRAM interfaces
- Industrial control systems operating within specified temperature ranges
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) requirements for handling. Check for recent product change notices regarding labeling or substrate modifications. Ensure compatibility with existing PCB footprints for the 165-CABGA package before procurement.
Selection Notes
Select this component for designs requiring 36-bit wide data paths and synchronous parallel interfaces. Compare against alternative packages such as PBGA if board space constraints differ. Evaluate thermal performance within the -40°C to 85°C operating range. Consider lead-free specifications for environmental compliance in final assembly processes.
Part Context
This part belongs to the 71V65703 family of ZBT synchronous SRAMs from Renesas. It shares architectural similarities with other variants like the 71V65703S85BQI but differs in packaging and suffix designations. The CABGA package offers specific mechanical advantages over BGA alternatives for certain mounting applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin-to-pin compatibility with similar 256K x 36 ZBT SRAM devices from other manufacturers if cross-sourcing is necessary.
