71V65803S100BG8

Overview

The 71V65803S100BG8 is a synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 Megabits, organized as 512K words by 18 bits. The device supports a maximum clock frequency of 100 MHz with a typical access time of 5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 119-pin Plastic Ball Grid Array (PBGA) package measuring 14x22 mm. The component is designed for surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed parallel data transfer via a ZBT interface architecture that eliminates turnaround latency between read and write cycles.
• Utilizes synchronous pipeline architecture to achieve fast access times at elevated clock frequencies.
• Operates on a single 3.3V power supply rail compatible with standard logic levels.

Applications

• High-performance embedded systems requiring fast local memory buffering
• Industrial control equipment needing reliable volatile data storage
• Network infrastructure devices utilizing parallel SRAM interfaces

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS3 compliance and check for specific substrate or labeling changes documented in Product Change Notices. Ensure design-in compatibility with existing PCB footprints and voltage requirements before procurement.

Selection Notes

Select this part for applications requiring 18-bit wide data paths and synchronous timing. Compare against the 71V65603 series if a 36-bit organization is required instead. Verify that the 119-PBGA package dimensions fit the target enclosure constraints and thermal management strategy.

Part Context

This component belongs to the IDT/Renesas 71V65803 family of high-performance ZBT SRAMs. It shares architectural similarities with other members like the 71V65803S100BGG8 but differs in packaging and reel specifications. The family is characterized by low power consumption and high density relative to asynchronous alternatives.
