71V65603S100PFG

Overview

The Renesas Electronics Corporation 71V65603S100PFG is a 9 Mbit Synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM). It features a parallel interface with a memory organization of 256K x 36. The device supports a maximum clock frequency of 100 MHz and has an access time of 10 ns. It operates within a supply voltage range of 3.135 V to 3.465 V, with a maximum power supply current of 250 mA. The component is designed for surface mount installation in a TQFP-100 package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports synchronous single data rate operations with zero bus turnaround technology to eliminate dead cycles during read-write transitions.
• Features a pipelined architecture optimized for high-speed parallel data transfer.
• Operates on a standard 3.3V core voltage supply.

Applications

• High-performance embedded systems requiring fast random access memory
• Network infrastructure equipment
• Industrial control systems

Procurement Notes

Verify the specific suffix PFG against official datasheets to confirm the 10 ns access time and commercial temperature range, as other suffixes may indicate different speeds or industrial ratings. Confirm RoHS compliance status for the specific manufacturing lot, as legacy components may have varying environmental declarations. Check for End-of-Life notices from Renesas to ensure long-term availability for production needs.

Selection Notes

Select this component when a 9 Mbit capacity with a 36-bit wide data bus is required for synchronous applications. Ensure the design environment stays within the 0°C to +70°C operating range. Verify that the system logic levels are compatible with the 3.3V I/O requirements. Consider the TQFP-100 package dimensions for PCB layout constraints compared to alternative packages like BGA or LQFP.

Part Context

This part belongs to the 71V65603S series of ZBT SRAMs from Renesas. It shares architectural similarities with other members of the family but differs in speed grade and packaging. The 'PFG' suffix specifically denotes the TQFP-100 package variant with commercial temperature specifications, distinguishing it from industrial variants or different package types like BGA.

Replacement Considerations

Direct pin-to-pin replacements include the 71V65603S100BGI (BGA package) or 71V65603S100PFGI (Industrial temperature range). For functional equivalents with different interfaces, consider asynchronous SRAMs, though timing characteristics will differ significantly.
