71V65603S150BG8

Overview

The Renesas Electronics Corporation 71V65603S150BG8 is a synchronous static random-access memory (SRAM) integrated circuit featuring Zero Bus Turnaround (ZBT) technology. It provides a storage capacity of 9 Mbit organized as 256K x 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 3.8 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and utilizes a parallel interface. The component is housed in a 119-pin PBGA package measuring 14x22 mm.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture for high-speed data transfer
• Single Data Rate (SDR) synchronous operation
• 3.3V I/O compatibility

Applications

• High-speed buffering
• Caching applications

Procurement Notes

Verify the authenticity of the supplier, as this specific part number may be subject to obsolescence notices or discontinuation by the manufacturer. Confirm the package type matches the required PCB footprint and ensure compliance with current environmental regulations, as older batches may not meet RoHS standards. Check for moisture sensitivity level requirements during handling and storage.

Selection Notes

Select this component when a 256K x 36 bit organization is required for synchronous memory interfaces. It is suitable for designs needing ZBT performance at 150 MHz speeds. Ensure the system design accommodates the 119-pin BGA package constraints and the specific 3.3V power supply requirements.

Part Context

This part belongs to the 71V65603 series of synchronous SRAMs from Renesas. Variants in this series differ primarily in speed grades (e.g., 100 MHz, 133 MHz) and package types (TQFP vs. PBGA). The 150BG8 designation specifically indicates the 150 MHz speed grade and the 119-pin PBGA package configuration.

Replacement Considerations
