71V3559S85BQG8

Overview

The 71V3559S85BQG8 is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface and a total storage capacity of 4.5 megabits, organized as 256K words by 18 bits. The device supports an access time of 8.5 nanoseconds and operates within a supply voltage range of 3.135 volts to 3.465 volts. It is housed in a 165-pin CABGA package measuring 13x15 millimeters.

Feature Summary

• Supports synchronous SDR operation with a parallel interface for high-speed data transfer
• Provides 4.5Mb storage capacity organized as 256K x 18 configuration
• Features fast 8.5ns access time for efficient system performance
• Operates on a single 3.3V power supply with specified voltage tolerances

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems needing reliable volatile memory storage

Procurement Notes

Verify the exact suffix BQG8 against official Renesas documentation to confirm package type and reel specifications. Confirm RoHS compliance status as some variants may not meet current environmental standards. Check for end-of-life notices or product change notifications that may affect long-term availability. Ensure the supplier provides valid traceability documents for this specific part number.

Selection Notes

Select this component when a 4.5Mb synchronous SRAM with an 18-bit word width is required. The 165-CABGA package is suitable for surface-mount applications with specific board space constraints. Consider the 8.5ns access speed for timing requirements in synchronous designs. Verify that the 3.3V I/O levels match the target system logic voltages.

Part Context

This part belongs to the 71V3559 family of synchronous SRAMs from Renesas. It shares core architectural features with other variants in the series but differs in package and speed grade. The 71V3559 series is designed for applications demanding high bandwidth and low latency using standard parallel interfaces.

Replacement Considerations

Check for direct substitutes within the 71V3559 family such as 71V3559S85BQ or IDT71V3559S85BQG8. Verify pin compatibility and electrical parameters before substitution. Consult official cross-reference lists for approved replacements.
