71V3559S80BQ

Overview

The 71V3559S80BQ is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 megabits, organized as 256K words by 18 bits. The device features a parallel interface with an access time of 8 nanoseconds and operates within a supply voltage range of 3.135 to 3.465 volts. It is housed in a 165-pin CABGA package measuring 13x15 millimeters and supports surface-mount installation.

Feature Summary

• Supports synchronous single data rate operations for high-speed data transfer
• Provides true dual-port memory architecture allowing independent port access
• Includes on-chip port arbitration logic for efficient resource management

Applications

• High-performance computing systems requiring fast memory access
• Industrial equipment control units
• Telecommunications infrastructure networking devices

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity handling procedures before assembly. Check for RoHS compliance variations across production batches. Ensure compatibility with existing board layouts regarding the 165-CABGA footprint. Validate electrical specifications against current design requirements.

Selection Notes

Evaluate system timing constraints against the 8 ns access speed. Consider power consumption levels relative to available cooling solutions. Assess physical space limitations for the 165-pin BGA configuration. Compare performance metrics with alternative synchronous SRAM options if higher density or different organization is required. Verify temperature range suitability for the intended operating environment.
