71T75802S166BGGI8

Overview

The Renesas Electronics Corporation 71T75802S166BGGI8 is a 18 Mbit synchronous static random access memory (SRAM) organized as 1M x 18. It operates with a maximum clock frequency of 166 MHz and features an access time of 3.5 ns. The device utilizes a parallel interface and functions within a supply voltage range of 2.375 V to 2.625 V, with a maximum power current of 265 mA. It is housed in a 119-pin PBGA package measuring 14x22 mm. The component supports single data rate (SDR) operations and is rated for commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations.
• Single R/W control pin simplifies bus control by eliminating the need for separate output enable signals.
• Internally synchronized output buffer enable registers address and control signals for fully pipelined applications.
• Supports four-word burst capability in either interleaved or linear modes.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems operating within standard commercial temperature limits

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints for the 119-pin PBGA package. Review datasheet specifications for voltage tolerances and thermal management needs before integration into final designs.

Selection Notes

Select this component when zero bus turnaround performance is critical for system throughput. Consider the 119-pin PBGA package for space-constrained surface mount applications. Verify that the 2.5V core and I/O voltage requirements align with the target system power rails. Evaluate the 166 MHz speed grade against alternative parts if higher frequencies are required.
