71T75802S166BG

Overview

The Renesas Electronics Corporation 71T75802S166BG is a synchronous static random access memory (SRAM) device organized as 1 megabit by 18 bits, providing an 18 Mbit storage capacity. It operates with a maximum clock frequency of 166 MHz and features a typical access time of 3.5 ns. The component utilizes a parallel interface and requires a core supply voltage ranging from 2.375 V to 2.625 V. Maximum power consumption is specified at 245 mA. It is housed in a 119-pin PBGA package measuring 14x22 mm and supports surface mount installation. The device functions within an operating temperature range of 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 system design by removing the need for separate output enable signals
• Internally synchronized output buffer enable registers address, data, and control signals for pipelined applications

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment real-time engines
• Network infrastructure hardware

Procurement Notes

Verify current availability status as this component may be subject to discontinuance or limited supply conditions. Confirm that the specific 119-pin PBGA package variant matches your board layout requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Check for any recent product change notifications regarding labeling or packaging updates before finalizing procurement orders.

Selection Notes

Select this part when a 18 Mbit synchronous SRAM with ZBT technology is required for high-speed parallel data handling. The 166 MHz speed grade suits applications needing sub-4 ns access times. Verify that the 0°C to +70°C commercial temperature range meets your environmental constraints. Consider the 119-pin BGA footprint during PCB design to ensure adequate routing space and thermal management capabilities for the specified power dissipation levels.

Part Context

This component belongs to the 71T75802 series of synchronous SRAMs designed for high-performance computing environments. The series offers various speed grades and package options to accommodate different system bandwidth and physical size requirements. As a ZBT device, it optimizes bus efficiency compared to traditional synchronous memories, making it suitable for complex digital signal processing and communication protocols.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Cross-reference speed grades and package dimensions carefully. Verify compatibility with existing system timing constraints before transitioning to alternative components.
