71T75802S166BGI

Overview

The Renesas Electronics Corporation 71T75802S166BGI 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 a 3.5 ns access time. The device utilizes a parallel interface and functions within a supply voltage range of 2.375 V to 2.625 V. It is housed in a 119-pin PBGA package measuring 14x22 mm. The component supports surface mount installation and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations.
• Fully pipelined design with internally synchronized output buffer enable for simplified control.
• Supports four-word burst capability in either interleaved or linear modes.
• Includes individual byte write control for precise data masking.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment demanding low-latency memory access
• Industrial automation controllers utilizing ZBT technology
• Telecommunications base stations processing high-speed data streams

Procurement Notes

Verify the specific suffix BGI against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes define package and temperature variants. Confirm availability status directly with authorized distributors, as this part may be subject to discontinuation notices. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the current datasheet before integration into production schedules.

Selection Notes

Select this component when system requirements demand a 18 Mbit capacity with a 166 MHz operational speed. The 1M x 18 organization is suitable for applications needing wide data buses without external parity generation overhead. Consider the -40°C to +85°C industrial temperature rating for robust environmental performance. The 119-pin PBGA package offers a compact footprint for space-constrained designs compared to larger QFP alternatives.

Part Context

This SRAM belongs to the 71T75802 series, which implements Zero Bus Turnaround technology to maximize throughput. The series is designed for high-speed parallel data transfer in complex digital systems. The 166 MHz variant represents a high-frequency option within the family, balancing speed and power consumption for demanding embedded applications requiring reliable synchronous memory solutions.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully when considering alternative manufacturers. Verify that any substitute maintains compatibility with the 2.5V core and I/O voltage requirements.
