71T75802S133BGG

Overview

The Renesas 71T75802S133BGG is a 18 Mbit synchronous static random-access memory (SRAM) organized as 1M x 18. It operates with a maximum clock frequency of 133 MHz and features a 4.2 ns access time. The device utilizes a 2.5V core voltage supply ranging from 2.375V to 2.625V. It employs Zero Bus Turnaround (ZBT) technology for high-performance parallel data transfer. The component is housed in a 119-pin PBGA package measuring 14x22 mm.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations
• Single R/W control pin simplifies interface logic requirements
• Internally synchronized output buffer enable removes external OE control needs
• Supports individual byte write capabilities via BW1-BW4 control signals

Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring low-latency buffering
• Industrial automation controllers
• Embedded systems demanding pipelined memory access

Procurement Notes

Verify the specific suffix BGG against official Renesas documentation to confirm the exact package type and temperature range. Confirm RoHS compliance status through current datasheets, as manufacturing processes may evolve. Check for End-of-Life notifications or Product Change Notices prior to procurement decisions.

Selection Notes

Select this component when system design requires ZBT SRAM performance with a 133 MHz interface speed. Ensure the PCB layout supports the 119-pin PBGA footprint dimensions. Verify that the power supply network can maintain the required 2.5V core voltage stability under peak current conditions during burst operations.

Part Context

This part belongs to the 71T75802 series of 2.5V CMOS synchronous SRAMs. The series offers various speed grades and package options, including TQFP and PBGA configurations. The 71T75802 family is designed for applications needing high throughput without bus turnaround delays, serving as a bridge between fast processors and slower memory subsystems.

Replacement Considerations

Consult official Renesas substitution guides for compatible alternatives. Verify pin compatibility and electrical specifications before replacing. No direct public substitute part numbers are confirmed in available documentation.
