71T75802S133BGG8

Overview

The Renesas Electronics Corporation 71T75802S133BGG8 is a 18 Mbit synchronous static random access memory (SRAM) device organized as 1M x 18. It operates with a maximum clock frequency of 133 MHz and features a 4.2 ns access time. The component utilizes a parallel interface and requires a supply voltage between 2.375 V and 2.625 V. It is housed in a 119-pin PBGA package measuring 14x22 mm. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles during bus turnaround between read and write operations.
• Internally synchronized output buffer enable removes the requirement for external OE control signals.
• Single R/W control pin simplifies interface logic by combining read and write command functions.
• 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 commercial temperature ranges

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as this specific variant may not meet current environmental standards. Validate package integrity upon receipt, as moisture sensitivity level 3 requires strict handling protocols. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before integration into production workflows.

Selection Notes

Select this component when a 1M x 18 organization is required with ZBT performance characteristics. Ensure the design accommodates the 119-pin BGA footprint and 2.5V core voltage constraints. Consider thermal management for the 0°C to 70°C operating range. Verify that the system clock does not exceed 133 MHz to maintain the specified 4.2 ns access timing parameters.
