71T75802S200PFG

Overview

The Renesas 71T75802S200PFG is a 18Mb (1M x 18) synchronous static random-access memory (SRAM) IC utilizing Zero Bus Turnaround (ZBT) technology. It operates with a parallel interface at a maximum clock frequency of 200 MHz, achieving a data access time of 3.2 ns. The device functions within a supply voltage range of 2.375V to 2.625V and supports an industrial operating temperature range from -40°C to +85°C. It is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Feature Summary

• Zero Bus Turnaround architecture eliminates dead cycles during bus turnaround between read and write operations.
• Fully pipelined design with internally synchronized output buffer enable for high-speed system performance.
• Supports four-word burst capability in either interleaved or linear modes.
• Includes individual byte write control pins for precise data masking.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment with high throughput demands
• Industrial automation controllers needing deterministic memory access

Procurement Notes

Verify the specific suffix PFG against official Renesas documentation to confirm package type and temperature grade. Confirm current production status as some variants in this series have been discontinued. Ensure compatibility with 2.5V I/O levels and check for moisture sensitivity handling requirements prior to assembly.

Selection Notes

Select this component when ZBT latency reduction is critical compared to standard synchronous SRAM. The 200 MHz speed grade suits applications requiring lower access times than the 150 MHz variants. Verify that the 100-TQFP package fits the board layout constraints and thermal management strategy for the intended industrial temperature range.

Part Context

This part belongs to the IDT 71T75802 family of synchronous SRAMs acquired by Renesas. The family is characterized by its ZBT technology, which improves system efficiency by removing wait states inherent in traditional synchronous memories. It serves as a bridge between asynchronous SRAM flexibility and synchronous DRAM density.

Replacement Considerations

Check for direct pin-compatible upgrades within the 71T75802 series, such as different speed grades (e.g., S133, S150). Verify if newer generations from Renesas offer equivalent functionality with improved availability or enhanced features.
