71T75802S100BGI

Overview

The Renesas 71T75802S100BGI is a synchronous static random-access memory (SRAM) integrated circuit belonging to the Zero Bus Turnaround (ZBT) family. It features an 18-megabit storage capacity organized as 1M x 18 bits. The device operates with a maximum clock frequency of 100 MHz and provides a typical access time of 5 ns. It utilizes a parallel interface and requires a core supply voltage ranging from 2.375 V to 2.625 V. The component is housed in a 119-pin PBGA package measuring 14x22 mm and supports an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Zero Bus Turnaround architecture eliminates dead cycles during bus turnaround between read and write operations.
• Internally synchronized output buffer enable removes the requirement for external Output Enable control signals.
• Single Read/Write control pin simplifies interface logic by combining address, data, and control signal registers.
• Supports four-word burst capabilities in either interleaved or linear modes for efficient data transfer.

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment and routers
• Industrial automation controllers
• Telecommunications base stations

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as historical records indicate non-compliance for some variants. Check moisture sensitivity level handling requirements before assembly. Validate package dimensions against PCB footprint specifications. Ensure supply chain stability as this specific part number may be subject to discontinuation notices.

Selection Notes

Select this component when system design demands high-speed synchronous memory with minimal bus turnaround latency. Compare against other ZBT SRAM options based on required access times and organizational formats. Consider thermal performance within the specified industrial temperature range. Evaluate power consumption characteristics relative to available supply voltage margins. Assess physical package constraints against available board space.
