71T75802S200BGGI8

Overview

The Renesas 71T75802S200BGGI8 is a 18 Mbit synchronous static random access memory (SRAM) organized as 1M x 18. It operates with a clock frequency of 200 MHz and features an access time of 3.2 ns. The device utilizes a parallel interface and requires a supply voltage between 2.375V and 2.625V. It is housed in a 119-pin PBGA package measuring 14x22 mm. The component supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations.
• Internally synchronized output buffer enable removes the need for external OE control.
• Single R/W control pin simplifies interface logic requirements.
• Supports four-word burst capability in interleaved or linear modes.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory in network processing systems
• Digital signal processing applications requiring low latency

Procurement Notes

Verify the specific suffix BGGI8 against the manufacturer datasheet to confirm the exact package dimensions and moisture sensitivity level. Confirm RoHS compliance status, as documentation indicates variations across the product family. Check for obsolescence notices, as this part number has been marked as obsolete in some distributor records. Ensure the source document explicitly lists this full part number to avoid substitution errors.

Selection Notes

Select this component when a 200 MHz synchronous SRAM with ZBT technology is required for high-throughput parallel interfaces. The 119-PBGA package is suitable for surface mount applications with space constraints. Consider the 2.5V core voltage requirement for power management design. Verify that the 1M x 18 organization matches the system data bus width requirements.
