71T75802S200BGI

Overview

The Renesas 71T75802S200BGI is a 18Mb (1M x 18) synchronous static random access memory IC utilizing Zero Bus Turnaround technology. It operates at a clock frequency of 200 MHz with a 3.2 ns access time, supporting high-speed parallel data transfer. The device functions within a supply voltage range of 2.375V to 2.625V and is housed in a 119-pin PBGA package measuring 14x22 mm. Designed for fully pipelined applications, it features positive clock-edge triggered registers for address, data, and control signals.

Feature Summary

• Zero Bus Turnaround architecture eliminates dead cycles between read and write operations
• Fully pipelined design with internally synchronized output buffer enable
• Supports individual byte write control via dedicated BW1-BW4 pins
• Includes boundary scan JTAG interface compliant with IEEE 1149.1

Applications

• High-performance system speed buffering
• Pipelined application data storage
• Depth expansion through multiple chip enables

Procurement Notes

Verify the specific suffix BGI against official Renesas documentation to confirm the 119-pin PBGA package configuration. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target design. Cross-reference the part number with current manufacturer status as legacy components may have limited availability or end-of-life implications.

Selection Notes

Select this component when a 200 MHz synchronous SRAM with ZBT functionality is required for 18-bit wide data paths. The 119-pin PBGA package suits space-constrained surface mount designs. Consider the 2.5V core and I/O voltage requirements during power budgeting. Verify compatibility with systems requiring single R/W control and burst capabilities for optimized throughput.

Part Context

This device belongs to the 71T75802 series of synchronous SRAMs manufactured by Renesas Electronics. The series offers various speed grades and package options, including TQFP and BGA configurations. The 71T75802 family is engineered to provide high-density memory solutions with zero bus turnaround capabilities for efficient data handling in complex digital systems.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Other speed grades within the 71T75802 series may serve as functional substitutes if timing constraints allow.
