71T75802S100BG

Overview

The 71T75802S100BG is a 18 Mbit synchronous static random access memory (SRAM) organized as 1M x 18. It operates with a maximum clock frequency of 100 MHz and features a typical access time of 5 ns. The device utilizes a parallel interface and functions within a supply voltage range of 2.375 V to 2.625 V. It is housed in a 119-pin PBGA package measuring 14x22 mm, designed for surface mount technology applications.

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 system design by combining read and write signals
• Positive clock-edge triggered registers support fully pipelined applications

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment real-time engines
• Network infrastructure devices needing low-latency memory access

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for recent product change notifications regarding packaging or material updates. Ensure storage conditions meet specified humidity requirements to prevent damage before soldering.

Selection Notes

Select this model when a 100 MHz synchronous SRAM with ZBT technology is required. Compare against other speed grades like 133 MHz or 166 MHz variants if higher performance is needed. Consider the 119-pin BGA package constraints for PCB layout. Verify that the 2.5V core and I/O voltage levels match the target system power rails.
