71T75602S166BG8

Overview

The Renesas Electronics Corporation 71T75602S166BG8 is a synchronous static random-access memory (SRAM) device featuring an 18 Mbit storage capacity organized as 512K x 36. It operates with a maximum clock frequency of 166 MHz and achieves a minimum access time of 3.5 ns. The component utilizes a parallel interface and functions within a supply voltage range of 2.375 V to 2.625 V, with a maximum power consumption of 245 mA. It is housed in a 119-pin PBGA package designed for surface mount technology and supports standard single data rate operations.

Feature Summary

• Supports high-performance system speeds through pipelined output buffers and internal synchronization.
• Eliminates dead cycles between write and read operations using Zero Bus Turnaround technology.
• Features individual byte write control capabilities for precise data management.

Applications

• High-speed networking equipment requiring low-latency data buffering
• Telecommunications infrastructure systems
• Industrial automation controllers

Procurement Notes

This component is officially designated as End-of-Life by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Buyers must confirm the authenticity of the part number and check for potential obsolescence notices or product change notifications that may affect long-term support or compatibility.

Selection Notes

Engineers selecting this part should verify compatibility with existing 2.5V logic levels and ensure the PCB layout accommodates the 119-pin PBGA footprint. Consideration must be given to the end-of-life status when planning for future production runs, as replacement sourcing may require lead time adjustments or design modifications to accommodate alternative packages.

Part Context

The 71T75602 series belongs to Renesas' portfolio of synchronous ZBT SRAMs, designed for applications demanding high throughput and minimal bus turnaround latency. This specific model represents the 166 MHz speed grade variant within the 18 Mbit density class, offering a balance between performance and power efficiency for embedded memory tasks.

Replacement Considerations

Direct substitutes include the 71T75602S166PFG and IDT71T75602S166PF, which share identical electrical specifications but utilize different packaging formats such as TQFP instead of PBGA.
