70T3799MS166BBG

Memory IC Overview

The 70T3799MS166BBG is a high-speed synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features an 18 Mbit density organized as 128K words by 72 bits, providing robust data handling for complex systems. The device supports a maximum clock frequency of 166 MHz with a typical access time of 3.6 ns, ensuring rapid data throughput. It operates on a single 2.5V power supply and utilizes a 324-pin plastic ball grid array (PBGA) package measuring 19x19 mm. This component is designed for parallel interface applications requiring simultaneous independent access to shared memory locations.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location from two separate ports.
• Synchronous operation ensures precise timing alignment across both ports using a common clock signal.
• Pipelined or flow-through output architecture options optimize performance for specific data flow requirements.

Memory IC Applications

• High-performance networking equipment requiring low-latency packet buffering
• Telecommunications infrastructure utilizing fast data switching and routing
• Industrial automation systems demanding reliable real-time data processing

Memory IC Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm RoHS compliance and moisture sensitivity level prior to procurement. Ensure the supplier provides official documentation matching the exact suffix BBG. Check for any product change notifications regarding packaging or pinout modifications before finalizing orders.

Memory IC Selection Notes

Select this part when simultaneous bidirectional data access is required without arbitration delays. The 166 MHz speed rating suits high-bandwidth applications exceeding standard SRAM capabilities. Verify that the 324-pin PBGA package fits the target PCB layout constraints. Ensure the system design accommodates the 2.5V I/O voltage levels and thermal dissipation requirements of the BGA form factor.

Memory IC Part Context

This component belongs to the 70T3799M series of synchronous dual-port SRAMs. The series offers various speed grades and organizational configurations to meet diverse memory bandwidth needs. Originally developed by Integrated Device Technology (IDT), the product line was integrated into Renesas Electronics' portfolio following corporate acquisitions. The 70T3799 variant specifically targets applications needing wide data buses and high-speed synchronization.

Memory IC Replacement Considerations

Consult official manufacturer documentation for qualified substitute part numbers. Cross-reference speed grades and pin compatibility if considering alternative vendors. Verify that any replacement maintains the 324-pin PBGA footprint and 2.5V operating voltage specifications.
