70T3719MS166BBG

Memory IC Overview

The Renesas Electronics Corporation 70T3719MS166BBG is a high-speed synchronous dual-port static RAM. It features a memory organization of 256K x 72 bits, providing a total density of 18 megabits. The device supports an I/O clock frequency of 166 MHz with a typical access time of 3.6 ns. It operates on a 2.5V core supply voltage and accepts selectable 3.3V or 2.5V I/O supplies. The component is housed in a 324-pin PBGA package.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location by two separate controllers.
• Supports selectable pipelined or flow-through output modes for optimized data throughput flexibility.
• Includes interrupt and collision detection flags to manage bus arbitration and data integrity.
• Features automatic power-down capabilities controlled by chip enable signals for low standby power consumption.

Memory IC Applications

• Network routers and switches requiring high-bandwidth packet buffering
• Telecommunications base stations handling burst data flows
• Industrial automation systems needing fast bidirectional data exchange

Memory IC Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm RoHS compliance and moisture sensitivity levels prior to procurement. Ensure the specific suffix matches required voltage and temperature grades. Check for valid replacement part numbers if the original is no longer produced.

Memory IC Selection Notes

Select this component when simultaneous dual-controller access to shared memory is required. Verify that the 324-pin BGA footprint fits the PCB layout constraints. Ensure the system design supports the 2.5V core and selectable I/O voltage requirements. Consider the 166 MHz speed grade against system timing budgets.

Memory IC Part Context
