70T3719MS133BBG

Memory IC Overview

The Renesas 70T3719MS133BBG is a high-speed synchronous dual-port static random-access memory (SRAM) organized as 256K x 72 bits, providing a total storage capacity of 18 Mbit. It operates with a maximum clock frequency of 133 MHz and features an access time of 4.2 ns. The device utilizes a parallel interface and supports selectable pipelined or flow-through output modes. It requires a 2.5V core power supply and offers LVTTL-compatible I/Os that can be powered by either 3.3V or 2.5V. 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 from both ports without additional logic.
• Supports selectable pipelined or flow-through output modes for optimized data flow in burst applications.
• Includes interrupt and collision detection flags along with counter enable and repeat features.
• Features automatic power-down capabilities controlled by chip enables to achieve low standby power consumption.

Memory IC Applications

• High-speed networking equipment requiring bidirectional data flow
• Telecommunications systems utilizing burst data processing
• Industrial automation controllers needing fast dual-access memory
• Embedded systems requiring synchronous SRAM with JTAG support

Memory IC Procurement Notes

Verify the specific suffix BBG against official Renesas documentation to confirm the exact package type and temperature range. Confirm current production status as some variants in this series may have end-of-life notifications. Ensure voltage compatibility between the 2.5V core and selectable 3.3V/2.5V I/O supplies matches your system design requirements before ordering.

Memory IC Selection Notes

Select this component when simultaneous read/write access to shared memory is required for high-performance applications. Consider the 324-pin BGA package constraints for PCB layout and thermal management. Evaluate the need for JTAG functionality if debugging or boundary scan testing is necessary during development. Compare power consumption profiles between pipelined and flow-through modes based on system throughput needs.

Memory IC Part Context

This part belongs to the Renesas 70T3719M family of synchronous dual-port RAMs. These devices are designed for applications demanding high bandwidth and low latency. The family typically includes variations in organization and package types, such as the 70T3799 variant which offers a 128K x 72 organization. All members share similar control logic and interface characteristics.

Memory IC Replacement Considerations

Check for direct substitutes within the 70T37xx series, such as the 70T3799MS133BBGI, noting differences in density and package availability. Verify pinout compatibility and electrical specifications before substituting. Some older IDT-branded equivalents may require verification of RoHS compliance and moisture sensitivity levels.
