70T3519S133BCI

Memory IC Overview

The Renesas 70T3519S133BCI is a synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The component supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates on a single 2.5V power supply, with a maximum voltage rating of 2.6V. The device utilizes a parallel interface and is housed in a 256-CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in network infrastructure equipment.

Memory IC Procurement Notes

Verify the specific suffix 'BCI' against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Ensure that the 2.5V operating voltage aligns with the target system design requirements before procurement. Confirm availability status directly with authorized distributors or the manufacturer, as lead times may vary for this specific package configuration.

Memory IC Selection Notes

Select this component when a high-density 9 Mbit synchronous dual-port SRAM is required for applications needing 133 MHz operation. The 256K x 36 bit organization suits systems requiring wide data buses. Verify that the 2.5V supply voltage matches the system's power rails and that the CABGA-256 package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the Renesas 70T3519 series of synchronous dual-port SRAMs. These devices are designed for high-performance embedded applications requiring fast data access and independent port control. The series typically offers various speed grades and packaging options to accommodate different system integration needs within industrial and communication sectors.

Memory IC Replacement Considerations

Check for direct substitutes such as the 70T3519S166BCI for higher speed requirements, ensuring pin compatibility and voltage levels match. Verify if alternative packages like FPBGA-208 variants are suitable for the specific board design without requiring schematic changes.
