70T3519S133BFGI

Memory IC Overview

The Renesas Electronics Corporation 70T3519S133BFGI 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 parallel interface and requires a supply voltage range of 2.4V to 2.6V. The device is housed in a 208-CABGA package measuring 15x15 mm.

Memory IC Feature Summary

• Provides simultaneous independent read/write access through two separate ports for high-throughput data handling.
• Integrates hardware semaphore signaling and port arbitration logic to manage bus conflicts without external components.
• Supports multiplexed bus compatibility via separate upper-byte and lower-byte control signals.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix BFGI against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status, as some variants may differ. Check current production lifecycle status, as this series has faced end-of-life notifications. Ensure design-in compatibility with 2.5V I/O levels before procurement.

Memory IC Selection Notes

Select this component when a system requires true dual-port architecture with hardware-based arbitration. It is suitable for applications needing 36-bit wide data paths at 133 MHz speeds. Compare against the 70T3319S133BFGI if a 18-bit width is sufficient, or the 70T3519S200BC8 for higher speed requirements in a different package.

Memory IC Part Context

This part belongs to the 70T3519 family of synchronous dual-port SRAMs from Renesas. These devices are designed for complex digital signal processing and communication applications. The family offers various speed grades and package options to fit different board space and performance constraints.

Memory IC Replacement Considerations

Check for direct substitutes within the 70T3519 series such as the 70T3519S133BC8. Verify pinout and electrical specifications match exactly. Consider the 70T3319S133BFGI if the 18-bit organization is acceptable for the application.
