70T3519S133BCI8

Memory IC Overview

The 70T3519S133BCI8 is a synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The device 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 voltage range of 2.4V to 2.6V. The component is housed in a 256-pin CABGA package measuring 17x17 mm and is rated for an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports independent read/write operations at two ports simultaneously
• Includes collision detection logic to manage simultaneous access conflicts
• Integrates JTAG interface for boundary scan testing and configuration

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network processing systems
• Data storage in industrial control applications requiring dual-port access

Memory IC Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm it denotes the tape and reel packaging format rather than a functional variation. Ensure compatibility with RoHS directives if required, as this specific part may not meet current environmental standards. Confirm lead times and availability directly with authorized distributors due to potential production lifecycle changes.

Memory IC Selection Notes

Select this component when a high-density 9 Mbit synchronous dual-port SRAM is required for parallel interfaces. It is suitable for designs needing 133 MHz operation with 2.5V logic levels. Consider the 256-CABGA package constraints for PCB layout. Verify that the 36-bit word width aligns with system bus requirements before finalizing the design.

Memory IC Part Context

This part belongs to the 70T3519 family of synchronous dual-port SRAMs from Renesas. These devices are designed for applications requiring high bandwidth and low latency. The family typically shares similar architectural features but varies in density and speed grades. The 70T3519 represents a specific configuration within this series optimized for 2.5V operation.

Memory IC Replacement Considerations

Check for direct substitutes such as the 70T3519S166BCI for higher speed requirements or other variants in the 70T3519 series. Verify pinout and electrical specifications match exactly before substitution.
