70T3399S133BC8

Memory IC Overview

The 70T3399S133BC8 is a synchronous dual-port SRAM manufactured by Renesas Electronics Corporation. It features a storage capacity of 2Mb organized as 128K x 18 bits. The device supports parallel interface operations with a maximum clock frequency of 133 MHz and an access time of 4.2 ns. It operates on a single power supply voltage ranging from 2.4V to 2.6V. The component is housed in a 256-CABGA package measuring 17x17 mm, designed for surface mount installation. It functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to memory locations by two separate processors or systems.
• Synchronous operation ensures data transfer is coordinated with a global clock signal for precise timing control.
• Parallel interface allows high-speed data transmission across multiple lines simultaneously.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part does not meet current standards. Validate package integrity upon receipt, as moisture sensitivity level 4 requires strict handling protocols. Check for obsolescence notices and ensure replacement strategies are in place for long-term production support.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure system voltage aligns with the 2.4V to 2.6V specification. Consider the 256-CABGA package constraints for PCB layout. Evaluate thermal management needs for the 0°C to 70°C operating range. Verify that the 133 MHz clock speed meets application latency requirements.

Memory IC Part Context

This part belongs to the 70T3399 series of synchronous dual-port RAMs. It shares architectural similarities with other variants in the family but differs in specific speed grades and packaging options. The series is designed for applications requiring high-bandwidth memory access between two independent masters.
