70T3339S133BF

Memory IC Overview

The Renesas Electronics 70T3339S133BF is a 9Mb synchronous dual-port static random access memory (SRAM) organized as 512K x 18. It operates at a maximum clock frequency of 133 MHz with an access time of 4.2 ns. The device utilizes a parallel interface and requires a supply voltage between 2.4V and 2.6V. It is housed in a 208-CABGA package measuring 15x15 mm, suitable for surface mount installation within an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports
• Features full synchronous operation on both ports for high-speed data transfer
• Includes JTAG functionality for boundary scan testing and system diagnostics

Memory IC Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications systems utilizing parallel data processing
• Industrial control systems needing reliable dual-port memory solutions

Memory IC Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Availability is restricted to existing stock or surplus channels only. Buyers must verify the authenticity of the source and check for moisture sensitivity level compliance before procurement. No new production units are available directly from Renesas Electronics.

Memory IC Selection Notes

Engineers should evaluate alternative components from the same family or newer generations due to the discontinuation status. Verify that the replacement supports the required 133 MHz clock speed and 208-pin CABGA footprint. Ensure the substitute part maintains compatibility with the 2.4V to 2.6V power supply requirements and industrial temperature specifications.

Memory IC Part Context

The 70T3339S133BF belongs to the 70T3339 series of synchronous dual-port SRAMs designed for high-throughput applications. This series emphasizes performance through synchronized clocking and flexible I/O configurations. The specific BF suffix indicates a tray packaging format and standard commercial temperature range operation within the broader product line.

Memory IC Replacement Considerations

IDT70T3339S133BF is a verified equivalent part number representing the same device under the Integrated Device Technology branding prior to acquisition.
