70T3339S133BFI8

Memory IC Overview

The 70T3339S133BFI8 is a synchronous dual-port SRAM manufactured by Renesas Electronics Corporation. It features a 9 Mbit storage capacity organized as 512K 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 within a supply voltage range of 2.4V to 2.6V and functions in temperatures from -40°C to +85°C. The component is housed in a 208-CABGA package measuring 15x15 mm.

Memory IC Feature Summary

• Supports simultaneous independent access to memory locations via dual ports
• Features full synchronous operation for high-speed data transfer
• Includes collision detection and interrupt capabilities for port arbitration

Memory IC Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications systems utilizing burst data processing
• Industrial control systems demanding reliable dual-processor communication

Memory IC Procurement Notes

Verify the specific suffix BFI8 against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the 70T3339 family. Confirm current availability status directly with authorized distributors, as this component may be subject to discontinuation or limited stock conditions. Ensure compliance with RoHS3 standards and check moisture sensitivity levels prior to soldering.

Memory IC Selection Notes

Select this component when a 9 Mbit synchronous dual-port architecture is required for applications needing simultaneous read/write access. Compare against the 70T3519 series if a 256K x 36 organization is needed instead of 512K x 18. Ensure the system design accommodates the 2.4V to 2.6V core voltage requirement and the 208-pin CABGA footprint constraints.

Memory IC Part Context

This part belongs to the Renesas 70T3339 family of high-speed synchronous dual-port RAMs. These devices are designed for applications requiring unidirectional or bidirectional data flow in bursts. The family typically includes variants with different organizations and I/O voltages, such as the 70T3319 and 70T3519, sharing similar synchronous timing characteristics.
