70T3599S133BC

Memory IC Overview

The Renesas Electronics Corporation 70T3599S133BC is a high-performance synchronous dual-port static random-access memory (SRAM) device. It provides a total storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The component supports a maximum clock frequency of 133 MHz and features a typical access time of 4.2 ns. It utilizes a parallel interface and is housed in a 256-pin CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in network processors
• Data acquisition systems requiring concurrent read/write operations

Memory IC Procurement Notes

Verify current lifecycle status before procurement, as this component is scheduled for obsolescence. Confirm package compatibility with existing PCB footprints. Ensure supply chain sources provide authentic Renesas Electronics products to avoid counterfeit risks. Check for specific ordering suffixes that may indicate environmental compliance or tape-and-reel packaging variations.

Memory IC Selection Notes

Select this component when synchronous dual-port functionality with 36-bit word width is required. Compare against single-port alternatives if concurrent access is unnecessary. Verify voltage level compatibility with system logic. Consider end-of-life status when planning long-term production cycles.

Memory IC Part Context

This part belongs to the 70T3599S133 family of synchronous dual-port SRAMs. It shares architectural similarities with other members like the 70V3599S133 series but differs in operating voltage specifications. The CABGA-256 package is common across several high-density memory devices in the Renesas portfolio.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the scheduled obsolescence, alternative sourcing should focus on verifying compatible pin-to-pin replacements through official manufacturer cross-reference tools.
