70T3599S166DR

Memory IC Overview

The 70T3599S166DR is a synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.6 ns. It operates on a single 3.3V power supply, with voltage specifications ranging from 3.15V to 3.45V. The component utilizes a parallel interface and is housed in a 208-pin PQFP package designed for surface-mount technology.

Memory IC Feature Summary

• Provides simultaneous independent read/write access to two ports via a synchronous parallel interface.
• Integrates collision detection logic to manage concurrent access conflicts between the two ports.
• Supports standard single data rate (SDR) operation synchronized to a system clock signal.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data storage in industrial automation control systems

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates conflicting information regarding lead-free certification for this specific part number. Confirm current lifecycle status, as multiple sources list the component as discontinued or end-of-life. Ensure compatibility with existing PCB footprints and moisture sensitivity levels before procurement planning.

Memory IC Selection Notes

Select this component when a high-density 36-bit wide synchronous dual-port SRAM is required for 3.3V applications. Compare against the 70T3599S166BF8 variant if a BGA package is preferred over the PQFP form factor. Consider the 70V3599 series for alternative packaging options within the same functional family.

Memory IC Part Context

This device belongs to the 70T3599 series of high-speed synchronous dual-port SRAMs. It shares architectural similarities with other members like the 70V3599 and 70T3589, differing primarily in speed grade, voltage requirements, and physical package configuration. The series is designed for demanding embedded memory applications requiring low latency.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. The 70T3599S166BF8 offers identical electrical performance but utilizes a 208-CABGA package instead of PQFP. Verify pinout and thermal characteristics when considering alternative packages.
