70T3589S166BC

Memory IC Overview

The 70T3589S166BC is a synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 2 Mbit organized as 64K 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 2.5V supply voltage within the range of 2.4V to 2.6V. The component is housed in a 208-CABGA package measuring 15x15 mm and is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports using true dual-port memory cells.
• Enables depth expansion without additional logic through full dual chip enable functionality.
• Offers selectable output modes, allowing configuration between pipelined or flow-through architectures.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in network processing equipment
• Data storage in industrial control applications requiring parallel interfaces

Memory IC Procurement Notes

Verify component authenticity due to discontinuation status. Confirm package integrity and moisture sensitivity handling prior to assembly. Check for RoHS compliance variations across production batches. Validate pin compatibility with existing PCB footprints. Review official product change notifications for any labeling or material updates.

Memory IC Selection Notes

Select this component for designs requiring high-bandwidth parallel data transfer with independent port access. Ensure power supply stability within the specified 2.4V to 2.6V range. Consider thermal management for commercial temperature environments. Verify interface voltage levels match system requirements. Evaluate alternative packages if lead-free compliance is mandatory.

Memory IC Part Context

This part belongs to the 70T3589 series of synchronous dual-port SRAMs. The series provides high-speed memory solutions with flexible I/O options. Variants exist for different speeds and voltage levels. The 70T3589S166BC specifically targets 166 MHz performance at 2.5V.
