70T3589S166BF

Memory IC Overview

The Renesas Electronics 70T3589S166BF is a synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 2 Mbit organized as 64K x 36 bits. The component supports a maximum clock frequency of 166 MHz with a typical access time of 3.6 ns. It operates within a supply voltage range of 2.4 V to 2.6 V. The device utilizes a parallel interface and is housed in a 208-lead CABGA package measuring 15x15 mm. It is designed for high-speed data processing applications requiring simultaneous independent access.

Memory IC Feature Summary

• Supports true dual-port architecture allowing simultaneous access to the same memory location without conflict
• Features selectable pipelined or flow-through output modes for flexible system integration
• Includes on-chip collision detection, counters, and interrupt capabilities for advanced port management

Memory IC Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications systems utilizing synchronous data transfer protocols
• Industrial automation controllers needing reliable dual-processor communication

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific suffix indicates non-compliance. Check moisture sensitivity level handling procedures before assembly. Ensure design-in compatibility with existing 2.5V logic levels. Validate lead times with distributors as stock may be limited.

Memory IC Selection Notes

Select this component when synchronous dual-port SRAM with 36-bit width is required. Compare against 70V3589 series for 3.3V operation needs. Consider pinout compatibility if replacing older IDT variants. Verify thermal performance within the commercial temperature range. Assess power consumption against system budget constraints.

Memory IC Part Context

This part belongs to the 70T3589 family of high-speed synchronous dual-port SRAMs. It shares architectural similarities with other members like the 70T3519 and 70T3599. The family is characterized by low latency and high bandwidth capabilities. Renesas acquired the original IDT technology line, maintaining backward compatibility with previous generations.

Memory IC Replacement Considerations

Check for direct substitutes within the 70T3589 series such as different speed grades. Verify pin-to-pin compatibility with legacy IDT70T3589 parts. Evaluate alternative vendors offering similar 64Kx36 synchronous dual-port configurations.
