70T3589S133BFI

Memory IC Overview

The 70T3589S133BFI 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 133 MHz with an access time of 4.2 ns. It operates on a single 3.3V power supply within a voltage range of 3.15V to 3.45V. The component utilizes a parallel interface and is housed in a 208-lead CABGA package measuring 15x15 mm. It is rated for commercial operating temperatures from 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations at both Port A and Port B without conflict.
• Integrates collision detection logic to identify and manage simultaneous access attempts to the same address.
• Includes built-in counters for tracking access patterns and interrupt generation capabilities.
• Features JTAG interface support for boundary scan testing and device identification.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data logging in industrial control systems
• Real-time processing buffers in embedded computing platforms

Memory IC Procurement Notes

Verify the specific suffix 'BF' confirms the CABGA package type and lead configuration required for your PCB layout. Confirm RoHS compliance status, as this part may not meet current environmental directives depending on manufacturing date. Check moisture sensitivity level requirements for reflow soldering profiles. Ensure the 3.3V supply voltage matches your system design constraints before ordering.

Memory IC Selection Notes

Select this component when a synchronous dual-port architecture with 36-bit word width is required. It is suitable for applications needing high throughput at 133 MHz. Compare against the 70V3589 series if lower power consumption or different voltage levels are needed. Consider the 70T3589S166 variant if higher clock speeds up to 166 MHz are necessary for your performance targets.

Memory IC Part Context

This part belongs to the 70T3589 family of high-speed synchronous dual-port SRAMs. The 'T' designation typically indicates temperature range or specific process variations compared to the 'V' series. These devices are designed for demanding applications requiring fast data transfer rates and reliable concurrent access. The family shares common functional blocks but varies in speed grades and packaging options.

Memory IC Replacement Considerations

The IDT70T3589S133BFI is a direct equivalent part number from Integrated Device Technology, which was acquired by Renesas. Verify pin compatibility and electrical specifications match exactly. No other cross-manufacturer substitutes are confirmed in public documentation.
