70T3589S133BFI8

Memory IC Overview

The Renesas 70T3589S133BFI8 is a high-speed synchronous dual-port static random-access memory (SRAM) device. It features a storage organization of 64K words by 36 bits, providing a total capacity of 2 Mbit. The component supports an I/O clock frequency of up to 133 MHz with interleaved inputs and outputs. It operates on dual voltage supplies: a core voltage of 2.5V and I/O levels compatible with both 2.5V and 3.3V LVTTL standards. The device is housed in a 208-lead CABGA package measuring 15.0 x 15.0 mm.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct clocks
• Interleaved input/output configuration for optimized signal integrity at high speeds
• Integrated collision detection logic to manage concurrent write conflicts
• Supports multiple operational modes including sleep mode for power reduction

Memory IC Applications

• High-performance networking equipment requiring low-latency data buffering
• Telecommunications systems utilizing synchronous data transfer protocols
• Industrial automation controllers needing reliable dual-access memory resources
• Embedded systems demanding fast parallel interface connectivity

Memory IC Procurement Notes

Verify the specific suffix 'I8' indicates tape and reel packaging rather than tray distribution. Confirm RoHS compliance status as lead-free options may vary within this series. Check for moisture sensitivity level requirements during handling. Ensure voltage supply rails match the specified 2.5V core and 3.3V/2.5V I/O requirements before integration.

Memory IC Selection Notes

Select this component when dual-port functionality with interleaved I/O is required for 36-bit wide data paths. Compare against standard single-port variants if only one access port is needed. Consider the 208-CABGA package constraints for PCB layout. Verify that the 133 MHz clock speed meets the system timing requirements compared to slower alternatives in the 70V3589 series.

Memory IC Part Context

This part belongs to the 70T3589 family of synchronous dual-port SRAMs. It shares architectural similarities with the 70V3589 series but differs in pinout and electrical characteristics due to the interleaved I/O design. The 'T' designation typically denotes specific thermal or electrical variations within the broader Renesas memory portfolio.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with the 70V3589 series requires careful verification of pin compatibility and voltage levels.
