70T3589S133BC8

Memory IC Overview

The Renesas Electronics 70T3589S133BC8 is a synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 2 Mbit organized as 64K words by 36 bits. The component supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates on a single 2.5V power supply, ranging from 2.4V to 2.6V. The device utilizes a parallel interface and is housed in a 256-CABGA package measuring 17x17 mm. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations at both ports without bus contention
• Integrates hardware semaphore signaling for port arbitration and collision detection
• Features interleaved I/O architecture to optimize data throughput efficiency

Memory IC Applications

• High-speed networking equipment requiring low-latency packet buffering
• Telecommunications systems utilizing multiplexed bus architectures
• Industrial control systems needing reliable dual-port data exchange

Memory IC Procurement Notes

Verify the specific suffix BC8 against current manufacturer documentation to confirm pinout compatibility and moisture sensitivity level requirements. Confirm RoHS compliance status as legacy listings may vary. Check for active production status or end-of-life notifications prior to finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 36-bit data width is required for synchronous applications. Ensure the design accommodates the 2.5V core voltage specification rather than standard 3.3V logic levels. Verify that the 256-pin CABGA package fits the available PCB real estate and thermal constraints.

Memory IC Part Context

This part belongs to the 70T3589 series of high-speed synchronous dual-port SRAMs. It is designed for applications demanding full-speed operation from either port. The series typically includes variants with different voltage ratings and package options to suit diverse system integration needs.

Memory IC Replacement Considerations

Cross-reference with IDT70T3589S133BC8 for potential functional equivalence. Verify pin-to-pin compatibility and electrical specifications before substitution.
