70T3589S200BC8

Memory IC Overview

The Renesas Electronics Corporation 70T3589S200BC8 is a high-speed synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 2 megabits organized as 64K words by 36 bits. The component supports a maximum clock frequency of 200 MHz with an access time of 3.0 nanoseconds. It operates on a single 2.5-volt power supply and utilizes a parallel interface. The device is housed in a 256-lead CABGA package measuring 17x17 millimeters, designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B without performance degradation
• Includes on-chip hardware arbitration logic to manage bus contention during simultaneous accesses
• Provides interrupt flag generation and semaphore signaling capabilities for inter-port communication
• Features fully asynchronous operation from either port while maintaining synchronous pipeline architecture

Memory IC Applications

• High-performance telecommunications systems requiring low-latency data buffering
• Network infrastructure equipment utilizing packet switching and routing
• Industrial automation controllers needing fast real-time data processing
• Embedded systems demanding reliable dual-port memory for multi-core architectures

Memory IC Procurement Notes

Verify the specific suffix BC8 against official Renesas documentation to confirm the exact package dimensions and pinout configuration. Ensure compatibility with 2.5V logic levels and check for lead-free status requirements. Confirm availability through authorized distributors as this series may have limited stock or end-of-life status. Validate moisture sensitivity level handling procedures prior to assembly.

Memory IC Selection Notes

Select this component when system design requires true dual-port capability with independent ports for concurrent data access. Consider the 200 MHz speed and 36-bit width for applications needing high bandwidth. Evaluate the 256-CABGA package size against board space constraints. Compare against lower-speed variants if power consumption is a critical factor, noting that higher frequencies generally increase dynamic power usage.
