70T659S10BFI8

Memory IC Overview

The 70T659S10BFI8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The device features asynchronous parallel interfaces with a maximum access time of 10 ns. It operates within a supply voltage range of 2.4V to 2.6V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 208-lead CABGA package measuring 15x15 mm.

Memory IC Feature Summary

• Supports independent simultaneous read/write operations at both Port A and Port B without conflict.
• Features asynchronous operation allowing flexible timing control for each port independently.
• Includes collision detection logic to identify simultaneous write attempts on the same address.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data logging in industrial automation controllers

Memory IC Procurement Notes

Verify the specific suffix 'I8' against the official datasheet to confirm the tape and reel packaging configuration. Confirm RoHS compliance status as historical records indicate variations within this family. Check for End-of-Life notifications or Product Change Notices regarding label changes or material updates before finalizing procurement plans.

Memory IC Selection Notes

Select this component when independent dual-port access is required for high-bandwidth applications. Ensure the system design accommodates the 2.5V nominal supply voltage and the 208-CABGA footprint. Verify that the 10 ns access speed meets the timing requirements of the host processor interface.

Memory IC Part Context

This part belongs to the 70T659 series of dual-port SRAMs. It shares architectural similarities with other members like the 70V659 but differs in operating voltage and temperature rating. The 70T659 series is designed for applications requiring high reliability and fast data transfer rates between two independent masters.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the 70T659 family that match the voltage and temperature specifications. Verify if alternative packages are available from the manufacturer for updated manufacturing processes.
