70T659S10BC

Memory IC Overview

The 70T659S10BC is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The device features asynchronous parallel interfaces for both ports and supports a supply voltage range of 2.4V to 2.6V. It offers a maximum access time of 10 ns and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 256-lead CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access via two separate ports
• Asynchronous operation with fast 10 ns access times for high-speed data retrieval
• Industrial-grade reliability supporting extended temperature environments

Memory IC Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications systems utilizing parallel data processing
• Industrial control systems operating in harsh thermal conditions

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review official product change notifications for any labeling or specification updates issued during the end-of-life phase.

Memory IC Selection Notes

Select this component when dual independent port access is required for complex data routing tasks. Ensure system power supplies strictly maintain the 2.4V to 2.6V range to guarantee timing specifications. Validate PCB layout compatibility with the 256-lead CABGA footprint and thermal dissipation requirements.

Memory IC Part Context

This part belongs to the 70T659 series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 70T651 and 70T657 but differs in organization and pinout configurations. The series targets applications demanding high bandwidth and concurrent read/write operations across distinct memory banks.

Memory IC Replacement Considerations

Official substitutes include the 70T659S10DR and 70T659S10BCI. Verify pin compatibility and electrical characteristics before substitution.
