70T651S10BC8

Memory IC Overview

The 70T651S10BC8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features an asynchronous parallel interface with a total storage capacity of 9 megabits, organized as 256K words by 36 bits. The device supports a supply voltage range of 2.4V to 2.6V and offers a maximum access time of 10 nanoseconds. It is housed in a 256-pin CABGA package measuring 17x17 mm and operates within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data storage in industrial control applications

Memory IC Procurement Notes

This component has been officially discontinued by the manufacturer. Verification of availability should focus on authorized distributors offering remaining stock or approved replacement alternatives. Ensure that any substitute parts maintain compatibility with the original 256-CABGA footprint and electrical specifications.

Memory IC Selection Notes

Designers requiring this specific memory configuration must account for the end-of-life status when planning long-term production. Selection criteria should prioritize verifying the pinout compatibility and voltage levels of potential replacement devices from the same product family to ensure seamless integration into existing hardware designs.

Memory IC Part Context

The 70T651S10BC8 belongs to the 70T651 series of high-performance dual-port SRAMs. This series was originally developed by Integrated Device Technology (IDT) before being acquired by Renesas Electronics. The part represents a standard power variant designed for general-purpose high-speed memory applications requiring reliable data retention and fast access times.

Memory IC Replacement Considerations

Officially documented similar replacements include the 70T651S12BFI and 70T651S10BFGI8. These alternatives share the same 9Mb capacity and 256K x 36 organization but may differ in package type or operating temperature range.
