70T631S10BCI8

Memory IC Overview

The 70T631S10BCI8 is a dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage organization of 256K x 18 bits, providing a total capacity of 4.5 Mbit. The device operates with a maximum access time of 10 ns and supports parallel interface communication. It functions within a supply voltage range of 2.4 V to 2.6 V. The component is housed in a 256-pin CABGA package measuring 17x17 mm. It is designed for asynchronous operation and supports an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.
• Asynchronous operation mode allowing flexible timing control without clock synchronization.
• Standard power consumption profile suitable for general-purpose embedded applications.

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in network infrastructure equipment
• Storage buffers in telecommunications base stations

Memory IC Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as sources indicate non-compliance. Check for end-of-life notifications or product discontinuance notices prior to procurement. Ensure supply chain availability aligns with project timelines due to potential legacy status.

Memory IC Selection Notes

Select this component when a 4.5 Mbit dual-port SRAM with 10 ns access speed is required. Ensure the design accommodates the 2.4 V to 2.6 V supply voltage range. Verify that the 256-pin CABGA footprint fits the PCB layout constraints. Consider thermal management requirements for the specified operating temperature range.

Memory IC Part Context

This part belongs to the 70T631 series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 70T631S12BCI8 but differs in access speed and packaging options. The series is designed for applications requiring high-bandwidth data transfer between two independent processors or systems.

Memory IC Replacement Considerations

The 70T631S12BCI8 is a similar variant with 12 ns access time. Verify pin compatibility and electrical specifications before substitution. No direct equivalent replacements are confirmed in public documentation.
