70T631S12BF

Memory IC Overview

The 70T631S12BF is a dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit organized as 256K x 18 bits. The device operates with an access time of 12 ns and utilizes a parallel interface. It supports a supply voltage range from 2.4 V to 2.6 V, with a maximum power supply current of 395 mA. The component is designed for surface-mount installation in a 208-CABGA package. It functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Provides independent read/write ports for simultaneous data access
• Supports asynchronous operation with fast 12 ns access speed
• Operates on standard 2.5 V power supply specifications

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data storage in industrial control networks

Memory IC Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for active obsolescence notices or product discontinuation alerts. Ensure the supplier provides valid traceability documents. Validate package dimensions against the specific CABGA-208 variant.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Compare against single-port alternatives if only one processor requires memory access. Verify that the 2.5 V operating voltage aligns with the system power rails. Consider the 208-CABGA package constraints for PCB layout and thermal management requirements.

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 70V631 and 70T633, differing primarily in voltage levels and organization. The series targets applications requiring high-bandwidth memory sharing between multiple controllers.

Memory IC Replacement Considerations

Check for direct substitutes such as IDT70T631S12BFI. Verify compatibility with 70T631S12BCI variants regarding package size.
