70T651S10BF8

Memory IC Overview

The 70T651S10BF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 megabits, organized as 256K words by 36 bits. The device features an asynchronous parallel interface with a maximum access time of 10 nanoseconds. It operates within a supply voltage range of 2.4V to 2.6V and supports surface-mount installation in a 208-lead CABGA package measuring 15x15 mm. The component is designed for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two separate ports
• Utilizes a common data bus architecture for both port interfaces
• Operates asynchronously without requiring a system clock signal

Memory IC Applications

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

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations exist between tape-and-reel and tray packaging formats. Confirm RoHS compliance status, as specific suffixes may indicate leaded or non-compliant variants. Check current production status, as this part number family has been subject to end-of-life notifications. Ensure compatibility with existing board layouts regarding the 208-CABGA footprint and moisture sensitivity level requirements during assembly.

Memory IC Selection Notes

Select this component when a high-density 9Mb dual-port SRAM with a 36-bit word width is required. The 10ns access speed suits applications needing rapid data throughput. Verify that the 2.5V nominal supply voltage aligns with the target system power rails. Consider the 208-CABGA package size constraints and thermal dissipation capabilities for the intended enclosure design.

Memory IC Part Context

This device belongs to the 70T651 series of dual-port SRAMs from Renesas. The series offers various access speeds and packaging options to accommodate different performance and form-factor requirements. The 70T651S10BF8 specifically targets applications requiring fast, reliable memory access with independent port control in a compact surface-mount package.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully before replacing.
