70T633S12BFGI

Memory IC Overview

The 70T633S12BFGI is a 9 Mbit (512K x 18) asynchronous dual-port static RAM manufactured by Renesas Electronics. It operates on a single 2.5V power supply with a maximum voltage of 2.6V and a minimum of 2.4V. The device features a parallel interface with a 12 ns access time. It is housed in a 208-CABGA package measuring 15x15 mm, suitable for surface mount installation. The component supports an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to memory locations from two separate ports.
• Asynchronous operation allows flexible timing control without requiring a system clock signal.
• Single 2.5V core power supply reduces overall system power consumption requirements.
• Integrated hardware support for semaphore signaling facilitates data synchronization between ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers
• Network switch buffer memory applications

Memory IC Procurement Notes

Verify the specific suffix BFGI to confirm the 208-CABGA package type and tape-and-reel shipping configuration. Confirm RoHS compliance status as documentation indicates varying classifications across similar part numbers. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure the supplier provides valid traceability documents for the manufacturing origin.

Memory IC Selection Notes

Select this component when a 512K x 18 organization is required for dual-port memory applications. The 12 ns access time suits moderate-speed asynchronous interfaces. Verify that the system design accommodates the 2.5V core voltage and LVTTL-compatible I/O levels. Consider the 208-CABGA footprint constraints during PCB layout planning.

Memory IC Part Context

This part belongs to the 70T633 series of high-speed dual-port SRAMs. It shares architectural similarities with other members like the 70T633S12BFI but differs in packaging and shipping format. The series is designed for applications requiring concurrent read/write operations without external arbitration logic.

Memory IC Replacement Considerations

IDT70T633S12BFGI is listed as an alias for this component. Verify pinout compatibility before substitution. Other series members like 70T633S12BCI offer different package options but require mechanical redesign.
