70T633S15BC8

Memory IC Overview

The Renesas 70T633S15BC8 is a dual-port asynchronous static random-access memory (SRAM) device featuring a total storage capacity of 9 Mbit. The memory architecture is organized as 512K words by 18 bits, providing independent read/write ports for simultaneous data access. It operates with a maximum access time of 15 ns and supports a core voltage range of 2.4 V to 2.6 V. The component utilizes a parallel interface and is housed in a 256-pin CABGA package measuring 17x17 mm. It is designed for standard power applications within an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation with fast 15 ns access time for high-speed data handling
• Integrated 18-bit bus width supporting wide data transfer requirements
• Standard power supply operation at 2.5V nominal voltage

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network processing systems
• Data storage in industrial control systems requiring rapid access
• Embedded memory solutions in automotive electronic control units

Memory IC Procurement Notes

Verify the specific suffix BC8 against the manufacturer's current datasheet to confirm pinout compatibility and moisture sensitivity level. Ensure the design accommodates the 256-pin CABGA package dimensions and thermal requirements. Confirm that the 2.5V power supply rails meet the specified tolerance limits for reliable operation across the full industrial temperature range.

Memory IC Selection Notes

Select this component when independent dual-port access is required for concurrent read and write operations without arbitration delays. The 15 ns speed class suits applications needing moderate latency with high bandwidth. Consider the 18-bit data width if interfacing with processors or FPGAs that support non-standard byte widths. Evaluate the CABGA package for board space constraints and soldering capabilities.

Memory IC Part Context

This part belongs to the Renesas 70T633 series of dual-port SRAMs. Variants in this family typically share the same 512K x 18 organization but differ in access speeds such as 10 ns, 12 ns, or 15 ns. The BC8 suffix denotes the specific package type and tape/reel packaging configuration. All variants maintain the same functional pinout and electrical characteristics except for timing parameters.

Memory IC Replacement Considerations

Compatible substitutes include other 70T633 series parts with identical 512K x 18 organization and CABGA-256 packaging. Verify that any replacement part meets or exceeds the 15 ns access time requirement. Ensure the alternative device supports the same 2.5V core voltage and operates within the -40°C to +85°C temperature range.
