7027S12G

Memory IC Overview

The Renesas Electronics Corporation 7027S12G is a high-speed, asynchronous dual-port static random access memory (SRAM) IC. It provides a total storage capacity of 512 kbit, organized as 32k words by 16 bits. The device features a parallel interface with a maximum access time of 12 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 108-pin PGA package measuring 30.48 x 30.48 mm. The component is designed for single data rate (SDR) applications.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems
• Asynchronous operation allowing flexible timing integration without external clock synchronization
• High-speed parallel interface supporting rapid data transfer rates for performance-critical applications

Memory IC Applications

• Stand-alone dual-port memory modules in embedded systems
• Data buffering between asynchronous communication interfaces
• Cache memory implementation in microprocessor-based designs

Memory IC Procurement Notes

Verify RoHS compliance status prior to procurement, as the specific variant may not meet current environmental directives. Confirm package integrity upon receipt, as PGA components require careful handling to prevent pin damage. Ensure the supplier provides valid traceability documentation. Check for obsolescence notices from Renesas Electronics Corporation before finalizing orders, as availability may be restricted.

Memory IC Selection Notes

Select this component when independent read/write access from two distinct masters is required. The 12 ns speed suits moderate-to-high frequency asynchronous buses. Verify that the 108-PGA footprint fits the target PCB layout constraints. Consider power consumption limits against the 4.5 V to 5.5 V operating range. Evaluate thermal dissipation requirements for the SMD/SMT installation style in the final enclosure design.

Memory IC Part Context

The 7027S12G belongs to the Renesas 7027S/L series of high-speed dual-port SRAMs. This family is engineered for applications requiring shared memory access without bus contention. The 'S' suffix typically denotes specific speed grades within the product line. These devices serve as reliable non-volatile-free storage solutions for temporary data holding in industrial and commercial electronic systems.

Memory IC Replacement Considerations

Direct substitutes include other members of the 7027S/L series with compatible pinouts and electrical characteristics. Verify that any replacement maintains the 32k x 16 organization and 12 ns access time. Ensure the alternative part supports the same 108-PGA package dimensions. Cross-reference datasheets to confirm identical control signal definitions and power supply requirements.
