7014S25PF

Memory IC Overview

The Renesas Electronics Corporation 7014S25PF is a dual-port, asynchronous SRAM memory IC with a total storage capacity of 36Kb. The memory organization is structured as 4K words by 9 bits. It features a parallel interface and operates within a supply voltage range of 4.5V to 5.5V. The device provides an access time of 25 ns and a write cycle time of 25 ns. It is housed in a 64-TQFP (14x14) surface-mount package and supports an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation for flexible system integration without clock synchronization requirements
• Parallel data interface supporting high-speed data transfer capabilities

Memory IC Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller-based designs
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the standard PF suffix may not meet current environmental regulations. Check for direct replacement availability such as the PFG variant before finalizing procurement plans. Ensure supply chain stability given discontinued manufacturing status.

Memory IC Selection Notes

Select this component when dual-port asynchronous SRAM functionality is required for 36Kb capacity needs. Consider the 25 ns access speed suitable for moderate-frequency parallel interfaces. Evaluate the 64-TQFP package constraints against PCB layout requirements. Compare against newer generation devices if lead times or environmental compliance are critical project factors.

Memory IC Part Context

The 7014S25PF belongs to the IDT 7014S series of dual-port SRAMs manufactured by Renesas Electronics. This series is designed for applications requiring independent port access. The part represents a legacy product line now classified as obsolete. Similar members include variants with different access speeds and packaging options within the same family.

Memory IC Replacement Considerations

The 7014S12PFG is listed as a direct substitute. Verify pin compatibility and electrical specifications before substitution. Note that the PFG suffix indicates potential differences in RoHS compliance compared to the original PF version.
