7025S17PF8

Memory IC Overview

The Renesas Electronics Corporation 7025S17PF8 is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kbit, organized as 8K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 17 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a TQFP-64 package. The component is designed for commercial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation compatible with standard parallel bus interfaces
• Single data rate (SDR) memory technology for straightforward control logic

Memory IC Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller-based designs
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability should focus on surplus distributors or secondary markets rather than direct procurement from the manufacturer. Buyers must confirm the authenticity of the source and check for potential moisture sensitivity issues due to age. Compliance with current environmental regulations such as RoHS may not apply as the part predates these standards.

Memory IC Selection Notes

Engineers selecting this part should consider its discontinuation status when designing new products. The 17 ns access time and 64 kbit capacity define its performance envelope. Alternative components with similar pinouts or electrical characteristics should be evaluated for long-term supply stability. Designers must account for the specific 4.5 V to 5.5 V operating voltage requirements during system power planning.

Memory IC Part Context

The 7025S series represents Renesas' line of high-performance dual-port SRAMs. These devices are engineered for applications requiring concurrent read/write operations from two distinct masters. The PF8 suffix typically denotes specific packaging and lead finish options within the product family. This series bridges the gap between fast processor speeds and slower external memory solutions.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for the 7025S17PF8 were not identified in available documentation. Users should consult Renesas technical support for qualified replacements or evaluate generic dual-port SRAMs with matching 8Kx8 organization and 17 ns speed grades.
