7025S15PFI8

Memory IC Overview

The Renesas Electronics Corporation 7025S15PFI8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device features independent read/write ports allowing simultaneous access to the same memory location without conflict. It operates with a maximum access time of 15 nanoseconds and supports a single 5V power supply within a range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm, designed for surface-mount installation.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent reads and writes from either port
• On-chip hardware support for semaphore signaling and automatic port arbitration logic
• Separate upper-byte and lower-byte control lines facilitating multiplexed bus compatibility
• Automatic power-down mode controlled by Chip Enable signals for low standby power consumption

Memory IC Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/Slave dual-port RAM configurations for 32-bit or wider data bus expansion
• High-speed data buffering in industrial control applications
• Real-time signal processing interfaces requiring concurrent port access

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package marking matches the 100-TQFP specification. Check for RoHS compliance variations across manufacturing lots. Validate replacement part numbers such as the 7025L series if active sourcing is required. Ensure storage conditions respect moisture sensitivity level 3 requirements.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required between two processors or controllers. The 15ns speed grade suits high-frequency asynchronous interfaces. Verify voltage tolerance aligns with the 4.5V to 5.5V operating range. Consider the 100-pin TQFP footprint for PCB layout constraints. Evaluate thermal performance within the specified -40°C to +85°C ambient temperature range.

Memory IC Part Context

The 7025S15PFI8 belongs to the Renesas 7025 family of high-speed dual-port SRAMs. This family offers various access times and packaging options to support diverse system architectures. The S-series denotes specific speed grades and package types within the broader product line. These devices are engineered for applications demanding high throughput and low latency data sharing between multiple masters.

Memory IC Replacement Considerations

The 7025L20PFGI is listed as a similar replacement option. Verify pin compatibility and electrical specifications before substitution. Note that the L-series may differ in speed grade or package variant. Confirm availability and lead times for the substitute component.
