7025S45PF8

Memory IC Overview

The Renesas 7025S45PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a density of 128K bits. It features an 8K x 16 organization and supports parallel interface operations. The device provides simultaneous independent access to memory locations from two separate ports. Key electrical specifications include a maximum access time of 45 nanoseconds and a supply voltage range of 4.5V to 5.5V. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous read/write operations from both ports without conflict.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage bus contention.
• Separate upper-byte and lower-byte control lines allow compatibility with multiplexed data buses.
• Automatic power-down mode controlled by Chip Enable signals to minimize standby power consumption.

Memory IC Applications

• High-performance computing systems requiring fast data exchange between processors.
• Network routers and switches utilizing master/slave dual-port configurations.
• Industrial automation controllers needing reliable real-time data buffering.
• Telecommunications equipment requiring low-latency signal processing memory.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for moisture sensitivity level handling requirements during storage and assembly. Ensure the specific suffix matches the required package and temperature grade. Validate lead times as availability may vary significantly across regions.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is critical for system performance. Consider the 45ns access speed against other variants in the 7025 series based on timing constraints. Evaluate the 100-pin TQFP footprint against available PCB space and routing complexity. Compare power consumption characteristics if battery backup or low-power modes are required for the application design.

Memory IC Part Context

The 7025 series represents Renesas' high-speed dual-port SRAM family designed for complex embedded applications. These devices bridge the gap between single-port memories and more complex FIFOs by offering true simultaneous access. The series supports various access speeds and packages to accommodate different system architectures and thermal requirements.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 7025L20PFGI. Verify pinout compatibility and electrical parameter alignment before substitution. Note that alternative parts may differ in package type or operating temperature range.
