7025S15PF8

Memory IC Overview

The Renesas Electronics Corporation 7025S15PF8 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 on a single 5V power supply with an access time of 15 nanoseconds and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent reads and writes
• On-chip hardware support for semaphore signaling between ports
• Automatic power-down feature controlled by Chip Enable signals
• TTL-compatible inputs and outputs for direct interface with logic systems

Memory IC Applications

• Master/Slave dual-port RAM configurations in 32-bit or wider data bus systems
• High-speed data buffering in telecommunications equipment
• Real-time signal processing applications requiring concurrent port access
• Industrial control systems operating within extended temperature environments

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 directives. Check for moisture sensitivity level 3 handling requirements during assembly. Ensure supply chain stability as this specific part number may be subject to discontinuation or long lead times.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. Choose based on the 15 nanosecond access speed requirement for high-throughput applications. Consider the 100-pin TQFP package constraints for PCB layout. Evaluate power consumption needs against the automatic power-down capabilities provided by the chip enable controls.

Memory IC Part Context

This component belongs to the Renesas 7025 series of dual-port SRAMs. The series offers various access speeds including 15, 20, 25, 35, and 55 nanoseconds. The 'S' suffix typically denotes industrial temperature range availability. The 'PF8' suffix indicates the specific package type and tape/reel packaging configuration for automated assembly processes.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 7025L20PFGI. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement supports the required industrial temperature range if applicable.
