7025L17PF8

Memory IC Overview

The Renesas Electronics Corporation 7025L17PF8 is a high-speed asynchronous dual-port static random-access memory (SRAM) with a total storage capacity of 128 kilobits. The memory architecture is organized as 8K words by 16 bits, providing independent data buses for two distinct ports. This component features a 17 nanosecond access time and operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. The device supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory cells allow simultaneous independent reads and writes to the same memory location without conflict.
• Integrated hardware semaphore signaling logic facilitates automatic port arbitration and synchronization between the two ports.
• Separate upper-byte and lower-byte control lines enable compatibility with multiplexed bus systems.
• Automatic power-down mode controlled by Chip Enable signals reduces standby power consumption significantly.

Memory IC Applications

• Stand-alone 128K-bit dual-port RAM modules
• Master/Slave dual-port configurations for 32-bit or wider data systems
• High-speed data buffering in telecommunications equipment
• Real-time signal processing applications requiring concurrent data access

Memory IC Procurement Notes

Verify the specific suffix requirements against current Renesas documentation, as package and environmental specifications may vary. Confirm RoHS compliance status prior to integration, as older variants may not meet current regulations. Check for active obsolescence notices or end-of-life declarations. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. The 17ns speed suits moderate-to-high frequency asynchronous interfaces. Verify that the 100-pin TQFP footprint fits the target PCB layout. Consider the 5V supply requirement and ensure voltage levels match the system design constraints.

Memory IC Part Context

The 7025 series represents a family of high-performance dual-port SRAMs designed for complex embedded systems. These devices bridge the gap between standard single-port memories and more complex FIFO buffers. The 7025L17 variant specifically targets applications needing reliable, fast, and concurrent data handling capabilities in industrial and commercial environments.
