7025L20PF8

Memory IC Overview

The Renesas Electronics Corporation 7025L20PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 128 kbit, organized as 8K words by 16 bits per word. The component features a parallel interface with a maximum access time of 20 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The device supports simultaneous independent access from two ports and includes hardware support for semaphore signaling and interrupt flags. It is housed in a 100-pin Thin Quad Flat Package (TQFP) suitable for surface mount technology.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous read/write operations from separate ports without conflict
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity
• Separate upper-byte and lower-byte control lines allowing compatibility with multiplexed bus systems
• Automatic power-down feature controlled by Chip Enable signals to minimize standby power consumption

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'PF8' against official manufacturer documentation to confirm package type and moisture sensitivity level. Ensure compliance with RoHS directives relevant to your region. Confirm availability status as distribution channels may list obsolete or end-of-life variants. Validate that the 100-pin TQFP footprint matches your PCB design requirements before ordering.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. It is suitable for applications needing fast data transfer between processors or peripherals. Consider the 20 ns access speed and 5V operating voltage. Evaluate the 100-pin TQFP package constraints against board space limitations. Compare against other speeds in the 7025 series if timing requirements differ.
