7007L25PF8

Memory IC Overview

The Renesas Electronics Corporation 7007L25PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a total storage capacity of 256K bits, organized as 32K words by 8 bits. The component features a parallel interface with both access time and write cycle time specified at 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports functional modes including busy, interrupt, master, semaphore, and slave operations. The device is housed in an 80-pin Thin Quad Flat Package (TQFP) with a 0.65mm pitch.

Memory IC Feature Summary

• Asynchronous dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Supports advanced communication protocols including busy flags, interrupts, semaphores, and master/slave configurations for coordinated data exchange
• High-speed parallel interface with 25ns access and write cycle times for rapid data throughput

Memory IC Applications

• Stand-alone 256K-bit dual-port RAM applications
• Master/Slave dual-port RAM combinations for multi-processor systems
• High-speed data buffering between asynchronous logic blocks

Memory IC Procurement Notes

Verify the exact package type and pinout compatibility before integration, as the 7007L25PF8 utilizes an 80-TQFP footprint. Confirm that the design supports the required 4.5V to 5.5V operating voltage range. Check for end-of-life status or alternative sourcing options, as availability may be limited. Ensure that the PCB layout accommodates the 0.65mm pitch to prevent soldering defects during assembly.

Memory IC Selection Notes

Select this component when independent read/write access from two separate masters is required without bus contention. The 25ns speed class suits applications demanding low-latency data sharing. Consider the 80-pin TQFP package if surface-mount technology is preferred over leaded packages. Evaluate the need for hardware-based synchronization features like semaphores and interrupts to simplify firmware complexity in multi-core environments.

Memory IC Part Context

The 7007L series represents Renesas' line of high-performance dual-port SRAMs. These devices are engineered for applications requiring fast, conflict-free data sharing between multiple processors. The 7007L25PF8 specifically offers a balance of density and speed, fitting into designs where traditional single-port memories would create bottlenecks due to arbitration delays.
