7007L35PF8

Memory IC Overview

The 7007L35PF8 is a dual-port static random access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 256 kilobits organized as 32K words by 8 bits. The device operates with a parallel interface and supports asynchronous operation. Key electrical parameters include an access time of 35 nanoseconds and a write cycle time of 35 nanoseconds. It functions within a supply voltage range of 4.5V to 5.5V and maintains an operating temperature range from 0°C to 70°C. The component is housed in an 80-TQFP package.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports for high-throughput data handling.
• Includes on-chip hardware logic for semaphore signaling to manage port arbitration and prevent bus contention.
• Features automatic power-down control via Chip Enable signals to reduce standby power consumption during idle periods.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring fast concurrent access

Memory IC Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on existing stock or surplus markets rather than direct manufacturer orders. Confirm the specific suffix PF8 indicates the tape-and-reel packaging format when sourcing replacements, as this affects handling procedures. Ensure compatibility with RoHS standards if required by current assembly regulations.

Memory IC Selection Notes

Select this part for designs requiring true dual-port SRAM with 35ns speed and 8-bit width. Verify that the 80-pin TQFP footprint matches the PCB layout constraints. Consider the 5V supply requirement and industrial temperature limits. Evaluate alternative packages like PLCC-68 if pin count differs, but ensure functional equivalence for the 256Kb density.

Memory IC Part Context

The 7007L35 series belongs to Renesas' legacy line of high-speed dual-port SRAMs designed for complex system interconnects. These devices facilitate communication between processors without external arbitration logic. The 7007L35PF8 specifically denotes the 35ns speed grade in the 80-pin TQFP reel package, serving as a critical memory node in multi-master architectures.

Memory IC Replacement Considerations

Verify cross-reference with IDT7007L35PF8 for functional equivalence. Check for updated package options such as LQFP variants if lead-free compliance is mandatory. Confirm that any substitute maintains the same 32Kx8 organization and 35ns access time specifications.
