7008L15PF

Memory IC Overview

The Renesas Electronics Corporation 7008L15PF is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 15 nanoseconds. It operates on a single 5V power supply ranging from 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. It supports surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems without external arbitration logic.
• Asynchronous operation allows flexible timing control for each port, supporting variable clock rates and burst modes.
• Integrated hardware semaphore signaling facilitates efficient data exchange and synchronization between the two ports.
• Automatic power-down mode controlled by chip enable inputs reduces standby power consumption during inactive periods.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency packet handling.
• Cache memory implementation in embedded systems and industrial controllers needing rapid read/write cycles.
• Data logging applications where real-time capture from multiple sources into a shared memory space is required.
• Network switch fabric architectures utilizing dual-port RAM for traffic management and queueing.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as this specific part may not meet current environmental standards. Check for moisture sensitivity level handling procedures during storage and assembly. Ensure replacement parts are sourced from verified suppliers to avoid counterfeit components affecting system reliability.

Memory IC Selection Notes

Select this component when dual independent access to 512Kb of memory is necessary at 15ns speeds. Consider the 100-TQFP package constraints for PCB layout and thermal management. Evaluate power supply stability within the 4.5V to 5.5V range for consistent performance. Assess if asynchronous timing meets system latency requirements compared to synchronous alternatives.
