7008L55G

Memory IC Overview

The Renesas Electronics Corporation 7008L55G is a dual-port static random-access memory (SRAM) IC with a total density of 512Kbits. The device features an architecture organized as 64K words by 8 bits, providing independent read/write access to two ports. It operates with a maximum access time of 55 nanoseconds and requires a core voltage supply of 5 volts. The component is housed in an 84-pin Plastic Grid Array (PGA) package measuring 27.94x27.94 mm. Key functional capabilities include busy signals, interrupts, and support for master/slave semaphore operations.

Memory IC Feature Summary

• Dual-port asynchronous architecture enabling simultaneous independent access
• Integrated hardware support for synchronization via semaphores
• Built-in interrupt and busy signal generation for status monitoring

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Real-time processing in industrial automation controllers
• Network equipment requiring low-latency memory access

Memory IC Procurement Notes

Verify the specific package variant, as the 7008L55G designation may correspond to different physical footprints such as PGA or TQFP depending on the manufacturer's suffix conventions. Confirm moisture sensitivity level and RoHS compliance status directly with the supplier, as these attributes can vary between production batches and regional specifications. Ensure the ordering part number matches the required pin count and thermal characteristics for your PCB design.

Memory IC Selection Notes

Select this component when a system requires true simultaneous bidirectional data access without bus contention. The 55 ns access speed suits applications needing moderate-to-high throughput. Consider the 84-pin PGA package constraints regarding board space and soldering requirements. Evaluate if the integrated semaphore logic simplifies your controller design compared to software-based locking mechanisms.

Memory IC Part Context

This part belongs to the 7008L series of dual-port SRAMs from Renesas. These devices are designed for applications demanding high reliability and fast data transfer rates. The series typically offers various access times and package options to fit different performance and form-factor requirements in embedded systems.

Memory IC Replacement Considerations

Check for direct cross-references from IDT or other memory manufacturers. Verify pin compatibility and electrical parameters before substitution. Note that some variants may have different packaging or lead-free statuses.
