7008L20PFI8

Memory IC Overview

The Renesas Electronics Corporation 7008L20PFI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 20 nanoseconds. It operates on a single 5V power supply within the voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. It supports industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems without bus contention.
• Fully asynchronous operation allows flexible timing control for both read and write cycles from either port.
• On-chip hardware support for semaphore signaling facilitates efficient data synchronization between ports.
• Automatic power-down feature controlled by chip enable signals reduces standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring rapid temporary storage
• Industrial control networks with multiple processor interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package marking and date codes against official Renesas documentation. Ensure RoHS3 compliance matches specific project requirements. Validate pin compatibility if replacing existing designs. Check for moisture sensitivity level handling precautions during assembly.

Memory IC Selection Notes

Select this component when dual-port isolation is required for concurrent data access. Consider the 20ns speed for moderate latency applications. Evaluate the 100-pin TQFP footprint against available board space. Assess power budget constraints given the 5V supply requirement. Compare against newer generations for long-term availability needs.

Memory IC Part Context

This part belongs to the IDT 7008L series of dual-port SRAMs. It shares architectural similarities with other members like the 7008L20PFGI8 but differs in packaging and lead-free specifications. The series is designed for high-reliability applications requiring robust inter-processor communication capabilities.

Memory IC Replacement Considerations

Official substitutes include IDT7008L20PFGI8 and IDT7008L20PF. Verify pinout compatibility before substitution. Check voltage tolerance ranges to ensure system stability. Confirm package dimensions match existing PCB footprints.
