7008L20JI

Memory IC Overview

The Renesas Electronics Corporation 7008L20JI 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 of 20 nanoseconds. It operates on a single 5-volt supply voltage within the range of 4.5 to 5.5 volts. The component is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It supports surface-mount installation and functions across an industrial temperature range from -40°C to +85°C ambient temperature.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations for both ports
• Asynchronous operation eliminating the need for external clock synchronization signals
• Single 5V power supply requirement simplifying system power design
• Industrial-grade temperature rating suitable for demanding environmental conditions

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring rapid temporary storage

Memory IC Procurement Notes

Verify authenticity through authorized Renesas distributors due to end-of-life status. Confirm RoHS3 compliance for current production batches. Check moisture sensitivity level handling requirements during assembly. Validate package marking against official datasheet specifications. Ensure supplier provides traceability documentation for critical applications.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access. Compare access times against system timing constraints. Verify voltage compatibility with existing 5V logic levels. Consider package availability and footprint constraints for PCB layout. Evaluate thermal performance within the specified operating temperature range.

Memory IC Part Context

This part belongs to the IDT 7008L series of dual-port SRAMs. The series offers various access speeds and package options. Renesas acquired Intersil's memory product line, continuing support for these legacy components. The 7008L20 variant specifically denotes the 20ns speed grade within the family.

Memory IC Replacement Considerations

Official substitutes include other 7008L series variants with different access times or packages. Cross-reference pinouts before substitution. Verify electrical characteristics match original design requirements. Consult Renesas for recommended migration paths if discontinuation impacts production.
