7007S20JI8

Memory IC Overview

The 7007S20JI8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 256 kilobits, organized as 32K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports commercial temperature conditions from 0°C to 70°C. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations at both Port A and Port B without bus contention
• Utilizes asynchronous logic control for flexible integration into various system timing architectures
• Employs standard parallel data interfaces compatible with legacy microprocessor and DSP systems

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in embedded network appliances

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as this specific part number is identified as non-compliant in official distributor records. Confirm current availability, as the product may be subject to discontinuation notices or limited supply constraints. Ensure that the 68-PLCC package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling between two independent masters. The 20ns speed class suits applications needing moderate latency without the complexity of synchronous clocking. Consider the PLCC package type if the design utilizes through-hole or specific surface-mount assembly processes compatible with leadless chip carriers rather than modern ball grid arrays.

Memory IC Part Context

This SRAM belongs to the 7007 series, a family of high-performance dual-port memories originally developed by Integrated Device Technology (IDT) and later acquired by Renesas Electronics. The series is characterized by its ability to eliminate bus arbitration overhead, making it suitable for complex multi-processor environments where deterministic access times are critical for system stability.
