Memory IC Overview

The Renesas Electronics Corporation 7140SA20J is an asynchronous dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface mount installation in a 52-pin Plastic Leadless Chip Carrier package.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous access from two separate systems
Asynchronous operation for flexible integration into various digital logic designs
CMOS technology construction ensuring low power consumption during standby and active states

Memory IC Applications

Data buffering between high-speed processors and slower peripheral devices
Cache memory implementation in embedded control systems
Temporary data storage in telecommunications equipment interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards as the part may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC footprint specifications before assembly.

Memory IC Selection Notes

Select this component when dual independent port access is required for 8-kilobit memory applications. Ensure the design accommodates the 52-PLCC surface mount package dimensions. Verify that the system logic levels align with the specified 4.5V to 5.5V operating voltage range for reliable signal interfacing.

Memory IC Part Context

This device belongs to the 7140SA series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a legacy component within the company's memory portfolio, previously distributed under IDT branding.
