Memory IC Overview

The Renesas Electronics Corporation 7140SA55L48B is an asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features parallel interface access with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 48-lead Low Profile Plastic Quad Flat Package (LCC). The component is designed for industrial temperature ranges.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on two separate ports
Asynchronous operation allowing flexible timing control without external clock synchronization
CMOS technology providing high-speed data access with low power consumption characteristics

Memory IC Applications

High-performance embedded systems requiring concurrent data handling
Industrial automation controllers needing reliable volatile memory storage
Telecommunications equipment utilizing fast buffer memory capabilities

Memory IC Procurement Notes

Verify the specific suffix L48B to confirm the 48-LCC package variant, as other suffixes indicate different form factors. Confirm RoHS compliance status as older batches may differ. Check current lifecycle status as this series has faced discontinuation notices. Ensure compatibility with existing PCB footprints for 48-lead LCC packages before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for independent bus access. Compare against single-port alternatives if only one master device accesses the memory. Verify that the 55ns access speed meets system timing requirements. Consider the 48-LCC package constraints for surface-mount assembly processes and thermal management needs.

Memory IC Part Context

This part belongs to the 7140SA family of dual-port SRAMs from Renesas. It shares architectural similarities with the 7140SA55P but differs in packaging. The family is known for CMOS performance in industrial applications. Understanding the broader 7140SA series helps in identifying compatible pinouts and electrical characteristics across different package options.
