Memory IC Overview

The Renesas Electronics Corporation 7140LA55CB is a dual-port static random access memory (SRAM) integrated circuit. It provides an 8-kilobit storage capacity organized as 1K words by 8 bits. The device utilizes a parallel interface with asynchronous operation and features a 55 nanosecond access time. It operates within a supply voltage range of 4.5V to 5.5V. The component is housed in a 48-pin ceramic dual in-line package (CDIP-SB-48).

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous access from two separate processors.
Asynchronous parallel interface for straightforward integration into legacy systems.
CMOS technology providing high-speed data transfer capabilities.

Memory IC Applications

High-performance embedded systems requiring concurrent data access.
Industrial control applications utilizing legacy parallel interfaces.
Telecommunications equipment requiring reliable volatile memory storage.

Memory IC Procurement Notes

Verify the specific suffix CB against official documentation to confirm the ceramic package variant, as standard plastic packages may use different suffixes. Confirm RoHS compliance status, as older ceramic variants often lack modern environmental certifications. Check for active discontinuation notices or end-of-life declarations prior to procurement planning.

Memory IC Selection Notes

Select this component when a design requires true dual-port functionality for independent master-slave or peer-to-peer memory sharing. Ensure the system supports parallel addressing and data buses. Verify that the 48-pin CDIP footprint matches the printed circuit board layout constraints and thermal requirements.

Memory IC Part Context

This part belongs to the 7140LA series of dual-port SRAMs manufactured by Renesas Electronics. The series typically includes variations in speed grades and packaging options. The LA designation generally indicates a specific pinout and electrical characteristic set distinct from other series members.
