Memory IC Overview

The 7140LA100PDG is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. 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 100 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in a 48-pin Dual In-line Package (DIP). The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

Data buffering in high-speed digital systems.

Memory IC Procurement Notes

This component has reached end-of-life status, with official discontinuation effective July 29, 2026. Verification of the specific manufacturer part number against current distributor catalogs is essential due to limited availability. Sourcing should focus on authorized channels or verified surplus suppliers to ensure authenticity and proper handling of obsolete inventory.

Memory IC Selection Notes

Designers requiring this specific memory configuration must account for its discontinued status when planning long-term production. Alternative solutions should be evaluated based on pin compatibility and functional equivalence, considering that direct replacements may require schematic modifications or board redesigns to accommodate different package types or electrical characteristics.

Memory IC Part Context

The 7140LA100PDG belongs to the 7140LA series of dual-port SRAMs from Renesas Electronics. This series is designed for applications requiring concurrent data access from two independent buses. The 'LA' suffix typically denotes specific speed grades and package variations within the broader product family, distinguishing it from other variants like the IDT7130SA/LA series.
