Radiation Tolerant SPI NOR Flash: Latch-up Immune Space Qualified Memory

At 3D PLUS, we specialize in providing top-tier space qualified memory solutions designed to meet the rigorous demands of space applications. Our radiation tolerant SPI NOR Flash memories are engineered to deliver outstanding performance and high resistance in the harshest environments.

Product Line Overview

Our radiation tolerant SPI NOR Flash memories are latch-up immune and operate at 3.3 V, featuring a small pin count and a serial interface. These memories are designed with no bad blocks, high endurance, and long-term data retention, ensuring reliable performance over extended periods. Packaged in SOP for high resistance Surface Mount (SMT) assembly, our memories are built to withstand harsh thermal and mechanical conditions, making them ideal for space missions.

Our product line is divided into two sub-families to respond to different needs:

QSPI Modules: These modules offer high density and high speed, operating at up to 133 MHz. They are perfect for applications requiring fast data transfer and large storage capacities.

TMR Modules: These modules provide SEU immunity through triple modular redundancy and better TID tolerance via an integrated switch. They are designed for applications where data integrity and radiation tolerance are critical.

 

Proven Performance in Space Missions

First released in 2018, our 3D PLUS SPI NOR Flash memories have been successfully used as configuration memory for SRAM-based FPGAs and as boot/program memory for leading processors. These memory modules have been deployed in missions such as EMIT, SEACOM and others, demonstrating their reliability and high resistance in demanding space environments.

Why Choose 3D PLUS Space Qualified Memory?

Radiation Tolerant: Designed to withstand the radiation levels encountered in space.

High Resistance: Built to endure harsh thermal and mechanical conditions.

Reliable Performance: Proven track record in space missions, ensuring data integrity and longevity.
