Micron begins sampling highest capacity microSD card

21 June 2022

Micron Technology Inc. is now sampling what it claims is the world’s highest capacity microSD card designed with the world’s first 176-layer 3D NAND technology.

The i400 microSD is designed for industrial-grade video security. Micron is looking at the video security-as-a-service (VSaas) market that is estimated to be worth about $83 billion by 2030.

This includes fleet dash cameras, smart home security, police body cameras and artificial intelligence-enabled cameras in factories.

The 1.5TB density microSD card can store up to four months of video security media locally, reducing the need to continuously upload data to the cloud. Micron said cloud storage is expensive and consumes large amounts of network bandwidth.

For small businesses looking to reduce bandwidth and operational expenses or in remote sites such as cargo ships or oil rigs with limited connectivity, it can periodically upload data to the cloud for backup and rely on the i400 card at the edge.

Features of the i400 include:

  • Five years or high quality continuous 24/7 recording.
  • Concurrent handling of 4K video recording and up to eight AI events per second.
  • Two million hours of mean time to failure.

Micron is demonstrating the card at this week’s Embedded World in Nuremberg, Germany.

ASIL certification

Meanwhile, Micron has received what it claims is the first ISO 26262 automotive safety integrity level (ASIL) D certification of memory for its low-power double data rate 5 (LPDDR) DRAM.

The certification validates the DRAM as meeting strict functional safety standards required for full autonomy in intelligent vehicles as well as next generation advanced driver assistance systems (ADAS).

ABI Research estimates 25 billion connected internet of things (IoT) devices by 2026. This data will be stored, managed and analyzed at the edge for actional real-time insights.

“With edge devices generating critical insights for everything from public safety to vehicle autonomy to manufacturing operations, today’s smart applications cannot afford to compromise on latency or quality,” said Kris Baxter, corporate vice president and general manager of Micron’s Embedded Business Unit. “Micron’s newest high-performance, ruggedized solutions — our i400 microSD card for video security and automotive ASIL D-qualified LPDDR5 — will unlock new value for businesses and drive the rapid innovation needed at the intelligent edge.”

The memory will be able to unlock new ADAS technologies such as autonomous valet parking and ridesharing, traffic jam pilot and hands-free experiences that will pave the way for Level 5 autonomy.
