Industrial NVMe BGA SSD Guide

1. Executive Summary

The Loongtion NVMe BGA SSD is a fully China-domestic solid-state storage solution designed for embedded, industrial, and ruggedized applications requiring high reliability, wide temperature tolerance, and supply chain independence. This product integrates a proprietary Loongtion NVMe controller with Yangtze Memory TLC NAND Flash in a compact BGA291 package (20 mm × 16 mm × ~1.3 mm, weight <10 g). It operates over PCIe 3.0 using the NVMe 1.4 protocol, supports both native TLC (Triple-Level Cell) and pseudo-SLC (pSLC) modes, and employs a local-DRAM-less architecture with Host Memory Buffer (HMB) to reduce BOM cost and power consumption.

Key capabilities include:

• Dual-mode operation: TLC for capacity-optimized storage (256 GB, 512 GB) or pSLC for enhanced endurance and performance (32 GB, 64 GB, 128 GB).
• Industrial temperature grade: –40 °C to +85 °C; wide/military grade: –55 °C to +105 °C (screened parts).
• Low power consumption: As low as 1.6 W (pSLC read) and up to 3.1 W (TLC write).
• Performance envelope: Sequential read up to 1200 MB/s (pSLC), 4 KB random write up to 120 K IOPS; total bytes written (TBW) up to 600 TB in pSLC mode.
• Built-in protection features: Smart erase, power-loss notification, secure erase trigger, intelligent thermal throttling, and multiple data encryption mechanisms.

Target applications include embedded systems, industrial controllers, ruggedized computers, avionics, aerospace, defense, and marine electronics. The product is available in five standard capacities with two temperature grades, as detailed in Section 10 (Ordering Information).

2. Product Overview
