Product Description
The GLS93MP032G3 / GLS93MR064G3 / 128G3 /256G3 Wide Temperature microSD ArmourDrive™
PX Series (referred to as microSD ArmourDrive” inthis datasheet) are high-performance, low-power flash
memory cards. They combine 32, 64, 128 or 256
GBytes of NAND flash memory with an advanced
NAND controller in a standard microSD card formfactor.

The NAND flash controller with built-in advanced
NAND management firmware communicates with thehost through the standard SD / SPI protocol. It does
not require any additional or proprietary software suchas the Flash File System (FFS) and Memory
Technology Driver (MTD). The firmware effectively
optimizes the use of NAND flash memory’s
program/erase (P/E) cycles and minimizes write
amplification.

microSD ArmourDrive is ideal for applications that
require hot-swappable, small form factor data storage
with high shock-resistance. microSD cards are widelyused in transportation systems, industrial automation,
vending and gaming machines, medical computing,professional video and photo cameras, set-top boxes
and point-of-sales (POS) equipment. These industrial
removable memory cards surpass consumer memory
cards in their security, reliability and ruggedness.

GENERAL DESCRIPTION

Each microSD ArmourDrive integrates a NAND flash memory controller with NAND flash in a multi-chip package.
Refer to Figure 2-1 for the microSD ArmourDrive block diagram.

1.1

1.1.5

Optimized microSD ArmourDrive

The ECC technology uses advanced algorithms todetect and correct errors, ensuring data integrity andextending the SSD lifespan.

The heart of microSD ArmourDrive is the NAND flash
memory controller, which translates standard SD / SPI
signals into flash media data and control signals. The
following components contribute to microSD
ArmourDrive’s operation.
1.1.1

1.1.6

1.2

Power Management Unit (PMU)

The Flash File System handles inadvertent powerinterrupts and has auto-recovery capability to ensure
microSD ArmourDrive firmware integrity.
Embedded Flash File System

1.2.1

The embedded flash file system is an integral part of
microSD ArmourDrive. It is integrated in thecontroller’s firmware that performs the following tasks:

SMART Support

Industrial microSD ArmourDrive memory cards use
Self-Monitoring, Analysis and Reporting Technology(SMART) for automatic monitoring and reporting of
the device’s health and remaining usage life. With
SMART support for advanced notifications, preventiveactions can be taken by the host to minimize any
irreversible data loss and ensure data integrity.

1. Manages and optimizes the data access of flashmedia
2. Provides flash media wear leveling to spread theflash writes across all memory address space toincrease the longevity of flash media
3. Keeps track of data file structures
1.1.4

Advanced NAND Management

microSD ArmourDrive’s controller uses advanced
wear-leveling algorithms to substantially increase thelongevity of NAND flash media. Wear caused by datawrites is evenly distributed across all available blocks
in the device that prevents “hot spots” in locations thatare programmed and erased extensively. Thiseffective wear-leveling technique results in optimized
device endurance, enhanced data retention andhigher reliability required by long-life applications.

The PMU controls the power consumption of microSD
ArmourDrive. The PMU dramatically reduces thepower consumption of microSD ArmourDrive byputting the part of the circuitry that is not in operation
into sleep mode.

1.1.3

Multi-tasking Interface

The multi-tasking interface enables concurrent Read,
Program and Erase operations to multiple NAND flashmedia.

Microcontroller Unit (MCU)

The MCU translates SD/SPI commands into data andcontrol signals required for flash media operation.
1.1.2

Error Correction Code (ECC)

Power Interrupt Data Protection

Power Interrupt Data Protection is a mechanism tohelp prevent data loss during unexpected power
failure events. Enhanced data integrity is supported by
the controller’s advanced firmware during abnormal
power loss.
