Industrial Temp SD / microSD ArmourDrive™ EX Series

GENERAL DESCRIPTION
Each SD/microSD ArmourDrive integrates a NAND flash memory controller with NAND flash in a multi-chip
package. Refer to Figure 2-1 for the SD/microSD ArmourDrive block diagram.
1.1
Optimized SD/microSD ArmourDrive
The heart of SD/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 SD/microSD
ArmourDrive’s operation.
1.1.1
Microcontroller Unit (MCU)
The MCU translates SD/SPI commands into data and
control signals required for flash media operation.
1.1.2
Power Management Unit (PMU)
The
PMU
controls
the
power
consumption
of
SD/microSD ArmourDrive. The PMU dramatically
reduces the power consumption of SD/microSD
ArmourDrive by putting the part of the circuitry that is
not in operation into sleep mode.
The Flash File System handles inadvertent power
interrupts and has auto-recovery capability to ensure
SD/microSD ArmourDrive firmware integrity.
1.1.3
Embedded Flash File System
The embedded flash file system is an integral part of
SD/microSD ArmourDrive. It contains MCU firmware
that performs the following tasks:
1.
Translates host side signals into flash media
writes and reads
2.
Provides flash media wear leveling to spread the
flash writes across all memory address space to
increase the longevity of flash media
3.
Keeps track of data file structures
1.1.4
Power Interrupt Data Protection
Power Interrupt Data Protection is a mechanism to
help prevent data loss during unexpected power
failure events. Enhanced data integrity is supported by
the controller’s advanced firmware during abnormal
power loss.
1.1.5
Error Correction Code (ECC)
The ECC technology uses advanced algorithms to
detect and correct errors, ensuring data integrity and
extending the SSD lifespan.
1.1.6
Multi-tasking Interface
The multi-tasking interface enables concurrent Read,
Program and Erase operations to multiple NAND flash
media.
1.2
Advanced NAND Management
SD/microSD ArmourDrive’s controller uses advanced
wear-leveling algorithms to substantially increase the
longevity of NAND flash media. Wear caused by data
writes is evenly distributed across all available blocks
in the device that prevents “hot spots” in locations that
are
programmed
and
erased
extensively.
This
effective wear-leveling technique results in optimized
device endurance, enhanced data retention and
higher reliability required by long-life applications.
1.2.1
SMART Support
Industrial SD/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,
preventive actions can be taken by the host to
minimize any irreversible data loss and ensure data
integrity.
