Industrial Temp SATA NANDrive™ MX Series

1.0

GENERAL DESCRIPTION

Each SATA NANDrive contains an integrated SATA NAND flash memory controller and discrete NAND flash die

in a BGA package. Refer to Figure 2-1 for the SATA NANDrive block diagram.

1.1

Optimized SATA NANDrive

The heart of SATA NANDrive is the SATA NAND flash

memory controller which translates standard SATA

signals into flash media data and control signals. The

following components contribute to SATA NANDrive’s

operation.

1.1.1 Microcontroller Unit (MCU)

The MCU translates SATA commands into data and

control signals required for flash media operation.

1.1.2 Internal Direct Memory Access (DMA)

SATA NANDrive uses internal DMA allowing instant

data transfer from/to buffer to/from flash media. This

implementation eliminates microcontroller overhead

associated

with

the

traditional,

firmware-based

approach, thereby increasing the data transfer rate.

1.1.3 Power Management Unit (PMU)

The PMU controls the power consumption of SATA

NANDrive. The PMU dramatically reduces the power

consumption of SATA NANDrive 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

SATA NANDrive firmware integrity. For regular power

management,

the

host

must

send

a

STANDBY_IMMEDIATE

(E0h),

IDLE_IMMEDIATE

(E1h), STANDBY (E2h) or IDLE (E3h) command and

wait for the command-ready before powering down

SATA NANDrive.

1.1.4 Embedded Flash File System

The embedded flash file system is an integral part of

SATA NANDrive. 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

flash writes across all memory address space to

increase the longevity of flash media

3.

Keeps track of the data file structure

4.

Manages system security for the selected

protection zones

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 Serial Communication Interface (SCI)

The Serial Communication Interface (SCI) is designed

for error reporting. During the product development

stage, it is recommended to provide the SCI port on

the PCB to aid in design validation.

1.1.7 Multi-tasking Interface

The multi-tasking interface enables fast, sequential

write performance by allowing concurrent Read,

Program and Erase operations to multiple flash media.

1.2

SMT Reflow Consideration

Preprogrammed NAND devices have temperature

limits due to data retention. Using Greenliant’s

recommended reflow profile during production will

help prevent damage to the device and ensure better

retention of any preprogrammed data through the

surface-mount soldering process. See the relevant

datasheet section describing the recommended reflow

temperature limits.

1.3

Advanced NAND Management

SATA

NANDrive’s

integrated

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

or select blocks in the device to prevent “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.
