Each NANDrive contains an integrated ATA Controller and one or more NAND Flash dice in a
LBGA package. Refer to Figure 1 for the NANDrive block diagram.
The heart of the NANDrive is the ATA Flash Disk Controller which translates standard ATA signals
into flash media data and control signals. The following components contribute to the NANDrive’s
operation.
The MCU translates ATA/IDE commands into data and control signals required for flash media oper-
ation.
The NANDrive uses internal DMA allowing instant data transfer from buffer to flash media. This
implementation eliminates microcontroller overhead associated with the traditional, firmware-
based approach, thereby increasing the data transfer rate.
The power management unit controls the power consumption of the NANDrive. The PMU dramat-
ically reduces the power consumption of the NANDrive by putting the part of the circuitry that is not
in operation into sleep mode.
A key contributor to the NANDrive performance is an SRAM buffer. The buffer optimizes the host’s
data transfer to and from the flash media.
The embedded flash file system is an integral part of the NANDrive. It contains MCU firmware that
performs the following tasks:
High performance is achieved through optimized hardware error detection and correction.
The Serial Communication Interface (SCI) is designed for manufacturing error reporting. Always
provide SCI interface access to PCB design to aid in design validation.
