Data Sheet
General Description
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.
Performance-optimized NANDrive
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.
Microcontroller Unit (MCU)
The MCU translates ATA/IDE commands into data and control signals required for flash media operation.
Internal Direct Memory Access (DMA)
The NANDrive uses internal DMA allowing instant data transfer from buffer to flash media. This imple-
mentation eliminates microcontroller overhead associated with the traditional, firmware-based
approach, thereby increasing the data transfer rate.
Power Management Unit (PMU)
The power management unit controls the power consumption of the NANDrive. The PMU dramatically
reduces the power consumption of the NANDrive by putting the part of the circuitry that is not in opera-
tion into sleep mode.
SRAM Buffer
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.
Embedded Flash File System
The embedded flash file system is an integral part of the NANDrive. It contains MCU firmware that per-
forms the following tasks:
1.
Translates host side signals into flash media writes and reads.
2.
Provides dynamic flash media wear leveling to spread the flash writes to increase the lon-
gevity of flash media.
3.
Keeps track of data file structures.
Error Correction Code (ECC)
High performance is achieved through optimized hardware error detection and correction.
Serial Communication Interface (SCI)
The Serial Communication Interface (SCI) is designed for manufacturing error reporting. Always pro-
vide SCI interface access to PCB design to aid in design validation.
Multi-tasking Interface
The multi-tasking interface enables fast, sustained write performance by allowing concurrent Read,
Program, and Erase operations to multiple flash media devices.
