2. INTRODUCTION
The AT2515 is the low cost member of the Bulldog family of drives available today. With a
capacity of 8 Gbytes in a standard 2.5” drive form factor, it delivers exceptional value for its
features. It is completely solid state, with no moving parts. This accounts for the unit’s
exceptional ruggedness and wide operating temperature range.
The AT2515 employs sector erasable NAND EEPROMs (Flash) to deliver up to 8 Gbytes of
uncompressed, non-volatile solid state storage in an extremely small, rugged form factor.
Sustained host data throughput is 6 Mbytes per seconds for reads and 6 Mbytes/second for
writes. The drive supports up to PIO Mode-4 and DMA Mode-2 IDE bus access. It is 100%
IDE compatible and requires no special drivers to operate. It is essentially a drop in
replacement for standard rotating media.
The IDE interface is implemented using an application specific IDE Flash controller with an
integrated 72-bit Reed-Solomon error detection and on-the-fly correction mechanism that
enhance data reliability. The ECC circuitry, in conjunction with the controller’s remapping
algorithms, makes for a virtually bulletproof medium for data retention.
The drive is available in a number of standard capacities ranging from 128 Mbytes to 8
Gbytes. Please contact the factory with your capacity requirements. Disk compression
utilities may be used to effectively double the usable capacity of the drive.
Each drive is fully tested under environmental and voltage extremes, to guarantee data
integrity in even the harshest conditions.
