2. INTRODUCTION
The AT3515 is the low-cost, 3.5” member of the Bulldog Family of drives available today.
With a maximum capacity of 8 Gbytes in a standard 3.5” 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 AT3515 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 a 6 Mbytes per seconds for reads and 6
Mbytes/second for writes. The drive 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.
