Data Sheet

troller designs.

The SST55LD019A/B/C high-performance ATA Flash

Disk Controller offers sustained read and write perfor-

mance up to 10.0 MB/sec. The SST55LD019A controller

is to be used when the random access performance needs

to be maximized. The SST55LD019B controller is to be

used when the sequential access performance needs to be

maximized. The SST55LD019C controller is to be used

when the flash drive capacity and sequential access perfor-

mance need to be maximized. The SST55LD019A/B/C

can directly support up to 8 flash media devices or,

through simple decoding logic, can support up to 64

flash media devices. Users can select either an internal

or external system clock option for optimal performance vs.

the supply current.

The SST55LD019A/B/C offers added security protection

for confidential information stored in the flash media. It

allows up to four protection zones which can be set by the

user to be Read-only or Hidden (Read-disabled). The ATA

Flash Disk Controller can access the data within the pro-

tected zones through a password-protected command.

The controller also provides a WP_PD# pin to protect criti-

cal information stored in the flash media from unauthorized

overwrites.

The ATA Flash Disk Controller comes pre-programmed

with a 10-byte unique serial ID. For even greater system

security, the user has the option of programming an addi-

tional 10 Bytes of ID space to create a unique, 20-byte ID.

The ATA Flash Disk Controller comes packaged in an

industry-standard, 100-lead TQFP package, an 84-ball

TFBGA package, or a 85-ball VFBGA package for easy

integration into an SMT manufacturing process.
