2 / 79 page 2 Data Sheet ATA Flash Disk Controller SST55LD019A / SST55LD019B / SST55LD019C ©2006 Silicon Storage Technology, Inc. S71241-04-000 12/06 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. |
