2.3 System Performance
All performance timings assume the SDP3B
FlashDisk controller is in the default (i.e.,
fastest) mode.
Start Up Times Sleep to write:
Sleep to read:
Reset to ready:
2.5 msec maximum
2.0 msec maximum
50 msec typical
400 msec maximum
Active to Sleep Delay Programmable
Data Transfer Rate
To/From Flash
4.0 MBytes/sec burst for Type II SDP3B FlashDisk
3.0 MBytes/sec burst for Type III SDP3B FlashDisk
Data Transfer Rate
To/From Host
6.0 MBytes/sec burst
Controller Overhead Command to DRQ 1.25 msec maximum
Note: The Sleep to Write and Sleep to Read times are the times it takes the SDP3B FlashDisk to exit sleep mode
when any command is issued by the host to when the card is reading or writing. SDP3B FlashDisks do not
require a reset to exit sleep mode. See section 1.7.6.
2.4 System Reliability and
Maintenance
MTBF (@ 25°C) 1,000,000 hours for Type II SDP3B FlashDisk
500,000 hours for Type III SDP3B FlashDisk
Preventive Maintenance None
