System Power Requirements - SanDisk SDP3B Product Manual

1.6.1

System Power Requirements

The system power requirements for the SDP3B
FlashDisk are different from those of the SDP5A
FlashDisk. The two tables below show the
DC Input Voltage (VCC)
100 mV max. ripple (p-p)
+5 V Currents
(maximum Average value)
See Notes 1 to 3.
Note 1. All values quoted are typical at ambient temperature and nominal supply voltage unless otherwise stated.
Note 2. Sleep mode currently is specified under the condition that all card inputs are static CMOS levels and in a
"Not Busy " operating state.
Note 3. The currents specified show the bounds of programmability of the product.
Model SDP5A
DC Input Voltage (VPP) (Note 4)
DC Input Voltage (VCC)
100 mv max. ripple (p-p)
+5 V Currents
(maximum average value)
See Notes 1 to 5
Note 1. Sleep mode current is specified under the condition that all FlashDisk inputs are at static CMOS levels and
in a "Not Busy" operating state.
Note 2. The currents specified show the complete range of programmability in the PC Card ATA FlashDisk. A
tradeoff between performance and maximum current used can be done using the Set Features command.
The FlashDisk defaults to the fastest speed and highest current. See the Set Features command for more
details.
Note 3. For information on peak currents during power on, hot insertion and writing, please contact SanDisk
Technical Support at (408) 542-0400.
Note 4. The Vpp pins are not connected in this product.
Note 5. At maximum performance, typical average Read current is 70 mA and typical average write current is
100 mA.
