Electrical Specification
The following table
defines
all
D.C.
Characteristics for the SDP3B FlashDisk.
Unless otherwise stated, conditions are:
SDP3B
SDP3BI
Vcc = 5V ±10%
Vcc = 5V ± 5%
Vcc = 3.3V ± 5%
Vcc = 3.3V ± 5%
Ta = 0°C to 60°C
Ta = -40°C to 85°C
Absolute Maximum
conditions are:
Vcc = -0.3V min. to 7.0V max.
V* = -0.5V min. to Vcc + 0.5V max.
* Voltage on any pin except Vcc with respect to
GND.
4.3.1
Input Leakage Current
Note:
In the table below, x refers to the characteristics described in section 4.3.2. For example, I1U indicates a
pull up resistor with a type 1 input characteristic.

Note:
The minimum pullup resistor leakage current meets the PCMCIA specification of 10k ohms but is
intentionally higher in the SDP3B FlashDisk to reduce power use.
