3.3 Electrical Specification
All D.C. Characteristics for the CompactFlash Memory Card Series are defined as follows:
Typical conditions unless otherwise stated:
V
CC
= 5V +/- 10% Tolerant
V
CC
= 3.3V +/- 5%
Ta = 0° C to 60° C
Absolute Maximum Conditions:
V
CC
= -0.3V min. to 6.5V max.
V* = 0.5V min. to V
CC
+ 0.5V max.
*Voltage on any pin except V
CC
with respect to GND.
3.3.1 Input Leakage Control and Input Characteristics
In Table 3-5, “x” refers to the characteristics described in Table 3-6. For example–"I1U"
indicates a pull-up resistor with a Type 1 input characteristic.
Table 3-5 Input Leakage Control
Type Parameter Symbol Conditions MIN MAX Unit
lxZ Input Leakage Current IL Vih=VCC/Vil=GND -1 1 uA
IxU Pull Up Resistor RPU1 VCC=5.0V 50k 500k Ohm
IxD Pull Down Resistor RPD1 VCC=5.0V 50k 500k Ohm
NOTE: The minimum pull-up resistor input leakage is 50k ohms rather than the 10k ohms
stated in the PCMCIA PC Card specification.
