Electrical Specification

The following table
Characteristics for the CompactFlash Memory
Card Series.
Unless otherwise stated, conditions are:
SDCFB-XX
Vcc = 5V ±10%
Vcc = 3.3V ± 5%
Ta = 0°C to 60°C
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.
Type Parameter
IxZ Input Leakage Current
IxU Pull Up Resistor
IxD Pull Down Resistor
Note: The minimum pullup resistor leakage current meets the PCMCIA specification of 10k ohms but is
intentionally higher in the CompactFlash Memory Card Series product to reduce power use.
