Electrical specification
Table 10 defines the DC characteristics for the CompactFlash memory card. Unless
otherwise stated, conditions are:
●
VCC = 5 V ± 10%
●
VCC =3.3 V ± 10%
●
-40 °C to 85 °C
Table 11 shows that the card operates correctly in both the voltage ranges and that the
current requirements must not exceed the maximum limit shown.
4.3
Current measurement
The current is measured by connecting an amp meter in series with the VCC supply. The
meter should be set to the 2 A scale range, and have a fast current probe with an RC filter
with a time constant of 0.1 ms. Current measurements are taken while looping on a data
transfer command with a sector count of 128. Current consumption values for both read and
write commands are not to exceed the maximum average RMS current specified in
Table 11. Table 12 shows the Input leakage current, Table 13 the Input characteristics,
Table 14 the Output drive type and Table 15 the Output drive characteristics.
