Capacitance

Note:

Capacitance limits are guaranteed by characterization.

Power Supply Current

For the following typical system specification shown in

Figure 11, ICC has been measured at 4.0 mA per MHz

of system clock. For the following typical system

specification shown in Figure 12, ICC has been

measured at 5.9 mA per MHz of system clock. The

typical system is measured while the system is

executing code in a typical application with maximum

voltage and maximum case temperature. Actual power

supply current is dependent on system design and may

be greater or less than the typical ICC figure presented

here.

Typical current in Figure 11 is given by:

ICC = 4.0 mA ⋅ freq(MHz)

Typical current in Figure 12 is given by:

ICC = 5.9 mA ⋅ freq(MHz)

Please note that dynamic ICC measurements are de-

pendent upon chip activity, operating frequency, output

buffer logic, and capacitive/resistive loading of the out-

puts. For these ICC measurements, the devices were

set to the following modes:

n No DC loads on the output buffers

n Output capacitive load set to 35 pF

n AD bus set to data only

n PIOs are disabled

n Timer, serial port, refresh, and DMA are enabled

Table 9 shows the variables that are used to calculate

the typical power consumption value for each version

of the Am186ESLV and Am188ESLV microcontrollers.
