I
CC
versus Frequency and Voltage
The I
CC
consumed by the processor is composed of
two components:
1. I
PD
DThe quiescent current that represents inter-
nal device leakage. Measured with all inputs at
either V
CC
or ground and no clock applied.
2. I
CCS
DThe switching current used to charge and
discharge internal parasitic capacitance when
changing logic levels. I
CCS
is related to both the
frequency of operation and the device supply
voltage (V
CC
). I
CCS
is given by the formula:

Measuring C
PD
on a device like the 80C186EC
would be difficult. Instead, C
PD
is calculated using
the above formula with I
CC
values measured at
known V
CC
and frequency. Using the C
PD
value, the
user can calculate I
CC
at any voltage and frequency
within the specified operating range.

PDTMR Pin Delay Calculation
The PDTMR pin provides a delay between the as-
sertion of NMI and the enabling of the internal
clocks when exiting Powerdown Mode. A delay is
required only when using the on chip oscillator to
allow the crystal or resonator circuit to stabilize.
NOTE:
The PDTMR pin function does not apply when
RESIN is asserted (i.e. a device reset while in Pow-
erdown is similar to a cold reset and RESIN must
remain active until after the oscillator has stabilized.
To calculate the value of capacitor to use to provide
a desired delay, use the equation:
440

(5V, 25

Where:
t

Round up to a standard (available) capacitor value.
NOTE:
The above equation applies to delay time longer
than 10
m
s and will compute the
TYPICAL
capaci-
tance needed to achieve the desired delay. A delay
variance of
a
50% to
b
25% can occur due to
temperature,
voltage,
and
tremes. In general, higher V
CC
and/or lower tem-
peratures will decrease delay time, while lower V
CC
and/or higher temperature will increase delay time.
