Power-on Reset (POR)
A Power-on Reset pulse is generated on-chip when
V
DD
rise is detected (in the range of 1.2V - 1.7V). To
take advantage of the POR, just tie the MCLR pin
directly (or through a resistor) to V
DD
. This will
eliminate external RC components usually needed to
create Power-on Reset. A minimum rise time for V
DD
must be met for this to operate properly. See Electrical
Specifications for details.
When the device starts normal operation (exits the
reset condition), device operating parameters (voltage,
frequency, temperature, ...) must be meet to ensure
operation. If these conditions are not met, the device
must be held in reset until the operating conditions
are met.
For additional information, refer to Application Note
AN607, "Power-up Trouble Shooting"
The POR circuit does not produce an internal reset
when V
DD
declines.
8.5
Power-up Timer (PWRT)
The Power-up Timer (PWRT) provides a fixed 72 ms
nominal time-out (T
PWRT
) from POR (Figure 8-10,
Figure 8-11, Figure 8-12 and Figure 8-13). The
Power-up Timer operates on an internal RC oscillator.
The chip is kept in reset as long as the PWRT is active.
The PWRT delay allows the V
DD
to rise to an accept-
able level (Possible exception shown in Figure 8-13).
A configuration bit, PWRTE, can enable/disable the
PWRT. See either Figure 8-1 or Figure 8-2 for the oper-
ation of the PWRTE bit for a particular device.
The power-up time delay T
PWRT
will vary from chip to
chip due to V
DD
, temperature, and process variation.
See DC parameters for details.
8.6
Oscillator Start-up Timer (OST)
The Oscillator Start-up Timer (OST) provides a 1024
oscillator cycle delay (from OSC1 input) after the
PWRT
delay
ends
(Figure 8-10,
Figure 8-12 and Figure 8-13). This ensures the crystal
oscillator or resonator has started and stabilized.
The OST time-out (T
OST
) is invoked only for XT, LP and
HS modes and only on Power-on Reset or wake-up
from SLEEP.
When V
DD
rises very slowly, it is possible that the
T
PWRT
time-out and T
OST
time-out will expire before
V
DD
has reached its final value. In this case
(Figure 8-13), an external power-on reset circuit may
be necessary (Figure 8-9).
Figure 8-11,
FIGURE 8-9:
EXTERNAL POWER-ON
RESET CIRCUIT (FOR SLOW
V
DD
POWER-UP)
Note 1: External Power-on Reset circuit is
required only if V
DD
power-up rate is too
slow. The diode D helps discharge the
capacitor quickly when V
DD
powers down.
2: R < 40 k
is recommended to make sure
that voltage drop across R does not exceed
0.2V (max leakage current spec on MCLR
pin is 5
μ
A). A larger voltage drop will
degrade V
IH
level on the MCLR pin.
3: R1 = 100
to 1 k
will limit any current
flowing into MCLR from external
capacitor C in the event of an MCLR pin
breakdown due to ESD or EOS.
