PIC16F630/676
9.3.1
PIC16F630/676 devices have a noise filter in the
MCLR Reset path. The filter will detect and ignore
small pulses.
It should be noted that a WDT Reset does not drive
MCLR pin low.
The behavior of the ESD protection on the MCLR pin
has been altered from previous devices of this family.
Voltages applied to the pin that exceed its specification
can result in both MCLR Resets and excessive current
beyond the device specification during the ESD event.
For this reason, Microchip recommends that the MCLR
pin no longer be tied directly to V
network, as shown in Figure 9-5, is suggested.
An internal MCLR option is enabled by setting the
MCLRE bit in the Configuration Word. When enabled,
MCLR is internally tied to V
option is available for the MCLR pin.
FIGURE 9-5:
9.3.2
The on-chip POR circuit holds the chip in Reset until
V
operation. To take advantage of the POR, simply tie the
MCLR pin through a resistor to V
external RC components usually needed to create
Power-on Reset. A maximum rise time for V
required. See Section 12.0 “Electrical Specifica-
tions” for details. If the BOD is enabled, the maximum
rise time specification does not apply. The BOD cir-
cuitry will keep the device in Reset until V
V
(BOD)”).
When the device starts normal operation (exits the
Reset condition), device operating parameters (i.e.,
voltage, frequency, temperature, etc.) must be met to
ensure operation. If these conditions are not met, the
device must be held in Reset until the operating
conditions are met.

9.3.3
The Power-up Timer provides a fixed 72 ms (nominal)
time-out on power-up only, from POR or Brown-out
Detect. The Power-up Timer operates on an internal
RC oscillator. The chip is kept in Reset as long as
PWRT is active. The PWRT delay allows the V
rise to an acceptable level. A Configuration bit, PWRTE
can disable (if set) or enable (if cleared or
programmed) the Power-up Timer. The Power-up
Timer should always be enabled when Brown-out
Detect is enabled.
The Power-up Time delay will vary from chip to chip
and due to:
• V
• Temperature variation
• Process variation.
See DC parameters for details (Section 12.0 “Electri-
cal Specifications”).
9.3.4
The Oscillator Start-up Timer (OST) provides a 1024
oscillator cycle (from OSC1 input) delay after the
PWRT delay is over. This ensures that the crystal
oscillator or resonator has started and stabilized.
The OST time-out is invoked only for XT, LP and HS
modes and only on Power-on Reset or wake-up from
Sleep.
