† Notice: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at those or any other conditions above those indicated in the
operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.

RST output is forced low. There is a current through the internal pull-up resistor.
This includes the current through the internal pull-up resistor and the reset power-up timer.
This specification allows this device to be used in PIC® microcontroller applications that require In-Circuit Serial
Programming™ (ICSP™) (see device-specific programming specifications for voltage requirements). This specification
DOES NOT allow a continuous high voltage to be present on the open-drain output pin (VOUT). The total time that the
VOUT pin can be above the maximum device operational voltage (5.5V) is 100s. Current into the VOUT pin should be
limited to 2 mA and it is recommended that the device operational temperature be maintained between 0°C to 70°C
(+25°C preferred). For additional information, please refer to Figure 2-33.
This parameter is established by characterization and not 100% tested.

APPLICATION INFORMATION
4.1
For many of today’s microcontroller applications, care
must be taken to prevent low-power conditions that can
cause many different system problems. The most
common causes are brown-out conditions, where the
system supply drops below the operating level
momentarily. The second most common cause is when
a slowly decaying power supply causes the
microcontroller to begin executing instructions without
sufficient voltage to sustain volatile memory (RAM),
thus producing indeterminate results. Figure 4-1 shows
a typical application circuit.
MCP102/103/121/131 are voltage supervisor devices
designed to keep a microcontroller in reset until the
system voltage has reached and stabilized at the
proper level for reliable system operation. These
devices also operate as protection from brown-out
conditions.

Note 1: Resistor RPU may be required with the
MCP121 due to the open-drain output.
Resistor RPU may not be required with
the MCP131 due to the internal pull-up
resistor. The MCP102 and MCP103 do
not require the external pull-up resistor.
FIGURE 4-1:
Typical Application Circuit.
RST Operation
The RST output pin operation determines how the
device can be used and indicates when the system
should be forced into reset. To accomplish this, an
internal voltage reference is used to set the voltage trip
point (VTRIP). Additionally, there is a hysteresis on this
trip point.
When the falling edge of VDD crosses this voltage
threshold, the reset power-down timer (tRPD) starts.
When this delay timer times out, the RST pin is forced
low.
When the rising edge of VDD crosses this voltage
threshold, the reset power-up timer (tRPU) starts. When
this delay timer times out, the RST pin is forced high,
tRPU is active and there is additional system current.
The actual voltage trip point (VTRIPAC) will be between
the minimum trip point (VTRIPMIN) and the maximum
trip point (VTRIPMAX). The hysteresis on this trip point
and the delay timer (tRPU) are to remove any “jitter” that
would occur on the RST pin when the device VDD is at
the trip point.
Figure 4-2 shows the waveform of the RST pin as
determined by the VDD voltage, while Table 4-1 shows
the state of the RST pin. The VTRIP specification is for
falling VDD voltages. When the VDD voltage is rising, the
RST will not be driven high until VDD is at VTRIP + VHYS.
Once VDD has crossed the voltage trip point, there is
also a minimal delay time (tRPD) before the RST pin is
driven low.

MCP102/103/121/131
Negative Going VDD Transients
The minimum pulse width (time) required to cause a
reset may be an important criterion in the
implementation of a Power-on Reset (POR) circuit.
This time is referred to as transient duration, defined as
the amount of time needed for these supervisory
devices to respond to a drop in VDD. The transient
duration time is dependent on the magnitude of VTRIP –
VDD. Generally speaking, the transient duration
decreases with increases in VTRIP – VDD.
Figure 4-3 shows a typical transient duration versus
reset comparator overdrive, for which the
MCP102/103/121/131 will not generate a reset pulse. It
shows that the farther below the trip point of the
transient pulse goes, the shorter the duration of the
pulse required to cause a reset gets. Figure 2-32
shows the transient response characteristics for the
MCP102/103/121/131.
A 0.1 µF bypass capacitor, mounted as close as
possible to the VDD pin, provides additional transient
immunity (refer to Figure 4-1).

Reset Power-up Timer (tRPU)
Figure 4-4 illustrates the device’s current states. While
the system is powering down, the device has a low
current. This current is dependent on the device VDD
and trip point. When the device VDD rises through the
voltage trip point (VTRIP), an internal timer starts. This
timer consumes additional current until the RST pin is
driven (or released) high. This time is known as the
Reset Power-up Time (tRPU). Figure 4-4 shows when
tRPU is active (device consuming additional current).

EFFECT OF TEMPERATURE ON
RESET POWER-UP TIMER (TRPU)
The Reset Power-up timer time-out period (tRPU)
determines how long the device remains in the reset

Typical responses for different VDD values and
temperatures are shown in Figures 2-26, 2-27 and 2-28.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
