AS1910 - AS1915
Dual-Voltage Microprocessor Supervisory Circuits
with Manual Reset and Watchdog
Data Sheet
www.austriamicrosystems.com Revision 1.00 1 - 15
1 General Description
The AS1910 - AS1915 microprocessor supervisory cir-
cuits were designed to generate a reset when one of the
two monitored supply voltages falls below a factory-
trimmed threshold, and to maintain the reset for a mini-
mum timeout period when both supplies are above their
reset thresholds. Guaranteed to be in the correct state
for VCC higher than +1.0V, these devices are ideal for
multiple-voltage systems with strict monitoring require-
ments.
The AS1913/AS1914/AS1915 feature factory-trimmed
thresholds to monitor a primary voltage between 1.8 and
3.6V, and a secondary voltage between 0.9 and 2.5V.
For the AS1910/AS1911/AS1912, a secondary monitor-
ing voltage can be user-adjusted via an external resistor
divider down to 0.6V.
The devices are available with th e reset output types
listed in Table 1.
The AS1910 - AS1915 include a manual -reset input for
systems that never fully power down the microproces-
sor . Additionally , these devices feature a watchdog timer
to help ensure that the processor is operating within
proper code boundaries.
The AS1910 - AS1915 are available in a 6-pin SOT23
package.

RESETN
Active-Low Reset Output (AS1910, AS1912, AS1913, AS1915). The RESETN signal
toggles from high to low when VCC, VCC2, or RESETIN input drops below the factory-trimmed
reset threshold (see Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a
reset. This output signal remains low for the reset timeout period after all supervised voltages
exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset.
RESET
Active-High Reset Output (AS1911, AS1914). The RESET signal toggles from low to high
when VCC, VCC2, or RESETIN input drops below the factory-trimmed reset threshold (see
Table 4 on p age 4), or MRN is pulled low, or the watchdog triggers a reset. This output signal
remains high for the reset timeout period (see tRP on page 5) after all supervised voltages
exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset.
2GND
Ground
3MRN
Active-Low Manual Reset Input. Pulling this pin low asserts a reset. This pin is connected
to the internal 50kΩ pullup to VCC. This reset remains active as long as MRN is low and for
the reset timeout period (se e tRP on page 5) after MRN goes high.
Note: If the manual reset feature is not used, th is pin should be unconnected or connected
to VCC.
4WDI
Watchdog Input. If WDI remains hig h or low fo r longer than the watchdog timeout period
(see tWD on page 6), the internal watchdog timer period expires and a reset is triggered for
the reset timeout period (see tRP on page 5). The internal watchdog timer clears whenever a
reset is a asserted or when WDI senses a rising or fallin g edge.
Note: To disable the watchdog feature, this pin must be unconnected or connected to a tri-
state buffer output.
5RESETIN User-Adjustable Supervised Voltage Input (AS1910/AS1911/AS1912). Th is high-
impedance pin serves as the input to the internal reset comparator. Connect this pin to an
external resistor-divider network to set the reset threshold voltage (down to 0.63V).
VCC2 Primary Supervised Voltage Input (AS1913/AS1914/AS1915). This pin serves as the
secondary supervised voltage input.
6VCC Primary Supervised Voltage In put. This pin serves as the primary supervised voltage input.

8 Detailed Description
The AS1910 - AS1915 supervisory circuits were designed to generat e a reset when one of the two monitored supply
voltages falls below its factory-trimmed trip threshold (see VTH on page 4 and VTH2 on page 4), and to maintain the
reset for a minimum timeout pe riod (see tRP on page 5) after all supplies have stabilized.
The integrated watchdog timer (see Watchdog Input on page 10) helps mitigate aga inst bad programming code or
clock signals, and/or poor peripheral response. An active-low manual reset input (see Manual Reset Input on page 10)
allows for an externally activated system reset.
RESET/RESETN
Whenever one of the monitored voltages falls below its reset threshold, the RESET output (AS1910, AS1912, AS1913,
AS1915) asserts low or the RESETN output (AS1911, AS1914) asserts high. Once all monitored voltages have stabi-
lized, an internal timer keeps the reset asserted for the reset timeout period (tRP). After the tRP period, the RESET or
RESETN output return to their original state (see Figure 10).

RESETIN
The AS1910/AS1911/AS1912 feature a user-adjustable supervisory voltage input (RESETIN). The threshold voltage
for RESETIN is between 0. 61 and 0.65V (0.63 typ).
Figure 12. Voltage Monitoring Circuit
To monitor a voltage higher than 0.63V, connect a resistor divider network to the circuit as shown in Figure 12. For the
circuit shown in Figure 12, the threshold at VMONITOR is:
VMONITOR_TRIP = 0.63 V [(R 1 + R2)/R2](EQ 1)
Note: Since RESETIN is powered by VCC, VRESETIN must not be larg er than VCC.

Watchdog Input
The integrated watchdog feature can be used to monitor processor activity via pin WDI, and can detect pulses as short
as 50ns. The watchdog require s that the processor toggle the watchdog logic input at regular intervals, within a speci-
fied minimum timeout period (1.5s, typ). A reset is asserted for the reset timeout period. As long as reset is asserted,
the timer remains cleared and is not incremented. When reset is deasserted, the watchdog timer starts counting
(Figure 11).
Note: The watchdog timer can be cleared with a reset pulse or by toggling WDI.
Figure 13. Watchdog Timing Relationship
The watchdog is internal ly driven low during most (87.5%) of the watchdog timeout period (see tWD on page 6) and
high for the rest of the watc hdog timeout period. When pin WDI is left unconnected, thi s i nternal driver clears the
watchdog timer every 1.4s. When WDI is tri-stated or is not connected, the maximum allowable leakage current is
10µA and the maximum allowable load capacitance is 200pF.
Note: The watchdog fun c tion can be disabled by l eaving pin WDI unconnected or connecting it to a tri-state output
buffer.
Manual Reset Input
The active-low pin MRN is used to force a manual reset. This input can be dri v en by CMOS logic levels or with open-
drain collector outputs.
Pulling MRN low asserts a reset which will remain asserted as long as MRN is kept low , and for the timeout period (see
tRP on page 5) after MRN goes high (140ms min). The manual reset circuitry has an internal 50kΩ pullup resistor , thus
it can be left open if not used.
To create a manual-reset circuit, connect a normally open momentary switch from pin MRN to GND (see Figure 1 on
page 1); external debounce circuitry is not required in this configuration.
If MRN is driven via long cables or the device is used in a noisy environment, a 0.1µF capacitor between pin MRN and
GND will provide additional noise immunity.
tRST
The RESET signal is the inverse of the RESETN signal.

9 Application Information
Watchdog Input Current
The watchdog input is driven through an internal buffer and an int ernal series resistor from the watchdog timer (see
Figure 1 1 on p age 9). When pin WDI is left unconnected (watchdog disabled), the watchdog timer is serviced within the
watchdog timeout period (see tWD on page 6) by a low-high-low pulse from the counter chain. For minimum watchdog
input current (minimum overall po wer consumption), pull WDI low for most of the watchdog timeout period, pulsing it
low-high-low once within the first 7/8 (87. 5%) of the watchdog timeout perio d to reset the watchdog timer.
Note: If WDI is externally driven high for the ma jority of the timeout period, up to 160µA can flow into pin WDI.
Interfacing to Bi-Directional CPU Reset Pins
Since the reset outputs of the AS1912 and AS1915 are open drain, these devices interface easily with processors that
have bi-directional reset pins. Connecting the processor reset output directly to the AS1912/AS1915 RESETN pin with
a single pullup resistor (see Figure 14) allows the AS1912/AS1912 to assert a reset.
Figure 14. AS1912 or AS1915 RESETN-to-CPU Bi-Directional Reset Pin
Fast Negative-Going Transients
Fast, negative-going VCC transients normally do not require the CPU to be shutdown. The AS1910 - AS1915 are virtu-
ally immune to such transients. Resets are issued to the CPU during power-up, powerdown, and brownout conditions.
Note: VCC transients that go 100mV below the reset threshold and last ≤ 55µs typically will not assert a reset pulse.
Valid Reset to VCC = 0
The AS1910 - AS1915 are guaranteed to operate properly down to VCC = 1V. For applications requiring valid reset lev-
els down to VCC = 0, a pulldown resistor to active-low outputs (push/pull only) and a pullup resistor to active-high out-
puts (push/pull only) will ensure that the reset line is valid during the interval where the reset output can no longer sink
or source current.
Watchdog Tips
Careful consideration should be taken when implementing the AS1910 - AS1915 watchdog feature.
One method of supervising software code execution is to set/reset the watchdog inp ut at different places in the code,
rather than pulsing the watchdog input high-low-high or low-high-low. This method avoids a loop condition in which the
watchdog timer would conti nue to be reset inside the loop, preventing the watchdog from ever timing out.
Figure 15 shows a flowchart where the input/output driving the watchdog is set high at the beginning of the routine, set
low at the beginning of every subroutine, then set hig h again when the routine returns to the beginning. If the routine
should hang in a subroutine, the problem would quickly be corrected, since the I/O is continually set low and the watch-
dog timer is allowed to t ime out, causing a reset or interrupt to be issued (see Watchdog Input Current on page 11).
This method results in higher averaged WDI input current over time than a case where WDI is held low for the majority
(87.5%) of the time out period and periodically pulsing it low-high-low.
