NAME
FUNCTION
1—
RESET
Active-Low Open-Drain or Push-Pull Reset Output. RESET transitions from high to
low when VCC drops below the selected reset threshold, MR is pulled low, or the
watchdog timer expires. RESET remains low for the reset timeout period after
VCC exceeds the device reset threshold, MR deasserts, or after the watchog
timer expires. Push-pull RESET outputs are referenced to VCC. Open-drain
RESET outputs require an external pullup resistor.
22
GND
Ground
33
MR
Active-Low Manual Reset Input. Drive MR low to initiate a reset. The reset output
remains asserted while MR is held low and for the reset timeout period after MR
transitions high. Leave MR unconnected or connect to VCC if unused. MR is
internally pulled up to VCC through 10k
.
44
WDI
Watchdog Input. If WDI remains high or low for longer than the watchdog timeout
period, the internal watchdog timer expires, and a reset is triggered for the reset
timeout period. The internal watchdog timer clears whenever reset is asserted,
the manual reset is asserted, or WDI sees a rising or falling edge.
55
VCC
Supply Voltage. Input for VCC reset monitor. For noisy systems, bypass VCC with
a 0.1F capacitor to GND.
—1
RESET
Active-High Push-Pull Reset Output. RESET transitions from low to high when
VCC drops below the selected reset threshold, MR is pulled low, or the watchdog
timer expires. RESET remains high for the reset timeout period after VCC exceeds
the device reset threshold, MR deasserts, or after the watchdog timer expires.
RESET is referenced to VCC.
