Pin 1:
PBRST
- Pushbutton reset input. This input is debounced and can be driven with external logic signals or by
means of a mechanical pushbutton to actively force a reset. All pulses less than 1ms in duration on the
PBRST pin are ignored, whereas, any pulse with a duration of 20ms or greater is guaranteed to cause a
reset. PBRST has an internal pull-up resistor to VCC of 40k
typical.
Pin 2:
TD
- Time delay input. This input selects the timebase used by the watchdog timer. When TD = 0V, the
watchdog timeout period is set to a nominal value of 150ms and when TD = open, the watchdog timeout
period is set to a nominal value of 600ms and when TD = VCC, the watchdog timeout period is 1.2sec
nominally.
Pin 3:
TOL
- Tolerance select input. Selects whether 5% or 10% of VCCis used as the reset threshold voltage.
When TOL = 0V, the 5% tolerance level is selected and when TOL = VCC, a 10% tolerance level is selected.
Pin 4:
GND
- IC ground pin, 0V reference.
Pin 5:
RST
- RST is asserted high if either VCCgoes below the reset threshold, the watchdog times out or PBRST is
pulled low for a minimum of 20ms. RST remains asserted for one reset timeout period after VCCexceeds the
reset threshold or after the watchdog times out or after PBRST goes high.
Pin 6:
RST
- RST is asserted low if either VCCgoes below the reset threshold, the watchdog times out or PBRST is
pulled low for a minimum of 20ms. RST remains asserted for one reset timeout period after VCCexceeds the
reset threshold or after the watchdog times out or after PBRST goes high.
Pin 7:
ST
- Input to the watchdog timer. If ST does not see a transition from high to low within the watchdog timeout
period, RST and RST will be asserted.
Pin 8:
VCC
- Primary supply input.
