Microprocessor Reset
The RESET pin is asserted whenever V
CC falls below the
reset threshold voltage or when MR goes low. The reset pin
remains asserted for a period of 200ms after V
CC has risen
above the reset threshold voltage and MR goes high. The
reset function ensures the microprocessor is properly reset
and powers up into a known condition after a power failure.
RESET will remain valid with V
CC as low as 1.4V
Watchdog Timer
The microprocessor can be monitored by connecting the
WDI pin (watchdog input) to a bus line or I/O line. If a tran-
sition does not occur on the WDI pin within the watchdog
timeout period, then WDO will go low. A minimum pulse of
50ns or any transition low-to-high or high-to-low on the WDI
pin will reset the watchdog timer. The output of the watch-
dog timer (WDO) will remain high if WDI sees a valid tran-
sition within the watchdog timeout period or if WDI is left
floating. If VCC falls below the reset threshold voltage then
WDO goes low immediately regardless of WDI. If WDI is left
floating, then WDO can be used as a low line indicator.
Manual Reset
The manual-reset input (MR) allows reset to be triggered by
a pushbutton switch which is debounced by the 140ms min-
imum reset pulse width. MR can be driven by external
TTL/CMOS compatible logic. By connecting WDO to MR a
watchdog timeout will generate a reset pulse in the
ILC705/ILC706.
Power Fail Warning
An additional comparator which is independent of other
functions on the ILC705/706/707/708 is provided for early
warning of power failure. An external voltage divider can be
used to compare unregulated DC to an internal 1.25V ref-
erence. The voltage divider ratio on the input of the power
fail comparator (PFI) can be chosen so as to trip the power
fail comparator a few milliseconds before VCC falls below
the maximum reset threshold voltage. The output of the
power fail comparator (PFO) can be used to interrupt the
microprocessor when used in this mode and execute shut-
down procedures prior to power loss
