PACKAGE/PINOUTS
PIN NAMES
PIN DESCRIPTIONS
Serial Clock (SCL)
The SCL input is used to clock all data into and out of
the device.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into
and out of the device. It is an open drain output and
may be wire-ORed with other open drain or open col-
lector outputs. An open drain requires the use of a
pull-up resistor.
Write Protect (WP)
The WP pin works in conjunction with a nonvolatile
WPEN bit to “l(fā)ock” the setting of the Watchdog Timer
control and the memory write protect bits.
Reset Output (RESET)
RESET is an active LOW, open drain output which
goes active whenever Vcc falls below the minimum
Vtrip sense level. It will remain active until Vcc rises
above the minimum Vtrip sense level for 150ms.
RESET goes active if the Watchdog Timer is enabled
and there is no start bit before the end of the select-
able Watchdog time-out period. A serial start bit will
reset the Watchdog Timer. RESET also goes active on
power up at 1V and remains active for 150ms after the
power supply stabilizes.
V2 Voltage Fail Output (V2FAIL)
V2FAIL is an active LOW, open drain output which goes
active whenever V2MON falls below the minimum V2trip
sense level. It will remain active until V2MON rises
above the minimum V2MON sense level.
DEVICE OPERATION
Power On Reset
Application of power to the X46402 activates a Power
On Reset Circuit. This circuit goes active at 1V and
pulls the RESET pin active. This signal prevents the
system microprocessor from starting to operate with
insufficient voltage or prior to stabilization of the oscil-
lator. When V
CC
exceeds the device V
200ms (nominal) the circuit releases RESET allowing
the processor to begin executing code.

Low Voltage Monitoring
During operation, the X46402 monitors the V
V2MON levels and compares these with internal, preset
voltages.
CC
and
When the internal low voltage detect circuitry senses
that V2MON is low, the V2FAIL pin goes active. Typically
this would be used by the processor as an interrupt to
stop the execution of the code or to do housekeeping in
preparation for an impending power failure.
When the internal low voltage detect circuitry senses
that V
CC
is low, the following happens:
– The RESET pin goes active.
– The Flag bit in the control register is set to zero.
– Communication to the device is interrupted and any
command is aborted. If a serial nonvolatile store is in
progress when power fails, the circuitry does not
stop the nonvolatile store operation, but attempts to
complete the operation.
The RESET and V2FAIL signals remain active until
V
CC
voltage drops below 1V. RESET remains active
until V
CC
returns and exceeds V
V2FAIL remains active until immediately after V2MON
returns and exceeds it’s minimum voltage.
