PRELMNARY
X40420/X40421 – Preliminary
Characteristics subject to change without notice.
14 of 25
REV 1.2.14 7/12/02

Word Address
The word address is either supplied by the master or
obtained from an internal counter.
Operational Notes
The device powers-up in the following state:
– The device is in the low power standby state.
– The WEL bit is set to ‘0’. In this state it is not possible
to write to the device.
– SDA pin is the input mode.
– RESET/RESET Signal is active for
t
PURST
.
Data Protection
The following circuitry has been included to prevent
inadvertent writes:
– The WEL bit must be set to allow write operations.
– The proper clock count and bit sequence is required
prior to the stop bit in order to start a nonvolatile write
cycle.
– A three step sequence is required before writing into
the Control Register to change Watchdog Timer or
Block Lock settings.
– The WP pin, when held HIGH, prevents all writes to
the array and all the Register.
