Abort/Reset
An Abort/Reset command is available to allow the user
to safely abort an erase or program sequence. Two
consecutive program cycles with FFH on the data bus
will abort an erase or a program operation. The abort/
reset operation can interrupt at any time in a program or
erase operation and the device is reset to the Read
Mode.

POWER UP/DOWN PROTECTION
The CAT28F512 offers protection against inadvertent
programming during V
PP
and V
CC
power transitions.
When powering up the device there is no power-on
sequencing necessary. In other words, V
PP
and V
CC
may power up in any order. Additionally V
PP
may be
hardwired to V
PPH
independent of the state of V
CC
and
any power up/down cycling. The internal command
register of the CAT28F512 is reset to the Read Mode on
power up.
POWER SUPPLY DECOUPLING
To reduce the effect of transient power supply voltage
spikes, it is good practice to use a 0.1µF ceramic
capacitor between V
CC
and V
SS
and V
PP
and V
SS
. These
high-frequency capacitors should be placed as close as
possible to the device for optimum decoupling.
