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 VPP and VCC power transitions.
When powering up the device there is no power-on
sequencing necessary. In other words, VPP and VCC
may power up in any order. Additionally VPP may be
hardwired to VPPH independent of the state of VCC 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 0.1
F ceramic
capacitor between VCC and VSS and VPP and VSS. These
high-frequency capacitors should be placed as close as
possible to the device for optimum decoupling.
