Characteristics subject to change without notice
Program-Verify Mode
A Program-verify cycle is performed to ensure that all
bits have been correctly programmed following each
byte programming operation. The specific address is
already latched from the write cycle just completed, and
stays latched until the verify is completed. The Program-
verify operation is initiated by writing C0H into the
command register. An internal reference generates the
necessary high voltages so that the user does not need
to modify V
Erase) for specific timing parameters.
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 CAT28F010 offers protection against inadvertent
programming during V
When powering up the device there is no power-on
sequencing necessary. In other words, V
may power up in any order. Additionally V
hardwired to V
any power up/down cycling. The internal command
register of the CAT28F010 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 V
high-frequency capacitors should be placed as close as
possible to the device for optimum decoupling.
