The
KK
F8594E is
а
4-Kbit (512
х
8-bit) floating gate electrically erasable
programmable read only memory
(
ЕЕР
PROM). By using an internal redundant
storage code it is fault tolerant to single bit errors. This feature dramatically
increases reliability compared to conventional
ЕЕР
R
ОМ
memories.
Power consumption is low due to the full
СМО
S technology used. The
programming voltage 1s generated on-chip, using
а
voltage multiplier.
As data bytes are received and transmitted via the serial I
2
C-bus,
а
package using eight pins is sufficient. Up to four
KK
F8594E devices may
be
connected to the I
c
-bus. Chip select is accomplished by two address inputs.
Timing of the Erase/Write cycle is done internally, thus no external com-
ponents are required. Pin 7 must be connected to either V
DD
or left open-circuit.
There is an option of using an external clock or timing the length of an
Erase/Write cycle.
A write protection input (pin 1) allows disable of write-commands from
the master by
а
hardware signal. When pin 1 is HIGH and one of the upper 256
ЕЕР
R
ОМ
cells is addressed, then the data bytes will not be acknowledged by
the
KK
F8594E and the
ЕЕР
R
ОМ
contents are not changed.
