TECHNICAL DATA
512 x 8-bit CMOS EEPROMS with I²C-
bus Interface
The KKF8594E is а 4-Kbit (512 х 8-bit) floating gate electrically erasable
programmable read only memory (ЕЕРPROM). By using an internal redundant
storage code it is fault tolerant to single bit errors. This feature dramatically
increases reliability compared to conventional ЕЕРRОМ memories.
Power consumption is low due to the full СМОS technology used. The
programming voltage 1s generated on-chip, using а voltage multiplier.
As data bytes are received and transmitted via the serial I²C-bus, а
package using eight pins is sufficient. Up to four KKF8594E 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
ЕЕРRОМ cells is addressed, then the data bytes will not be acknowledged by
the KKF8594E and the ЕЕРRОМ contents are not changed.
