TECHNICAL DATA

KKA2586

1024 x 8-Bit n-MOS EEPROM with I²C-Bus Interface

The KKA2586 is a 8-Kbit (1024 x 8-bit) n-MOS floating gate electrically erasable programmable read only memory (EEPROM). IC

works in systems with serial I²C-bus. Up to two KKA2586 devices may be connected to the I²C-bus.The programming of the array is

implemented by electron’s tunneling. The programming voltage is generated on-chip, using a voltage multiplier. Device is

functionally identical to the SDA2586, Siemens. IC are made in 8-pin DIP and 8-pin SOP.
