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.
FEATURES
♦ Non-volatile storage of information during 10 years
♦ Single supply (Ucc=4,75 B - 5,25 B)
♦ On-chip voltage multiplier
♦ On-chip generator of bulk biasing
♦ Serial input/output I²C-bus
♦ 10 000 ERASE/WRITE cycles per byte;
♦ Internal reprogramming (no external components)
♦ Duration of the ERASE/WRITE cycle is 15 ms
♦ Temperature range: 0 ÷ +70⁰C
