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
