TECHNICAL DATA
INA2586
The INA2586 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 INA2586 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.
