m TECHNICAL DATA
1024 x 8-Bit nt4U.co INA25862
ee -MOS EEPROM with I C-Bus InterfaceThe INA2586 is a 8-Kbit (1024 x 8-bit) n-MOS floating gate electrically erasable programmable read only memory (EEPROM). IC
hworks in systems with serial I2C-bus. Up to two INA2586 devices may be connected to the I2C-bus.The programming of the array is
Simplemented by electron’s tunneling. The programming voltage is generated on-chip, using a voltage multiplier. Device is
tafunctionally identical to the SDA2586, Siemens. IC are made in 8-pin DIP and 8-pin SOP.
.DaFEATURES
Non-volatile storage of information during 10 years
wSingle supply (Ucc=4,75 B - 5,25 B)
wOn-chip voltage multiplier
w On-chip generator of bulk biasing
