technical da t a 1024 x 8-bit n-mos eeprom with i 2 c-bus interface the INA2586 is a 8-kbit (1024 x 8-bit) n-mos floating gate elect rically erasable programmable read only memory (eeprom). ic works in sy ste m s with se ria l i 2 c-bus. up to two INA2586 devices may be connected to the i 2 c-bus.the programming of the array is im plem ented by electron?s tunneling. the program m i ng voltage is generated on-chip, using a voltage m u ltiplier. device is functionally identical to the sda2586, siemens. ic are made in 8-pin dip and 8-pin sop. features ? non-volatile storage of inform ation during 10 y ears ? single supply (ucc=4,75 b - 5,25 b) ? on-chip voltage m u ltiplier ? on-chip generator of bulk biasing ? serial input/output i 2 c-bus ? 10 000 erase/write cy cles per by te; ? internal reprogramming (no external components) ? duration of the erase/write cy cle is 15 ms ? temperature range: 0 +70 0 c electrical characteristics p a r a m e t e r c o n d i tion s s y mb o l min . m a x supply current, ma u cc =5.25 b i cc0 - 2 0 , 0 output low voltage (sda), v i ol =3 m a u cc =4.75b u ol - 0 , 4 high leakage current: -on output (sda), a -on inputs scl, sda, a -on inputs cs, tp1, tp2, a u oh =5,25 b u ih =5,25 b u ih =5,25 b i l oh i lih i lih - - - 10,0 10,0 100,0 input capacitance, pf u i = 0 b c i - 1 0 , 0 clock input frequency , khz f scl 0 1 0 0 reprogram m i ng cy cle tim e, m s eras e and w r ite t pro g 1 0 , 0 2 0 , 0 eras e of die cy cle tim e, m s u tp2 = 5,0 b t er - 2 0 , 0 the number of e/w cy cles on 1 by te 10 000 - input high voltage: -inputs sda, scl, v -inputs cs, tp1, tp2, v u ih 3,0 4,5 u cc u cc input low voltage: -inputs sda, scl, v -inputs cs, tp1, tp2, v u il - - 1,5 0,2 INA2586 pin assignment 5 6 7 8 4 3 2 1 sda scl tp3 ucc pin description s y m b o l p i n d e s c r i p t i o n uss cs tp 1 tp 2 sda scl tp 3 ucc 1 2 3 4 5 6 7 8 gnd chip selection testing pin testing pin (0v - normal mode, 5v - chip eras ing) informational line, input/output clock input testing pin, not connected supply voltage u cs tp1 tp2 1
