Unknown EEprom help
« on: April 26, 2019, 02:18:26 pm »
This chip is from the toner of a Lexmark MX321 printer toner.  The numbers I got from it are H1828553 and I am trying to read from it with an Arduino 2560 but haven't a clue where to start.  Anyone help I do know the pinout for the connection between the toner and printer and have it connected already but I do not know the commands yet.

you want to reset the toner ?

on alibaba search :   Toner-reset-chip-for-Lexmark

normally on 4 pins pcb toners chips  you have to find the +vcc and ground supply lines and with the 2 remaining pins  you have to fine the data lines, reset pins etc ... and fit your arduino accordingly

Are you sure it's an eeprom? I skimmed through alibaba search and I see some toner reset chips boards with eeprom on it, some with two chips (one looks like a memory, second one like some uC), or even some that have two many_pin chips.
I guess that yours might be a microcontroller of some sort that has eeprom memory inside and communicates with i2c, or something like that.
