Hey Corey, Thanks for this interresting question. These measurement are absolutly normal. - You changed the sampling time of the ADC inside the ADC block. - The model time-step was fixed at 100Khz (T = 10us) (quite high).

It is not possible to replace RAM by EEPROM.
however, you may try to activate simulink optimization, try to check the box "inline parameters". This may save a lot of RAM memory.
