d. Suppose a 32-bit microcontroller has 256KB of internal EEPROM memory. We wish to save a text file in its EEPROM. The text file contains 389250 characters. The program to do this will occupy 1000 registers in the same memory on the MCU. Determine whether the internal memory of the MCU will suffice or if external EEPROM must be purchased. If the latter holds what minimum capacity of the external EEPROM is needed? d. Suppose a 32-bit microcontroller has 256KB of internal EEPROM memory. We wish to save a text file in its EEPROM.
