5.3 EEPROM Read/Write and Check
6.1 Microcontroller Manufacturer Distinction
For EEPROM, the device provides read, erase, write and check functions. As shown in
Figure 5.3.1, you can click the corresponding button directly on the interface. Please
note that all chip data will be lost after erasing, and the original data of the chip will be
erased automatically when clicking ‘Write'.
The device supports reading and writing microcontrollers from multiple
manufacturers. Among common automotive electronic modules, the microcontroller
manufacturers used include Atmel, Motorola, Freescale, Infineon, Renesas,
STMicroelectronics, etc. As shown in Figure 6.1.1.

6 Microcontroller Read/Write Operation
The microcontroller function is mainly used for data reading and writing of
various automotive electronic modules and automotive computer modules.
It is especially suitable for automobile circuit module repair. Before using
this function, you need to understand some principles and common
knowledge of microcontroller.
Multi-PROG supports reading, writing, and programming various common
brands of microcontrollers. Before data reading and writing, you should
make the correct wiring connections according to the software wiring
diagram corresponding to the brand, model, and microcontroller series. For
some models, the microcontroller requires soldering minimum system
circuit before reading.
6.2 Microcontroller Memory Area Division
Microcontroller usually has three storage spaces: program area, data area and
configuration area. The program area stores the program data of the microcontroller.
The data area stores the information data of the microcontroller. And the configuration
area stores the corresponding configuration data of the microcontroller, such as the
encryption byte option, the startup byte option, and so on. When reading and writing
microcontroller data, it is necessary to distinguish by different areas. In software,
names such as FLASH, CFLASH, CODE, and ROM are usually used to represent the
program area. The names such as DFLASH, EEPROM, DATA, INF, etc. are represent the
data area. The names such as Config are represent the configuration area. Please note
that the configuration area may be unreadable for encrypted chips.
