Memory Space Allocation
The Wi-Fi SOC MX1070 of the EMW3076 module contains the following memories:
⚫ ROM
Starting at address 0x0000_0000 is a read-only memory of size 24k bytes. The BOOT image is stored in
the ROM, which is mainly used to program the Flash, and performs safe boot or normal startup according
to the mode selection, and guides the application image running in the Flash.
⚫ SRAM
256kbytes of SRAM, which can be used not only to execute code, store data, but also to share the shared
memory of Wi-Fi message buffers. The starting address of the SRAM is 0x0800_0000.
⚫ Flash
The MX1070 integrates a 2M byte QPSI Flash through the System-in-Package (SiP) package. The
processor uses the cache to retrieve code and data from Flash and supports redirection to encrypt code
and data.
⚫ OTP (One-Time Programmable Memory)
The MX1070 offers 512-byte One-Time Programmable (OTP) storage. The user available area is: 0xD7 -
0x1F7. Other space pre-stores hardware configuration parameters such as Flash encryption information,
MAC address, and RF calibration parameters. The system automatically reads each time after reset.
The system storage space address is assigned as follows:
