The BAT32G1xxGx series (BAT32 family) are 32-bit general-purpose microcontrollers based on the Arm® Cortex®-M0 processor.
Internal ECC RAM
Device | StartAddr | Size |
---|---|---|
BAT32G133xAxxxx | 0x20000000 | 4 KB |
BAT32G133xCxxxx | 0x20000000 | 4 KB |
BAT32G157xHxxxx | 0x20000000 | 32 KB |
BAT32G157xKxxxx | 0x20000000 | 32 KB |
*** Additional information ***
In order to prevent errors when reading first time, the DLL intialises the first 4Kb of RAM
starting at 0x2000_0000.
Due to this attaching to a running system is not possible.
