Contents
The GD32A50x series are 32-bit general-purpose microcontrollers based on the Arm®
Cortex®-M33 processor.
Internal ECC RAM
Device | StartAddr | Size |
---|---|---|
GD32A503xB | 0x20000000 | 24Kb |
GD32A503xC | 0x20000000 | 32Kb |
GD32A503xD | 0x20000000 | 48Kb |
*** Additional information ***
In order to prevent errors when reading first time, the DLL intialises the first 24Kb of RAM starting at 0x2000 0000.
