Nations N32G03x

The Nations N32G032x are general-purpose microcontroller based on the Arm® Cortex®-M0 core.

Flash Banks

Internal Flash

Flash Bank	Base address	Size	J-Link Support
Main Flash	0x08000000	Up to 64 KB
Option Byte	0x1FFFF600	Up to 26 B

Option Byte Flash

Erasing the option byte flash without programming it immediately afterwards will activate RDP1 level protection. Our option byte flashloader works best if RDP1 level protection stays deactivated. For this reason any explicit erase operation will be skipped by our flashloader. Instead, any necessary erase operation is implicitly executed during flash programming. It is therefore recommended to only perform programming operations on the option byte flash.

Watchdog Handling

• The device has up to two watchdogs IWDG and WWDG.
• WWDG is not present on N32G033 devices.
• Both watchdogs are fed during flash programming.

Device Specific Handling

Reset

• The devices uses normal Cortex-M reset, no special handling necessary, like described here.
