Unique device identifiers are suitable for:
● Used as a serial number (e.g. USB string serial number or other terminal applications)
● Use the unique ID as a security key when used in conjunction with software encryption primitives and protocols before programming the internal Flash to increase the security of the code in the Flash
● Activate the secure bootstrap process, etc.
The 96-bit unique device identifier provides a reference number that is unique to any device and any context. These bits can never be changed by the user.
The 96-bit unique device identifier can also be read in different ways such as single byte/half word/word, and then concatenated using a custom algorithm.
Base address: 0x1FFF7A10
typedef struct
{
uint32_t id[3];
}ChipID;
ChipID Get_ChipID(void)
{
ChipID chipid = {0};
chipid.id[0] = *(__I uint32_t *)(0x1FFF7A10 + 0x00);
chipid.id[1] = *(__I uint32_t *)(0x1FFF7A10 + 0x04);
chipid.id[2] = *(__I uint32_t *)(0x1FFF7A10 + 0x08);
return chipid;
}
