Chip ID for XC161

Hello Erik,

yes I have some ID's for the devices.
You can read them out from the ID-registers.
Newer devices should also use the IDRT-register for the silicon revision.
Unfortunately there were some inconsistency and so I gave it up to collect these ID's and
track the latest.

void Calculate_IDCHIP (void)
{
	unsigned int shadowreg;
	shadowreg=(IDCHIP & 0xFF00);
	printf(" Chip Identfication                 :   ");
	switch(shadowreg)
		{
		case 0x2000: printf("XC161 or XC167 ");					break;
		case 0x2300: printf("XC164 ");							break;
		default    : printf("Could not read identification ");	break;
		}
	shadowreg=(IDCHIP & 0x00FF);
	printf("   ===>  Revision Step: ");
	switch(shadowreg)
		{
		case 0x0001: printf("'AA'");							break;
		case 0x0002: printf("'AB'");							break;
		case 0x0003: printf("'AC'");							break;
		case 0x0004: printf("'AD'");							break;
		// newer steps could implemented here
		default    : printf("a step newer than 'AD'");			break;
		}
   printf("\r\n\n");
}

	printf(" Manufacturer Identfication         :   ");
	if(shadowreg==0x1800)
		{
		printf("Infineon");							// older device spec.
		}
	else
		{
		shadowreg=((IDMANUF & 0xFFE0)>>5);
		if(shadowreg==0x0C1)
			{
			printf("Infineon");						// newer device spec  0C1h = JEDEC code for Infineon

Hello Stefan,

that is exactly what I am looking for. I need to know, because Flash programming algorithm is different for step AB and AC and lateron I cannot know which hardware is at the customer to provide the correct firmware update.

Thanks a lot

Erik

Hello Erik,

yes with the AC-step the state machine for programming the FLASH has been changed.

The short code I gave you here, should work to identify a step AC and over.

Good luck
Stefan
