PSOC, MCU

The Silicon ID contains silicon ID, revision ID, and family ID. The IDEs and PSoC™ Programmer use the Silicon ID to identify each device. Use the following registers to get the Silicon ID for PSoC™ 4 and PSoC™ 6 MCUs.

PSoC™ 4 MCU:

SFLASH_SILICON_ID register: Contains the silicon ID
MSB nibble of the ROMTABLE_PID2 register: Contains the major revision ID
MSB nibble of the ROMTABLE_PID3 register: Contains the minor revision ID
ROMTABLE_PID0 register: Contains the family ID

See the following sample code segment.

uint32_t siliconID = CY_GET_REG32(CYREG_SFLASH_SILICON_ID);



uint8_t majorRevisionID = (CY_GET_REG8(CYREG_ROMTABLE_PID2) >> 4);   



uint8_t minorRevisionID = (CY_GET_REG8(CYREG_ROMTABLE_PID3) >> 4);   



uint16_t familyID = (CY_GET_REG16(CYREG_ROMTABLE_PID0) & 0x0FFF);   



    printf("\r\n Silicon ID: 0x%X Major Revision: 0x%X Minor Revision: 0x%X Family ID: 0x%X \r\n", siliconID, majorRevisionID, minorRevisionID, familyID );

PSoC™ 6 MCU:

SFLASH_SILICON_ID register: Contains the 16-bit silicon ID
SFLASH_SI_REVISION_ID register: Contains the revision ID
SFLASH_FAMILY_ID register: Contains the family ID

See the following sample code segment.

uint8_t revisionID = CY_GET_REG8(SFLASH_BASE + 0x01); 



uint16_t siliconID = CY_GET_REG16(SFLASH_BASE + 0x02); 



uint16_t familyID  = (CY_GET_REG16(SFLASH_BASE + 0x0c) & 0x0FFF); 



printf("\r\n Silicon ID: 0x%X Revision: 0x%X Family ID: 0x%X \r\n", siliconID, revisionID, familyID);
