Chip Identification Number
The XC858 identity (ID) register is located at Page 1 of address B3_H. The value of ID
register is 49_H. However, for easy identification of product variants, the Chip
Identification Number, which is an unique number assigned to each product variant, is
available. The differentiation is based on the product, variant type and device step
information.
Two methods are provided to read a device’s chip identification number:
• In-application subroutine, GET_CHIP_INFO
• Bootstrap loader (BSL) mode A
Table 31 lists the chip identification numbers of available XC858 Flash device variants.
