Figure 4. Memory Map
Block 10h provides storage for user-programmable
parameters that are defined by the ISO/IEC 14443 stan-
dard. These are application data field and AFI. The
remaining bytes (U1, U2, U3) are not defined by the
communication standard; the application software can
use them, e.g., for proprietary markings. Block 11h con-
tains control bytes that determine the operation of the
individual pages (EPROM-emulation mode, write protec-
tion of individual blocks), or to write protect the applica-
tion data field, the AFI, and U1. The S-Lock byte, if
programmed to a suitable code, only protects itself from
future changes. The self-protection feature can be used
to permanently mark the fob as being “special, ” as
defined by the application. Table 1 illustrates the rela-
tionship between the controlling register in block 11h
and the memory area affected. Tables 2 and 3 specify
the code assignments to achieve the protection.
Besides the storage for 8 data bytes, each memory
block has 2 integrity bytes, which are not memory
mapped. The integrity bytes function as a MAX66020-
maintained, 16-bit write-cycle counter. Having
reached its maximum value of 65,535, the write-cycle
counter stops incrementing, but does not prevent
additional write cycles to the memory block. The
integrity bytes can be read through the Custom Read
Block command.
