Analog Contactless Interface consists of:
–
Rectifier
–
Voltage Regulator
–
Power on Reset
–
Modulator / Demodulator

Clock Extractor
Operational mode
The access to the memory depends on the actual mode of SLE 55R01; the memory is
accessed according to plain or protected mode when the PICC is selected.
Crypto Unit
Generates random numbers, checks and calculates message authentication code (MAC).
Memory Unit
160 bytes organised in 16 pages with 8 + 2 bytes each.
Control Unit
—
Decoding and execution of the
commands
—
Bit oriented
anticollision
method with 4 or 7 byte long serial numbers (complying to
ISO/IEC 14443-3
cascade level 1 and 2 are supported). It allows the recognition of
several cards in the field which may be selected and operated in sequence.
—
Access to key-protected sectors is only permitted after
authentication
with an appropriate
key. Only one sector is opened within a session. One sector is optionally configurable
without key protection and authentication.
—
Memory access
to the pages according to the individual access conditions programmed
for every page and every key
