DESCRIPTION
The M35102 is a contactless memory, powered by
the received carrier electromagnetic wave. It is a
1792-bit EEPROM, plus 256-bit ROM, organised
as 16 pages of 16 x 8 bits.
The M35102 conforms to the ISO 14443-2 Type-B
recommendation for the transfer of power and sig-
nals via radio transmission. The card reader cir-
cuitry amplitude modulates (10% modulation) the
data on the carrier using amplitude shift keying
(ASK). The card replies by load modulating the
data on the carrier using bit phase shift keying
(BPSK) of the subcarrier. The data transfer rate in
each direction is 106 Kbit/second.
