DESCRIPTION
The M35102 is a contactless memory, powered by
the received carrier electromagnetic wave. It is a
1792-bit EEPROM, pl us 256-bit ROM, orga nised
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 signals via radio transmission. The card reader circuitry amplitude modulates (10% m odulation) 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 th e su bc arrier. The d at a tr a n sfe r ra te in
each direction is 106 Kbit/second.
