DESCRIPTION

The M35101 is a contactless memory, powered by

the received carrier electromagnetic wave. It is a

2048-bit EEPROM, organised as 16 pages of

16 x 8 bits.

The M35101 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.
