The TRH031M is one of
3ALogics AnyRead™ family of highly integrated multi-protocol reader IC for
contactless communication at 13.56MHz.
The TRH031M supports all layers
of the ISO14443 Type A, Type B and ISO 15693 standard communication protocol.
The internal transmitter part is able to drive an antenna designed for
proximity operation distance (up to 100mm) directly without additional active
circuitry.
TRH031M also supports vicinity standard card protocol (ISO
15693) and can communicate up to 1.5M with external power amplifier in ISO
15693 mode.
The receiver part of TRH031M provides a robust and efficient
implementation of a demodulation and decoding circuitry for signals form
ISO14443 Type A, Type B and ISO 15693 compatible cards.
The digital part
of TRH031M handles the complete framing and error detection. Also it supports
serial or parallel interfaces which allows connection to any 8-bit or 16-bit
microprocessor.
