The SkyeModule™ M1 HF (13.56 MHz) RFID embedded reader module provides a low power, high performance, and cost effective platform designed to enable any device with RFID reader technology.
The M1 is a multi-protocol 13.56MHz OEM module capable of reading and
writing to transponders based on ISO 15693, ISO 14443A, and ISO18000-3
air-interface protocols. The M1 features an on-board antenna as well as the
ability to attach a standard 50 Ohm external antenna for improved read-range.
Four interface options are available to provide communication to a variety of
host systems: RS232 or TTL/ serial, I2C, and SPI. With its' on-board power
regulator circuit, the M1 can operate from 1.8-5.0V; while the power management
intelligence allows current to be set as low as 60 μA (Sleep Mode)
making it ideal for use in battery operated devices. Further power efficiency is
gained by use of the Start-Up command in which one stores a command to
be executed once the M1 is awoke from Sleep Mode. The M1 has 8 programmable
GPIO pins for the addition of peripheral devices. Software-adjustable
baud rates from 4800 to 57600 bits per second offer compatibility with most
systems. Field upgradeable firmware provides forward compatibility for adding
future tag protocols and features.
