GENERAL DESCRIPTION
2.1
Basic functionality
LTCM 300U is a SMD mountable radio transmitter module enabling
the realization of gateways for 902 MHz radio systems. It provides
a bi-directional radio interface and a bi-directional serial interface.
Radio messages are sent transparently through the serial interface
in both directions from and to an externally connected host processor or host PC. In addition control commands can be sent from the
host, e.g. to configure the repeater functionality or to manage
Smart Ack functions. TCM 300U can act as postmaster for up to 20
bi-directional sensors using Smart Ack technology.

3.2.1 GPIO supply voltage - IOVDD
For digital communication with other circuitry the pins of the serial interface UART may be
operated from supply voltages different from DVDD. Therefore an interface voltage supply
pin IOVDD is available which must be connected either to DVDD or to an external supply
within the tolerated voltage range of IOVDD.
