This section describes the key functions and features
supported by the SC14WSMDATA (shown in Figure 2.)
3.1
The SC14WSMDATA internal hardware consist of:
• An Internal Microprocessor (MCU) running from
• A 4kByte EEPROM used by the protocol stack and
• Voltage regulators and a charge pump to convert the
• Two 2.5mA/5mA LED current sources.
• Two general purpose 10-bit ADC inputs (55us
• General Purpose Input/Output (GPIO) ports which
the device is active.
• Internal timer or dedicated digital wake up pin to
• A 10.368 MHz XTAL clock. This crystal is

• A DECT Radio transceiver with built-in antenna
• A programming interface to upload embedded SW.
3.2
The SC14WSMDATA can be controlled via embedded
software using an AT Command Set based API. In
the module development kit Dialog provides Athena,
which is an Eclipse based easy to use development
environment to develop the embedded user SW. The
basic functionality of the API can be grouped into three
categories:
• Configuring stack and system
• Sending and receiving data
• Using Hardware Features through Hardware
A detailed description of the SW architecture can be
found in document reference [2].
