6.0 DNT24 Hardware
Figure 6.0.1
The major components of the DNT24 series modules include a 2.4 GHz FHSS transceiver and a low
current 8-bit microcontroller. The DNT24 modules operate in the 2.4 GHz MHz ISM band. There are 12
selectable hopping patterns providing compatibility with frequency allocations in most regions of the
world. DNT24 modules also have two selectable RF output power levels: 10 mW and 63 mW.

The DNT24 modules provide a variety of hardware interfaces. There are two serial ports plus one SPI
port. Either the primary serial port or the SPI port can be selected for data communications. The second
serial port is dedicated to diagnostics. The primary and diagnostic serial ports support most standard
baud rates up to 250.0 kbps. The SPI port supports data rates up to 500 kbps. Also included are three
ADC inputs, two DAC outputs and six general-purpose digital I/O ports. Four of the digital I/O ports sup-
port an optional interrupt-from-sleep mode when configured as inputs.

There are four module configurations in the DNT24 Series:
- The DNT24C is designed for use with an external antenna and for solder reflow mounting.
- The DNT24P is designed for use with an external antenna and for plug-in connector mounting.
- The DNT24CA has a built-in chip antenna and is designed for solder reflow mounting.
- The DNT24PA has a built-in chip antenna and is designed for plug-in connector mounting.
