CCT24
3.0 CCT24 Hardware
The major components of the CCT24 include a 2.4 GHz FHSS transceiver and a low current 32-bit micro-
controller. The CCT24 operates in the 2.4 GHz ISM band. The module includes nine frequency subbands
and 38 total frequency channels to support the various 2.4 GHz frequency allocations used throughout
the world. The CCT24 has three selectable RF output power levels: 1, 10, and 63 mW. Also, there are
four selectable RF transmission rates: 38.4, 115.2, 200 and 500 kb/s. The CCT24 includes a low-noise
receiver preamplifier and a high efficiency transmitter amplifier, providing excellent range in outdoor
applications.
The CCT24 provides 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 standard baud rates up to 460.8
kb/s. The SPI port supports data rates up to 80.64 kb/s. Also included are three 10-bit ADC inputs, two 8-
bit PWM outputs, and six general-purpose digital I/O ports. Four of the digital I/O ports support an option-
al interrupt-from-sleep mode when configured as inputs. The radio is available in two mounting configura-
tions. The CCT24 is designed for plug-in connector mounting.
