This slide shows some of the important features of SPIRIT1 separated into four quadrants. The antenna diversity algorithm is shown in the upper left. The SPIRIT1 features one pin that is able to control an external switch in order to select the best antenna for the communication. With this feature it is possible to program the threshold and the SPIRIT1 will automatically switch from one antenna to the other, depending on the receive strength of the communication. Usually this functionality is handled directly by the host microcontroller, so SPIRIT1 frees resources in the host MCU. For power consumption, the SPIRIT1 provides operating modes to lower the consumption and out-performs the competition. It features an embedded SMPS that allows the power consumption to be as low as 24 mW. Looking at the competitor, it is possible to see that using an external DC/DC converter, the power consumption is 32 mW (higher than SPIRIT1). Comparing the sensitivity (the capability for the receiver to receive a very weak signal), it can be seen that SPIRIT1 is able to receive a signal with -120 dBm while the competitor has a sensitivity of -111 dBm, meaning longer range for the SPIRIT1. Additionally, the SPIRIT1 is part of the DASH-7 alliance, with low power and high robustness, a very wide range and a global frequency which is defined at 433 MHz. Location capabilities are enabled, and the device is available in a small form factor. These are all the DASH-7 alliance requirements for the part.
