This section of the training module will provide a general overview of the wireless options available from TI compatible with the MSP430 families. MSP430 and TI’s Low Power Wireless transceivers are a perfect fit for low power, wireless solutions. Both families were designed from the ground up with low power in mind and both have Standby modes consuming ~500na. All MSP430 devices are compatible as communication is done with SPI and a couple of GPIO lines for status. Software libraries are available online preconfigured for MSP430 peripherals including USART, USCI A/B , USI & bit banged IO. Both device families share the power supply requirements of very low VCC = 1.8V-3.6V allowing them to run on the same, simple power source. Depending on application requirements, there are a number of MSP430 options that would be a good fit. TI recommends the F22xx and F41x for cost efficient designs running simple RF stacks and only requiring limited amounts of analog and communications while mid-ranged applications may use the F16x or the F24x. For high-end applications requiring large amounts of analog integration and large flash/RAM sizes such as ZigBee based designs, the FG461x or the F261x would be an excellent fit. Radio modules are often selected based on their frequency of operation which is driven by the regional FCC regulations and the range requirements of the system. All CC1xxx are <1GHz transceivers (400 & 900 MHz) and the CC2xxx are 2.4GHz devices. Additionally, the CC24xx devices have on chip peripherals that support ZigBee based applications.
