Functional description

The USB-KW40Z is built around the Freescale MKW40Z160 SoC in a 48-pin LGA package. The

USB-KW40Z features a IEEE Std. 802.15.4 and BLE 2.4 GHz radio frequency transceiver and a Kinetis

family ultra low-power, mixed-signal ARM Cortex-M0+ microcontroller in a single package. This board

is intended as a simple evaluation platform and as a building block for application development. The

four-layer board provides the MKW40Z160 with its required RF circuitry and a 32 MHz reference

oscillator crystal. The layout for this base level functionality can be used as a reference layout for your

target board. Figure 5 shows a simple block diagram.
