ZHCSOK7B March 2020 – May 2021 CC3130
PRODUCTION DATA
The device interfaces to an external host using the SPI interface. The CC3130 device can interrupt the host using the HOST_INTR line to initiate the data transfer over the interface. The SPI host interface can work up to a speed of 20 MHz.
Figure 8-17 shows the SPI host interface.
Table 8-5 lists the SPI host interface pins.
PIN NAME | DESCRIPTION |
---|---|
HOST_SPI_CLK | Clock (up to 20 MHz) from MCU host to CC3130 device |
HOST_SPI_nCS | CS (active low) signal from MCU host to CC3130 device |
HOST_SPI_MOSI | Data from MCU host to CC3130 device |
HOST_INTR | Interrupt from CC3130 device to MCU host |
HOST_SPI_MISO | Data from CC3130 device to MCU host |
nHIB | Active-low signal that commands the CC3130 device to enter hibernate mode (lowest power state) |
