ZHCSM59B November 2014 – September 2020 CC3100MOD
PRODUCTION DATA
The device interfaces to an external host using the SPI. The CC3100 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.
#SWAS0319677 shows the SPI host interface.
Table 8-3 lists the SPI host interface pins.
PIN NAME | DESCRIPTION |
---|---|
HOST_SPI_CLK | Clock (up to 20 MHz) from MCU host to CC3100 device |
HOST_SPI_nCS | CS (active low) signal from MCU host to CC3100 device |
HOST_SPI_MOSI | Data from MCU host to CC3100 device |
HOST_INTR | Interrupt from CC3100 device to MCU host |
HOST_SPI_MISO | Data from CC3100 device to MCU host |
nHIB | Active-low signal that commands the CC3100 device to enter hibernate mode (lowest power state) |
