    ... The CYRF6936 WirelessUSB™ LP radio is a second generation member of the Cypress WirelessUSB Radio System-On-Chip (SoC) family. The CYRF6936 is interoperable with the first generation CYWUSB69xx devices. The CYRF6936 IC adds a range of enhanced features, including increased operating voltage range, reduced supply current in all operating modes, higher data rate options, reduced crystal start up, synthesizer settling, and link turnaround times ...

    ... It changes to lower data rates at longer distances or in high inter- ference environments or both. In addition, the CYRF6936 IC has a Power Management Unit (PMU), which enables direct connection of the device to any battery voltage in the range 1.8V to 3.6V. The PMU conditions the battery voltage to provide the supply voltages required by the device, and may supply external devices ...

    ... The CYRF6936 IC supports packets up to 255 bytes. However, the actual maximum packet length depends on the accuracy of the clock on each end of the link and the data mode. Interrupts are provided to allow an MCU to use the transmit and receive buffers as FIFOs ...

  • Page 5

    ... Similarly, when receiving packets in transaction mode, firmware must retrieve the fully received packet in response to an interrupt request indicating reception of a packet. Data Rates The CYRF6936 IC supports the following data rates by combining the PN code lengths and data transmission modes described in the previous sections: ■ ...

    ... Registers may therefore be read from or written to when the device is in sleep mode, and the 12 MHz oscillator disabled. The SPI interface and the IRQ and RST pins have a separate voltage reference pin (V directly to MCUs operating at voltages below the CYRF6936 IC supply voltage. Figure 4.

    ... HIGH or active LOW, and be either a CMOS or open drain output. The available interrupts are described in the section on page 13. The CYRF6936 IC features three sets of interrupts: transmit, receive, and system interrupts. These interrupts all share a single pin (IRQ), but can be independently enabled or disabled. The contents of the enable registers are preserved when switching between transmit and receive modes ...
