... Pinouts The CYRF7936 CyFi™ Transceiver is a Radio IC designed for low power embedded wireless applications. Combined with Cypress’s PSoC programmable system-on-chip and a CyFi network protocol stack, CYRF7936 can be used to implement a complete CyFi wireless system. XTAL V V BAT1 V V BAT2 RF Table 1.

... It changes to lower data rates at longer distances or in high inter- ference environments or both. In addition, the CYRF7936 IC has a Power Management Unit (PMU), which allows 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 ...

... 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 CYRF7936 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. interface supporting The SPI interface and the IRQ and RST pins have a separate voltage reference pin (V directly to MCUs operating at voltages below the CYRF7936 IC supply voltage.

... LOW, and be either a CMOS or open drain output. The available interrupts are described in the section Register Descriptions page 12. The CYRF7936 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 ...
