Communication between the microcontroller and the radio is via the SPI interface between both functions. Functional Overview The CYRF69313 is a complete Radio System-on-Chip device, providing a complete RF system solution with a single device and a few discrete components. The CYRF69313 is designed to implement low cost wireless systems operating in the worldwide 2.4 GHz Industrial, Scientific, and Medical (ISM) frequency band (2.400 GHz–2.4835 GHz). 2.4 GHz Radio Function The SoC contains a 2.4 GHz, 1 Mbps GFSK radio transceiver, packet data buffering, packet framer, DSSS baseband controller, Received Signal Strength Indication (RSSI), and SPI interface for data transfer and device configuration. The radio supports 98 discrete 1 MHz channels (regulations may limit the use of some of these channels in certain jurisdictions). The baseband performs DSSS spreading/despreading, Start of Packet (SOP), End of Packet (EOP) detection, and CRC16 generation and checking. The baseband may also be configured to automatically transmit Acknowledge (ACK) handshake packets whenever a valid packet is received. When in receive mode, with packet framing enabled, the device is always ready to receive data transmitted at any of the supported bit rates. This enables the implementation of mixed-rate systems in which different devices use different data rates. This also enables the implementation of dynamic data rate systems that use high data rates at shorter distances or in a low-moderate interference environment or both. It changes to lower data rates at longer distances or in high interference environments or both. USB Microcontroller Function The microcontroller function is based on the powerful CYRF69313 microcontroller. It is an 8-bit Flash programmable microcontroller with integrated low speed USB interface. The microcontroller has up to 14 GPIO pins to support USB, PS/2 and other applications. Each GPIO port supports high impedance inputs, configurable pull-up, open drain output, CMOS/TTL inputs and CMOS output. Up to two pins support programmable drive strength of up to 50 mA. Additionally each I/O pin can be used to generate a GPIO interrupt to the microcontroller. Each GPIO port has its own GPIO interrupt vector with the exception of GPIO Port 0. The microcontroller features an internal oscillator. With the presence of USB traffic, the internal oscillator can be set to precisely tune to USB timing requirements (24 MHz ± 1.5%). The PRoC LPstar has up to 8 Kbytes of Flash for user’s firmware code and up to 256 bytes of RAM for stack space and user variables. Backward Compatibility The CYRF69313 IC is fully interoperable with the main modes of the second generation Cypress radio SoC namely the CYRF6936, CYRF69103 and CYRF69213. CYRF69313 IC device may transmit data to or receive data from a second generation device, or both. |
