The CYRF69103 PRoC LP is targeted for the following applications:
• Wireless HID devices Mice Remote Controls Presenter tools Barcode scanners POS terminal
• General purpose wireless applications Industrial applications Home automation White goods Consumer electronics Toys

Functional Description

PRoC LP devices are integrated radio and microcontroller functions in the same package to provide a dual-role single-chip solution. Communication between the microcontroller and the radio is through the radio’s SPI interface.

Functional Overview

The CYRF69103 is a complete Radio System-on-Chip device, providing a complete RF system solution with a single device and a few discrete components. The CYRF69103 is designed to implement low cost wireless systems operating in the worldwide GHz Industrial, Scientific, and Medical ISM frequency band GHz to GHz .

GHz Radio Function The SoC contains a 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 . In DSSS modes the baseband performs DSSS spreading/despreading, while in GFSK Mode 1 Mb/s - GFSK the baseband performs Start of Frame SOF , End of Frame EOF 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, except SDR, enabling the implementation of mixed-rate systems in which different devices use different data rates. This also enables the implementation of dynamic data rate systems, which use high data rates at shorter distances and/or in a low moderate interference environment, and change to lower data rates at longer distances and/or in high interference environments.

The radio meets the following worldwide regulatory requirements:
• Europe ETSI EN 301 489-1 V1.4.1 ETSI EN 300 328-1 V1.3.1
• North America FCC CFR 47 Part 15
• Japan ARIB STD-T66

Data Transmission Modes The radio supports four different data transmission modes:
• In GFSK mode, data is transmitted at 1 Mbps, without any DSSS
• In 8DR mode, 1 byte is encoded in each PN code symbol transmitted
• In DDR mode, 2 bits are encoded in each PN code symbol transmitted
• In SDR mode, a single bit is encoded in each PN code symbol transmitted

Both 64-chip and 32-chip data PN codes are supported. The four data transmission modes apply to the data after the Start of Packet SOP . In particular, the packet length, data and CRC are all sent in the same mode.

Microcontroller Function The MCU function is an 8-bit Flash-programmable microcontroller. The instruction set is optimized specifically for HID and a variety of other embedded applications. The MCU function has up to 8 Kbytes of Flash for user’s code and up to 256 bytes of RAM for stack space and user variables. In addition, the MCU function includes a Watchdog timer, a vectored interrupt controller, a 16-bit Free Running Timer, and 12-bit Programmable Interrupt Timer. The microcontroller has 15 GPIO pins grouped into multiple ports. With the exception of the four radio function GPIOs, 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 GPIO Port 0 has two dedicated pins that have independent interrupt vectors The microcontroller features an internal oscillator. The PRoC LP includes a Watchdog timer, a vectored interrupt controller, a 12-bit programmable interval timer with configurable 1 ms interrupt and a 16-bit free running timer. In addition, the CYRF69103 IC has a Power Management Unit PMU , which enables direct connection of the device to any battery voltage in the range V to V. The PMU conditions the battery voltage to provide the supply voltages required by the device and may supply external devices.

Backward Compatibility The CYRF69103 IC is fully interoperable with the main modes of the first generation Cypress radios namely the CYWUSB6934 -LS and CYWWUSB6935-LR devices. The kbps mode is supported by selecting 32 chip DDR mode. Similarly, the kbps mode is supported by selecting 64 chip SDR mode In this method, a suitably configured CYRF69103 IC device may transmit data to or receive data from a first generation device, or both. Backwards compatibility requires disabling the SOP, length, and CRC16 fields.

This section provides the different configurations of the registers and firmware that enable a new generation radio to communicate with a first generation radio. There are two possible modes SDR and DDR mode 8-DR and GFSK modes are not present in the first generation radio . The second generation radio must be initialized using the RadioInitAPI of the LP radio driver and then the following registers’ bits need to be configured to the given Byte values. Essentially, the following deactivates the added features of the second generation radio and takes it down to the level of the first generation radio. The data format, data rates, and the PN codes used are recognizable by the first generation radio.

Description 32 chip PN Code, DDR, PA = 6 AGC is enabled. LNA and attenuator are disabled. Fast turnaround is disabled, the device uses high side receive injection and Hi-Lo is disabled. Overwrite to receive buffer is enabled and the RX buffer is configured to receive eight bytes maximum. AutoACK is disabled. Forcing end state is disabled. The device is configured to transition to Idle mode after a Receive or Transmit. ACK timeout is set to 128 µs. All SOP and framing features are disabled. Disable LEN_EN = 0 if EOP is needed. Disable Transmit CRC-16. The receiver rejects packets with a zero seed. The Rx CRC-16 Checker is disabled and the receiver accepts bad packets that do not match the seed in CRC_seed registers. This helps in communication with the first generation radio that does not have CRC capabilities. Set ALL SLOW. When set, the synthesizer settle time for all channels is the same as the slow channels in the first generation radio. Sets the number of allowed corrupted bits to Sets the number of consecutive symbols for non-correlation to detect end of packet. AAAA are the two preamble bytes. Any other byte can also be written into the preamble register file. Recommended counts of the preamble bytes to be sent must be

Package Handling

Some IC packages require baking before they are soldered onto a PCB to remove moisture that may have been absorbed after leaving the factory. A label on the packaging has details about actual bake temperature and the minimum bake time to remove this moisture.The maximum bake time is the aggregate time that the parts are exposed to the bake temperature. Exceeding this exposure time may degrade device reliability.
