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 via
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
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).
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 world-wide regulatory require-
ments:
■ 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 trans-
mitted
■ 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 microcon-
troller. The instruction set has been optimized specifically for HID
and a variety of other embedded applications.
The MCU function has up to eight 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 IO 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. GPIO Port 0
has three dedicated pins that have independent interrupt vectors
(P0.3 - P0.4).
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 with capture
registers.
In addition, the CYRF69103 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.
