Functional Description

PRoC LPstar 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 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.
