Functional Overview

The CYRF69303 is a complete Radio System-on-Chip device, providing a complete RF system solution with a single device and a few discrete components. The CYRF69303 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 to 2.4835 GHz).

Features

■ Radio System-on-Chip with built-in 8-bit MCU in a single device.

■ Operates in the unlicensed worldwide Industrial, Scientific, and Medical (ISM) band (2.400 GHz to 2.483 GHz).

■ On Air compatible with second generation radio WirelessUSB? LP and PRoC LP.

■ Pin-to-pin compatible with PRoC LP except the pin 31 and pin 37.

Low Power

■ 21 mA operating current (Transmit at –5 dBm)

■ Sleep current less than 1 ?A

■ Operating voltage from 2.7 V to 3.6 V DC

■ Fast startup and fast channel changes

■ Supports coin cell operated applications

Reliable & Robust

■ Receive sensitivity typical –90 dBm

■ AutoRate? - Dynamic Data Rate Reception

■ Operating temperature from 0 °C to 70 °C

■ Closed-loop frequency synthesis for minimal frequency drift

Simple Development

■ Auto transaction sequencer (ATS): MCU can remain in sleep state longer to save power

■ Framing, length, CRC16, and Auto ACK

■ Separate 16 byte transmit and receive FIFOs

■ Receive signal strength indication (RSSI)

■ Built-in serial peripheral interface (SPI) control while in Sleep Mode

■ Advanced development tools based on Cypress’s PSoC? tools

■ Flexible I/O

■ 2 mA source current on all GPIO pins. Configurable 8 mA or 50 mA/pin current sink on designated pins

■ Each GPIO pin supports high impedance inputs, configurable pull up, open drain output, CMOS/TTL inputs, and CMOS output

■ Maskable interrupts on all I/O pins

BOM Savings
