Key Features

• IEEE 802.15.4 compliant PHY and Real-Time MAC

• Operates in the worldwide 2.4 GHz ISM-band

• Excellent range by antenna diversity: 8 dB more reliable

link budget compared to single antenna

• Additional robustness by packet-in-packet

resynchronization

• 30 dB better robustness to Wi-Fi Interference

• External PA signals for extended range

• Hardware accelerated AES and CCM* encryption with

128, 192 and 256-bit keys

• 8 Kbyte RAM for data buffering

• Extremely low standby power consumption

• External Controller SPI Slave interface

• Stand-alone RF4CE DutyCycling support and RF4CE

packet filtering when the host is asleep

• Coexistence Interface with other radios in the device

Excellent Range and Reliability

The GP502 has been optimized for reliable communication in

harsh radio environments. The excellent receiver sensitivity and

high transmit power allow extended coverage. Built-in antenna

diversity with two antennas improves the reliable link budget by

8 dB resulting in approximately twice the reliable range

compared to similar systems with only one antenna. In high

density networks the packet-in-packet resynchronization further

improves the communication reliability. The potential risks of

interference by Wi-Fi and/or Bluetooth devices have been

reduced by an excellent receiver interference rejection

capability and dynamic adaption of the frequency channel.

The Coexistence Interface can be used to enable coexistence

of the IEEE 802.15.4 radio of the GP502 with other potentially

interfering radios (Wi-Fi, Bluetooth) within the same device.

Ultra-Low Power Consumption

The

GP502

is

designed

for

ultra-low

power

network

applications. It supports RF4CE duty cycling and can wake up

the host when a specified message has been received, with

RF4CE Network

layer and Profile layer Deep Packet

Inspection, to allow the host to stay asleep as much as possible.

Low Cost

The GP502 is designed to operate on PCB designs using only

low-cost

components

and printed circuit antennas.

No

expensive shielding, chip antennas or voltage regulators are

required.
