Product Overview

The GP490 ZigBee Home Automation Communications Controller is a System-on-Chip that

provides a fully integrated solution for ultra-low power wireless communications for ZigBee

Smart Home end node applications. It is compliant with the IEEE Standard 802.15.4, providing

robust spread spectrum data communication with a secure encrypted data flow.

The GP490 features a radio transceiver, integrated real-time Medium Access Control

processor, integrated microcontroller, security engine, event scheduler, advanced power

management features, memory and an extensive set of peripherals. The integrated RF filtering

simplifies the RF design complexity enabling very low cost single layer applications using

simple PCB antennas requiring no shielding and a minimum number of external components.

Advanced power management features ensure that power consumption is minimized in both

active and standby states.

The GP490 application layer is programmable. It can communicate with external peripherals via UART, SPI, TWI or direct signal

interfaces.
