resynchronization

 Optional LNA and/or PA

 Hardware accelerated AES and CCM* encryption with

 128-bit keys

 XAP5™ high performance 16/32-bit microcontroller

 4 Kbyte RAM, 64 Kbyte Program Memory

 Advanced Energy Management, supporting Energy

Harvester and battery operation

 UART, SPI or TWI serial interface

 ADC for two analog input channels and battery level

Low Cost

The GP490 is designed to operate on very low cost, single

layer, paper phenol like PCB material using only low cost

components and printed circuit antennas. No expensive

shielding, chip antennas or voltage regulators are required to

design a wireless harvesting control device. The integrated

microcontroller,

program

memory,

Real-Time

MAC

and

harvesting power management allow for a fully integrated,

single chip approach.

Ultra-Low Power, Maintenance Free

The GP490 is designed for ultra-low power consumption and

can run on a coin-cell battery for up to 10 years, essentially

removing the need for battery replacement. The energy

generated by a harvester is enough to send multiple packages

on the generated energy, allowing for a battery free solution.

Advanced Integrated Energy Management

The GP490 has an advanced integrated energy management

system, which allows it to operate from a standard lithium coin-

cell battery as well as from intermittent power supplies like

photovoltaic (solar), electro-mechanical and piezoelectric, with

a minimum of additional components. The energy management

system includes ultra-low power voltage level detectors and

overvoltage protection circuitry, allowing safe operation and

graceful shutdown. The battery lifetime monitor tracks the

usage of the battery and provides an early exhaustion warning.

Excellent Range and Reliability

The

Qorvo

radios

have

been

optimized

for

reliable

communication in harsh radio environments. The GP490, in

combination with other Qorvo products, provides robust and

reliable link quality. The high receiver sensitivity on Qorvo

products in combination with the built-in antenna diversity and

Qorvo

’s unique receiver technology provides excellent range

and reliability. 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 the combination of

excellent receiver dynamic range and an auto tuned band-pass

filter.
