Today, we make a good thing even better. Silicon Labs’ new EZRadio and EZRadioPRO families offer the highest levels of RF performance and single-chip integration in the sub-GHz wireless IC market. These sub-GHz wireless ICs provide support for 802.15.4 and WMBus and have long-range capabilities.
Ideally suited for battery-powered wireless applications, the EZRadio and EZRadioPRO devices provide the industry’s lowest standby current with memory retention, consuming up to 75 percent less sleep mode current than competing solutions. Each device includes a patent-pending signal arrival detector that reduces the average receiver current by detecting a signal faster than traditional sub-GHz receivers, effectively increasing the battery life for various applications.
These energy-friendly sub-GHz radios can operate on a single coin cell battery, and they are well suited for smart meter designs that require long-range and up to 20-year battery lifetime. Autonomous duty cycling between active and low-power modes and advanced features such as frequency hopping and antenna diversity minimize host MCU interaction and further reduce overall system power consumption.
Silicon Labs’ sub-GHz radios support a wide variety of proprietary protocols through flexible on-chip packet handler and modem technology. EZRadio devices handle most basic packet formats, while EZRadioPRO devices are designed for more complex packet formats. The flexible architecture offloads the host microcontroller (MCU) without sacrificing RF performance. EZRadio and EZRadioPRO devices can support a protocol stack such as an 802.15.4-based mesh network or a point-to-point or star network in conjunction with a Silicon Labs 8-bit MCU or a 32-bit EFM32® Gecko MCU as the external host.
Si4x55 EZRadio transceivers, transmitters and receivers provide cost-effective, easy-to-use wireless connectivity solutions for basic “push-button” applications such as remote controls for set-top boxes, bidirectional key fobs and garage door openers.
Si4x6x EZRadioPRO transceivers, transmitters and receivers are an excellent choice for developers requiring advanced features, higher RF performance and a wider range of protocol options. They are ideal for ultra-long-range, narrow-band applications using complex, advanced packet formats and network protocols.
