EZRadio® ISM Band ICs

Silicon Labs EZRadio® family of fully integrated, low-power, low-data-rate, cost-effective wireless ICs are designed to meet the needs of OEMs developing ISM applications for the consumer, industrial and automotive markets. The EZRadio ISM band receivers and transmitters target one-way wireless link applications such as remote keyless entry (RKE), garage door openers, remote controls, home automation, and security devices. Silicon Labs has expanded its EZRadio family of ISM Band ICs with a new Sub-GHz Receiver (Si4355), Transceiver (Si4455), and development kits.
