AMI Semiconductor has announced two single-chip wireless transceivers, the AMIS-52150 and the AMIS-53050. These devices are optimized for sub-GHz, low-to-moderate data rate wireless communications in a variety of industrial applications that include building security and access, smoke and fire detection, building control and automation, lighting and utility metering. The operating frequency of the AMIS-53050 can be programmed from 300 MHz to 960 MHz, while enabling data rates up to 128 Kbps. The AMIS-52150 operates from 300 MHz to 768 MHz at data rates up to 16 Kbps. Both devices can be interfaced to a baseband processor via integrated I2C or SPI bus interfaces on the AMIS-53050, and an I2C interface on the AMIS-52150.
