The KT0853 is KT Micro’s 2^nd generation of proprietary fully integrated FM receiver chip that upgrades the performance, improve the user experience and ease integration and manufacturing efforts. The new features includes the additional audio input, independent status indicator, improved EMI/EMC and higher FM stereo separation.
 
Thanks to the patented tuning technology, the receiver maintains good signal reception even with short antennas. The chip consumes merely 25mA current and can be powered by 2 AAA batteries. Another useful feature is that the volume and channel information can be preserved in standby mode without external memories. KT0853 supports a wide range of reference clocks from 32.768KHz to 26MHz, hence can share system clocks with a varieties of MCUs further reducing the system BOM cost. The KT0853 have different user interface schemes like other parts in the KT085x family,
 
With high audio performance, fully integrated features and low BOM cost, KT0853 is ideal for various applications and products that require flexible programmability for rich features
