KT0936M(B9)

产品概述
The KT0936M is KT Micro’s 3rd generation of proprietary fully integrated mono full band FM/MW/SW receiver chip supporting mechanical tuning with embedded MCU. The new features include improved tuning feeling, working without EEPROM, tuning indicator, improved EMI/EMC, improved flatness of the sensitivity and the AM antenna can be placed more flexible.
 
Thanks to its advanced architecture, KT0936M offers an excellent user listening experience with high sensitivity, high signal-to-noise ratio, low distortion and low sensitivity to interference.
 
KT0936M provides direct and simple interface to support mechanical tuning. A pre-programmed low cost EEPROM can also be used to configure the radio settings to differentiate product designs and accommodate standards in various regions. No external MCU is required.
 
Thanks to its high integration level and efficient user interface design, KT0936M lowers the system cost, simplifies design and improves product reliability and manufacturability. KT0936M can operate with two AAA batteries, making it ideal for low-power portable radio.
