 Description

The KT0932M is KT Micro’s latest generation of

proprietary fully integrated AM/FM receiver chip

supporting mechanical tuning without MCU. The new

features include improved tuning feel, new Tuning light

signal, improved EMI/EMC, improved FM flatness of

sensitivity.

Thanks to its advanced architecture, KT0932M offers an

excellent user listening experience with high sensitivity,

high signal-to-noise ratio, low distortion and low sensitivity

to interference.

KT0932M provides direct and simple interface to support

mechanical tuning. A pre-programmed low cost EEPROM

can 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, KT0932M lowers the system cost,

simplifies design and improves product reliability and

manufacturability. KT0932M can operate with two AAA

batteries, making it ideal for low-power portable radio.
