ƒ General Description
KT0803M, our new generation of low cost Monolithic
Digital FM Transmitter, is designed to process high-fidelity
stereo audio signal and transmit modulated FM signal over
a short range. It’s based on the architecture of award-
winning KT0801 and it’s also an upgrade of KT0803. The
additional features added to KT0803M are increased
transmission power up to 113 dBuV, auto level detection
and bass boost.
The KT0803M features dual 20-bit ΔΣ audio ADCs, a
high-fidelity digital stereo audio processor and a fully
integrated radio frequency (RF) transmitter. An on-chip
low-drop-out regulator (LDO) allows the chip to be
integrated in a wide range of low-voltage battery-operated
systems with power supply ranging from 1.6V to 3.6V.
The KT0803M is configured as an I2C slave and
programmed through the industry standard 2-wire MCU
interface.
Thanks to its high integration level, the KT0803M is
mounted in a generic 16-pin SOP package. It only requires
a single low-voltage supply. No external tuning is required
that makes design-in effort minimum.

accessed during the last read or write operation, incremented by one. This address stays valid between
operations as long as the chip power is maintained.
Once the device address with the read/write select bit set to “1” is clocked in and acknowledged by the
KT0803M, the current address data word is serially clocked out. The microcontroller does not respond with
an input “0” but does generate a following stop condition (see Figure 4).

Figure 4: Serial Interface Protocol
Note: The serial controller supports slave mode only. Any register can be addressed randomly.
The address of the slave in the first 7 bits and the 8th bit tells whether the master is receiving data from the
slave or transmitting data to the slave. The I2C write address is 0x7C and the read address is 0x7D.
Slave Mode Protocol
With reference to the clocking scheme shown in Figure 5, the serial interface operates in the following
manner:
Figure 5: Serial Interface Slave Mode Protocol
CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an external device. Data
on the SDA pin may change only during SCL low time periods (see Figure 6). Data changes during SCL
high periods will indicate a start or stop condition as defined below.
START CONDITION: A high-to-low transition of SDA with SCL high is a start condition which must
precede any other command (see Figure 7).
STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. After a read
sequence, the stop command will place the KT0803M in a standby power mode (see Figure 7).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the KT0803M in 8-
bit words. The KT0803M sends a “0” to acknowledge that it has received each word. This happens during
the ninth clock cycle (see Figure 8).
