KKA3010
INFRARED REMOTE CONTROL
TRANSMITTER RC-5
The KKA3010 is intended as a general purpose (RC-5) infrared
remote control system for use where a low voltage supply and a large
debounce time are expected. The device can generate 2048 different
commands and utilizes a keyboard with a single pole switch for each key.
The command are arranged so that 32 systems can be addressed, each
system containing 64 different commands. The keyboard interconnection
is illustrated by Fig.1.

FUNCTIONAL DESCRIPTION
Keyboard operation
Every connection of one X-input and one DR-output will be recognized as a legal key operation and will cause the
device to generate the corresponding code. The same applies to every connection of one Z-input to one DR-output with
the proviso that SSM must be LOW. When SSM is HIGH a wired connection must exist between a Z-input and DR-
output. If no connection is present the system number will not be generated. Activating two or more X-inputs, Z-inputs
or Z-inputs and X-inputs at the same time is an illegal action and inhibits further activity (oscillator will not start).
When one X- or Z-input is connected to more than one DR-output, the last scan signal will be considered as legal.
The maximum value of the contact series resistance of the switched keyboard is 7KΩ.
Inputs
In the quiescent state the command inputs X0 to X7 are held HIGH by an internal pull-up transistor. When the system
mode selection (SSM) input is LOW and the system is quiescent, the system inputs Z0 to Z3 are also held HIGH by an
internal pull-up transistor. When SSM is HIGH the pull-up transistor for the Z-inputs is switched off, in order to
prevent current flow, and a wired connection in the Z-DR matrix provides the system number.
Outputs
The output signal DATA transmits the generated information in accordance with the format illustrated by Fig.2 and
Tables 1 and 2. The code is transmitted using a biphase technique as illustrated by Fig.3. The code consists of four
parts:
•
•
•
•
Start part - 1.5 bits (2 x logic 1)
Control part - 1 bit
System part - 5 bits
Command part - 6 bits
The output signal MDATA transmits the generated information modulated by 1/12 of the oscillator frequency with a
50% duty factor.
In the quiescent state both DATA and MDATA are non-conducting (3-state outputs).
The scan driver outputs DR0 to DR7 are open drain n-channel transistors and conduct when the circuit is quiescent.
After a legal key operation the scanning cycle is started and the outputs switched to the conductive state one by one.
The DR-outputs were switched off at the end of the preceding debounce cycle.

Operating Temperature, All Package Types
This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
V
OUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
