FUNCTION DESCRIPTION
(1) Oscillation
The SM5025A/B oscillation circuit is designed for use of a 400 kHz or 500 kHz ceramic
resonator, but there may be mutual influence between variations in the IC and ceramic
resonator resulting in abnor mal oscillation. The oscillation circuit starts to operate when a
key is depressed.

(2) Key Scan
A pull-down resistor is inserte d between the key input pins and the VSS pin. If two or more
keys are depressed simultaneously, transmission is disabled by the multi-depression
prevention circuit. When a key is depressed, reading of the custom co de and key data code
is started, and DOUT output begins 36 ms later, so that if t he key is being depressed during
this 36 ms interval one transmission is performed. If a key is held down for 108 ms or long er,
consecutive transmissions of the leader code only are performed while the key is depressed.
Key Input
Ex. f OSC = 455 kHz
MIN. 36 ms
58.5 to 76.5 ms
108 ms
108 ms
(3) Data Code D7 Control
Data code D7 can be controlled by this pin, allowing 128 kinds of data to be transmitted.
D7 is set to "0" by connecting the SEL pin to VDD, and to "1" by connecting the SEL pin to
VSS . As the input of this pin is high-impedance, it must be connected to either V DD or VSS.

TRANSMISSION CODE
(1) DOUT Output
The transmission code consists of a leader code, 16-bit custom code, and 8-bit data code.
The inverse code of the data code is also sent simultaneously, giving a total configuration
of 32 bits per transmission.

The leader code consists of a 9 ms carrier waveform plus a 4.5 ms OFF waveform, and is
used as the leader for the following code. The code uses the PPM (Pulse Position
Modulation) method, with "1" and "0" differentiated by the time bet ween pulses reference

(2) Custom Code Extension
The custom code can be set by the diodes connected to the CODE pin and the KI/O pins.
Connecting the CODE pin and KI/O pins via diodes gives a corresponding custom code of "1",
while no connection gives "0".
The above output codes can be obtained by custom code selection using diodes only. To
further extend the number of custom codes, 200 kΩ pull up resi stors are added to pins KI/O0
through KI/O7, and the bit corresponding to a pin from among the custom code' outputs is
output without being inverted.

(3) Custom Code
The DOUT output custom code can be set in any of 65536 ways by means of the diodes
attached to the CODE (Custom Code Select) pin and the KI/O pins and the pull-up
resistors attached to the KI/O pins. When a code other than code 00000000 (no diode
connection) is used.
(4) Custom Code Mask ROM Specification
The custom code can also be set by mask ROM. When the mask ROM specification is
used the custom code can be set without th e connection of external diodes and resistors,
and by combining external diodes and resistors with mask ROM it is possible to output a
code with different contents from those set by the mask ROM. W hen mask ROM
specification is used, (Ver. I) or (Ver. II) can be selected.

(Ver. I)
Internal custom code ROM1 and ROM2 (total 16 bits) are effecitve, with 8 bits being the part
(ROM1) corresponding to the external diodes, and 8 bits the part (ROM2) corresponding to the
external pull-up resistors.
(Ver. II)
W ith Ver. II, the CODE pin does not have the function of reading the external diodes.
Internal custom code ROM2 and ROM3 (total 28 bits) are effective, with 20 bits being the part
(ROM3) for setting the 4 channels of custom code C7, C6, C5, C4 and C3 as 5 bits each, and 8
bits being the part (ROM2) corresponding to the external pull-up re sistors (excluding KI/O6 and
KI/O7). With Ver . II 0/1 allocation to C2, C1 and C0 of the custom code high-order bits is set

DOUBLE KEY OPERATION
When more than two keys except K21 + K22, K21 +K23 and K21 +K24 are depressed at the
same time, the transmission output stops.
Double key operation is useful for tape deck recording operation.

When a user selects Ver. 1, ROM1 is available for the customer code (C 7 to C0) selection.
ROM2 is available for the customer code' (C 7' to C0') selection.
When a user selects Ver. 2, ROM3 is available for the customer code (C 7 to C3) selection.
And a user can select ROM3-0, ROM3-1, ROM3-2 or ROM3-3 by the KI/O 6 and KI/O7 pull
up resistances.
