1C DESCRIPTION
1C, TC9297F
Pin No. Pin Name I/O Description
1 -4 K1 -K 4 I
Key scan inputs. A maximum of 6x5=30 key data can be input with a matrix of key
scan outputs TO - T5. When "H " is applied to this pin, scanning of keys w ill start.
These pins incorporate pull-down resistors.
5 -1 0 T 0 -T 5 0Key scan timing outputs. Since a load resistor RON is built into the N-ch to form a key
matrix, a diode is not necessary. In normal operation, these pins output "H ", and when
"H " is applied to key scan inputs K0 ~ K4, key scanning w ill start.
11 COM1 O LC D common signal outputs. When 1/2 duty is set, matrixing of COM1, 2 and
SO - S39 allows the display of up to 80 segments. When 1/3 duty is set, matrixing of
COM1-3 and S I ~ S39 allows display of up to 117 segments.In the 1/3 duty mode, the
SO pin is used as a COM3 pin.
12 COM2 O
13 SO/COM3 O
14-48 S I ~ S35 oLC D segment signal outputs. When 1/2 duty is set, matrixing of COM1, 2 and
SO - S39 allows display of up to 80 segments. When 1/3 duty is set, matrixing of
COM1-3 and S I - S39 allows display of up to 117 segments. S36 - S39 are commonly
used for L ED drivers. The LED driver outputs become N-ch open drain outputs, and
the LED s can be directly indicated since they are driven by high current.
49-52 S36/OT3 - S39/OTO 0
53 GND —GND
54 OSC —
C and R which are attached externally form an oscillator.
The oscillation frequency is shown by the following formula:
fosc = 1.5/(C • R [H z]
For example, when C = 0.01 ¡x F and R = 30 k fl ,
fosc =? 5 kHz.
55 VD D
Power supply input. Normally, a voltage V R ST - 5.5 V is applied. This pin is provided
with a power-on reset function: the system reset w ill function when power is turned on
or VDD is less than 3 V (standard .
56 RST 1
Device system reset signal input. When RST input is "L ", the oscillator w ill stop, all
internal data w ill be reset and the LC D output pins and key scan output pins w ill be
fixed at "H ". For normal operation, connect this pin to VDD , since the device
incorporates a power-on reset circuit.
57 C K ISerial interface pins. The device communicates the display data, key input data and the
data which controls these with the controller. When the C E pin is "L", data w ill not be
communicated. When it goes "H ", data w ill be communicated between the D ATA pin
and controller, synchronized with the clock signal input to the C K input pin. A ll these
pins have Schmitt input circuits.
58 D A TA I/O
59 C E I
60 K0 I
Key scan input. A maximum of 6x5=30 key data can be input with a matrix of key
scan outputs TO ~ T5. When "H " is applied to this pin, scanning of keys w ill start. This
pin incorporates a pull-down resistor.
