VDD: +5V ± 0.5V
Input
VSS: 0V
Input VPP: VDD - 35V
Applies voltage to pull-down resistor SEG0-7 and DGT0-7.
Input Oscillation input terminal
Oscillation output terminal
To OSCI in case of clock input from outside by separately excited
oscillation.
Input L: Serial input permitted
H: Serial input prohibited
Input Clock input for serial transfer
Input Serial data input:
Command data, address data, indication data, control register
data or port output data is input.
Output Serial data output:
Key scan input data or port input data is output.
5 bits.
Can be switched to key scan input, general-purpose input or
general-purpose output by bit unit.
The pull-down resistor is between VSS terminals.
General-purpose output: high current output for driving LED
Output 8-bit high tension output port. (Segment output)
Output type is Pch open drain, and pull-down resistor is built in
between VPP terminals.
Output 4-bit high tension output port.
Can be switched to general-purpose output/segment output by bit
unit. Output type is Pch open drain.
4-bit high tension output port.
Can be switched to general-purpose input/general-purpose output/
segment output/digit output by bit unit.
Output type is Pch open drain.
High current output for driving LED
Output 4-bit high tension output port.
Can be switched to general-purpose output/digit output by bit unit.
Output type is Pch open drain.
Output 8-bit high tension output port. (Digit output)
Output type is Pch open drain, and pull-down resistor is built in
between VPP terminals.
