Description
Serial-Data I/O . Open drain digital I/O I2C data pin.
Digit Drive Lines . Eight digit drive lines that sink current from the display
common cathode. Keyscan detection optional, but must be polled by the
μProzessor.
Ground .
Keyscan Input. Keyscan lines for key readback. Can be used for self-adressing.
Reset Input. Pull this pin to low to resest all registers (set to default values) and
to put the device into shutdown. Connect this pin via a pull-up resistor to V DD for
normal operation.
Set Segment Current . Connect to V DD or a reference voltage through R SET to
set the peak segment current (see Selecting RSET Resistor Value and Using
External Drivers on page 19 ).
Serial-Clock Input . 3.4MHz maximum rate.
Interupt Request Output . Open drain pin.
Seven Segment and Decimal Point Drive Lines . 8 seven-segment drives and
decimal point drive that source current to the display.
Positive Supply Voltage . Connect to +2.7V to +5.5V supply. Bypass this pin to
GND with a 0.1μF capacitor to avoid power supply ripple.
Exposed Pad. This pin also functions as a heat sink. Solder it to a large pad or to
the circuit-board ground plane to maximize power dissipation.
