09 PIN ASSIGNMENT IK2102 PIN LIST AND DESCRIPTIONS Pin Name RCUR DI/O CLK STB K1, K2 VDD SG1/KS1 to SG10/KS10 SG11/GR7 to SG13/GR5 GND GR4 to GR1 I/O Description Pin № A resistor is connected to this pin to determine the I SG1-SG13 output current and internal oscillation frequency.
Data Input - Output Pin This pin inputs serial data at the rising edge of the I/O clock (starting from the bit).
Data Output Pin - N-Channel, Open-Drain This pin outputs serial data at the falling edge of the clock.
Clock Input Pin I This pin reads serial data at the rising edge and output data at the falling edge.
Serial Interface Strobe Pin I The data input after the STB has fallen is processed.
When this pin is HIGH, CLK is ignored.
Key Data Input Pins I The data sent to these pins are latched at the end of the display cycle.
(Internal Pull-Low Resistor).
