SOP28

3V to 5.5V input voltage

Multiple Display Modes: ( 11x6 / 8x7 / 9x7 / 10x7 )

Key Scanning ( 10 x 2 matrix )

8-Steps Dimming Circuitry ( 1/16 to 14/16 duty factor )

Simple Serial Interface: CLK / DIN / DOUT / STB

Low Power Consumption

The BCT72323S is an LED Display and Keyboard Controller with 8-steps digital dimming control. Ten segment output lines, seven grid output lines, one display memory ( 14 bytes ), control circuit, key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for use together with the main microcontroller.

Control and data are easily communicated to BCT72323S via a fourwire serial interface ( DIN, STB, CLK and DOUT ).
