ETK6203
LED Controller/Driver
Description
ETK6203 is an LED Controller/driven on a 1/5 to 1/8 duty factor. 11 segment output lines, 4 grid output
lines, 3 segment/grid output lines, one display memory, control circuit, key scan circuit are all incorporated into a
single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to
ETK6203 via a four-line serial interface. Housed in a 30 pins TSSOP, ETK6203 pin assignments and application
circuit are optimized for easy PCB Layout and cost saving advantages.

Functional Description
COMMANDS
A command is the first byte (b0 to b7) inputted to ETK6203 via the DIN Pin after STB Pin has changed from
HIGH to LOW State. If for some reason the STB Pin is set to HIGH while data or commands are being
transmitted, the serial communication is initialized, and the data/commands being transmitted are considered
invalid.
Command 1：Display Mode Setting Commands
ETK6203 provides 4 display mode settings as shown in the diagram below: As started earlier a command is
the first one byte (b0 to b7) transmitted to ETK6203 via the DIN Pin when STB is LOW. However, for these
commands, the bit3 & bit8 (b2 to b7) are given a value of 0.
The Display Mode Setting Commands determine the number of segments and grids to be used (14 to 11
segments, 4 to 7 grids). A display command ON must be excited in order to resume display. If the same mode
setting is selected, no command execution is take place, therefore, nothing happens.
