ETK6201
LED Controller/Driver
DESCRIPTION
ETK6201 is an LED Controller driven on a 1/7 to 1/8 duty factor. 11 segment output lines, 6 grid output lines,
1 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 ETK6201 via
a four-line serial interface. Housed in a 32-pin SOP Package, ETK6201 pin assignments and application circuit are
optimized for easy PCB Layout and cost saving advantages.
FEATURES

Command 3Address Setting Commands
Address Setting Commands are used to set the address of the display memory. The address is considered
valid if it has a value of 00H to 0DH. If the address is set to 0EH or higher, the data is ignored until a valid
address is set. When power is turned ON, the address is set at 00H.
