TECHNICAL DATA
LD1207
DESCRIPTION
The LD1207 is specifically designed for LED and LED DISPLAY derivers.
The LD1207 have 12/9 segment output lines, 7 to 4 grid output lines, one display memory, control circuit
and 3 line serial data interface.
This function are all incorporated into a single chip to build a highly reliable peripheral
device for a single chip microcomputer. It is very convenience to control for numeric display.
LD1207’s pin assignments and application circuit are optimized for easy PCB Layout and cost saving
advantages.

Description
Oscillator Input Pin.
A resistor is connected to this pin and GND.
Data Input Pin.
This pin inputs serial data at the rising edge of
the shift clock (staring from the lower bit)
Clock Input Pin.
Rising edge trigger.
Strobe pin for Serial Interface.
The data input after the STB has fallen is
processed as a command.
When this pin is “HIGH”, CLK is ignored.

COMMAND 3 : ADDRESS 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”.
Please refer to the diagram below.
