8x8 Dot Matrix Mode
The application example in
The LED columns have common cathodes and are connected to the DIG0:7 outputs. The rows are connected to the
segment drivers. Each of the 64 LEDs can be addressed separately. The columns are selected via the digits as listed
in
The Decode Enable Register
LEDs in a column can be addressed as described in
bit D7 corresponds to segment DP.
Note: For a multiple-digit dot matrix, multiple AS1116 devices can be cascaded easily.
Figure 20. Application Example as LED Dot Matrix Driver
Supply Bypassing and Wiring
In order to achieve optimal performance the AS1116 should be placed very close to the LED display to minimize effects
of electromagnetic interference and wiring inductance.
Furthermore, it is recommended to connect a 10µF electrolytic and a 0.1µF ceramic capacitor between pins V
GND to avoid power supply ripple
