Datasheet - Application Information
9.4 8x8 LED Dot Matrix Driver
The application example in
Figure14
shows the AS1106 as an 8x8 LED dot matrix driver.
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 Table7 on page9.
The Decode Enable Register (see page 10) must be set to ‘00000000’ as described in Table9 on page10. Single LEDs in a column can be
addressed as described in Table12 on page11, where bit D0 corresponds to segment G and bit D7 corresponds to segment DP.
Note:
For a multiple-digit dot matrix, multiple AS1106 devices must be cascaded.
Figure 14. Application Example as LED Dot Matrix Driver
9.5 Cascading Drivers
The example in
Figure14
drives 2 dot matrix digits using a 4-wire mcroprocessor interface. All Scan-Limt Registers should be set to the same
value so that one display will not appear brighter than the other.
For example, to display 12 digits, set both Scan-Limt Registers to display 6 digits so that both displays have a 1/6 duty cycle per digit. If 11 digits
are needed, set both Scan-Limt Registers to display 6 digits and leave one digit unconnected. Otherwise, if one driver is set to display 6 digits
and the other to display 5 digits
one display will appear brighter because its duty cycle per digit will be 1/5 and the other display’s duty cycle will
be 1/6.

No-Op Register (0xX0) on page 13
