• Manufacturer Part Number: MAX6960
• Description: 4-Wire Serially Interfaced 8 x 8 Matrix Graphic LED Drivers
• Manufacturer: MAXIM [Maxim Integrated Products]

Table 12. Power-Up Configuration
*When reading from the global registers, only the master MAX6960 (whose driver address is 0x00) responds.
Table 13. Global Driver Devices Format
Table 14. Global Driver Rows Format
On power-up, all control registers are reset (Table 12),
and the MAX6960 defaults to driver address 0 within a
panel of 256 drivers, monocolor, 1-bit-per-pixel, in one
row. The 3-wire interface automatically performs a con-
figuration on all interconnected MAX6960s after power-
up, reassigning the driver address allocation according
to the 3-wire interface interconnections. After perform-
ing the driver address allocation, the MAX6960 enters
shutdown mode.

The MAX6960s driving a display panel must be config-
ured before the panel can be used to display images.
The configuration involves the global panel configura-
tion register (Table 15–Table 22), the global driver
devices register (Table 13), and the global driver rows
register (Table 14).
