Specifications of MAX6964EVKIT

• Product: Evaluation Kits

The MAX6964 EV kit features a jumper, JU2, for
configuring the MAX6964 2-wire serial address. The SCL,
SDA, and AD0 PCB pads are provided for interfacing to
the 2-wire serial address bus and configuring the
address, respectively. Table 2 lists the various jumper
options for configuring the 2-wire address.
The MAX6964 EV kit features a jumper to select the
MAX6964 IC BLINK pin source, either the EV kit’s oscil-
lator (U2 and U3) or a user-provided CMOS square-
wave signal. The square-wave signal is applied to the
EV kit’s BLINK_IN PCB pads. Table 3 lists the
various jumper options for the signal source.

*When using an external 2-wire serial interface, the shunt on jumper JU2 must be removed so the external 2-wire serial interface has
control of the MAX6964 AD0 pin.
*See Table 4 for configuring the oscillator frequency.

The MAX6964 EV kit features jumpers JU4 and JU5 to
set the EV kit’s oscillator frequency. The oscillator
frequency ranges from 0.7Hz to 3.0Hz. Additionally,
jumper JU6 is provided to disable the EV kit’s oscillator.
Table 4 lists the various frequency selection options for
jumper JU4. Table 5 lists jumper JU6 enable/disable
options for inverters U2 and U3.
The MAX6964 EV kit features a switch to reset the MAX6964
IC. Additionally, the EV kit provides a RST PCB pad for
using an external controller to reset the MAX6964 IC. Refer
to the MAX6964 IC data sheet for additional functions of the
MAX6964 RST pin. Table 6 lists the various switch and alter-
nate reset options for resetting the MAX6964 IC.
