MAX1067/MAX1068
Digital Interface
The MAX1067/MAX1068 feature an SPI/QSPI/
MICROWIRE-compatible 3-wire serial interface. The
MAX1067 digital interface consists of digital inputs CS,
SCLK, and DIN; and outputs DOUT and EOC. The
MAX1067 operates in the following modes:
SPI interface with external clock
SPI interface with internal clock
SPI interface with internal clock and scan mode
In addition to the standard 3-wire serial interface modes,
the MAX1068 includes a DSPR input and a DSPX output
for communicating with DSPs in external clock mode
and a DSEL input to determine 8-bit-wide or 16-bit-wide
data-transfer mode. When not using the MAX1068 in the
DSP interface mode, connect DSPR to DVDD and leave
DSPX unconnected.
Command/Configuration/Control Register
Table 1 shows the contents of the command/configura-
tion/control register and the state of each bit after initial
power-up. Tables 2–6 define the control and configura-
tion of the device for each bit. Cycling the power sup-
plies resets the command/configuration/control register
to the power-on-reset default state.
Initialization After Power-Up
A logic high on CS places the MAX1067/MAX1068 in the
shutdown mode chosen by the power-down bits, and
places DOUT in a high-impedance state. Drive CS low to
power-up and enable the MAX1067/MAX1068 before
starting a conversion. In internal reference mode, allow
5ms for the shutdown internal reference and/or buffer to
wake and stabilize before starting a conversion. In exter-
nal reference mode (or if the internal reference is already
on), no reference settling time is needed after power-up.
