Maxim EV systems whose ordering number ends in
EVCMAXQU are two-board sets, comprising a
CMAXQUSB interface board and an EV kit board specif-
ic to the device being evaluated. For example, the
MAX6870EVCMAXQU would be a two-board set consist-
ing of the MAX6870EVKIT and the CMAXQUSB. The fol-
lowing generic quick start procedure assumes that the
CMAXQUSB board will be used with a companion EV kit.

The low-voltage RISC microcontroller, MAXQ2000-RAX
(U1), processes commands sent by a program running
on the PC. Each particular EV kit has its own custom
software specific to that kit.
The FTDI FT232BM (U2) provides the USB engine. The
USB 5V power is regulated down to 3.3V by U11 and
down to 2.5V by U3. LED1 indicates USB 5V power is pre-
sent. LED2, LED3, LED4 are general-purpose indicators.
Level translators U6–U10 convert the MAXQ2000’s
2.5V logic signals to the external VDD logic level, which
is jumper-selectable for 2.5V, 3.3V, or 5V logic. U9, the
MAX3372, is a bidirectional level translator specially
