MAX66301-25x Evaluation Kit
Evaluates: MAX66301 and MAX66250
Detailed Description of Hardware
The MAX66301-25x EV system block diagram in Figure 5
is a functional representation. Starting from the left side,
the prolific device provides a virtual COM port to link the
PC to the MAXQ610 and is fully compatible with USB 2.0
specification. The MAXQ610 is preloaded with firmware
that either passes the UART protocol along or converts
the UART protocol to SPI with a SCLK at 2.667MHz.
The MAX66301 provides the RFID reader processing
per ISO 15693 and the secure coprocessor functionality
is based on FIPS 202-compliant standard. The AFE in
the MAX66301 drives a PCB antenna in a 100mW con-
figuration. Lastly, the MAX66250 is the tag in the system-
supporting authentication (i.e., clone prevention).
Jumpers and Switches
The MAX66301 EV kit has jumpers that allow configura -
tion options and contains switches for more configuration
options.
Table 1 and Figure 6 describe the MAX66301 EV kit and
the function of the jumpers. Default settings from Table 1 ,
in summary, support UART or SPI linking, USB power, and
3.3V operation.
