3.3.9 Communication and Configuration
The MAX1000 board uses a single chip to perform configuration of the device and USB to UART
communications, having each described below.
3.3.9.1 UART Communication
UART to USB communication supports USB 2.0 High Speed (up to 480 Mb/s) independently of
other protocols used in the chip like JTAG. Below is the connection schematic and pinning
information.
3.3.9.2 JTAG Chain Configuration
There are two types of configuration methods supported by MAX1000:
1. JTAG Configuration: configuration using JTAG ports. JTAG configuration scheme allows you to
directly configure the device core through JTAG pins (TDI, TDO, TMS and TCK pins). The
Quartus Prime software automatically generates a .sof that can be downloaded to the MAX10
with a download cable through the Quartus Prime Programmer.
2. Internal Configuration: configuration using internal flash. Before internal configuration, you
need to program the configuration data .pof into the configuration flash memory (CFM) which
provides non-volatile storage for the bit stream. The information is retained within CFM even
if the MAX1000 is turned off. When the board is powered on, the configuration data in the
CFM is automatically loaded into the MAX10 FPGA.
