Datasheet

The firmware allows for immediate interfacing to the hardware, for collection and saving of samples. Figure 2b
shows the simple process flow. The firmware is in C, developed using the Xilinx SDK tool, based on the Eclipse
™
open source standard. Custom Fremont-specific design functions (driver in the maximDeviceSpecificUtilities.c
file) were created utilizing the AXI MAX11100 custom IP core. The SPI clock frequency is 4.54MHz when the
sample rate is 189.4ksps. The SPI clock frequency is set to 2.5MHz for all other sampling rate.

The firmware accepts commands, writes status, and can download blocks of sampled data to a standard terminal
program over a virtual COM port. The complete source code speeds customer development. Code
documentation resides in the corresponding firmware platform files.
