The ML501 board has a 16-Mb SPI Flash (ST Microelectronics M25P16). The SPI Flash can
be used for FPGA configuration or to hold user data. The SPI Flash can be in-system
programmed using a Xilinx download cable.
Onboard temperature and voltage monitoring and control is handled by an Analog
Devices ADT7476A chip. This chip is controlled via IIC and can provide the following
functions:

Connector J31 is a keyed three-pin fan header similar to those found in computers. It is
designed to support a 5V DC fan. To bypass the fan controller chip and operate the fan at
full speed, the user can populate connector J32.
For high-power operating conditions, a heatsink and/or fan for the FPGA can be
accommodated on the board. The ML501 does not ship with a heatsink/fan unit but can
accommodate one (for example, Calgreg Electronics Smart-CLIP family of heatsink/fan
assemblies).
A piezo audio transducer is provided to allow simple beeps, tones, and songs to be played.
The piezo is driven by a transistor controlled by the FPGA.
The FMC connector (Rosenberger 16P101-40M L4) is a small, form-factor, surface mount,
50Ω coaxial connector suitable for high-frequency signal analysis.
The board has a pair of FMC connectors attached to 1.0V power supply. This permits the
user to perform spectrum analysis of the behavior of the power supply during board
operation. This can help the user tune the power supply decoupling network for optimal
performance. Because two FMC connectors are attached to the same power supply (on
opposite sides of the board), the user can use one FMC connector to inject a high frequency
signal into the power plane while the second FMC is connected to test equipment that
measures the response of the board.
By default, the FMC connectors are not soldered on. Contact Rosenberger of North
America (www.rosenbergerna.com) to order the FMC connector. Rosenberger also
manufactures adapter cables that allow SMA-based test equipment or cables to be
connected to the FMC connectors.
