Lattice Semiconductor
Compact Flash Connector
Connector J14 provides the evaluation board with the ability to interface to 3.3V Type II Compact Flash devices.
The FPGA can be programmed to use the various different Compact Flash protocols.

Mixed Signal Support
The LatticeXP2 Standard Evaluation Board also provides access to some mixed signal interface chips. There are
four primary components dedicated to performing mixed signal functions on the evaluation board. These compo-
nents are:
• 12-bit Analog to Digital Converter
• 12-bit Digital to Analog Converter
• 128-position Digital Potentiometer
• 25K ohm Discrete Potentiometer
The mixed signal devices are all powered from the 3.3V supply. The digital power for these devices comes directly
from the 3.3V plane layer. The analog power is supplied via a smaller independent 3.3V plane. The independent
plane is supplied from the 3.3V digital plane, but it is filtered with a ferrite bead.
Analog to Digital Converter
The board includes a Burr Brown ADS7842 4 Channel Parallel Sampling Analog to Digital converter.
