Product Specification
Digitally Controlled Impedance (DCI)
Active I/O Termination
• Optional series or parallel termination
• Temperature and voltage compensation
• Makes board layout much easier
− Reduces resistors
− Places termination in the ideal location, at the signal
source or destination
Configuration
• Support for platform Flash, standard SPI Flash, or
standard parallel NOR Flash configuration
• Bitstream support with dedicated fallback
reconfiguration logic
• 256-bit AES bitstream decryption provides intellectual
property security and prevents design copying
• Improved bitstream error detection/correction capability
• Auto bus width detection capability
• Partial Reconfiguration via ICAP port
Advanced Flip-Chip Packaging
• Pre-engineered packaging technology for proven
superior signal integrity
− Minimized inductive loops from signal to return
− Optimal signal-to-PWR/GND ratios
• Reduces SSO induced noise by up to 7x
• Pb-Free and standard packages
System Monitor
• On-Chip temperature measurement (±4°C)
• On-Chip power supply measurement (±1%)
• Easy to use, self-contained
− No design required for basic operation
− Autonomous monitoring of all on-chip sensors
− User programmable alarm thresholds for on-chip
sensors
• User accessible 10-bit 200kSPS ADC
− Automatic calibration of offset and gain error
− DNL = ±0.9 LSBs maximum
• Up to 17 external analog input channels supported
− 0V to 1V input range
− Monitor external sensors e.g., voltage, temperature
