• Hardware design updates or modifications to products already in the field via unlimited reprogrammability
• Shortening design and development cycles for complex, high-density applications

Field Programmable Gate Array Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm the voltage domain requirements align with the 3.0V to 3.6V operating specification for the XC4000L family. Ensure compatibility with existing design environments and configuration bitstreams intended for the XC4000E series.

Field Programmable Gate Array Selection Notes

Select this device when low-power consumption is critical compared to standard 5V devices. The XC4000L offers identical functionality to the XC4000E except for timing, power, and current-sinking capability differences. Consider the 4 mA sink current per output characteristic when designing interface circuits. Verify that the 66 MHz performance meets the target system clock rate requirements.

Field Programmable Gate Array Part Context

This component belongs to the XC4000-Series, which combines architectural versatility with increased speed and routing resources. The XC4000L represents the low-voltage version of the XC4000E devices. These FPGAs provide custom CMOS VLSI benefits while avoiding initial costs and long development cycles associated with conventional masked gate arrays.

Field Programmable Gate Array FAQ

How does the XC4000L differ electrically from the XC4000E?

The XC4000L functions at 3.0V to 3.6V and provides 4 mA sink current per output, whereas the XC4000E typically operates at 5V and provides 12 mA sink current.

Is the XC4005L backward compatible with older XC4000 devices?

Yes, any XC4000E device, including the XC4000L, is pinout- and bitstream-compatible with the corresponding original XC4000 device.

What memory configurations are supported by the CLBs?

The RAM in any CLB can be configured as level-sensitive single-port, edge-triggered single-port, or edge-triggered dual-port RAM.
