• Flexible sysIO buffers supporting diverse interface standards such as LVCMOS, LVTTL, PCI, and LVDS

Field Programmable Gate Array Applications

• Glue logic implementation for system integration
• Bus bridging and bus interfacing tasks
• Power-up control and general control logic management

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix '4' against the official datasheet timing specifications to ensure compliance with target clock frequencies. Confirm that the 100-pin TQFP package dimensions align with the PCB footprint requirements. Ensure design tools support the MachXO family for proper synthesis and place-and-route operations.

Field Programmable Gate Array Selection Notes

Select this model for applications requiring low-density logic with high I/O flexibility. The E variant supports a wide voltage range from 1.2V to 3.3V, offering compatibility with various system power rails. Consider the 100-pin TQFP package for surface-mount assembly needs where moderate pin counts are sufficient.

Field Programmable Gate Array Part Context
