Field Programmable Gate Array Procurement Notes

Verify the specific suffix '1' indicates the speed grade corresponding to the 310 MHz maximum operating frequency. Confirm the package designation matches the 256-pin FBGA form factor required for the target PCB layout. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly. Check for any export control classifications such as ECCN 3A991D that may impact international shipping logistics.

Field Programmable Gate Array Selection Notes

Select this model when a balance of moderate logic capacity and high-speed performance is needed in a compact footprint. The 178 I/O count suits applications requiring extensive peripheral connectivity. Consider the 1.5 V core voltage requirement for power budgeting. Compare against the A3P400-2FGG256I if higher speed grades are necessary, or the A3P060 if lower gate counts suffice.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 family, which bridges the gap between ASICs and SRAM-based FPGAs. It offers the reprogrammability of FPGAs with the non-volatility and low static power consumption typical of ASICs. The family is designed for cost-sensitive applications requiring high volume production and long-term availability.

Field Programmable Gate Array Replacement Considerations

The A3P400-2FGG256I serves as a pin-compatible alternative offering a higher speed grade. Designers should verify timing constraints before substituting faster variants. No direct drop-in replacements exist outside the ProASIC3 family due to unique architectural differences.
