Field Programmable Gate Array Procurement Notes

Verify the specific suffix code against official Microsemi documentation to confirm package type and temperature rating. Confirm current availability status as many ACT™ 2 devices are discontinued or end-of-life. Ensure compatibility with existing programming tools and antifuse configuration requirements before procurement.

Field Programmable Gate Array Selection Notes

Select this component when a high gate count FPGA is required in an 84-pin PLCC package. Consider the 75 MHz performance limit and 5 V operating voltage. Evaluate if the ACT™ 2 architecture meets timing constraints compared to newer families. Verify that the JTAG boundary scan support aligns with testing infrastructure needs.

Field Programmable Gate Array Part Context

The A1240A-PL84C is part of the ACT™ 2 series, which offers significant logic density improvements over earlier ACT™ 1 devices. This series is characterized by its antifuse technology, providing non-volatile configuration without the need for external memory. The PL84 variant specifically denotes the plastic leaded chip carrier package suitable for surface mount applications.
