A3P125-2TQG144

Field Programmable Gate Array Overview

The A3P125-2TQG144 is a field-programmable gate array (FPGA) from Microchip's ProASIC3 family, housed in a 144-pin TQFP package. It features 125,000 system gates and supports up to 2,880 user I/O pins. The device operates at a maximum clock frequency of 200 MHz with a supply voltage range of 1.7V to 1.95V for core logic. It integrates non-volatile flash technology for instant-on configuration, eliminating the need for external configuration memory. Key internal resources include DSP slices, block RAM, and high-speed serial transceivers, designed for low-power embedded control and signal processing applications.

• Medical imaging equipment needing reliable, low-latency data handling
• Automotive infotainment systems requiring robust FPGA functionality

Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the selected variant meets all regulatory compliance standards for the intended deployment region.

Field Programmable Gate Array Selection Notes

Select this component when instant-on capability is critical and external configuration memory cannot be accommodated. Evaluate the 125K gate count against design complexity to ensure sufficient logic resources. Consider the 200 MHz performance limit for timing closure feasibility. Compare power consumption metrics against alternative FPGAs if battery life is a primary constraint. Verify I/O voltage levels match peripheral interfaces.

Field Programmable Gate Array Part Context

This model belongs to the ProASIC3 family, which bridges the gap between ASICs and standard FPGAs by offering non-volatility and lower static power. It serves as a drop-in replacement for older EPROM-based PLDs in many legacy designs. The TQG144 package provides a compact footprint suitable for space-constrained industrial and commercial electronics.

Field Programmable Gate Array Replacement Considerations

Direct replacements may include other ProASIC3 variants with different gate counts or packages, such as A3P060 or A3P250, depending on resource needs. Ensure pin-to-pin compatibility if upgrading within the same family. Verify that any substitute maintains the required flash configuration architecture.
