A3P125-2VQG100I

Field Programmable Gate Array Overview

The A3P125-2VQG100I is a ProASIC3 Flash Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It features 125,000 system gates and 71 user I/Os within a 100-VQFP package. The device operates on a core supply voltage ranging from 1.425 V to 1.575 V and supports an industrial temperature range of -40°C to +100°C. It includes 36,864 bits of total embedded RAM and achieves maximum clock frequencies up to 350 MHz.

Field Programmable Gate Array Feature Summary

• Non-volatile flash-based architecture providing instant-on functionality without external configuration memory.
• Supports mixed-voltage I/O standards including LVCMOS and LVTTL with bank-selectable voltages.
• Includes configurable logic blocks and embedded SRAM for complex digital logic implementation.

Field Programmable Gate Array Applications

• Industrial control systems requiring robust non-volatile programmability.
• Automotive electronics operating in extended temperature environments.
• Communication interface adapters utilizing mixed-voltage signaling.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '2' indicates the industrial temperature grade (-40°C to +100°C) and 'I' confirms the lead-free/RoHS compliant status. Confirm the package marking matches the 100-VQFP form factor. Ensure design files are compatible with the ProASIC3 family tools. Check for any recent PCN updates regarding assembly or material changes.

Field Programmable Gate Array Selection Notes

Select this model when non-vatile storage and instant-on capability are required, distinguishing it from SRAM-based FPGAs. Compare gate counts and I/O availability against similar ProASIC3 variants like the A3P125-1 series if commercial temperature grades suffice. Verify that the 100-pin VQFP footprint fits the PCB layout constraints and thermal requirements.

Field Programmable Gate Array Part Context

This component belongs to the Microchip ProASIC3 Flash FPGA family, which bridges the gap between ASICs and traditional SRAM-based FPGAs. The family offers high density with low power consumption and inherent security due to its flash technology. The A3P125 variant provides a mid-range capacity suitable for moderate complexity designs.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package include other A3P125 variants such as A3P125-1VQG100I, provided the temperature grade difference is acceptable. Cross-family migration to ProASIC3E or IGLOO may require schematic and layout redesigns due to architectural differences.
