A3P1000-1PQ208I

Field Programmable Gate Array Overview

The A3P1000-1PQ208I is a ProASIC3 Flash Field Programmable Gate Array manufactured by Microchip Technology. It features 24,576 Configurable Logic Blocks (CLBs) and approximately 1,000,000 system gates. The device operates with a nominal supply voltage of 1.5 V, ranging from 1.425 V to 1.575 V. It supports up to 154 user I/Os and includes 147,456 bits of embedded True Dual-Port SRAM. The component is housed in a 208-pin Plastic Quad Flat Package (PQFP) with a 0.50 mm pitch. It functions within an industrial temperature range of -40°C to +85°C.

Field Programmable Gate Array Feature Summary

• Non-volatile Flash-based architecture enabling instant-on functionality without external configuration memory.
• Supports mixed-voltage I/O standards including LVCMOS, LVTTL, LVDS, and PCI/PCI-X across multiple banks.
• Integrated Clock Control Center (CCC) blocks with Phase-Locked Loops for flexible clock management.

Field Programmable Gate Array Applications

• Industrial automation control systems requiring deterministic logic processing.
• Telecommunications infrastructure equipment utilizing high-speed serial interfaces.
• Test and measurement instrumentation involving signal conditioning and data acquisition.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '1' against current datasheets to confirm timing grade compatibility. Confirm RoHS status as legacy Actel/Microsemi products may have varying compliance declarations. Check for moisture sensitivity level requirements during storage and handling. Ensure design-in documentation matches the PQFP-208 package dimensions.

Field Programmable Gate Array Selection Notes

Select this model when instant-on capability is required to eliminate boot-up delays associated with SRAM-based FPGAs. Compare gate density and I/O count against the A3P250 or A3PE1500 if higher performance is needed. Verify that the 1.5V core voltage aligns with the target system power rails. Consider the PQFP-208 package availability relative to BGA alternatives for board space constraints.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash family, originally developed by Actel before its acquisition by Microsemi and subsequently Microchip. It bridges the gap between ASICs and SRAM-based FPGAs by offering reprogrammability with non-volatile storage. The A3P1000 represents a mid-range capacity option within the series, providing substantial logic resources in a standard QFP package.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package include the A3P1000-2PQ208I for different speed grades. For functional equivalents with similar gate counts but different packages, consider the A3P1000-1FGG256T. Cross-family migration to ProASIC3E or IGLOO2 requires schematic and firmware adaptation.
