The 147456 total RAM bits provide on-chip block memory for FIFOs and small buffers without external SRAM. The 1.425V core supply and surface-mount 256FBGA footprint place it in the mid-density ProASIC3 tier — a fit for designs that need a single-chip logic fabric without a separate configuration PROM. The 'I' suffix in the order code flags the industrial temperature grade — the commercial-grade sibling (no suffix) is limited to 0°C to 85°C. ## Package and supply — 256FBGA, 1.425V core The 256-ball FBGA (Fine-pitch Ball Grid Array) requires a 4-layer or more PCB for fan-out of the 177 I/O. Core voltage is 1.425V nominal; I/O banks can be configured for 1.5V, 1.8V, 2.5V, or 3.3V depending on the bank supply pins.","metaTitle":"Microchip A3P1000-FGG256I ProASIC3 FPGA, 1M Gates, 177 I/O","metaDescription":"A3P1000-FGG256I ProASIC3 FPGA from Microchip. 1M system gates, 177 user I/O, 147456 bits RAM, 1.425V core.

They share the same 256FBGA package, 1M gate count, and 177 I/O — the 'I' suffix is the only difference. If your BOM specifies the commercial grade, the industrial part can be used as a drop-in upgrade with wider temperature margin, but verify the junction temperature limits against your thermal analysis."},{"question":"Does A3P1000-FGG256I support 1.5V operation?","answer":"The core supply is 1.425V nominal. The I/O banks can be configured for 1.5V operation by connecting the bank's VCCI supply to 1.5V — the ProASIC3 I/O structure supports 1.5V, 1.8V, 2.5V, and 3.3V standards. Confirm the bank voltage assignments in your Libero design tools."},{"question":"Is A3P1000-FGG256I RoHS compliant?","answer":"The 'G' in the order code (FGG256) indicates a RoHS-compliant, halogen-free, green package. The 256FBGA uses lead-free solder balls and the mold compound is free of antimony and brominated flame retardants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/A3P1000-FGG256I","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/A3P1000-FGG256I when reusing this data.
