The 1.425 V core supply is a single rail, which simplifies the power tree compared to older FPGAs that required separate 1.2 V, 1.5 V, and 1.8 V supplies. ## On-chip memory — 147456 bits of block RAM The 147456 bits of embedded RAM are distributed across the fabric as 4,608-bit blocks. This is enough for small FIFOs, coefficient tables, or line buffers in video applications up to about 640×480 resolution. Designs needing larger data buffers — Ethernet frame stores, full-frame video — will require external SRAM or SDRAM connected through the user I/O.","metaTitle":"Microchip A3P1000-FG484I ProASIC3 FPGA, 1M Gates, 300 I/O","metaDescription":"Microchip ProASIC3 A3P1000-FG484I FPGA: 1 million gates, 300 I/O, 147456 bits RAM, 1.425 V core, -40°C to 100°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["FPGA / CPLD & Programmable Logic"],"specifications":{"series":"ProASIC3","has_mpn":"A3P1000","package_type":"Tray","Number Of I/O":"300","mounting_type":"Surface Mount","Total Ram Bits":"147456","product_status":"Active","Number Of Gates":"1000000","lifecycle_stage":"eol_hot","supply_voltage_v":"1.425","Operating Temperature High":"-40°C to 100°C (TJ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$115.90","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.microsemi.com/document-portal/doc_download/130704-ds0097-proasic3-family-flash-fpgas-datasheet","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the A3P1000-FG484I and how do I get a price?","answer":"The A3P1000-FG484I is available to order through independent distribution.
