EP1AGX20CF484C6NGA
EP1AGX20CF484C6NGA - 20K LE Arria GX FPGA, 484-FBGA | Intel
The Intel EP1AGX20CF484C6NGA is a member of the Arria GX FPGA family, providing 21,580 logic elements, 1,229,184 bits of embedded RAM, and a high-speed serial transceiver fabric in a 484-pin FineLine BGA package (23x23 mm). The device supports 230 user I/O pins and operates from a 1.15V to 1.25V core supply, with -6 speed grade transceivers rated for multi-gigabit serial links. This makes the EP1AGX20CF484C6NGA a balanced mid-density programmable-logic choice for designs that need both substantial logic capacity and integrated 3.125 Gbps-class SERDES.
An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory blocks, DSP blocks, and programmable routing. FPGAs occupy the high-end of the programmable-logic hierarchy, sitting above CPLDs (smaller, non-volatile, lower-density) and below ASICs in performance-per-watt. The Arria GX family specifically targets cost-sensitive applications that still require transceivers, bridging the gap between Cyclone (no SERDES) and Stratix (high-end SERDES + DSP) within Intel's programmable-logic portfolio. The 'AGX' prefix denotes the Arria GX sub-family; '20' is the logic-density code.
Key features of the EP1AGX20CF484C6NGA include integrated transceivers supporting CPRI, PCI Express (Gen1), Gigabit Ethernet, Serial RapidIO, and SDI protocols; embedded multipliers and DSP blocks; phase-locked loops for clock management; and configuration via passive serial, fast passive parallel, JTAG, or Altera EPCS/EPCQ flash. The -6 speed grade is a mid-tier speed bin, balancing Fmax and power. The 484-FBGA package exposes 230 user I/O pins, leaving significant headroom for parallel interfaces such as DDR/DDR2 memory controllers and LVDS channels.
Architecturally, the Arria GX fabric combines 4-input LUT-based logic elements, M512/M4K/M-RAM memory blocks, MLABs, and dedicated 18x18 multipliers feeding hardened DSP blocks. The transceiver blocks (up to 8 in this device) integrate serializer/deserializer, clock-data recovery, and physical coding sublayer logic, offloading serial I/O entirely from the programmable fabric. Configuration is stored in SRAM cells, requiring a boot flash or JTAG controller for stand-alone operation.
Typical applications for the EP1AGX20CF484C6NGA include wireless baseband preprocessing, broadcast video routers and switchers, industrial imaging and machine vision, military radar and signal-intelligence front ends, and protocol-bridging cards for telecom backplanes. The device's combination of mid-density logic, embedded transceivers, and 230 I/O makes it well-suited to designs that must aggregate multiple legacy interfaces (parallel data, LVDS, SERDES) onto a single board.
When designing with the EP1AGX20CF484C6NGA, engineers should follow Intel's power-decoupling guidance for Arria GX, place the EPCS configuration flash within 4 inches of the FPGA, and observe the JTAG chain topology if multiple Intel devices share the bus. Transceiver channels require matched-length differential routing and AC-coupling capacitors per Intel's pin-out guidelines.
