EP1AGX50DF1152I4N - Arria GX FPGA, 50K LE, 1152-BGA | Altera
The Altera EP1AGX50DF1152I4N is a member of the Arria GX family of field-programmable gate arrays (FPGAs), combining 3.125 Gbps serial transceivers with a 50K-equivalent logic element fabric in a 1152-ball FineLine BGA package. The device integrates 514 user I/O pins, up to 2,475,072 bits of embedded memory, and 50,160 logic elements (LEs), making it suitable for high-throughput parallel processing, high-speed serial interfacing, and protocol bridging applications in communications, industrial imaging, and broadcast video systems.
An FPGA (Field-Programmable Gate Array) is a semiconductor device whose digital logic fabric, interconnect, and I/O cells are user-configurable after manufacture. FPGAs occupy the middle ground between fixed-function ASICs and software-driven processors: they provide hardware parallelism and deterministic latency for data-path intensive workloads while still allowing in-system reprogramming for bug fixes, feature upgrades, and protocol adaptation. Modern high-end FPGAs like the Arria GX additionally embed hard IP blocks - transceivers, memory controllers, PLLs, and DSP multipliers - that deliver ASIC-class performance while preserving FPGA programmability.
Key features of the EP1AGX50DF1152I4N include eight 3.125 Gbps multi-gigabit transceivers, dedicated DSP blocks for high-throughput arithmetic, distributed and embedded memory for buffer and lookup-table use, and a programmable phase-locked loop (PLL) network for clock synthesis. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL, enabling direct connection to DDR/DDR2 memories and a wide range of parallel peripherals. The I4N speed grade and industrial temperature range (-40C to +100C ambient) ensure reliable operation in harsh environments.
Architecturally, the Arria GX device combines a logic fabric built from adaptive logic modules (ALMs), TriMatrix embedded memory blocks (M512, M4K, M-RAM), and dedicated DSP blocks. The integrated transceivers operate over multiple channels at data rates from 600 Mbps to 3.125 Gbps, supporting protocols such as PCI Express, Gigabit Ethernet, Serial RapidIO, and XAUI. The 1152-ball BGA package provides ample routing density for high-speed serial and parallel interfaces on multi-layer PCBs.
Typical applications include high-speed serial protocol bridges, telecom line cards, broadcast video processing, industrial imaging pipelines, and ASIC prototyping. The combination of 3.125 Gbps transceivers, 50K LEs, and a generous I/O budget makes this device well-suited for designs where both parallel processing bandwidth and multiple high-speed serial links are required.
When designing with the EP1AGX50DF1152I4N, allocate sufficient PCB layers to route the 1152-ball BGA fan-out, follow Altera's power distribution network guidelines with multiple decoupling capacitors at each supply pin, and use the Altera Quartus II design suite for synthesis, place-and-route, and timing closure. PCB layout should respect 90-ohm differential impedance for the transceiver channels and maintain matched-length traces across all high-speed serial lanes.
