EP3SL200H780I4N - Stratix III L FPGA 200K LE 780-HBGA | Intel
The Intel (formerly Altera) EP3SL200H780I4N is a high-density, low-power Stratix III L family Field Programmable Gate Array (FPGA) integrating 200,000 logic elements, 10,901,504 bits of embedded memory, and 488 user I/Os in a 780-ball FineLine BGA (FCBGA) package. Built on a 65 nm CMOS process and operating from a 1.1 V core supply, this device is targeted at high-performance digital signal processing, ASIC prototyping, and high-bandwidth data-path applications where the combination of logic density, memory bandwidth, and rich transceiver/PLL resources is critical.
What is a Stratix III FPGA? The Stratix III family is a high-performance FPGA platform from Altera/Intel that delivers a logic, memory, DSP, and I/O fabric in a single reprogrammable device. FPGAs in this hierarchy are programmable semiconductors that sit alongside ASICs, microcontrollers, and processors; designers implement custom logic by configuring on-chip look-up tables (LUTs), embedded memory blocks (M9K/M144K), DSP blocks, and PLLs. The Stratix III family specifically introduced a 'logic-rich' variant ('L') that doubles on-chip memory relative to earlier Stratix generations, enabling large FIFO and packet-buffer implementations without external SRAM.
The EP3SL200H780I4N variant carries the 'I4' speed grade and 'N' lead-free suffix, indicating an industrial temperature range (typically -40C to +100C) suitable for telecom, aerospace, and ruggedized industrial systems. The 'L' suffix denotes the logic-rich variant, and the part number encodes 488 user I/Os, a 780-pin FineLine BGA with flip-chip die attach, and 8,000 logic array blocks (LABs). Transceiver count, PLL count, and global clock network details are device-specific and should be confirmed against the manufacturer datasheet.
Performance highlights of this device class include up to 450 MHz core fabric performance, dedicated 18x18 multipliers and hardware DSP blocks that can be cascaded into higher-precision filters, and Programmable Power Technology that reduces dynamic power on quiescent logic. The 780-ball FCBGA package uses flip-chip land-grid construction with an integrated heat spreader lid, providing a thermal envelope compatible with forced-air and conduction-cooled system designs when correctly mounted.
Typical applications for the EP3SL200H780I4N include high-throughput packet processing in network switches and routers, ASIC and ASSP prototyping for CPU subsystems and image-pipeline designs, software-defined radio baseband processing, military/aerospace signal intelligence, medical imaging accelerators, and test-and-measurement instrumentation requiring deep logic and memory parallelism. The Stratix III L family was broadly deployed in early-2010s high-end wireline and wireless infrastructure, including 40G/100G Ethernet line cards and LTE baseband pre-prototyping.
When designing with the EP3SL200H780I4N, ensure that PCB layout follows Altera's High-Speed Board Design guidelines: matched-length differential pairs for DDR2/DDR3 memory interfaces, controlled-impedance (typically 50 ohm single-ended / 100 ohm differential) routing for clock and global signals, and a minimum of 6 PCB layers with continuous reference planes. Power-rail decoupling requires bulk capacitors near each VCORE/VCCIO supply pin plus high-frequency MLCCs placed within 100 mil of the BGA balls. Quartus II (or its successor) is required for synthesis, place-and-route, and bitstream generation.
