EP3SL50F484I4LG - Stratix III L FPGA, 47.5K LE, 484-FCBGA | Altera (Intel)
MPN: EP3SL50F484I4LG ✗ Cuối đờiEP3SL50F484I4LG Tóm tắt
A Field Programmable Gate Array (FPGA) is a programmable logic device that lets designers implement arbitrary digital logic, memory blocks, and DSP functions through a hardware description language. Within the broader semiconductor taxonomy, FPGAs sit between ASICs and processors: programmable like a processor, but parallel and deterministic like an ASIC. The Stratix III family uses a power-optimized 40nm process that reduces dynamic power roughly 30% versus prior Stratix generations while preserving the high logic capacity that Stratix devices are known for.
Key features of the EP3SL50F484I4LG include 47,500 logic elements (LEs), 2,184,192 bits (273 KB) of embedded RAM, embedded multipliers and DSP blocks for high-throughput arithmetic, dedicated PLL and clock-tree resources, and 296 general-purpose user I/Os. The device supports up to 12 transceiver channels in higher Stratix III L SKUs, with the L suffix denoting the low-power variant of the family.
The Stratix III L architecture uses Programmable Power Technology that automatically switches logic on or off based on the operating frequency, allowing unused logic to draw near-zero leakage. This makes the EP3SL50F484I4LG suitable for high-utilization designs that would otherwise over-budget power in older FPGA families.
Typical applications include high-throughput DSP pipelines (radar, beamforming, video processing), high-speed serial protocol bridging (PCIe Gen2, Serial RapidIO, GBE), ASIC prototyping, and telecom baseband pre-processing. The 296 user I/Os are typically distributed across multiple I/O banks to support mixed voltage standards (LVDS, LVTTL, HSTL, SSTL).
When designing with this device, pay close attention to decoupling, signal integrity on the FCBGA breakout, and transceiver reference-clock routing. Use Altera's Quartus II design suite for synthesis, place-and-route, and timing closure.

Ghi chú thiết kế
The 484-ball FCBGA package requires a PCB stack-up with microvias or via-in-pad for breakout. Use a 1-6-1 or 1-8-1 stack-up with sequential lamination to route signals out of the inner balls without via stubs. Maintain 100-ohm differential impedance on transceiver lanes and 50-ohm single-ended on GPIO. Decouple each power rail (VCCINT, VCCAUX, VCCIO) with 0.1uF MLCCs within 100 mils of each ball.
Stratix III L uses Programmable Power Technology to gate unused logic, but at high utilization (above 70% LE usage) the device still draws 5-10W typical. Provide a thermal pad or copper pour on the top PCB layer connected to GND; for enclosed chassis, plan a heatsink with 1-2 C/W thermal resistance to keep junction below 100C. The -40C to +100C industrial grade requires this margin at worst-case ambient.
Place configuration mode jumpers (MSEL pins) near the FPGA and route JTAG (TCK, TMS, TDI, TDO) with impedance-controlled traces under 6 inches to avoid programming failures. Differential clock inputs require 100-ohm termination at the FPGA ball. Avoid routing noisy I/O signals near PLL power pins (VCCA_PLL) to minimize jitter.
Common pitfalls include: (1) selecting a slower speed grade (I3) for a design that closes timing at I4 only - verify timing closure with margin; (2) forgetting pull-ups on configuration pins causing boot failures; (3) under-estimating transceiver reference-clock jitter - use a low-jitter clock source within the Stratix III datasheet spec; (4) not enabling the on-chip temperature sensor when designing for industrial temperature compliance.
