EP1S20F780I6 - Stratix FPGA 18,460 LEs 586 I/O 780-BGA | Intel
The Intel EP1S20F780I6 is a high-density Stratix family Field Programmable Gate Array (FPGA) providing 18,460 logic elements, 1,669,248 bits of embedded RAM, 586 user I/O pins, and 60 embedded multipliers in a 780-ball FineLine BGA package, industrial grade speed grade -6.
An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device that lets engineers implement custom digital logic, memory blocks, DSP pipelines, and high-speed serial interfaces after fabrication. The Stratix family sits within Intel's (formerly Altera's) high-performance FPGA portfolio, between the lower-density Cyclone series and the higher-end Stratix GX / Stratix II / Stratix III tiers. Stratix devices use a 1.5 V core, embedded TriMatrix memory, dedicated DSP blocks, and high-speed I/O standards including LVDS, HSTL, SSTL, and LVTTL, making them well suited for parallel DSP, video/ imaging pipelines, communications backplanes, and prototype ASIC verification.
Key features of the EP1S20F780I6 include 18,460 logic elements distributed across 1,846 LABs (Logic Array Blocks), 14 embedded memory blocks (M-RAM, M4K, M512) totaling 1,669,248 RAM bits, 60 embedded 18x18 multipliers, four phase-locked loops (PLLs), and support for up to 586 user I/O pins via 29 I/O banks. The 780-ball FCBGA package exposes LVDS, HSTL, and SSTL I/O standards. Configuration is supported through passive serial, fast passive parallel, and JTAG modes, with optional on-chip encryption via the Stratix security feature.
Architecturally, the EP1S20F780I6 uses a 0.13 μm 1.5 V SRAM-based logic fabric with embedded RAM (M-RAM 4 Kb blocks plus M4K 4 Kb and M512 512-bit blocks), which avoids the long compile and re-spin costs of ASIC development. Compared with Stratix GX, the EP1S20 omits dedicated 3.125 Gbps transceivers; designs needing multi-gigabit serial should step up to Stratix GX. Compared with Cyclone II, the Stratix line adds TriMatrix memory, more multipliers, more PLLs, and richer I/O standard support, which translates to higher throughput for DSP, video, and communications front ends.
Typical applications include ASIC prototyping, parallel DSP (FFT, FIR, modulation/demodulation), video and image processing frames, industrial control and factory automation, telecom baseband and backplane bridging, and military/aerospace signal processing. The wide I/O count (586 pins) and abundant multipliers (60) make it attractive for multi-channel baseband cards and high-lane-count imaging arrays.
When designing with the EP1S20F780I6, allocate at least two PCB layers for power and ground planes, use a minimum of six dedicated 0.1 μF + bulk decoupling capacitors per VCC pin group, and follow Altera's Stratix Hardware Design Guidelines for high-speed transceiver-less I/O. JTAG and EPC configuration devices should be referenced to the same 1.5 V core supply plane to avoid inrush glitches.
