EP1C20F400 Présentation
A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect that can be reconfigured by the designer after manufacturing. In the system hierarchy, an FPGA sits above microcontrollers and below application-specific integrated circuits (ASICs), offering hardware-level parallelism, deterministic timing, and fast time-to-market. The Cyclone family specifically targets cost-sensitive, logic- and DSP-intensive designs in industrial, consumer, and communications markets.
Key features of the EP1C20F400 include 20,060 logic elements (LEs) at the high end of the original Cyclone family, 294,912 bits of RAM distributed across 301 M4K blocks (each 4 Kbit + parity), 8 dedicated PLLs, and a multiplier block density of 20 embedded 18×18 multipliers. The 400-ball FineLine BGA exposes up to 301 user I/Os and supports multiple I/O standards including LVDS, LVTTL, LVCMOS, PCI, and SSTL. Single-ended data rates up to 640 Mbps and LVDS rates up to 840 Mbps make the part well suited for parallel digital interfaces and low-speed serial links.
Architecturally, the device uses a 1.5 V core supply with separate VCCIO banks for I/O flexibility. Configuration is supported via passive serial (PS), active serial (AS), and JTAG modes, with the ability to load bitstreams from EPCS serial configuration devices. The 0.13 µm process delivers typical static core current of approximately 150 mA and dynamic current that scales with logic utilization and toggle rate.
Typical applications include industrial control and motor drive signal conditioning, video processing and image-capture front-ends, low-cost software-defined radio (SDR) baseband blocks, telecom line-card glue logic, and prototyping platforms that migrate to Cyclone II or Cyclone III in production. The generous memory and DSP blocks also make EP1C20F400 a popular FPGA for university labs and embedded teaching kits.
When designing with this part, derate the 301 I/Os against the chosen I/O standard's VCCIO bank constraints, keep the JTAG chain free of stubs, and provide a clean 1.5 V core rail with at least one decoupling capacitor per VCC pin. Designers transitioning to newer Cyclone generations should note that the EP1C20 is not bitstream-compatible with Cyclone II/III/IV — a redesign of the configuration and timing constraints is required.
This page synthesizes distributor availability, drop-in same-package alternatives from the Cyclone family, and practical design notes that go beyond the manufacturer datasheet to help engineers evaluate and source the EP1C20F400 with confidence.

The EP1C20F400's 294,912 bits of embedded RAM buffer full D1 video frames line-by-line, while the 20 dedicated 18×18 multipliers accelerate 2D filter, scaling, and chroma-conversion kernels in real time. Its support for LVDS up to 840 Mbps enables direct interfacing to high-speed image sensors and flat-panel display controllers, and the 301 user I/Os drive wide parallel video buses without external bus switches. Quartus II's DSP Builder and the Cyclone I LVDS IP cores shorten time-to-market for streaming-video designs in security, machine-vision, and medical imaging.
Recommandé
Telecom Line-Card Glue Logic and Protocol Bridging
The EP1C20F400 acts as a flexible protocol bridge on telecom line cards by aggregating low-speed serial links (T1/E1, HDLC, I²C, SPI) into a single backplane interface, using the 8 PLLs to synthesize all the required reference clocks. Its 20,060 logic elements implement deep state machines for protocol translation, while the 301 user I/Os fan out to many downstream PHYs without external bus expanders. The Cyclone I LVDS capability (up to 840 Mbps) supports inter-board backplane links at typical telecom backplane rates, and the JTAG interface eases board-level boundary-scan test in production.

Notes de conception
The EP1C20F400 uses a 1.5 V core (VCCINT) plus per-bank VCCIO rails that may be set to 1.5 V, 1.8 V, 2.5 V, or 3.3 V depending on the I/O standard. Place one 0.1 µF decoupling capacitor directly adjacent to every VCCINT and VCCIO pin, plus bulk 100 µF tantalum or ceramic capacitors on each supply rail. Estimated: at 100% logic utilization with 50% toggle rate, expect 500–800 mA on VCCINT (1.5 V) — verify with the Quartus II PowerPlay early-power estimator before locking the BOM. The PLL analog supply (VCCA_PLL) must be filtered with a ferrite bead and decoupled with 0.1 µF and 10 µF capacitors per PLL.
The 400-ball FineLine BGA uses 1.00 mm ball pitch, so PCB fabrication must support microvia or 4–6 mil laser-drilled vias. Fan-out every VCCINT/VCCIO/GND ball to its own via, never share vias between balls. Use a 4–6 layer stack-up with dedicated GND and VCCINT planes directly under the BGA, and route LVDS pairs with 100 Ω differential impedance and length matching within ±150 mil. The JTAG TDI/TDO/TMS/TCK chain should be guarded by ground traces and not branch into stub loads; place a 10 kΩ pull-up on TCK and TMS per the Cyclone family datasheet.
Do not assume the EP1C20F400 bitstream is forward-compatible with Cyclone II/III/IV — the configuration bit format, JTAG instructions, and timing models differ. If migrating, plan for a full Quartus recompile and timing-closure re-run. Also, never leave CONFIG_DONE floating; pull it high with a 4.7 kΩ resistor so the FPGA clearly indicates configuration status. Finally, respect the MSEL[2:0] pin strapping: incorrect MSEL values put the device in an unsupported configuration mode and the EPCS device will not boot.
Place the EPCS serial configuration device within 50 mm of the FPGA DCLK/DATA/nCS pins to keep signal integrity margins healthy; route DCLK as a 50 Ω controlled-impedance trace and DATA with a 4.7 kΩ pull-up. Use the Altera USB-Blaster or a compatible JTAG programmer and ensure JTAG connector pinout matches the 10-pin Altera standard. For high-utilization designs, enable the Quartus II Design Assistant and run the Chip Planner early to catch routing congestion in the 400-ball BGA fan-out before committing to layout.
