EP3C55F484C8N 概要
A Cyclone III FPGA is a SRAM-configurable logic device positioned in the low-cost FPGA tier, below the Stratix and Arria families. Cyclone III belongs to the broader FPGA hierarchy: programmable logic -> FPGA -> SRAM-based FPGA -> low-power FPGA. The family targets cost-sensitive applications such as industrial control, video processing, and communications infrastructure where Stratix-class performance is unnecessary but a true programmable fabric is still required.
Key features include 55856 logic elements, 2396160 embedded memory bits distributed across M9K blocks, 4 PLLs for clock management, and 343 multiplier blocks (18x18) enabling DSP functions without external multipliers. Per the Alldatasheet entry the package is described as 23 x 23 mm FBGA-484 with 2.60 mm height and 1 mm pitch, lead-free, and the device is RoHS compliant. The Cyclone III family uses a 65 nm TSMC process that delivers significantly lower static and dynamic power than the prior Cyclone II generation while preserving pin compatibility in many footprints.
Typical applications span industrial motor and machine control, video surveillance and image processing, software-defined radio front-ends, low-cost ASIC prototyping, automotive infotainment ECUs, and consumer display controllers. The 327 I/O and rich DSP blocks also make the part a frequent choice for educational FPGA development kits and university digital logic labs.
When designing with the EP3C55F484C8N, place all VCCINT and VCCA decoupling capacitors within a few millimetres of the balls, use at least 4 signal layers to escape the dense 1.0 mm pitch BGA, and respect the Quartus II / Quartus Prime JTAG configuration sequence including nCONFIG, nSTATUS, and CONF_DONE handshakes. Power sequencing must bring VCCINT up before VCCA per the Cyclone III Device Handbook.

主な用途
EP3C55F484C8N の用途: 6 件s: Industrial Motor Control, Video Surveillance and Image Processing, Software-Defined Radio Front-End, ASIC Prototyping, Automotive Infotainment ECU, Educational FPGA Development Boards.
Industrial Motor Control
The EP3C55F484C8N fits industrial motor control because it offers 260 embedded 18x18 multipliers, 4 PLLs, and 327 user I/O - enough parallel math blocks to vector-FOC or space-vector-PWM a 3-phase inverter in a single device. The 472 MHz internal clock closes timing on the SVPWM carrier period at 20 kHz with margin. Its 484-FBGA package exposes sufficient pins for parallel ADC sampling (12-16 channels) plus incremental encoder inputs, while the 65 nm low-power Cyclone III process keeps inverter-stage logic dissipation manageable in a sealed cabinet.
おすすめ
Video Surveillance and Image Processing
For video surveillance pipelines the EP3C55F484C8N's 2,396,160 embedded memory bits (260 M9K blocks) buffer full-HD frames line-by-line at 148.5 MHz pixel clock, and the 260 18x18 multipliers implement 2D convolution, Sobel edge detection, and motion-vector estimation in real time at 30 fps. With 327 I/O the part can accept parallel BT.1120 / digital video from a CMOS sensor plus a DDR2 SDRAM controller for frame storage. The 1.2 V core and Cyclone III low-power architecture keep thermal rise inside a sealed PoE camera housing without a heatsink.
おすすめ
Software-Defined Radio Front-End
The EP3C55F484C8N suits SDR front-end DSP because its 260 18x18 multipliers and 4 PLLs deliver enough GFLOPS to implement a 4-channel DDC (digital down-converter) chain plus channelization at baseband sample rates up to 122.88 MHz. The 472 MHz fabric clock and dedicated PLL re-save clock network lock to a low-jitter external VCXO for ADC sampling. With 327 I/O the FPGA interfaces to parallel LVDS ADCs / DACs, while the 484-FBGA 1.0 mm pitch enables a small 4-layer PCB suitable for an embedded SDR module.
おすすめ
ASIC Prototyping
ASIC prototyping with the EP3C55F484C8N leverages its 55,856 logic elements, 260 M9K RAM blocks, and 260 multipliers to emulate medium-complexity ASICs up to ~1.5 M gates. The 327 user I/O can be partitioned across multiple FPGA logic analyzers and BIST controllers, and the SRAM-based fabric supports unlimited design iterations via JTAG. Designers partition the ASIC across 1-3 FPGAs using Quartus II and verify at speed, accelerating time-to-silicon compared with simulation alone.
おすすめ
Automotive Infotainment ECU
The EP3C55F484C8N powers automotive infotainment ECUs by bridging LVDS / OpenLDI display panels, MOST or CAN networks, and audio CODECs over its 327 user I/O. The 260 multipliers handle audio DSP (EQ, crossover, time alignment), while 2.4 Mbit embedded memory supports display frame-buffer double-buffering. The commercial-grade 0 to +85 C temperature range fits cabin-mounted head units; for harsher under-hood designs use the EP3C55F484I7N industrial variant instead. Quartus Prime flow integrates CAN IP cores and MOST network stacks.
おすすめ
Educational FPGA Development Boards
The EP3C55F484C8N is a popular FPGA on university and hobbyist development boards because it provides 55,856 logic elements - enough to run RISC-V soft cores, custom 32-bit CPUs, and complete VHDL/Verilog coursework projects - at a price point affordable for educational kits. The 327 I/O drives onboard LEDs, switches, character LCDs, VGA / HDMI interfaces, and GPIO headers. The 484-FBGA package is manageable on a 4-layer educational PCB, and Quartus II Web Edition supports the entire Cyclone III family free of charge.

主な差別化要因
- Highest Fmax bin on the 484-FBGA Cyclone III family (vs EP3C55F484C7N)
- RoHS-compliant Pb-free ball finish for global sale (vs EP3C55F484C8 (non-N suffix))
- Mid-density 55K LE sweet spot for balanced designs (vs EP3C40F484C8N)
設計ノート
Estimated: at 1.2 V VCCINT, the EP3C55F484C8N core current can reach approximately 0.8 to 1.2 A depending on toggle rate. Place 100 nF + 10 uF decoupling capacitors within 5 mm of every VCCINT ball, and at least one 100 uF bulk tantalum near the regulator. Bring VCCINT up before VCCA per the Cyclone III Device Handbook to avoid latch-up; sequence VCCA (~2.5 V) within 100 ms of VCCINT. The 327 I/O on VCCIO banks can draw an additional 1 to 2 A when heavily loaded, so size the VCCIO regulator for the specific bank count actually used.
The 484-FBGA uses a 1.0 mm ball pitch which is escapeable on a 4-layer PCB with via-in-pad or microvia process. Use 0.5 mm via capture pad with 0.2 mm drill and a 4 mil trace width to break out the inner rows. Maintain at least 2 mm of continuous reference plane under the package for power integrity, and avoid routing signals across split power planes between VCCINT and VCCA. Per JEDEC J-STD-020 the FBGA is MSL3 - bake at 125 C for 24 hours before assembly if the sealed bag has been open longer than the floor-life limit.
Do not confuse speed grade 8 with package code 484; the '8' here is the Fmax bin, not a ball count. Be aware that EP3C55F484C8N is a commercial-temperature device - for industrial applications you must select the I7N variant. The non-N suffix parts (C8, C7, C6) are older Pb-ball revisions and may not be RoHS compliant for sale into the EU. Finally, Quartus Prime support for Cyclone III ended at version 20.1; older Quartus II 13.0sp1 is still required for many legacy IP cores and must be retained alongside the newer toolchain.
コンプライアンス情報
