Altera Cyclone FPGA & MAX CPLD Boards
Altera Cyclone FPGA boards, MAX CPLD boards and programming accessories
This series combines Cyclone II and Cyclone IV FPGA development hardware, MAX II and MAX7000S CPLD boards, USB-Blaster-style programming adapters, a ten-pin breakout cable, and even a bare-chip variant. It is not a set of interchangeable Altera FPGA chips. The product selection determines whether you receive a populated board, a loose EP2C5 chip, a downloader, a harness or a multi-piece educational kit. Altera design names now appear in Intel programmable-logic ecosystems; neither the collection name nor supplier branding verifies device provenance or official manufacturer affiliation. Identify the physical item, exact silicon part, connector and toolchain before ordering.
Cyclone IV EP4CE6, EP4CE10 and EP4CE22 core boards
Several compact boards are offered around EP4CE6E22C8N; other options select EP4CE10E22C8N, while one multi-model headline also mentions EP4CE22E22C8N. In that listing, the selectable Model Number values shown are EP4CE6E22 and EP4CE10E22, both marked “Finished product”; the headline's EP4CE22 reference does not create a selectable EP4CE22 board. Supplier description for that 52 × 52 mm core board specifies 5 V board input, mini-USB or header power, a 50 MHz oscillator, 16 Mbit configuration flash, JTAG and 2.54 mm pin headers. These are attributes of that described assembly, not a promise for every board here. The seller specifically warns that a set of pins on its proposed EP4CE22 option are special-function pins, not general-purpose I/O; verify the actual fitted chip and pin map rather than assuming all nominal package pins are user I/O.
Another EP4CE6 core-board offer lists a Type-C 5 V input, 50 MHz oscillator and 16 Mbit SPI flash, but its Color selector has three fundamentally different outcomes: “EP4CE6E22C8N Core,” “EP4CE10E22C8N Core” and “USB Blaster.” Selecting USB Blaster does not purchase the core board. Other EP4CE6 listings use Model Number as quantity: 1pc, 5pcs or 10pcs, and another offers 1PC, 2PCS or 3PCS. These are pack counts rather than different FPGA families. “2.5V” in a headline or generic supplier supply-voltage field may refer to an internal rail or an I/O domain; it does not establish that the assembled board must be fed from a 2.5 V external supply. Read the selected board's schematic and connector legend before applying power. “Compatible for Arduino” is not proof of Arduino shield pinout, voltage compatibility or plug-and-play library support.
Educational Cyclone IV kits: what the bundle actually includes
The EP4CE6/EP4CE10 white-box kit variants select one of two populated devices. Its supplier lists a development board, USB programmer, power cable and protective box, with onboard EPCS16N configuration memory, SDRAM and classroom peripherals described for the board. That list should not be generalized to compact core-only listings. Another EP4CE10 teaching-board listing supplies six distinct Color bundles: bundle1 is described as board, USB programmer and power cable; bundle2 adds connecting board, VGA module, OV7670 camera, TFT LCD, Ethernet and USB modules; bundle3 adds connecting board, VGA module and camera; bundle4 adds connecting board, TFT and camera; bundle5 adds connecting board and Ethernet module; bundle6 adds connecting board and USB module. The source text describes a 136 × 106 mm board with 64 Mbit SDRAM, EPCS16N, LEDs, switches, PS/2, serial, VGA and LCD interfaces. An interface on the board is not proof that its external module is included in the smallest bundle. Its source also gives conflicting figures for the VGA module's color depth and oversimplifies JTAG configuration persistence: a volatile SRAM FPGA configuration loaded directly by JTAG is normally lost when power is removed, whereas programming compatible nonvolatile configuration memory is a separate operation. Check the programming target, file format and selected package with the item's documentation.
Cyclone II EP2C5 minimum systems and a bare IC option
EP2C5T144 Cyclone II boards are described with 5 V board input, EPCS4 4 Mbit configuration memory, a 50 MHz oscillator, indicator LEDs and reset switch. One listing offers “EP2C5T144C8 Module” versus “EP2C5T144C8N Chip”: the latter is a chip selection, not a working minimum-system board with oscillator and voltage regulators. A separate EP2C5T144 learning-board offer is a single default board option. Check the full part suffix, FPGA package, programmed configuration device, pin-header pitch, correct board supply and GPIO voltage before building a carrier. Nios II is a configurable processor soft core/design flow, not a separate hard CPU guaranteed to run out of the box on these boards.
MAX II and MAX7000S: CPLD is not a Cyclone FPGA
EPM570TC144C5 MAX II is described as a board with 570 logic elements, 116 I/O signals and 4,096 user-flash bits; its shipping list says one development board, and explicitly says a USB Blaster is needed to program it. Do not assume the downloader is in the box. EPM7128SLC84 MAX7000S is a different CPLD board with described 5 V board input, JTAG, LEDs, switches, four-digit display, LCD1602 socket, buzzer, PS/2 and serial connection; its supplier mentions power and serial cables. Its I/O electrical behavior and legacy device programming support cannot be inferred from EPM570 or Cyclone IV. A CPLD's architecture, device resources, configuration behavior and tool-version requirements are distinct from an FPGA's; check timing, pin assignments and Quartus support for the exact device before migrating a design.
USB Blaster programmers and the cable-only item
A mini USB Blaster, a separate USB-Blaster-style adapter and an FT245+CPLD downloader appear as products in this collection. The FT245 listing has Color options “downloader” and “Development board,” so one price cannot represent both hardware assemblies. A 2 × 5 to ten-way 2.54 mm IDC/Dupont cable listing describes one approximately 30 cm passive harness, not a USB programmer, logic analyzer or FPGA. Pin order, pin 1 orientation, keying, JTAG voltage reference, target supply and software driver determine whether a programmer can communicate with a particular board. Supplier claims of universal Altera device support, Rev.C firmware, faultless SignalTap operation and extreme performance are not verified guarantees. Legacy MAX/Cyclone parts and current Intel FPGA families may require different Quartus releases or programmer support; confirm the exact device, OS, driver and firmware before buying. A Saleae-style logic analyzer captures external signals; the passive adapter cable cannot itself program or analyze a device.
Engineering selection checklist
- Identify silicon: EP2C5, EP4CE6, EP4CE10, EP4CE22, EPM570 and EPM7128 differ in architecture, package, logic resources, RAM, embedded multipliers and usable I/O. The suffix matters for speed, temperature and pin map.
- Read the selected option literally: Color can mean core board, USB Blaster, chip, development board or six different teaching kits. Model Number may instead mean 1/2/3/5/10 pieces. Selectors do not imply all models ship together.
- Check power domains: board input, FPGA core, PLL, I/O bank and peripheral rails are different values. A 5 V power input is not a 5 V-tolerant FPGA GPIO specification. Obtain the actual schematic before attaching Arduino-style circuits, LCDs or another carrier.
- Plan configuration and debug: distinguish transient SRAM configuration via JTAG from programming an EPCS/nonvolatile boot device via supported active-serial tools. Confirm ten-pin JTAG wiring, header orientation, download adapter inclusion, bitstream type and power-on boot behavior.
- Verify project reproducibility: secure revision-specific pin constraints, schematic, memory timing, Quartus version, IP/tool licenses, driver support and sample design for the selected board. Supplier-hosted links and shipping claims are not proof that documentation or every accessory arrives with each variant.
Frequently asked questions
Is the “USB Blaster” selection in an EP4CE6 product a Cyclone IV board? No. Its Color option names a downloader separately from EP4CE6 and EP4CE10 cores.
Does “EP2C5T144C8N Chip” include oscillator, flash and headers? The chip option must not be treated as the module; choose the module variant if an assembled minimum system is required.
Do all EP4CE10 teaching kits include camera and Ethernet modules? No. The itemized six-bundle listing assigns different external modules to different bundles; bundle1 lists only board, programmer and cable.
Is an EPM570 board an FPGA, and is its programmer included? EPM570 is a MAX II CPLD; that offer lists a board only and says a USB Blaster is required.
Does a 2.5 V headline mean a 2.5 V external supply? Not necessarily. Verify the board's input specification against its regulators and I/O-bank rails.
Does JTAG loading permanently retain my design? Do not assume so. Loading a volatile FPGA configuration differs from writing a compatible nonvolatile configuration memory.
Will a ten-pin JTAG cable work with any Altera board? Matching connector dimensions alone is insufficient. Confirm keyed pinout, voltage reference, programmer and Quartus device support.
Specifications above reflect the individual catalog descriptions and are not verified ratings for every item. Supplier statements about quality, return eligibility, shipping, certifications and universal compatibility do not replace Yoeruyo's store policies or the manufacturer datasheets. The selected variant and documented PCB revision govern the actual order and design fit.
