EP4CE6E22C8 概要

The Intel (formerly Altera) EP4CE6E22C8 is a low-power, low-cost Cyclone IV E FPGA featuring 6,272 logic elements, 392 Kbits of embedded memory, and 91 user I/Os in a 144-pin EQFP (E22) package. The Cyclone IV E family is optimized for high-volume, cost-sensitive applications that require transceiver-less connectivity, with a 1.2V core supply and a maximum internal clock frequency of approximately 472.5 MHz. The 'C8' speed grade indicates a -8 corner commercial speed bin, while the 'E22' suffix denotes the EQFP-144 package (22 mm x 22 mm body, 0.5 mm pitch).

A Field Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic in silicon via HDL code and an on-chip configuration bitstream. Within the broader hierarchy, FPGAs belong to the programmable logic device (PLD) family, which sits alongside microcontrollers, DSPs, and ASICs as a programmable computing fabric. Cyclone IV E specifically targets applications where low static power, low unit cost, and non-transceiver I/O density matter more than the highest possible logic throughput.

Key features of the EP4CE6E22C8 include two PLLs for clock synthesis, up to 15 embedded 18x18 multipliers for DSP arithmetic, configuration support via JTAG and active serial (EPCS) flash, and commercial temperature-grade operation (0C to +85C junction). The EQFP-144 package provides 91 general-purpose I/Os across eight I/O banks, supporting LVDS, LVCMOS, SSTL, and other common single-ended and differential I/O standards used in industrial and consumer designs.

Cyclone IV E devices are built on a 60 nm process and use a logic-array block (LAB) architecture with 16 logic elements per LAB, an embedded memory block array, and routing switch matrices. Configuration bitstreams are typically loaded from an external EPCS serial flash or through the JTAG port, and the device retains configuration as long as core power is maintained. The Cyclone IV E family supports Nios II embedded processor cores, allowing engineers to build full soft-core systems on a single chip.

Typical applications include industrial motor control, low-cost video processing, USB and Ethernet bridging, education/DIY development boards (for example the well-known EP4CE6-based Nios II evaluation board from Waveshare), LED display controllers, and consumer electronics glue logic. The wide temperature range and 91 I/O count make it well-suited to small-to-medium logic integration where a microcontroller is too rigid.

When designing with this device, verify that the I/O bank voltage rails match the signaling levels of any external memories or peripherals, and place decoupling capacitors (0.1 uF and 10 uF) close to every VCCINT and VCCIO pin. For configuration, ensure the JTAG chain length and pull-up resistors follow the Cyclone IV handbook recommendations to avoid programming failures.

This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes beyond what the manufacturer datasheet alone provides.

🏭

Industrial Motor Control

The EP4CE6E22C8 fits industrial motor-control designs because its 6,272 logic elements, 15 embedded 18x18 multipliers, and 2 PLLs are sufficient to implement a single-axis field-oriented controller (FOC), quadrature decoder, and PWM modulator in a single chip. The 91 available I/Os in the EQFP-144 package let designers route Hall/encoder feedback, gate driver signals, and analog feedback simultaneously without external logic. Industrial designers pair the device with external gate drivers and current-sense ADCs; the FPGA absorbs deterministic timing that a microcontroller cannot guarantee. Use the PLLs to derive the high-resolution PWM carrier and the multiplier blocks for the Park/Clarke transforms.

🧩

Education and Nios II Development Boards

The EP4CE6E22C8 is the silicon inside widely used Cyclone IV E learning kits such as the Waveshare CoreEP4CE6. Its 6K logic elements provide enough capacity to instantiate the Nios II soft-core CPU plus peripheral IP (UART, SPI, SDRAM controller, PIO) for full SoC-style labs. The EQFP-144 package at 0.5 mm pitch is hand-solderable for student breakout work, and the JTAG port plus active-serial configuration path are supported by the free Quartus Prime Lite toolchain. Beginners can blink an LED, then progressively add custom accelerators (PWM, VGA, audio) without ever leaving the Cyclone IV E family.

📺

Low-Cost Video Processing

For low-resolution video pipelines, the EP4CE6E22C8 delivers adequate throughput by combining 15 embedded multipliers for chroma upscaling and a generous embedded RAM array (270 Kbits) used as line buffers. The 91 I/Os accept parallel RGB/YUV input from mid-resolution sensors and drive LVDS or LVCMOS outputs to small LCD panels. Compared to a microcontroller, the FPGA handles 60 fps timing deterministically without CPU load. Designers typically pair it with an external SDRAM for frame buffering and an HDMI transmitter for output; the FPGA can absorb format conversion, scaling, and on-screen display overlay.

USB and Ethernet Bridging Gateways

The EP4CE6E22C8 can implement custom USB-to-UART, USB-to-SPI, or Ethernet MAC-to-serial bridges using vendor soft-IP cores. Its 6,272 logic elements and 270 Kbits of embedded RAM are sufficient for a 10/100 Ethernet MAC plus a small RISC-V soft-core running the protocol stack, while the 91 I/Os handle PHY RMII signals, USB data lines, and UART/SPI links to a host MCU. Industrial gateway designers use the FPGA to absorb timing-critical PHY handshakes that would otherwise bog down a microcontroller. The JTAG port allows fast firmware iteration during development.

💡

LED Display and Lighting Controllers

The EP4CE6E22C8 is a strong fit for driving multi-channel LED walls and architectural lighting fixtures because each of its 91 I/Os can be precisely timed with the on-chip PLLs. With 15 embedded multipliers, designers can implement gamma correction and per-pixel color-space conversion in hardware, freeing the host processor from refresh-rate tasks. The EQFP-144 package provides enough I/O density for HUB75 LED panels, DMX512 receivers, and SPI-driven APA102 chains running concurrently. Long-run installations value the FPGA's deterministic refresh rate and its ability to push firmware updates via JTAG in the field.

📱

Consumer Electronics Glue Logic

Consumer products that need custom glue logic between ASICs, sensors, and a host processor benefit from the EP4CE6E22C8's combination of small footprint, low unit cost, and 91 I/Os. Typical designs use it to implement proprietary protocol bridges, sample-rate converters, and timing-skew adjustment between mismatched busses. The 270 Kbits of embedded RAM is enough for small FIFOs that decouple a fast sensor from a slow host, while the 15 embedded multipliers handle lightweight DSP such as FIR filters or tone detection. The JTAG chain simplifies board bring-up for low-volume SKUs.

What is the operating voltage of EP4CE6E22C8?

The EP4CE6E22C8 operates with a 1.2 V core supply (VCCINT) and per-bank I/O voltages (VCCIO) that can be independently set from 1.2 V to 3.3 V. According to the Intel Cyclone IV Device Handbook, the device also requires a 2.5 V or 3.3 V analog PLL supply (VCCA) and a configuration reference voltage for proper operation.

How many logic elements does EP4CE6E22C8 have?

The EP4CE6E22C8 contains 6,272 logic elements organized into 392 logic array blocks (LABs) of 16 LEs each. It also includes 270 Kbits of embedded RAM, 15 18x18 embedded multipliers, and 2 PLLs, providing a balanced resource mix for low-cost programmable logic designs.

What package does EP4CE6E22C8 use and how many I/O pins are available?

The EP4CE6E22C8 is housed in a 144-pin Enhanced QFP (EQFP-144, package code E22) measuring 22 mm x 22 mm with a 0.5 mm lead pitch. Up to 91 of the 144 pins are user I/Os, distributed across eight programmable I/O banks that support LVCMOS, LVTTL, LVDS, SSTL, and other I/O standards.

Where to buy EP4CE6E22C8 online and what is the current price?

The EP4CE6E22C8 is in stock at major distributors including Mouser, DigiKey, and Avnet. As of 2026-09-10, single-unit pricing starts around USD 22.50, with quantity discounts available at 100-piece and 1000-piece breaks (see the tier table on this page). Lead time for production quantities is typically 6 to 12 weeks when ordered direct from Intel.

Is EP4CE6E22C8 in stock at distributors right now?

Distributor stock for the EP4CE6E22C8 is generally available but fluctuates; we recommend checking Mouser and DigiKey in real time before placing an order. For long-lead-time production runs, distributors typically offer scheduled order entry; for prototype needs, smaller distributors such as Ampheo and Avaq also list inventory.

What is the lead time for EP4CE6E22C8?

Standard lead time for the EP4CE6E22C8 from Intel is roughly 8 to 12 weeks for production quantities as of 2026-09-10. Authorized distributors usually stock small quantities for prototype orders with 1-2 week lead time, but high-volume production builds should be scheduled at least 12 weeks in advance to avoid schedule risk.

EP4CE6E22C8 vs EP4CE10F17C8N - which is better for motor control?

For typical motor-control applications, the EP4CE6E22C8 with 6,272 LEs and 91 I/Os is sufficient when implementing a single-axis controller plus quadrature decoder. If your design needs additional logic capacity for multi-axis control, Ethernet stacks, or larger DSP filter chains, the EP4CE10F17C8N (10,320 LEs, 182 I/Os, FBGA-256) is the better fit, but note the package change requires PCB redesign.

What is the difference between EP4CE6E22C8 and EP4CE6E22C7?

The EP4CE6E22C8 and EP4CE6E22C7 share identical EQFP-144 (E22) packaging and the same 6,272 logic elements, but differ in speed grade. The C8 part is approximately 15% faster than the C7 in timing closure, allowing higher fMAX in critical paths. Both parts are drop-in pin compatible, so a C7 design can be qualified up to a C8 part without any PCB changes.

What is the best drop-in replacement for EP4CE6E22C8?

The best drop-in replacement for EP4CE6E22C8 within the Cyclone IV E family is the EP4CE6E22C7N (slower speed grade, same EQFP-144 footprint), or the EP4CE6E22A7N (lower power A-speed grade in the same package). Both share pin compatibility with the EP4CE6E22C8 and are appropriate substitutes when C8 inventory is constrained.

Can EP4CE6E22C6 replace EP4CE6E22C8 directly?

Yes, the EP4CE6E22C6 is pin-to-pin drop-in compatible with the EP4CE6E22C8 in the same EQFP-144 (E22) package. The C6 speed grade is the slowest in the family (about 25% slower than C8), so timing closure must be re-validated, but the schematic and PCB layout are unchanged.

When should I choose EP4CE6E22C8 over EP4CE10E22C8N?

Choose the EP4CE6E22C8 when your design fits within 6,272 LEs, 270 Kbits of RAM, and 91 I/Os - this keeps unit cost at the lowest level in the family. Move to the EP4CE10E22C8N (10,320 LEs, 414 Kbits RAM, 92 I/Os) only when you need extra logic headroom for added features; note that the E22 package is shared, so the PCB layout does not need to change.

Is the EP4CE6E22C8 suitable for a learning / development board?

Yes, the EP4CE6E22C8 is widely used on university and DIY development boards such as the Waveshare CoreEP4CE6. Its 6K LEs and 91 I/Os are large enough for Nios II soft-core CPU labs, video processing tutorials, and small RISC-V cores, while the EQFP-144 package is hand-solderable on breakout boards with 0.5 mm pitch.

Where can I download the EP4CE6E22C8 datasheet PDF?

The official EP4CE6E22C8 datasheet (Cyclone IV Device Handbook, Volume 1) is published by Intel and can be downloaded from https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-iv/cyiv-51001.pdf. Mirror copies are also available on third-party sites such as alldatasheet.net and octopart.com.

Where can I find the EP4CE6E22C8 pinout?

The official pin information table for the EP4CE6 (E22 / EQFP-144) package is published by Intel as the 'Pin Information for the Cyclone IV EP4CE6 Device' PDF, accessible from the Intel content-details page at https://www.intel.com/content/www/us/en/content-details/655836/pin-information-for-the-cyclone-iv-ep4ce6-device-pdf-format.html.

What is the best cross-brand equivalent for EP4CE6E22C8?

Intel Cyclone IV E parts are not directly drop-in replaceable by other vendors' FPGAs because the configuration bitstream, JTAG pinout, and I/O bank assignments differ. For cross-brand migration of similar logic capacity, consider Lattice Semiconductor's ECP5 or iCE40 families (32K-84K LEs), but these require a complete board redesign plus recompilation with vendor-specific toolchains.

Choose the EP4CE6E22C8 when your design fits within 6,272 logic elements, 270 Kbits of embedded RAM, and 91 user I/Os, and you need the fastest speed grade (C8) in the EP4CE6 E22 family for tightest timing closure. Pick the EP4CE6E22C7 or EP4CE6E22C6 if you want a drop-in slower speed grade for cost-down or inventory reasons. Step up to the EP4CE10E22C8N when logic capacity exceeds 6K LEs but you still want to stay in the EQFP-144 footprint; only move to a different package (for example EP4CE10F17C8N in FBGA-256) when you also need higher I/O density or transceivers. All five MPNs listed above are pin-compatible drop-in alternatives in the same EQFP-144 (E22) package.

設計ノート

The EP4CE6E22C8 requires four distinct power rails: VCCINT = 1.2 V for the core, VCCIOx = 1.2 V to 3.3 V per I/O bank, VCCA = 2.5 V for the analog PLL blocks, and VCCPD for the configuration I/Os. Decouple every VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add one bulk 10 uF capacitor per supply plane. Sequencing is recommended so that VCCINT ramps before VCCA, per the Cyclone IV handbook. Estimated: for a typical 25 percent utilization design the static current is on the order of 50 mA, with dynamic current dominated by switching I/O toggling.

The EQFP-144 package has 0.5 mm lead pitch, which is at the practical limit for hand-soldering and demands careful PCB footprint design. Use a land pattern with 0.30 mm wide copper pads and 0.50 mm pitch; route escape traces on inner layers between the pads using dog-bone fanout. Provide a continuous ground plane on layer 2 to control return paths for high-speed I/O such as LVDS pairs. Power planes should be solid copper for VCCINT and split for VCCIO banks to avoid SSN (simultaneous switching noise).

A common mistake is leaving MSEL pins floating; the EP4CE6E22C8 requires MSEL0/MSEL1/MSEL2 to be tied to GND or VCCPD to select the active-serial (EPCS) or JTAG configuration mode - leaving them floating causes configuration failure. Another pitfall is connecting JTAG TCK to a slow signal that violates the 10 ns minimum rise/fall time, which produces unreliable programming. Lastly, when migrating from the EP4CE6E22C8 to the C7 or C6 speed grade, do not assume timing closure is automatic - re-run the TimeQuest timing analyzer because worst-case path delays differ.
