EP4CE6E22I7N - Cyclone IV E FPGA 6K LEs 91 I/O | Intel
MPN: EP4CE6E22I7N ✓ AktifEP4CE6E22I7N Ringkasan
An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose digital logic functionality is defined by the user via a hardware description language and configuration bitstream, rather than fixed at the factory. Positioned in the system hierarchy, FPGAs sit between programmable microcontrollers (software-driven, lower throughput) and application-specific integrated circuits (ASICs, fixed-function, higher NRE). The Cyclone IV E family specifically targets cost-sensitive, high-volume applications where ASIC-like density is unnecessary but microcontrollers cannot meet parallelism, throughput, or custom I/O requirements. Within Intel's FPGA portfolio, the Cyclone IV E sits below the Cyclone 10 LP and MAX 10 families in logic density but shares the same Quartus Prime design toolchain.
Key features of the EP4CE6E22I7N include 6,272 logic elements (4-input LUT4 architecture), 270 Kbits embedded RAM supporting true dual-port, single-port, shift-register, and ROM modes, 91 user I/O pins, two PLLs, 4 Kbits of user flash memory for non-volatile configuration or data storage, and support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL. The device supports serial configuration via EPCS flash or JTAG and includes a global clock network supporting up to 20 clock pins.
Architecturally, the Cyclone IV E series uses 4-input look-up tables (LUT4) as the basic logic element, with each LE containing a register and dedicated carry chain logic for arithmetic operations. The 144-pin EQFP package provides a thermal pad that can be soldered to PCB copper to reduce theta_JA and improve heat extraction for high-toggle-rate designs approaching the maximum operating frequency.
Typical applications include industrial motor control, video processing bridges, low-cost ASIC prototyping, LED display controllers, and consumer electronics interfaces. The wide operating temperature range makes the I7N grade suitable for industrial control and factory automation environments.
When designing with this FPGA, plan for a configuration source (EPCS flash or JTAG), adequate decoupling on each VCCINT/VCCIO rail (0.1 uF ceramic per pin plus bulk capacitance), and thermal management for designs approaching the maximum toggle rate.

Video Processing Bridge
The EP4CE6E22I7N's LVDS I/O support and 270 Kbits of dual-port RAM make it suitable for video format conversion bridges between cameras, displays, and processors. The 4-input LUT4 architecture can implement parallel pixel pipelines at common video rates (720p, 1080p) when clocked appropriately. The 91 user I/Os accommodate multi-lane LVDS pairs and parallel RGB buses. With two PLLs, the FPGA can derive pixel clocks from various input reference frequencies while maintaining jitter performance for clean video output. Industrial temperature rating supports outdoor kiosk and digital signage deployments.
Direkomendasikan
Low-Cost ASIC Prototyping
The EP4CE6E22I7N provides an affordable platform for ASIC prototyping and design verification before committing to NRE mask charges. The 6,272 LEs support mid-complexity ASIC RTL, and the Quartus Prime toolchain offers synthesis from standard HDL (Verilog/VHDL) with timing-accurate simulation. Designers can validate functional correctness and timing margins on actual silicon, then migrate the verified design to a lower-cost ASIC or structured ASIC for volume production. The 144-pin EQFP package is hand-solderable for prototype boards, simplifying hardware bring-up.
Direkomendasikan
LED Display Controllers
The EP4CE6E22I7N drives large LED matrix displays, scrolling signs, and architectural lighting installations where per-channel PWM control and high refresh rates are required. Its 91 user I/Os can drive multiple LED driver chains simultaneously, while the embedded M9K RAM blocks buffer pixel data for smooth animation. The two PLLs generate precise timing references for LED multiplexing schemes, and the LVDS support enables high-speed pixel data transfer from upstream video sources. The I7 industrial temperature grade accommodates outdoor display enclosures without active cooling.
Direkomendasikan
Consumer Electronics Interfaces
The EP4CE6E22I7N serves as a flexible interface bridge in consumer electronics where multiple protocols (I2C, SPI, UART, GPIO, custom) must be aggregated and translated. The 6K LEs handle protocol state machines and FIFO buffers, while 91 I/Os accommodate multiple connector pinouts. The on-chip 4 Kbits of user flash memory stores non-volatile configuration parameters (e.g., device addresses, calibration values). The low unit cost at volume ($11.85 at 3,000 pieces) makes the part attractive for cost-sensitive consumer products such as smart home hubs, AV receivers, and gaming peripherals.
Direkomendasikan
Test and Measurement Instrumentation
The EP4CE6E22I7N supports custom test and measurement fixtures where flexible digital pattern generation, protocol capture, and signal conditioning are required. Its 91 user I/Os interface with DUT (device-under-test) boards via pogo pins or connectors, while the embedded RAM captures waveform traces for offline analysis. The two PLLs synthesize arbitrary clock frequencies for protocol exercisers, and the LVDS I/O support enables high-speed serial protocol testing. The industrial temperature grade ensures reliability in production test environments with variable ambient conditions.
Direkomendasikan
Industrial Communication Gateways
The EP4CE6E22I7N implements protocol conversion gateways between industrial fieldbuses (Modbus, CAN, RS-485, Profibus) and Ethernet/IP networks in factory automation. Its 6,272 LEs handle multiple concurrent protocol stacks with deterministic timing, while the LVDS-capable I/Os support high-speed industrial Ethernet PHYs. The 270 Kbits embedded RAM provides buffering for message queues between bus segments. The -40C to +100C industrial temperature grade, combined with low power consumption, suits DIN-rail mounted controllers in 24/7 factory operations.

Catatan Desain
Cyclone IV E devices require multiple supply rails: VCCINT (1.0-1.2 V core), VCCIO (1.5/1.8/2.5/3.3 V per I/O bank), VCCA (analog PLL supply, typically 2.5 V), and VCCD_PLL (PLL digital supply). Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 3 mm of the pin, plus a 10-100 uF bulk capacitor near the FPGA. Each VCCIO bank requires its own decoupling network sized to the I/O toggle rate. Power sequencing must follow the manufacturer datasheet ordering to avoid latch-up.
Estimated: at maximum toggle rate (e.g., 200 MHz on 60% of pins, LVCMOS 3.3 V), the EP4CE6E22I7N in the EQFP-144 package may dissipate 0.8-1.5 W. The exposed thermal pad on the bottom of the EQFP package must be soldered to a PCB thermal land connected to an inner ground plane with thermal vias (typically 4-9 vias, 0.3 mm drill). Without thermal pad soldering, junction temperature can exceed 100C in high-utilization designs. Verify thermal margin in worst-case design utilization with Quartus PowerPlay early in the design cycle.
Cyclone IV E FPGAs are sensitive to PCB layout for high-speed LVDS and DDR interfaces. Route differential pairs with 100 ohm controlled impedance, match trace lengths within 150 mil for LVDS, and keep reference planes continuous under high-speed traces. Use a 4-layer PCB stackup with dedicated ground and power planes; avoid routing over plane splits. For JTAG configuration, route TCK with a 33 ohm series termination and keep TMS/TDI/TDO short to minimize noise coupling.
Do not leave unused I/O pins floating - configure them as outputs driving low or as inputs with internal weak pull-ups in the Quartus pin assignment file. Floating inputs can oscillate and draw excessive current. When migrating from EP4CE6E22C8N (commercial) to EP4CE6E22I7N (industrial), verify timing closure still meets margins since speed grades differ. For 10+ year service life products, consider Cyclone 10 LP (10CL025) migration as the Altera Community thread indicates Cyclone IV E supply tightness.
