EP4CE22E22C7N - 22K-Element Cyclone IV E FPGA | Altera
N.º de pieza: EP4CE22E22C7N ✓ ActivoEP4CE22E22C7N Descripción general
A field-programmable gate array, or FPGA, is a programmable semiconductor in the broader logic-device and digital-signal-processing hierarchy. Its configurable logic, embedded memory, and I/O resources can be programmed to implement control logic, communication interfaces, data acquisition functions, and other parallel digital systems. The Cyclone IV E name identifies Altera's device family, while E22 identifies the resource configuration of this ordering part number.
The EP4CE22E22C7N's principal resource figures are 22,320 logic elements, 608,256 memory bits, and 79 I/Os. These figures determine the amount of parallel logic and on-chip storage available to a design. Its 144-pin LQFP exposed-pad package supports standard surface-mount assembly and provides 144 physical terminals for power, configuration, clock, user I/O, and other device functions.
The device belongs to the Cyclone IV E family, which Altera positions as a low-cost, low-power FPGA platform. Logic capacity makes the E22 configuration appropriate for control-oriented embedded designs, while embedded memory supports local data buffering and stateful sequential functions. User I/O provide interfaces between the programmable core and external circuits, allowing the same FPGA family to serve industrial control, communications, instrumentation, and embedded processing systems.
Typical applications include programmable logic controllers, industrial automation controllers, test and measurement instruments, communication interface modules, embedded system control, and sensor data-acquisition paths. The device can be selected when a fixed-function controller cannot provide the required combination of parallel logic, configurable I/O, and design flexibility. Firmware and configuration resources should be checked against the final system architecture before deployment.
A key design consideration is the exposed thermal pad. The pad should be connected to the appropriate power or ground plane according to the manufacturer's pin-assignment and layout guidance, with careful via placement to preserve signal integrity and thermal performance. Board-level requirements for supply rails, clocking, configuration, decoupling, and I/O standards must follow the EP4CE22 datasheet.
This product record combines the ordering-code identity, resource configuration, package details, and engineering selection criteria with practical application and PCB guidance. It also distinguishes verified same-family ordering options from unsupported cross-brand substitutions, helping engineers evaluate the E22C7N without treating merely similar FPGAs as drop-in replacements.

Aplicaciones típicas
EP4CE22E22C7N es adecuado para 6 aplicacións: Industrial Automation Controller, Programmable Logic Controller, Test and Measurement Front End, Sensor Data Acquisition, Communication Interface Module, Embedded System Control and Signal Conditioning.
Industrial Automation Controller
The EP4CE22E22C7N fits industrial automation controllers that combine sequential control, parallel signal processing, and configurable external interfaces. Its 22,320 logic elements can implement state machines and control logic, while 608,256 bits of embedded memory support buffering and parameterized data handling. The 79 user I/Os provide connections for sensors, actuators, interlocks, and communications. In a controller, the FPGA could sit beside a microcontroller and handle high-speed input sampling, pulse conditioning, timing, and protocol conversion. The 144-pin LQFP exposed-pad package also requires a carefully designed land pattern and exposed-pad connection. Final industrial suitability depends on the required operating temperature, I/O voltage domains, clock rate, and applicable machine-safety requirements.
Recomendado
Programmable Logic Controller
The EP4CE22E22C7N is appropriate for a programmable logic controller requiring deterministic parallel I/O, configurable logic, and local data storage. Its 22,320 logic elements provide capacity for state machines, interlocks, counters, timers, and communication interfaces, while the 608,256 memory bits can hold working state and sampled data. The 79 user I/Os can support discrete inputs, relay outputs, encoder interfaces, and field-bus signaling when their voltage and timing requirements match the design. Compared with a fixed microcontroller, the FPGA permits parallel work and deterministic sequencing. Compared with a larger FPGA, it offers a more compact resource level for control-oriented logic. Clock constraints, I/O standards, configuration scheme, and exposed-pad layout should be established from the EP4CE22 family documentation.
Recomendado
Test and Measurement Front End
The EP4CE22E22C7N can implement programmable front-end logic in test and measurement equipment, including counters, trigger conditioning, sequencing, result capture, and interface control. Its 79 user I/Os provide connections to external sensors and test fixtures, while 22,320 logic elements support parallel acquisition pipelines and 608,256 memory bits provide on-chip buffering. The FPGA is particularly useful when multiple channels must be sampled, filtered, or compared concurrently under deterministic control. A practical implementation would distribute clocking carefully, assign I/O to the required voltage domains, and define timing constraints for every external interface. The 144-pin LQFP exposed-pad package also requires thermal and power-plane attention. Analog precision, bandwidth, and measurement uncertainty remain separate system specifications rather than direct FPGA performance figures.
Recomendado
Sensor Data Acquisition
The EP4CE22E22C7N supports parallel sensor data-acquisition designs that combine acquisition sequencing, filtering, and data transfer. The 22,320 logic elements can implement sampling control and real-time processing, while the 608,256 memory bits offer local storage for transient or buffered data. Its 79 user I/Os give designers access to multiple sensors, triggers, status signals, and communication interfaces. In an acquisition card, the FPGA could coordinate multiplexers, coordinate analog-to-digital converters, timestamp samples, and package results for transmission to a host processor. The exact implementation depends on the converter interface, sample rate, channel count, and clocking topology. Input thresholds, I/O standards, and timing margins must be checked in the EP4CE22 datasheet, while the exposed pad requires a compliant PCB footprint.
Recomendado
Communication Interface Module
The EP4CE22E22C7N is suitable for communication modules that require parallel protocol conversion, framing, buffering, and host interfacing. The 22,320 logic elements can support multiple concurrent channels, while 608,256 bits of embedded memory can hold packet data, descriptors, or status information. Its 79 user I/Os can carry byte-wide buses, clock signals, chip selects, and interrupt or status lines. The FPGA is useful when a system needs programmable framing or a migration path between serial and parallel interfaces without relying on a fixed-function bridge. Design work should account for the selected I/O voltage, maximum interface clock, clock-domain crossing, and timing closure. Because the ordering code encodes device options, confirm that any EP4CE22E22 alternative is qualified for the same board, temperature, and timing requirements.
Recomendado
Embedded System Control and Signal Conditioning
The EP4CE22E22C7N can serve as a dedicated control and signal-conditioning element beside an application processor or microcontroller. Its programmable logic can normalize sensor signals, isolate timing domains, debounce inputs, generate precision triggers, and implement redundant interface paths. The 79 user I/Os make it useful for systems combining many digital lines, while 608,256 memory bits provide a local working buffer and 22,320 logic elements support concurrent control functions. The device can divide work between fixed software and hardware by moving repetitive or timing-critical operations into the FPGA. Practical deployment requires careful clock planning, constraints for every I/O path, and review of configuration and power-up behavior. Its exposed-pad LQFP package must also be laid out with appropriate thermal and electrical treatment on the PCB.

Notas de diseño
Implement the 144-pin LQFP exposed-pad footprint exactly from the Altera package drawing, including land length, width, solder-mask relief, and exposed-pad dimensions. Place the exposed-pad vias in the manufacturer-recommended pattern so thermal conduction and electrical connection are established without interfering with high-speed signal routing. Confirm whether the pad is connected to a specified supply or ground plane for this ordering code before PCB release.
Assign clocks, configuration pins, and user I/O deliberately rather than relying on automatic placement without constraints. Apply clock-domain and timing constraints to every interface, and reserve short, continuous routing for high-fanout or timing-sensitive signals. Because the device includes 79 user I/Os in a 144-terminal package, several pins also carry power or configuration functions; use the pin-description table when planning breakout headers and test points.
Do not treat EP4CE22E22C7, EP4CE22E22C8, and the target as automatically equivalent merely because they share the EP4CE22 E22 prefix. Their ordering suffixes encode different device options, so compare timing grade, temperature grade, and exact package details before substituting. A valid replacement must preserve the PCB footprint, pin functions, supply requirements, configuration method, and all system timing constraints.
Información de cumplimiento
The ordering-information listing names JESD-609 and moisture-sensitivity fields but does not expose their values. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status are therefore recorded as unknown.
