EP4CE22E22C8N - 22K-Element Cyclone IV E FPGA | Altera
MPN: EP4CE22E22C8N ✓ Hoạt độngEP4CE22E22C8N Tóm tắt
A field-programmable gate array, or FPGA, is a programmable digital integrated circuit whose internal logic blocks, interconnect, memory, and I/O can be configured after manufacture. FPGA devices occupy the hierarchy FPGA and CPLD, programmable-logic device, digital semiconductor, and programmable electronics. This programmability enables parallel hardware implementations of control, signal-processing, communication, and data-acquisition functions without changing the PCB for each logical revision.
The supplied specifications identify a 472.5 MHz speed grade, 22,320 logic elements, 79 I/Os, and 608,256 memory bits. The E22 package is a 144-LQFP exposed-pad configuration, with an exposed thermal pad intended to improve heat transfer from the device. Its 1.15 V to 1.25 V core voltage range places it in the low-voltage digital-logic domain. Detailed logic-cell composition, RAM organization, PLL count, pin directions, and absolute timing limits are not included in the verified data and therefore require manufacturer-datasheet review.
Typical uses include industrial control, communications, instrumentation, embedded automation, and general-purpose digital logic. Its 22,320 logic elements make it suitable for designs requiring substantially more parallel processing than a basic small microcontroller while remaining within the Cyclone IV E low-cost FPGA family. The 79 I/Os provide external interfaces for sensors, converters, displays, communications transceivers, and control signals, although exact bank voltage limits and I/O standards must be checked in the datasheet.
A critical design consideration is power integrity. The 1.15 V to 1.25 V core rail must be supplied with low-noise decoupling, and all banks must be configured only with compatible supply voltages and I/O standards. The 144-LQFP exposed-pad footprint requires careful solder assembly and adequate thermal-copper layout. Programming, configuration, initialization, clocking, and unused-pin behavior should follow Altera's device documentation.
This page consolidates the verified distributor and manufacturer-page facts for EP4CE22E22C8N and separates available specifications from missing engineering data. It also records pricing evidence, sourcing references, package identity, and design questions that should be resolved from the complete Cyclone IV E documentation before schematic release or production use.

Ứng dụng tiêu biểu
EP4CE22E22C8N phù hợp cho 6 Áp dụngs: Industrial Control Logic, Communications Interface, Data Acquisition, Instrumentation and Test Equipment, Embedded Automation, Embedded Networking.
Industrial Control Logic
The EP4CE22E22C8N fits industrial control systems requiring deterministic parallel logic, programmable state machines, and multiple external interfaces. Its 22,320 logic elements can host control sequencing, interlocks, counter logic, and protocol handling, while 79 I/Os connect discrete sensors, actuators, relays, and status indicators. The 1.15 V to 1.25 V core range suits a modern digital subsystem, but the complete bank-voltage and I/O-standard requirements must come from the datasheet. Designers should validate timing margin, power sequencing, industrial temperature requirements, and long-term supply availability before production release.
Được đề xuất
Communications Interface
EP4CE22E22C8N can implement programmable communication interfaces when a design needs parallel serialization, framing, filtering, or custom timing rather than a fixed controller function. The 79 I/Os provide a substantial external interface budget, and the 472.5 MHz listed speed rating can support timing-critical logic when the design meets its specified conditions. Actual usable baud rate, I/O standard, PLL configuration, and timing closure depend on the selected pins and complete device data. Signal-integrity work should include controlled-impedance routing, termination, and grounded return paths.
Được đề xuất
Data Acquisition
The EP4CE22E22C8N is appropriate for digital front-end logic around sensors, converters, and data-capture systems. Its programmable architecture can implement parallel capture, channel multiplexing, trigger handling, filtering, and interface timing, while 608,256 embedded memory bits provide on-chip storage where the design requires buffering. The verified data does not specify converter input standards or memory-port timing, so analog front-end selection remains a separate design task. Validate acquisition timing, input thresholds, clocking, and signal integrity at the exact operating voltage and package footprint.
Được đề xuất
Instrumentation and Test Equipment
EP4CE22E22C8N can support programmable instrumentation front ends that coordinate measurement sequencing, digital calibration, status reporting, and data paths. The 22,320 logic elements provide room for parallel control functions, while the 79 I/Os support displays, switches, triggers, converters, and communications. The listed 472.5 MHz speed rating should not be interpreted as a guaranteed timing closure without pin-specific constraints and design compilation. Use the exposed pad with a stable thermal design, follow the manufacturer's recommended decoupling, and validate every external interface for voltage tolerance and signal integrity.
Được đề xuất
Embedded Automation
The EP4CE22E22C8N suits embedded automation designs that require flexible hardware timing, parallel I/O, and programmable logic close to sensors and actuators. A typical implementation could combine motion-sequence timing, limit-input decoding, step-control logic, and communication buffering without placing every function in a microcontroller. The 79 I/Os are valuable for distributed connections, while the low-voltage core supports integration into a modern embedded board. Confirm motor-drive isolation, output levels, timing margins, thermal exposure, and functional-safety requirements with the complete device documentation.
Được đề xuất
Embedded Networking
EP4CE22E22C8N can be used for hardware-assisted networking functions such as traffic classification, frame manipulation, buffering, and protocol preprocessing. Its 22,320 logic elements and 608,256 memory bits allow a compact parallel implementation, while 79 I/Os support connections to network PHYs and control processors. The design must account for the exact I/O standards, voltage domains, clock requirements, and timing paths of the selected board. Use short, impedance-controlled routes for high-speed signals and validate operation with the target PHY, clock source, and networking software or hardware control plane.

Bảo phân biệt quan trọng
- Higher verified logic-element class than EP4CE10 comparison candidates (vsEP4CE10E22C8N)
- Closer EP4CE22 family identity than lower-resource EP4CE10 candidates (vsEP4CE10E22C8LN)

Ghi chú thiết kế
The verified core-supply range is 1.15 V to 1.25 V. Confirm the exact core, I/O, auxiliary, and configuration supply requirements in the manufacturer datasheet before laying out the power tree. Place the required bulk and high-frequency decoupling capacitors close to the corresponding supply and ground pins, and provide a low-impedance ground plane so transient current from the FPGA does not corrupt I/O references.
The EP4CE22E22C8N is supplied in a 144-LQFP exposed-pad package. Treat the exposed pad as both an electrical connection and a thermal path: follow the package drawing for its permitted connection, preserve solder wicking control during assembly, and provide as much uninterrupted copper as practical. Exact power dissipation and junction-temperature limits are not in the verified data, so use the manufacturer thermal information rather than an assumed wattage limit.
Do not infer a pinout from the 144-pin package count. Obtain the exact EP4CE22E22C8N package pin table before assigning power, ground, configuration, clock, or user I/O. Keep sensitive clock and high-speed interface routes short, use controlled-return paths, and separate noisy switching or external clock sources from precision analog and communication interfaces. Validate all I/O standards and voltage domains in the tool and schematic review.
The comparison search results do not prove that EP4CE22E22C6N, EP4CE10E22C8N, or EP4CE10E22C8LN is drop-in compatible. Differences in resource class, ordering suffix, speed grade, temperature grade, or supply requirements can affect timing, power, and pin compatibility. Require a complete datasheet comparison and a successful hardware validation before substituting any related Cyclone IV E MPN.
Thông tin tuân thủ
The supplied verified results identify the device and package but do not provide authoritative RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than inferred from the family or distributor listings.
