An FPGA (field-programmable gate array) is a reconfigurable integrated circuit whose logic fabric is programmed after manufacturing using an HDL bitstream, placing it in the programmable logic device branch of the integrated-circuit hierarchy. Within that hierarchy, the Cyclone family is an entry-level, cost-optimized FPGA product line intended for low- to mid-density glue logic, I/O expansion and controller tasks. The EP1C3 sits near the low end of the Cyclone range, making it useful for designs needing modest logic and I/O resources without moving to large SoC-class FPGAs.
Key verified specifications include 2910 logic elements divided into 291 LABs/CLBs, 59,904 total RAM bits, 104 user I/O pins, a core supply range of 1.425 V to 1.575 V, and an operating junction temperature range of 0 °C to 85 °C. The device is supplied in a 144-pin LQFP package with surface-mount packaging in tray media, and its verified product status is Obsolete on several distributor listings. The high I/O-to-logic ratio makes this part especially suitable for pin-intensive control and interface designs.
The Cyclone architecture groups logic into LABs and embeds memory blocks in the same die, allowing state machines, small FIFOs and simple processors to be implemented in a single device. Because the part is SRAM-based, it must be configured at every power-up from an external configuration source. The 104 I/O pins can support parallel buses, low-speed serial interfaces and discrete control lines, while the 1.425 V to 1.575 V core supply reflects an early low-voltage FPGA power rail.
Typical uses for the EP1C3T144C8GA include industrial control I/O, protocol bridging, display glue logic, medical monitoring front-end logic, IoT edge signal conditioning, and replacement of legacy programmable logic. With 2910 logic elements, designers can fit PID controllers, quadrature decoders, UART/SPI/I2C bridges and small custom peripherals. The commercial 0 °C to 85 °C junction rating covers most indoor and industrial cabinet environments, although extended-temperature applications should use an industrial-grade variant.
When designing with this FPGA, carefully decouple the 1.425 V to 1.575 V core rail and provide a dedicated configuration clock and configuration device. Verify the exact 144-pin LQFP pin mapping from the manufacturer datasheet before laying out the PCB, because the verified web data does not reproduce the full pin table. The GA suffix and ordering code should also be validated against your assembly supplier’s RoHS or lead-free requirements.

典型應用
EP1C3T144C8GA 適用於 6 應用s: Industrial I/O and Motor Control, Communication Protocol Bridging, Display and Video Interface Glue Logic, Medical Monitoring Front-End Logic, IoT Sensor Gateway, Legacy System Replacement / FPGA Migration.
Industrial I/O and Motor Control
The EP1C3T144C8GA suits industrial I/O and motor-control logic because it supplies up to 104 user I/O pins for sensors, encoders, switches and PWM outputs while providing 2910 logic elements for state machines and fault handling. The verified 0 °C to 85 °C junction temperature range is adequate inside an industrial cabinet with airflow, and the 1.425 V to 1.575 V core rail is typical of an early low-voltage FPGA family. With 59,904 RAM bits, small FIFOs for encoder counts or UART buffering can be implemented on-chip. For production substitutions, all EP1C3T144 variants share the same package and logic resources, so speed-grade or industrial-temperature changes do not require a new PCB. Use a configuration flash device at power-up because the Cyclone fabric is SRAM-based and does not retain logic content when power is removed.
推薦
Communication Protocol Bridging
The EP1C3T144C8GA is useful as a communication protocol bridge because its 104 user I/O pins can connect to parallel microcontroller buses, UART transceivers, SPI/I2C devices and simple custom parallel interfaces. The 2910 logic elements provide enough fabric to implement FIFOs, protocol state machines, clock-domain crossing logic and register-based command interfaces. The 59,904 RAM bits allow modest packet buffering without adding external SRAM, which is valuable in cost-sensitive industrial networking modules. Designers working in the 1.425 V to 1.575 V core world must pay attention to I/O bank supply rails and level shifting when bridging to legacy 5 V peripherals. Because no cross-brand pin-compatible replacement was found in the cross-reference data, using another EP1C3T144 speed-grade variant is the fastest way to maintain supply-chain flexibility.
推薦
Display and Video Interface Glue Logic
The EP1C3T144C8GA can implement display and video interface glue logic when the design needs parallel RGB or LVDS timing generation, scan-line counters, pixel-clock domain crossing or simple frame-buffer address generation. Its 2910 logic elements are enough for these control-focused tasks, while 104 I/O pins connect to source drivers, frame buffers and host processors. The 59,904 RAM bits can hold small line buffers or look-up tables, reducing external memory demand in low-resolution display applications. Commercial temperature operation of 0 °C to 85 °C fits monitors, kiosks, and indoor signage. The 144-LQFP package provides a practical pin count for a 24-bit RGB bus plus control signals. Always verify each pixel-clock and data pin against the official datasheet pin table before PCB layout.
推薦
Medical Monitoring Front-End Logic
In medical monitoring devices, the EP1C3T144C8GA can handle front-end control and interface logic for analog-to-digital converters, sensor multiplexing, alarm state machines and host-communication protocol glue. Its 104 user I/O pins allow direct connection to multiple ADC channels, status LEDs and isolated UART interfaces, while 2910 logic elements are suitable for low-latency threshold detection and averaging filters. The 0 °C to 85 °C operating range is typical for room-temperature medical electronics in a controlled enclosure. Although this FPGA is not presented as an AEC-Q100 or medical-certified component, the device-level electrical behavior can be validated in a system qualification if the overall medical product meets applicable safety standards. For cost-sensitive designs, selecting an EP1C3T144 variant already in your supply chain reduces second-source qualification effort.
推薦
IoT Sensor Gateway
The EP1C3T144C8GA is appropriate for an IoT sensor gateway when the gateway needs deterministic parallel sensor sampling, protocol conversion and pre-processing before handing data to a host processor. The 104 I/O pins connect to multiple temperature, pressure, current and digital sensors, while 2910 logic elements can implement rotating priority controllers, timestamp wrappers and 1-Wire or SPI protocol engines. The 59,904 RAM bits provide small queues for bursty sensor data, lowering host interrupt load. Because the core supply is 1.425 V to 1.575 V, the FPGA is best paired with a compatible 1.5 V power rail generated by a regulator on the gateway board. Its commercial temperature range is acceptable for indoor IoT gateways and edge computers but not for outdoor unattended enclosures unless the enclosure is climate controlled.
推薦
Legacy System Replacement / FPGA Migration
The EP1C3T144C8GA can serve as a legacy system replacement or FPGA migration target when an older programmable logic design is being moved to a 144-pin LQFP FPGA with a known public package. The verified logic resources of 2910 elements, 59,904 RAM bits and 104 I/O are sufficient for many legacy PLD/FPGA conversions, and because multiple EP1C3T144 speed-grade variants share the same footprint, a single PCB design can support C8, C7N and C6N parts. This approach is especially useful for obsolete original devices where factory support is no longer available. However, the EP1C3T144C8GA itself is marked Obsolete, so a migration plan should include one of the same-family orderable variants, a verified pinout from Intel, and configuration-bitstream extraction or re-synthesis from the original HDL netlist.

主要差異化特點
- Verified instock availability reported by multiple independent distributors as of 2026-09-06 (對比EP1C3T144C6N)
- Commercial 0 °C to 85 °C junction temperature range covers most indoor industrial and IoT environments (對比EP1C3T144I7)
- All EP1C3T144 same-family variants preserve the same 2910 LE, 59,904 RAM bit and 104 I/O resource set (對比EP1C3T144C7N)
設計說明
Estimated: provide a low-impedance VCCINT rail between 1.425 V and 1.575 V to the EP1C3T144C8GA. Place at least one 100 nF X7R ceramic capacitor beside each core supply pin and add bulk capacitance on the board to handle transient current during configuration. Use a single ground plane under the 144-LQFP package and keep the supply return paths short. Because no exact VCCINT current is listed in the verified web data, size the regulator after measuring actual core current on a prototype.
The Cyclone EP1C3 is an SRAM-based FPGA, so it does not retain its configuration when powered off. The EP1C3T144C8GA must be configured at every power-up from an external configuration device, FPGA configuration flash, or a host processor. Do not assume non-volatile behavior because no configuration memory type is stated in the verified web data. Also verify the exact ordering suffix and lead-free status with the supplier before using the GA part in a RoHS-controlled assembly line.
For a 144-pin LQFP with 104 user I/O, use a solid ground reference and treat high-speed I/O as transmission lines when edge rates are fast. Keep oscillator/configuration pins away from noisy switching outputs, and route the FPGA core voltage with a dedicated power plane or wide trace. Because the complete pinout is not reproduced in the verified web data, download the official Intel/Altera Cyclone pin table before finalizing the schematic and compare every one of the 144 pins with the target netlist.
合規資訊
Verified web data did not provide explicit RoHS, REACH, lead-free, halogen-free or conflict-minerals declarations for EP1C3T144C8GA. The GA suffix may imply a green/lead-free product, but it must be confirmed on the manufacturer datasheet or supplier certificate before assembly.
