EP1K50QC208-1N Visão geral
An FPGA is an integrated circuit containing reprogrammable logic fabric that can implement arbitrary digital logic after manufacturing. Unlike fixed ASICs, an FPGA is field programmable, allowing designers to change pin functions, interfaces, and state machines by loading a configuration bitstream. In the device hierarchy, the ACEX 1K FPGA sits below complex SoCs and ASICs for flexibility and above CPLDs for density, making it suitable for data-path, DSP, control, and interface designs.
Key features include 2,880 logic elements organized into 360 LABs, 40,960 bits of on-chip memory, 147 user I/O pins, and 2.5 V core operation. The device is listed with a 250 MHz maximum operating frequency and is manufactured on a 0.22 um CMOS process. The FPGA uses LUT-based logic for efficient data-path implementation and embeds EABs that support RAM, ROM, dual-port RAM, and FIFO functions.
Architecturally, ACEX 1K combines a look-up table structure with embedded array blocks to deliver a die-efficient, low-cost programmable platform. The LUT fabric is particularly effective in register intensive and mathematical designs, while the EABs reduce external memory requirements by absorbing FIFOs and small RAM blocks. This makes the EP1K50QC208-1N a practical option for legacy 2.5 V systems needing moderate logic density and predictable timing.
Typical applications include communication line-card bridging, DSP co-processing, industrial control interfaces, video acquisition, and legacy bus integration. The 147 user I/Os allow the FPGA to connect directly to microcontrollers, backplane transceivers, DACs, ADCs, and memory buses, while the embedded memory holds coefficients or packet buffers. Designers can prototype in-system and reprogram without board changes.
When designing the EP1K50QC208-1N into a system, place capacitors close to the 2.5 V core supply pins and follow the ACEX 1K configuration guidelines. The FPGA must load its configuration from an external Altera configuration device such as EPC2, EPC1441, or through a JTAG download cable after power-up. Verify configuration source and power sequencing before committing the PCB layout.

Aplicações típicas
EP1K50QC208-1N é adequado para 6 aplicaçãos: Communication System Interface, DSP Co-Processing, Industrial Control Logic, Video and Image Acquisition, System Prototyping and Validation, Legacy Bus and Peripheral Bridging.
Communication System Interface
The EP1K50QC208-1N is useful in communication system line cards and interface boards because its 2,880 logic elements and 147 user I/O can implement packet classification, protocol conversion, or bus bridging without an expensive ASIC. The embedded 40,960 bits of RAM can be configured as FIFOs or dual-port RAM for buffering between a backplane and a PHY, reducing external memory count. The 2.5 V core lowers power in always-on communication equipment. In a typical design, the FPGA connects directly to a line transceiver and a host microcontroller, while an EPC2 configuration device loads the bitstream at power-up. A trade-off is that the FPGA itself is volatile and adds configuration delay after reset, so designers must account for startup time in the host software.
Recomendado
DSP Co-Processing
EP1K50QC208-1N can serve as a DSP co-processor in systems that need parallel arithmetic without dedicating a host processor. The ACEX 1K LUT architecture is well suited to finite impulse response filters, multipliers, adders, and correlators. With 2,880 logic elements, the FPGA can hold a small multiply-accumulate datapath, while the 40,960 bits of embedded RAM store coefficient tables or delay-line samples. The 147 I/O connect to ADCs, DACs, or a system bus. The reported 250 MHz performance class supports high-throughput control-loop and signal-conditioning tasks. The main design trade-off is that the FPGA consumes 2.5 V core power and must be configured before it can start computation, so a processor supervising configuration is recommended in mixed-signal systems.
Recomendado
Industrial Control Logic
Industrial automation panels often require flexible glue logic for motor controller interfaces, encoder counters, safety interlocks, and parallel I/O expansion. The EP1K50QC208-1N fits this role because it provides 147 reconfigurable I/O pins and sufficient logic elements to replace multiple 74-series devices in one package. Its embedded RAM can implement small state tables or FIFOs for communication with PLCs and sensors. The 2.5 V core supply is easily derived from a 3.3 V or 5 V industrial rail with a simple regulator. Because the QC suffix indicates a commercial temperature version, verify the product-specific temperature range in the datasheet for harsh environments; the QI industrial temperature variant is better suited when the panel must operate outside a controlled room temperature range.
Recomendado
Video and Image Acquisition
EP1K50QC208-1N can perform preprocessing in video and image acquisition systems by buffering pixel streams, generating synchronization pulses, and applying simple line-level algorithms. The FPGA's 40,960 bits of embedded RAM are enough for small line buffers or FIFO storage when transferring video data from a CMOS sensor to a DSP or application processor. Its 2,880 logic elements can implement timing generators, region-of-interest counters, and external memory controller glue. The 147 user I/O allow direct connection to parallel video buses at LVTTL-like voltage levels. A key trade-off is that full-frame high-definition image buffering would require external SDRAM, since the internal memory is limited. For standard-definition or low-resolution industrial cameras, however, the FPGA provides a low-cost reprogrammable acquisition front end.
Recomendado
System Prototyping and Validation
The EP1K50QC208-1N supports rapid prototyping of glue logic, state machines, and bus interfaces because it can be reprogrammed on the bench through a configuration download cable or an EPC2 device. A validation engineer can map a candidate 74-series logic design into the FPGA, verify pin assignments in the 208 PQFP footprint, and change the logic without cutting PCB traces. With 2880 logic elements and 147 I/O, it is large enough for a broad range of prototype functions yet still uses a standard QFP package that can be hand-prototyped. The 2.5 V core and N lead-free finish simplify modern PCB assembly. The main limitation is that the FPGA requires external configuration storage, so the prototype PCB must include a configuration header, configuration device, or host CPU download path.
Recomendado
Legacy Bus and Peripheral Bridging
EP1K50QC208-1N is a practical bridge between legacy parallel buses and newer system interfaces in industrial and telecom equipment. The 147 user I/O can connect directly to a legacy microcontroller bus, SRAM interface, or backplane. The FPGA can perform address decoding, wait-state generation, interrupt routing, and simple protocol conversion. Its 40,960 bits of embedded RAM can be used as packet FIFO or mailbox memory between two clock domains. The 2.5 V core supply must be generated from the legacy bus voltage, and level shifting may be required if the microcontroller uses 3.3 V or 5 V I/O. Because the device is from the ACEX 1K family, engineers can keep one PCB footprint and swap among EP1K50 speed grades if a -1N becomes difficult to source.

Notas de projeto
The EP1K50QC208-1N core supply is 2.5 V. Place low-ESR ceramic capacitors of 0.1 uF or 0.01 uF close to each FPGA supply pin and at least one 10 uF bulk capacitor near the power entry of the 208 PQFP device. The exact decoupling recommendations vary by design, but the 2.5 V plane should be continuous under the FPGA body. Because the device voltage is lower than legacy 5 V logic, confirm whether I/O buffers need external level translation for 5 V interfaces.
An ACEX 1K FPGA is volatile and must be configured after every power-up. If you omit the configuration source, the EP1K50QC208-1N pins remain tri-stated and the logic does not operate. Use an EPC2/EPC1441 configuration device, a download cable header, or a host processor with passive serial programming. Check nCONFIG, DCLK, DATA0, and nSTATUS signals in the ACEX 1K datasheet, and verify that the configuration clock and data polarity match the selected scheme.
The 208-pin PQFP has gull-wing leads and no central thermal pad. Ensure the copper pads are aligned with the IPC footprint and provide vias near the ground ring to connect the exposed board ground plane. A 208 QFP is mechanically larger than modern QFN devices, so allow adequate solder fillet inspectability around all four sides. The part has not had an exact thermal resistance value supplied in the verified data; estimate power dissipation only after reviewing the full ACEX 1K power section, and add copper area if the board will be used above room temperature.
Informações de conformidade
The N suffix in Altera part numbering indicates a lead-free/ROHS-compliant finish. Exact REACH, halogen-free, and conflict mineral statements were not included in the verified web data and require manufacturer confirmation.
