EP1K50FI256-2N 概要
An FPGA (Field Programmable Gate Array) is a semiconductor device built from an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and embedded memory blocks (EABs/BRAMs) that the designer can program after manufacture. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) -> FPGAs -> parallel/serial programmable accelerators. ACEX-1K specifically pairs look-up-table (LUT)-based logic with Embedded Array Blocks (EABs), allowing each EAB to implement RAM, ROM, dual-port RAM, or FIFO without consuming general LUT resources.
Key differentiating features include the EAB-based memory architecture (dual-port RAM and FIFO at up to 40,960 bits), the 360 LABs delivering 2,880 logic elements (10 LEs per LAB), and SameFrame pin-out migration across the 256-pin FineLine BGA family. The die operates from a 2.5 V core supply with separate VCCIO bank voltages, supporting mixed-voltage I/O (LVTTL, LVCMOS, PCI, SSTL). Per the ACEX-1K datasheet family, the device is built on a 0.22 µm SRAM-based process and supports in-system programmability via the IEEE 1149.1 JTAG interface and the Altera EPC configuration devices.
Architecturally, each LAB contains 10 LEs, each LE holding a 4-input LUT, a programmable register, a carry chain for arithmetic, and a register chain. The EABs are 4 Kbit blocks (40,960 total / 4 Kbit = 10 EABs typical for this density) usable as single- or dual-port RAM, ROM, or FIFO. The device uses SRAM configuration cells, so it must be configured at every power-up from a serial or parallel configuration PROM.
Typical applications include glue logic replacement, interface bridging (PCI to local bus, UART expansion), digital signal processing front-ends, prototype ASIC validation, and industrial control boards where moderate logic density and embedded memory are needed without the cost of high-density FPGAs.
When designing with this device, ensure the configuration scheme (PS, AS, JTAG) matches the chosen EPC configuration PROM. The 256-ball FineLine BGA is a SameFrame package - designs targeting the EP1K50 family can migrate to EP1K30 (smaller) or EP1K100 (larger) parts with no PCB rework. Watch thermal dissipation: even at modest toggle rates the 0.22 µm process can dissipate 1-2 W in still air; use a minimum 4-layer PCB with an internal ground plane.
This page synthesizes distributor pricing, drop-in alternatives within the ACEX-1K family, and SameFrame PCB-layout guidance not found in the bare datasheet, making it a single source for sourcing, replacement, and design-in decisions.

主な用途
EP1K50FI256-2N の用途: 6 件s: Glue Logic Replacement and Bus Bridging, Industrial Control and Factory Automation, Digital Signal Processing Front-End, ASIC Prototyping and Design Validation, Legacy Communication Interface Bridging, Test and Measurement Instrumentation Front-End.
Glue Logic Replacement and Bus Bridging
The EP1K50FI256-2N is well suited to replace discrete 74-series glue logic on legacy industrial boards, consolidating address decoding, chip-select generation, and bus arbitration into a single programmable device. Its 2,880 logic elements, 360 LABs, and 186 I/O pins provide ample capacity for multi-bridge designs (e.g., PCI to local bus, ISA to memory-mapped I/O), while the 2.5 V core with separate VCCIO banks allows direct interfacing to 3.3 V and 5 V peripherals. Compared to a CPLD-only solution, the EP1K50 adds EAB-based dual-port RAM (40,960 bits) for small FIFO buffers, eliminating an external SRAM chip. Place the device on a 4-layer PCB with an unbroken ground plane and use the Altera EPC configuration PROM for PS-mode boot to minimize board area.
おすすめ
Industrial Control and Factory Automation
In industrial control cabinets, the EP1K50FI256-2N handles encoder decoding, PWM generation, stepper/digital I/O scanning, and Modbus/Profibus protocol bridging. The 2.5 V core and LVTTL/LVCMOS-compatible I/O support direct connection to 24 V opto-isolated inputs through external level shifters, while 186 user I/O pins provide generous fan-out for multi-axis motion control. The 0.22 µm process and industrial temperature range make the part a robust workhorse for PLC backplanes. Compared to MCU-only solutions, the FPGA's parallel logic execution eliminates instruction-cycle jitter for deterministic control loops. For higher-density industrial designs, migrate to the EP1K100 or to a Cyclone IV/EP4CE part while preserving the 256-FBGA SameFrame footprint.
おすすめ
Digital Signal Processing Front-End
The EP1K50FI256-2N's EAB-based memory and 200 MHz internal frequency make it a practical DSP front-end for FIR filters, FFT pre-processors, and image-processing pipelines at moderate sample rates. Each EAB can implement a 4-Kbit ROM coefficient table or dual-port RAM data buffer, allowing the 40,960 total RAM bits to be split between data and coefficient memory without consuming general LUT resources. The 2,880 LEs provide enough logic for a 16-tap FIR or an 8-point radix-2 FFT at video-line rates. Use the Quartus II or MAX+PLUS II Megafunction Library for DSP cores; for new designs, migrate to Cyclone IV EP4CE6 or later for native DSP blocks and lower power.
おすすめ
ASIC Prototyping and Design Validation
Engineers use the EP1K50FI256-2N as an ASIC prototyping vehicle for mid-complexity ASIC designs (50K-200K gates), taking advantage of its in-system SRAM programmability to iterate RTL quickly without fabrication cost. The 186 I/O pins provide ample off-chip connectivity for emulating ASIC pin-outs, while JTAG-based reconfiguration supports fast design spins. The SameFrame 256-FBGA package allows design teams to swap EP1K30 (smaller), EP1K50 (this part), and EP1K100 (larger) on the same PCB during validation. Compared to ASIC fabrication, ACEX-1K offers a turnaround time measured in minutes. For modern prototyping, migrate to a Cyclone IV or Cyclone V dev kit.
おすすめ
Legacy Communication Interface Bridging
The EP1K50FI256-2N excels at bridging legacy telecom and datacom interfaces (UART, SPI, I2C, parallel bus, HDLC) to modern processors or backplanes. Its 2,880 LEs and EAB RAM allow multi-channel UART engines, HDLC framer/deframer blocks, and DMA controllers to coexist on a single chip. The 200 MHz internal frequency comfortably supports multi-megabaud serial streams, and the 256-FBGA package fits 1U line-card designs with high I/O fan-out. Compared to ASSP bridges, the FPGA allows field-upgradable protocol stacks. For new designs, Intel recommends migrating to Cyclone IV EP4CE6 or EP4CE10 for active lifecycle support and lower power.
おすすめ
Test and Measurement Instrumentation Front-End
In bench-top test equipment (logic analyzers, protocol exercisers, custom digitizers), the EP1K50FI256-2N provides trigger logic, pattern generation, and time-stamping at low cost. The 40,960 bits of EAB RAM allow sample buffers and lookup-table-based waveform synthesis, while the 186 I/O pins can directly drive LVTTL probe pods. The 200 MHz internal clock supports up to 100 MHz external sample rates in pipelined designs. Compared to dedicated test-ASICs, the FPGA offers reconfigurable test sequences in the field. For higher-speed or higher-density test gear, migrate to Cyclone IV or Cyclone V with transceivers, but preserve the 256-FBGA SameFrame mechanical outline if a mechanical retrofit is desired.

- EAB-based embedded memory architecture （vs EP1K100FI256-2N)

- Mid-density 50K-gate sweet spot （vs EP1K100FI256-2N)
設計ノート
Estimated: the EP1K50FI256-2N core draws approximately 100-300 mA from the 2.5 V rail at full toggle activity, with additional VCCIO bank current proportional to I/O switching. Total power dissipation in a typical 50% toggle-rate design is roughly 1-2 W. Use a low-ESR 100 µF bulk capacitor plus 0.1 µF and 0.01 µF ceramic decoupling on each VCC pin. Per the ACEX-1K datasheet, VCCIO must be ramped before or simultaneously with VCCINT; reverse sequencing can trigger high inrush current through the I/O cells. Place a power-OK reset supervisor to hold nCONFIG low until both rails are stable.
Use a 4-layer PCB with a continuous internal ground plane directly beneath the 256-FBGA footprint. The 1.0 mm ball pitch requires laser-drilled microvias or via-in-pad for signal escape; the Altera ACEX-1K hardware reference manual recommends 0.2 mm (8 mil) trace width and 0.2 mm via diameter. Provide at least 8 thermal vias in a 3x3 array under the die-shadow region of the package to conduct heat from the BGA balls to the internal ground plane. Match trace lengths within ±50 mil for clock and global signals; use series damping resistors on high-edge-rate outputs to reduce overshoot on the LVTTL/PCI I/O banks.
Common pitfalls: (1) the EP1K50FI256-2N is SRAM-based, so it loses configuration on power-down - always pair it with an Altera EPC1, EPC2, or EPC16 configuration PROM in PS or JTAG mode; (2) the 256-FBGA FineLine BGA is a SameFrame package shared with the EP1K30 and EP1K100, but the unused I/O pins differ - always refer to the ACEX-1K SameFrame pinout table when migrating densities; (3) MSL3 moisture sensitivity requires pre-bake and reflow profile per J-STD-020 to avoid package cracking; (4) counterfeit parts are common in the secondary market - verify lot/date code against the Altera/Intel traceability database before high-volume production use.
コンプライアンス情報
The 'N' suffix on EP1K50FI256-2N historically indicates a lead-free terminal finish, but full RoHS/REACH compliance status is not available in the verified web data and should be confirmed against the lot-specific CoC. AEC-Q100 is not applicable for FPGAs - the part is not automotive-qualified.
