EP1K10FC256-2N 概要
What is a FPGA? A Field-Programmable Gate Array is a semiconductor device based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> high-density SRAM-based FPGAs. Unlike fixed-function ASICs, FPGAs can be reconfigured in-system to implement custom digital logic, glue logic, signal processing pipelines, and bus interfaces, making them ideal for prototyping and low-to-mid volume production.
Key features of the EP1K10FC256-2N include 0.5 ns pin-to-pin logic delay, built-in dual-port RAM, support for the Altera MAX+PLUS II and Quartus design flows, and a 2.375 V to 2.625 V core supply. The 256-ball FineLine BGA package provides high I/O density for memory-rich and bus-interface designs, while the commercial 0 °C to 70 °C operating range suits bench instrumentation, communications glue logic, and industrial control boards.
The ACEX-1K architecture uses an embedded array of Enhanced Logic Elements (ELEs) interleaved with embedded array blocks (EABs) that implement dedicated dual-port RAM and ROM. This hybrid fabric lets designers place megafunctions such as FIFOs, CAMs, multipliers, and DSP blocks in silicon-efficient EABs while reserving LUTs for random logic, yielding better performance-per-area than pure 4-input LUT FPGAs of the same era.
Typical applications include glue logic for legacy microprocessor buses, peripheral controllers (UART, SPI, I2C bridges), low-speed digital signal processing front-ends, prototyping platforms, and industrial communication bridges. The 136 available user I/Os also make the EP1K10FC256-2N a practical fit for memory-interface bridging, where the 12 Kbits of embedded RAM act as a small cache or FIFO between two clock domains.
When designing with this device, plan power sequencing carefully because the 2.5 V core must ramp monotonically while I/O banks can be powered at 3.3 V to remain LVTTL/LVCMOS-compatible. Decoupling requires 0.1 µF high-frequency capacitors placed within 5 mm of every supply pin, plus bulk capacitance on each supply plane to manage in-rush during configuration.

主な用途
EP1K10FC256-2N の用途: 6 件s: Legacy Microprocessor Bus Glue Logic, Peripheral Controller / UART-SPI-I2C Bridge, Low-Speed Digital Signal Processing Front-End, Industrial Communication Bridge, Prototyping Platform for ASIC / SoC Designs, Memory Interface Bridge (FIFO / Clock-Domain Crossing).
Legacy Microprocessor Bus Glue Logic
The EP1K10FC256-2N is well suited for legacy microprocessor bus glue logic applications. Its 10,000-gate ACEX-1K fabric, 136 user I/Os, and 0.5 ns pin-to-pin delay enable fast address decoding, wait-state generation, and interrupt control between 8/16/32-bit CPUs and peripheral chips. Place the FPGA between the CPU bus and glue-less peripherals to reduce board area; the 2.5 V core plus 3.3 V-tolerant I/O banks interface cleanly to both 3.3 V microcontrollers and 5 V-tolerant peripherals via external resistors.
おすすめ
Peripheral Controller / UART-SPI-I2C Bridge
Bridge between UART, SPI, and I2C peripherals in embedded designs using the EP1K10FC256-2N. The 576 logic elements are sufficient to implement several soft IP cores simultaneously (8051 core, UART, SPI master/slave, I2C controller), while the 12 Kbits of dual-port RAM provide FIFO buffers between mismatched baud-rate domains. The 0.5 ns pin-to-pin delay keeps interrupt latency under 50 ns, making this FPGA a practical peripheral-expansion coprocessor for legacy MCUs.
おすすめ
Low-Speed Digital Signal Processing Front-End
Implement low-speed DSP front-ends in the EP1K10FC256-2N such as FIR filters, decimators, and simple FFT pre-processors for instrumentation and audio preprocessing. The 72 LABs with embedded multipliers (via EAB configuration) handle 8-bit audio sample rates up to 5 MSPS, while 136 user I/Os expose parallel ADC/DAC buses. Power dissipation stays under 250 mW at 50 MHz, suitable for portable or fan-less test instruments.
おすすめ
Industrial Communication Bridge
Use the EP1K10FC256-2N as a multi-protocol industrial bridge converting between RS-232, RS-485, CAN, and Modbus on factory floor equipment. The 136 user I/Os support 8 to 16 differential transceiver pairs, while the 12 Kbits RAM implements Modbus message buffers. Industrial temperature grade is NOT available on the -2N; for -40 °C to +85 °C operation choose EP1K10FI256-2N as a drop-in upgrade with identical silicon.
おすすめ
Prototyping Platform for ASIC / SoC Designs
Prototype ASIC and SoC designs in the EP1K10FC256-2N before committing to mask costs. ACEX-1K FPGAs were widely used for first-pass validation of bus interfaces, custom peripherals, and control logic in the early 2000s. Quartus II and MAX+PLUS II support full HDL synthesis (VHDL/Verilog), and the 256-BGA exposes enough I/Os to validate 32-bit buses plus JTAG and trace. Pair with a Cyclone IV or Cyclone V board for modern prototyping flows.
おすすめ
Memory Interface Bridge (FIFO / Clock-Domain Crossing)
Bridge asynchronous memory interfaces with the EP1K10FC256-2N. The 12 Kbits of embedded dual-port RAM implement 1.5 Kbyte FIFOs that absorb timing differences between two clock domains, while the 136 user I/Os expose parallel SRAM, SDRAM, and legacy DRAM control signals. ACEX-1K's dedicated EAB dual-port architecture provides deterministic two-port access at up to 133 MHz, ideal for camera frame buffers and communications payload assembly.

設計ノート
The EP1K10FC256-2N requires a 2.375 V to 2.625 V core supply (VCCINT) with monotonic ramp during configuration; an out-of-spec ramp can corrupt the SRAM configuration bitcells. Place a 0.1 µF X7R ceramic decoupling capacitor within 5 mm of every VCCINT ball and bulk-decouple each supply plane with a 10 µF tantalum. I/O banks (VCCIO) can be powered at 3.3 V to remain LVTTL/LVCMOS-compatible, but all banks must ramp within 100 ms of each other to avoid I/O contention.
The 256-ball FineLine BGA uses a 1.0 mm ball pitch with 17 mm × 17 mm body. Use at least 4-layer PCB with a continuous ground plane directly under the BGA to provide both thermal spreading and controlled-impedance reference for high-speed I/Os. Escape traces through the inner rows requires microvia (laser-drilled) or 0.4 mm-pitch dog-bone fan-out; standard 0.2 mm via-in-pad is recommended for the inner balls to maintain signal integrity above 100 MHz.
Estimated: The EP1K10FC256-2N draws approximately 30 mA quiescent VCCINT current and up to 250 mA during active configuration. Do NOT hot-swap or hot-plug this device because the SRAM configuration is volatile and the JTAG chain must be re-initialized after any power glitch. When migrating from EP1K10FC256-1 to -2N, re-run static timing analysis because the 0.5 ns pin-to-pin delay improvement shifts setup/hold margins by roughly 25 %; conversely, when migrating from -2N to -1, retiming may be required if the design operated near the speed limit.
