EP1K100FC256-1 概要
An FPGA (Field Programmable Gate Array) is a programmable logic device that integrates configurable logic blocks (CLBs), embedded memory, and programmable interconnects into a single silicon die. FPGAs sit in the digital semiconductor hierarchy as: programmable logic -> logic IC -> integrated circuit. The ACEX 1K family was Altera's first device to combine a lookup-table (LUT)-based logic array with embedded dual-port SRAM on a 2.5 V core, enabling System-On-a-Programmable-Chip (SOPC) integration for low-cost glue logic, bus interfaces, and DSP datapaths.
Key features of the EP1K100FC256-1 include 49,152 bits of true dual-port RAM organized into embedded array blocks (EABs), 4,992 logic elements for sequential and combinatorial logic, support for multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL, in-system programmability via the IEEE 1149.1 JTAG interface, and dedicated clock management with up to six clock pins and two dedicated clock networks. The device operates from a 2.5 V core supply with separate VCCIO banks for mixed-voltage interfacing.
Architecturally, the EP1K100FC256-1 uses an enhanced embedded array in which each EAB provides 4 Kbits of dual-port memory configurable as RAM, ROM, or multiplier, while the logic array provides fast interconnect between LABs (Logic Array Blocks). This hybrid LUT/embedded-memory architecture was tuned for high-throughput datapath designs in telecom, industrial control, and glue-logic applications during the early-2000s ACEX design cycle.
Typical applications include telecommunications line cards, industrial control and factory automation, PCI bridge and bus-interface glue logic, DSP co-processing front-ends, and legacy embedded system designs. The 256-pin FineLine BGA package supports dense board layouts with controlled-impedance signal routing required for 66 MHz PCI and 133 MHz SDRAM interfaces.
When designing with this part, validate timing closure against the Quartus II MAX+PLUS II timing models and confirm VCCIO bank voltages against the I/O standard selected; LVTTL outputs typically need 3.3 V VCCIO while SSTL memory interfaces require 2.5 V VCCIO. Programming is performed via JTAG using a ByteBlasterMV or MasterBlaster cable, with configuration data stored in an external serial EEPROM.

主な用途
EP1K100FC256-1 の用途: 6 件s: Telecommunications Line Card Glue Logic, PCI Bus Bridge and Interface Controller, Industrial Control and Factory Automation, DSP Co-Processing Front-End, Legacy Embedded System Design Migration, Test and Measurement Instrumentation.
Telecommunications Line Card Glue Logic
The EP1K100FC256-1 fits telecom line-card glue-logic applications because of its 100K-gate logic capacity, 186 user I/O pins, and 333.33 MHz maximum internal frequency - enough to bridge TDM buses, framers, and network processors in legacy DSLAM and SDH equipment. The 4,992 logic elements handle parallel datapath glue while the 49,152 bits of embedded dual-port RAM implement FIFO buffers for cell/packet queuing without external SRAM. Operating from a 2.5 V core with separate VCCIO banks, the device directly interfaces 3.3 V LVTTL and 2.5 V SSTL memory buses common in telecom backplanes. Engineers value its in-system JTAG programmability for field firmware updates without removing the line card from service.
おすすめ
PCI Bus Bridge and Interface Controller
With 4,992 logic elements and 186 I/O, the EP1K100FC256-1 is well matched to 33/66 MHz PCI bridge designs that require custom protocol translation or bus isolation between a host CPU and legacy peripherals. Its embedded dual-port EAB memory provides the bus-master FIFOs and DMA descriptor rings without needing external SRAM, reducing PCB area. The device's 3.3 V VCCIO bank capability drives PCI signals directly to the bus, while the 2.5 V core keeps power dissipation manageable in always-on systems. Quartus II MAX+PLUS II synthesis libraries include pre-built PCI megafunctions that drop in to the ACEX 1K logic array, dramatically reducing development time for PCI-target and PCI-master designs.
おすすめ
Industrial Control and Factory Automation
The EP1K100FC256-1 is suitable for industrial PLC, motor-control, and factory-automation controllers because of its 100K-gate density, JTAG field reprogrammability, and 186 I/O count for connecting to multi-axis servo drivers and digital I/O modules. The dual-port EABs implement deterministic inter-task message queues required for hard-real-time control loops. Although the commercial temperature grade limits it to 0C-70C operation, many factory-floor enclosures regulate internal ambient and accept commercial-grade silicon. Engineers should note the obsolete lifecycle status and qualify the EP1C20F400C6 (Cyclone) as a functional migration target for new industrial platforms as of 2026-09-06.
おすすめ
DSP Co-Processing Front-End
In DSP co-processing front-ends, the EP1K100FC256-1 acts as a pre-processor that performs FIR filtering, FFT windowing, or data-rate conversion before handing samples to a dedicated DSP. The embedded dual-port RAM blocks implement coefficient storage and circular sample buffers in a single device, eliminating external SRAM access latency. At 333.33 MHz internal frequency, the ACEX 1K can sustain 80-100 MHz FIR datapaths for moderate-order filters used in audio and baseband processing. The 256-BGA FineLine package provides controlled-impedance signal routing required for high-speed data converters and parallel ADC interfaces. Migrating to a Cyclone device is straightforward because the Quartus II toolchain is shared.
おすすめ
Legacy Embedded System Design Migration
Designers maintaining legacy products built around ACEX 1K FPGAs use the EP1K100FC256-1 as a direct lifecycle extension while planning migration to Cyclone-class devices. The 100K-gate density matches many legacy designs exactly, allowing identical Verilog/VHDL source to retarget with minimal changes. Because the part remains in distributor stock through obsolete-component brokers, field-replacement and warranty-service builds can continue without immediate board redesign. The -N suffix variant (EP1K100FC256-1N) provides RoHS-compliant assembly for production in regions requiring lead-free soldering. Engineers should track remaining channel inventory closely as availability has tightened through 2025-2026.
おすすめ
Test and Measurement Instrumentation
Test-and-measurement equipment such as logic analyzers, protocol analyzers, and bench-top data-acquisition systems used the EP1K100FC256-1 for trigger-pattern matching, timing-stamp generation, and parallel-bus capture because of its high I/O count and dual-port memory FIFO capability. The 186 user I/O pins support 16-32 channel digital sampling with minimal external multiplexing. Dual-port EABs implement 4 Kbit x N deep capture buffers without external SRAM. JTAG-based in-system programming simplifies manufacturing calibration and field firmware upgrades. For new T&M designs the EP1AGX50CF484C6N (Arria GX) provides integrated transceivers, but it is not a drop-in upgrade - PCB redesign is required.

設計ノート
Estimated: the EP1K100FC256-1 is in obsolete/EOL status as of 2026-09-06, and remaining channel inventory is concentrated at specialty brokers. Do not commit to new production designs without securing a multi-year supply agreement or qualifying the Cyclone EP1C20F400C6 as a functional migration target. Validate timing closure against the Quartus II MAX+PLUS II ACEX 1K timing models because the -1 speed grade is the slowest of the family and may fail timing at high Fmax targets.
The 256-ball FineLine BGA requires careful PCB stackup design: use a 4-6 layer board with continuous ground planes beneath the BGA and matched-impedance traces for high-speed signals. VCCINT and VCCIO decoupling capacitors must be placed within 100 mils of the respective supply balls, with a mix of 0.1 µF ceramic and 10 µF bulk capacitors to handle the simultaneous-switching-current transients typical of 186 I/O toggling. Reference the ACEX 1K datasheet pinout table for ball-grid coordinates.
Estimated: with 186 I/O at 3.3 V LVTTL driving 50 pF loads at 50 MHz, the EP1K100FC256-1 VCCIO current peaks near 1.5 A per bank; the 2.5 V VCCINT core draws approximately 200-400 mA depending on toggle rate and logic utilization. Total board power budget should reserve 4-5 W for the FPGA plus margin. Use a star-ground topology with the FPGA as the central component, and decouple each VCCIO bank independently to prevent switching noise from corrupting the JTAG configuration interface.
コンプライアンス情報
Standard EP1K100FC256-1 uses SnPb solder balls (non-RoHS). The EP1K100FC256-1N variant is the RoHS-compliant lead-free version. AEC-Q100 not applicable - this is a commercial-grade FPGA in the ACEX 1K family. Reach and conflict-mineral status not explicitly stated in datasheet; engineers should request a compliance letter from the broker when sourcing for European production.
