EP1K100QC208-2 Présentation
An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device whose logic function is defined by a configuration bitstream loaded into on-chip SRAM. FPGAs sit at the top of the programmable-logic hierarchy, above CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple Programmable Logic Devices). The ACEX-1K family is positioned between low-density CPLDs and high-density FPGAs such as Stratix and Cyclone, making it suitable for mid-range glue logic, bus bridging, and DSP pre-processing tasks.
The EP1K100QC208-2 features 624 Logic Array Blocks (LABs), each containing 8 Logic Elements (LEs), giving the device a total of 4,992 LEs for combinational and sequential logic implementation. The embedded array provides efficient memory blocks for FIFO, dual-port RAM, and ROM functions without consuming external logic resources. The 147 user I/O pins are distributed across four I/O banks, each supporting 2.5 V LVTTL/LVCMOS signalling by default and configurable through the Quartus design tool.
Typical applications include telecommunications line-card interfaces, industrial control and instrumentation, low-cost glue logic replacement, legacy system prototyping, and education. The PQFP-208 footprint and the mature 2.5 V core also make the part suitable for designs where drop-in compatibility with existing ACEX-1K boards is required.
When designing with this device, engineers should note the PQFP-208 package requires careful PCB layout with respect to lead inductance and signal integrity, especially for clock and high-speed I/O nets. The 2.5 V core supply must be tightly regulated, and unused I/O pins should be configured as tri-stated inputs with weak pull-ups to reduce quiescent current.
This page synthesises distributor pricing, drop-in ACEX-1K alternatives in the same PQFP-208 footprint, and practical design notes that are not aggregated on a single manufacturer datasheet page.

Applications typiques
EP1K100QC208-2 convient pour 6 applications: Telecommunications Line-Card Interface, Industrial Control and Instrumentation, Legacy System Maintenance and Field Replacement, Educational and Prototyping Platforms, Glue Logic Replacement and Bus Bridging, Low-Cost DSP Pre-Processing Front-End.
Telecommunications Line-Card Interface
The EP1K100QC208-2 fits telecom line-card interface designs where 4,992 logic elements, 49,152 embedded bits, and 147 user I/O pins provide glue logic, framing, and protocol conversion between TDM buses and packet backplanes. At 250 MHz internal clock and 2.5 V core, the device supports standard LVCMOS-2.5 and LVTTL I/O on each interface. The 49 kbit embedded array dual-port memory implements small FIFO buffers for inter-rate conversion without external SRAM, reducing BOM cost. ACEX-1K mid-range density positions the part between CPLDs and high-end FPGAs for cost-sensitive line cards.
Recommandé
Industrial Control and Instrumentation
In industrial PLCs, motion controllers, and instrumentation front-ends, the EP1K100QC208-2 supplies the deterministic glue logic and custom DSP datapath that sits between analog front-ends and microcontrollers. The 147 I/O pins drive parallel ADC/DAC buses, encoder interfaces, and isolated digital I/O banks without external bus drivers. Embedded array blocks implement lookup tables for linearisation and calibration coefficients, freeing LEs for control algorithms. The 2.5 V core tolerates 2.375 V to 2.625 V supply variation typical of industrial 24 V-rail derived LDOs.
Recommandé
Legacy System Maintenance and Field Replacement
Designers maintaining installed industrial, military, or test equipment based on ACEX-1K boards use the EP1K100QC208-2 as a direct board-level replacement. The PQFP-208 footprint matches the original ACEX-1K PCB land pattern, and the existing Quartus II bitstream can be re-targeted without revalidation. Embedded array configurations remain bitstream-compatible across the family, so firmware can be re-flashed in place. The part is also useful for repairing boards where the original FPGA has failed due to EOS or end-of-life wear-out.
Recommandé
Educational and Prototyping Platforms
Universities and FPGA training labs use EP1K100QC208-2 boards as teaching vehicles because the part's modest logic density (4,992 LEs) keeps Quartus synthesis time short and student bitstreams small. The 147 I/O pins expose enough peripheral buses to drive LED arrays, character LCDs, and parallel ADCs without complex pin multiplexing. The 2.5 V core is generated cheaply from a USB 5 V rail via a single LDO, simplifying lab power design. The mature Quartus II toolchain and abundant example designs lower the barrier to first-time FPGA adoption.
Recommandé
Glue Logic Replacement and Bus Bridging
Designers replacing legacy discrete TTL/CMOS glue logic with a single programmable device use the EP1K100QC208-2 to consolidate address decoding, interrupt steering, and bus arbitration across mixed-width buses. The 147 I/O pins support multiple parallel interfaces simultaneously, while the 624 LABs implement deep state machines and address-mapped peripherals. Embedded array blocks provide FIFO buffers for crossing clock domains between asynchronous bus segments. The PQFP-208 footprint and 2.5 V core match legacy 2.5 V supply rails common in telecom backplane designs.
Recommandé
Low-Cost DSP Pre-Processing Front-End
In audio, vibration, and motor-control front-ends, the EP1K100QC208-2 pre-processes samples before handing data to a host DSP or microcontroller. The device implements FIR filters, FFT windows, and decimation chains in dedicated logic, offloading the host CPU. Embedded array dual-port memory holds coefficient tables and overlap buffers for sliding-window algorithms. At 250 MHz internal clock, the part comfortably sustains real-time audio bandwidth at 48 kS/s across multiple channels. The 147 I/O pins route multiple parallel ADC data streams into the device.

Principaux différenciateurs
- Drop-in compatible with all PQFP-208 ACEX-1K variants (vs EP1K100FC256-2)
- Higher density than ACEX-1K 50 and 30 family parts (vs EP1K50QC208-2)
- Mature Quartus II toolchain support with abundant example designs (vs Cyclone EP1C6Q240C8N)
Notes de conception
The EP1K100QC208-2 requires a tightly regulated 2.5 V core supply (VCCINT) with the allowable range of 2.375 V to 2.625 V and an I/O bank supply (VCCIO) per bank. Use a low-dropout regulator with at least 500 mA capability and 2.5 percent tolerance to keep VCCINT within spec. Decouple each VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible, supplemented by bulk tantalum or polymer capacitors on each supply rail.
The PQFP-208 package has gull-wing leads on a 0.5 mm pitch with a package body size of approximately 28 mm x 28 mm. Maintain a minimum of 8 mil trace width and 8 mil trace spacing inside the lead footprint to escape-route 147 user I/O pins. Place a continuous ground plane on the layer immediately beneath the device to provide a low-impedance return path for high-speed I/O. Keep clock traces short and impedance-controlled to 50 ohms to avoid reflections at 250 MHz.
Do not apply power to VCCINT before the I/O banks are powered; the ACEX-1K family datasheet requires a specific power-on sequence to avoid latch-up. Configure unused I/O pins as tri-stated inputs with weak pull-ups via the Quartus pin assignment tool to minimise quiescent current and reduce noise injection. When migrating from the -1 to the -2 speed grade, re-run Quartus timing analysis because timing models differ even though the pinout is identical.
Informations de conformité
RoHS compliance for the non-N variant is [DATA_NEEDED] in the verified distributor data; the -N lead-free variant is generally accepted as RoHS compliant. AEC-Q100 is not applicable because the ACEX-1K family is not automotive-qualified. Conflict-mineral compliance status is not stated in the provided web data.
