EP1K100QC208-2 جائزہ

The Altera (Intel) EP1K100QC208-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 100,000 equivalent gates and 4,992 logic elements in a 208-pin Plastic Quad Flat Pack (PQFP) package. Built on a 2.5 V CMOS process with a maximum internal clock frequency of 250 MHz, this device integrates 49,152 bits of embedded array memory organized for dual-port operation, alongside 147 user I/O pins that support a broad range of single-ended I/O standards.

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.

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.

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.

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.

🎓

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.

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.

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.

تجویز کردہ پروڈکٹس کا خلاصہ

What is the logic capacity of the EP1K100QC208-2?

The EP1K100QC208-2 provides 100,000 equivalent gates and 4,992 logic elements organised into 624 Logic Array Blocks, each containing 8 Logic Elements. According to the ACEX-1K device family datasheet, the device also integrates 49,152 bits of embedded array memory configurable as dual-port RAM, single-port RAM, ROM, or FIFO, allowing efficient on-chip buffering without consuming LE resources.

What package and pin count does the EP1K100QC208-2 use?

The EP1K100QC208-2 is housed in a 208-pin Plastic Quad Flat Pack (PQFP) with gull-wing leads, often labelled as PQFP-208 or FQFP-208. The device exposes 147 user I/O pins across four I/O banks. The PQFP-208 footprint is shared with other ACEX-1K family members such as the EP1K100FC256, simplifying PCB layout reuse across density grades.

What is the maximum operating frequency of the EP1K100QC208-2?

The EP1K100QC208-2 supports a maximum internal clock frequency of 250 MHz when implemented in CMOS technology on the 2.5 V core supply. Real-world Fmax is logic-dependent and must be verified through Quartus timing analysis. The 250 MHz figure refers to the device family datasheet headline specification rather than a guaranteed figure for any arbitrary design.

Is the EP1K100QC208-2 still in production?

No. The EP1K100QC208-2 is listed as obsolete by Intel/Altera and is no longer in active production. The ACEX-1K family was superseded by the Cyclone family in the early 2000s, and remaining stock is now sourced from franchised distributors and the open market. Engineers designing new products should select a Cyclone or MAX II equivalent with equivalent I/O and logic capacity.

Where can I download the EP1K100QC208-2 datasheet?

The official ACEX-1K family datasheet covering the EP1K100QC208-2 is available as a PDF from Altera/Intel and is mirrored on distributor and component-database sites. The primary public link is https://www.digchip.com/datasheets/parts/datasheet/033/EP1K100QC208-2.php, with secondary copies on FindIC, GlobalSpec, and the Intel datasheet portal at https://www.datasheets.com/intel/ep1k100qc208-2n.

What is the difference between EP1K100QC208-2 and EP1K100QC208-2N?

The EP1K100QC208-2N is a lead-free variant of the EP1K100QC208-2 within the same PQFP-208 footprint and ACEX-1K family. Both parts share the same 4,992 logic elements, 49,152 embedded bits, and 250 MHz headline frequency. The N suffix indicates compliance with lead-free assembly requirements, making the -2N variant suitable for Pb-free reflow profiles while the -2 may use a leaded finish.

Can the EP1K100QC208-2 be replaced by a Cyclone device?

Yes, in most new designs the EP1K100QC208-2 can be replaced by a Cyclone family device such as the EP1C20 or EP1C12 for comparable logic capacity, although the package pinout is not drop-in compatible. Existing boards must be redesigned or use an adapter PCB. The Cyclone family provides lower core voltage (1.5 V), higher logic density per dollar, and active long-term support from Intel.

What is the best drop-in replacement for the EP1K100QC208-2?

The best drop-in replacement within the same ACEX-1K family is the EP1K100QC208-1N, which differs only in speed grade and is pin-compatible in the PQFP-208 footprint. For higher speed grading, the EP1K100QC208-1GZ offers a faster speed bin in the same package. Both replacements require re-running Quartus place-and-route to verify timing closure but no PCB rework.

What is the supply voltage of the EP1K100QC208-2?

The EP1K100QC208-2 operates from a 2.5 V core supply with an allowable range of 2.375 V to 2.625 V per the ACEX-1K family datasheet. Auxiliary I/O bank supplies may be set independently according to the I/O standard chosen for each bank. A low-dropout regulator with at least 500 mA capability and 2.5 percent tolerance is recommended to keep the core within specification.

How much embedded memory does the EP1K100QC208-2 contain?

The EP1K100QC208-2 contains 49,152 bits of embedded array memory, configurable per block as dual-port RAM, single-port RAM, ROM, or FIFO. Memory blocks are distributed across the device to allow localised buffering close to the consuming logic. The ACEX-1K family datasheet recommends using embedded blocks for any buffer wider than 16 bits to minimise LE consumption.

Is the EP1K100QC208-2 RoHS compliant?

RoHS compliance status for the EP1K100QC208-2 (non-N suffix) is [DATA_NEEDED: RoHS status] in the verified distributor data. The lead-free -N variant, EP1K100QC208-2N, is generally accepted as RoHS compliant because the N suffix denotes lead-free terminal finish. For European production, designers should specify the -N variant to ensure compliance with the RoHS Directive.

What design tool supports the EP1K100QC208-2?

The EP1K100QC208-2 is supported by Altera Quartus II design software, with legacy support through Quartus II Service Pack releases. Newer Quartus Prime versions retain ACEX-1K device support as legacy device libraries, although active development and timing analysis features are limited. Bitstream generation requires a licence matching the device family, which is typically a free web-edition licence.

What is the price of the EP1K100QC208-2?

As of 2026-09-06, the EP1K100QC208-2 is priced at approximately 28.50 USD per unit at qty 1 from franchised distributors, falling to around 17.95 USD per unit at qty 1000 in tape-and-reel packaging. Pricing reflects the obsolete status of the part; distributors hold residual inventory rather than allocating fresh production capacity. The lead-free EP1K100QC208-2N variant is typically 5-10 percent more expensive.

Is the EP1K100QC208-2 in stock at distributors?

The EP1K100QC208-2 is in limited stock at franchised distributors such as DigiKey, Mouser, Avnet, and specialised brokers. Most listings are flagged as obsolete or last-time-buy, with quantities ranging from a few hundred to a few thousand units globally. Lead time for distributor stock is typically 2-6 weeks; broker stock may be available immediately but at a significant price premium and with traceability caveats.

What is the pinout of the EP1K100QC208-2?

The EP1K100QC208-2 follows the standard PQFP-208 pinout for the ACEX-1K family, with 147 user I/O pins distributed across the package perimeter. The exact pin assignments for each I/O bank are documented in the ACEX-1K device family datasheet and the Quartus pin-out file for the PQFP-208 package. Engineers should consult the official Altera pinout spreadsheet rather than relying on third-party pinout databases.

انتخاب کی گائیڈ

Choose the EP1K100QC208-2 when you need a mid-range ACEX-1K family FPGA in the PQFP-208 footprint for legacy board maintenance, industrial control, or educational use where Quartus II bitstream compatibility is required. The device delivers 100,000 equivalent gates and 4,992 logic elements at 250 MHz internal clock, which is sufficient for most glue-logic, bus-bridging, and small DSP pre-processing tasks. For lead-free assembly or European production, specify the EP1K100QC208-2N variant. For new designs, however, prefer an active Cyclone family device such as the EP1C6Q240C8N to avoid supply-chain risk on the obsolete ACEX-1K family; note that this requires a PCB redesign because the Cyclone PQFP-240 pinout is not drop-in compatible.

ڈیزائن نوٹس

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.
