EP1K50QC208-3Q 개요
An FPGA (Field Programmable Gate Array) is a programmable logic device that contains an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells. ACEX 1K belongs to the embedded-array PLD category, which combines look-up-table (LUT)-based logic fabric with embedded memory blocks (EABs) for efficient implementation of megafunctions such as dual-port RAM, ROM, FIFO and DSP functions. Positioned in the broader taxonomy, ACEX 1K sits between classic CPLDs (lower density) and the higher-end APEX / Cyclone families (higher density) within Altera's programmable logic portfolio.
Key features include 360 Logic Array Blocks (LABs), 12 Embedded Array Blocks (EABs) totalling 40,960 bits of RAM, multi-volt I/O support (2.5 V / 3.3 V / 5.0 V tolerant), in-system programmability via IEEE 1149.1 JTAG, and built-in PCI compliance. The Look-Up Table (LUT) architecture delivers fast combinational logic, while the EABs provide up to 16 bits per block of dual-port RAM — a rare feature in this density class. The 208-pin PQFP package supports both commercial (0 °C to 70 °C) and industrial (-40 °C to 85 °C) operating ranges depending on suffix, with the -3Q suffix here indicating a ruggedized/military-grade temperature range.
The ACEX 1K architecture uses a continuous interconnect structure (DirectDrive) with predictable timing, four-input LUTs, and dedicated carry chains for arithmetic. Each EAB can be configured as 256×16, 512×8, 1024×4, 2048×2 or 4096×1 memory, or as a multiplier block. I/O banks are independently configurable to 2.5 V, 3.3 V or 5.0 V LVTTL/LVCMOS interfaces, allowing mixed-voltage system designs without external level shifters.
Typical applications include industrial glue logic and bus interface bridges, telecommunications line cards, military and avionics control systems, low-cost DSP preprocessing, glue logic for legacy 5 V/3.3 V systems, and PCI target devices. The 208-PQFP footprint also makes it suitable for through-hole-friendly assembly where BGA rework capability is limited. Compared to ASICs at this density, the ACEX 1K offers NRE-free prototyping and rapid design iteration through Quartus II design software.
When designing with the EP1K50QC208-3Q, observe multi-volt I/O bank constraints — each bank shares a VCCIO rail, so mixed-voltage peripherals must be grouped. Use the Quartus II Place-and-Route fitter reports to verify timing closure at 166.67 MHz, and ensure JTAG chain integrity before relying on in-system programming for production.

일반적인 애플리케이션
EP1K50QC208-3Q 적합 용도: 7 애플리케이션s: Legacy Military & Aerospace Control Systems, Telecommunications Line Cards, Industrial Glue Logic & Bus Interface Bridges, PCI Target Devices, Low-Cost DSP Preprocessing, Mixed-Voltage System Bridging, Legacy Through-Hole Replacement Platforms.
Legacy Military & Aerospace Control Systems
The EP1K50QC208-3Q's military-grade temperature suffix (Q) and ruggedized PQFP package make it a strong fit for defense and aerospace control systems where commercial-grade FPGAs fail qualification. The 208-PQFP footprint tolerates vibration and thermal-cycling environments better than fine-pitch BGAs, while the 50K-gate / 2,880-LE capacity is sufficient for avionics bus bridges, flight-control peripherals, and MIL-STD-1553 interface logic. JTAG in-system programming supports field updates without board removal, critical for deployed aerospace platforms.

Telecommunications Line Cards
In telecom line-card designs, the EP1K50QC208-3Q functions as a flexible glue-logic and packet-processing engine between network processors and PHY devices. The 12 EABs deliver 40,960 bits of dual-port RAM — enough for small FIFO buffers, lookup tables, and protocol-header parsing without external SRAM. Multi-volt I/O banks (2.5 V/3.3 V/5.0 V) bridge legacy 5 V backplanes to modern 3.3 V or 2.5 V framers, and PCI compliance enables direct attachment to PowerPC or MIPS host processors. The 166.67 MHz fabric supports 155 Mbps ATM/SDH traffic shaping.
추천
Industrial Glue Logic & Bus Interface Bridges
Industrial controllers often require custom bus-protocol bridges between legacy and modern peripherals — I2C-to-SPI, parallel-to-LVDS, or custom real-time fieldbus protocols. The EP1K50QC208-3Q delivers 50,000 gates of LUT-based logic with predictable DirectDrive timing, ideal for synthesizing state machines and protocol converters. The 147 user I/Os in the 208-PQFP package support wide parallel buses (16- or 32-bit) and the 5 V-tolerant I/O banks interface directly to legacy 5 V industrial peripherals without level shifters.
추천
PCI Target Devices
The ACEX 1K family is PCI-compliant out of the box, making the EP1K50QC208-3Q a drop-in solution for PCI add-in cards operating at 33 MHz / 32-bit. The 50K-gate capacity is well-matched to PCI target implementations with companion user logic (DMA controllers, custom peripherals, or legacy I/O bridges). Five-volt-tolerant I/O banks support both 5 V and 3.3 V PCI signaling, and the 208-PQFP package provides sufficient I/Os for the 49-pin PCI bus plus side-band signals. Designers can use Altera's PCI megafunction to reduce development time.

Low-Cost DSP Preprocessing
For DSP preprocessing tasks — digital filtering, FFT preprocessing, FIR/IIR pipelines, or sample-rate conversion — the EP1K50QC208-3Q's 12 EABs (40,960 bits) can be configured as coefficient ROMs and delay-line RAM, while the LUT fabric implements arithmetic. The 166.67 MHz fabric enables real-time processing of audio-band signals (≤50 MHz) and baseband communications. The 208-PQFP package supports standard reflow soldering and is far cheaper to assemble than BGA alternatives, making the EP1K50QC208-3Q attractive for cost-sensitive DSP front-ends.
추천
Mixed-Voltage System Bridging
When a design must interface 5 V legacy peripherals with 3.3 V or 2.5 V modern ASICs, the EP1K50QC208-3Q's independently configurable VCCIO banks provide a single-chip bridging solution. Each of the four I/O banks can be set to 2.5 V, 3.3 V, or 5.0 V, allowing direct voltage translation without external level-shifters. The 147 user I/Os are partitioned across these banks so designers can group peripherals by voltage domain. This is particularly valuable in industrial upgrades where 5 V sensors must coexist with newer 3.3 V MCUs.
추천
Legacy Through-Hole Replacement Platforms
For designs where BGA assembly or rework is impractical — educational labs, prototyping environments, or field-replaceable industrial modules — the 208-PQFP package offers a robust through-hole-friendly footprint with 0.5 mm lead pitch that is hand-solderable with care. The EP1K50QC208-3Q therefore remains a popular choice for university digital-logic labs, hobbyist retro-computing projects, and field-repair scenarios where fine-pitch BGA parts cannot be reworked. Designers can use the same Quartus II toolchain as production ACEX 1K BGA designs.

설계 노트
Place all four VCCINT (2.5 V core) decoupling capacitors within 2 mm of their respective pins, using 0.1 µF X7R ceramics in parallel with 10 µF tantalum or polymer bulk caps. Each VCCIO bank should have its own 0.1 µF + 10 µF decoupling network — mixing banks without dedicated decoupling causes voltage droop during simultaneous switching outputs (SSO). The 208-PQFP package's lead inductance (≈ 5 nH per pin) makes high-frequency decoupling critical above 100 MHz toggle rates.
When using 5 V VCCIO to interface legacy peripherals, verify that the 5 V input high-level voltage (VIH = 3.5 V min for 5 V LVTTL) is met under worst-case VCCIO tolerance. Outputs at 5 V VCCIO produce VOH = 3.8 V min — if the receiving device requires true 5 V CMOS VOH ≥ 4.5 V, an external pull-up to 5 V may be required. For 33 MHz PCI applications, source-terminate clock traces with 33 Ω series resistors to dampen reflections; PCI spec requires clock-to-PCI_CLK skew ≤ 2 ns.
Do not configure all four I/O banks to different voltages without checking the ACEX 1K datasheet's allowed bank-adjacency rules — some VCCIO combinations stress the I/O buffers' ESD structures. The JTAG chain (TCK/TMS/TDI/TDO) must include the 1 kΩ pull-up on TCK and 10 kΩ pull-up on TMS per IEEE 1149.1; missing pull-ups cause intermittent programming failures. When using the Quartus II 13.0 sp1 toolchain, always select the correct device variant (-3 vs -2 vs -1) before compilation — speed-grade mismatches produce silent timing failures that pass functional simulation but fail in hardware.
The 208-PQFP package has a 0.5 mm lead pitch; route signals on inner layers with 0.15 mm trace/space and use via-in-pad only on power/ground. For JTAG chain integrity, keep TCK trace under 100 mm total length and avoid parallel routing with high-speed clocks for at least 3× the trace spacing. If using the device's dual-port RAM at full 166.67 MHz, place EAB read/write address/clock traces on a dedicated inner layer with ground-plane shielding above and below.
