EP1K10QC208-3 개요
An FPGA (Field Programmable Gate Array) is a reconfigurable integrated circuit whose logic function is defined by a user-supplied configuration bitstream rather than by fixed factory mask wiring. FPGAs sit within the broader programmable logic hierarchy: PLD (Programmable Logic Device) -> CPLD (Complex PLD) -> FPGA. Compared with fixed-function ASICs, FPGAs trade raw performance-per-watt and unit cost for design flexibility, fast prototyping, and field-upgradability, making them the dominant platform for low-to-medium volume digital logic, glue logic, DSP pipelines, and I/O expansion.
Key features of the EP1K10QC208-3 include 120 user I/O pins, 72 LABs (Logic Array Blocks) organized in a dual-port Embedded Array Block (EAB) fabric, an internal core clock network supporting up to 200 MHz operation, and 6 dedicated clock inputs. The -3 speed grade places this part in the faster tier of the ACEX-1K family, and the 'QC' package suffix identifies the 208-pin PQFP variant. The device supports hot-socketing and multi-voltage I/O standards including LVTTL, LVCMOS, PCI, and SSTL.
The architecture is built around an Enhanced Embedded Array for implementing megafunctions such as efficient memory and specialized logic functions, with dual-port EABs that can be configured as RAM, ROM, or FIFO. Logic is implemented in a 4-input look-up table (LUT) per LE, with dedicated carry chains for arithmetic and a rich interconnect fabric (FastTrack) for predictable timing closure.
Typical applications include glue logic in industrial controllers, I/O expansion for microcontrollers, low-cost DSP preprocessing, custom peripheral interfacing, and legacy system upgrades where the original ACEX-1K design cannot be re-engineered. The PQFP-208 package is well suited to through-hole prototype boards and older manufacturing lines that cannot accept fine-pitch BGA packages.
When designing with this device, note that the ACEX-1K family is mature and has been classified NRND (Not Recommended for New Designs) by Intel/Altera; new designs should consider Cyclone or MAX II families. Configuration requires an external EPROM, EEPROM, or controller-based scheme and JTAG for in-system programming.

일반적인 애플리케이션
EP1K10QC208-3 적합 용도: 7 애플리케이션s: Industrial Glue Logic Replacement, Legacy Telecom Backplane Bridging, Test and Measurement Front-End Logic, Custom Peripheral Expansion for Embedded MCUs, Aerospace Avionics Bus Replication, Medical Imaging Pipeline Front-End, Education and FPGA Training Platforms.
Industrial Glue Logic Replacement
The EP1K10QC208-3 fits industrial glue logic replacement because its 576 LEs and 120 user I/Os match the typical size of legacy discrete 74HC/74F logic boards being modernized. Engineers retrofit the FPGA onto existing PQFP-208 footprints without redesigning the PCB, replacing dozens of SSI/MSI logic chips with a single reconfigurable device. The 2.5V core and 3.3V multi-standard I/O allow direct interfacing with TTL-era control signals. A typical application routes sensor conditioning outputs, stepper motor pulse trains, and encoder quadrature into the device and emits coordinated timing and direction signals to downstream drivers, achieving a 10:1 PCB area reduction and field-upgradable logic.

Legacy Telecom Backplane Bridging
The EP1K10QC208-3 is well suited to legacy telecom backplane bridging where older E1/T1 line interface cards need a modern protocol glue layer without board redesign. The 120 user I/Os map cleanly to typical 16-32 channel PCM/HDB3 framers, while the 12,288 bits of dual-port EAB RAM implement small elastic buffers and lookup tables. The PQFP-208 footprint preserves the original backplane keep-out zones. Combined with the -3 speed grade supporting up to 200 MHz, the device easily meets E1 (2.048 MHz) and T1 (1.544 MHz) timing margins with substantial headroom, making it ideal for sustaining equipment that is no longer factory-supported.
추천
Test and Measurement Front-End Logic
The EP1K10QC208-3 serves as front-end pattern generation and capture logic in test and measurement instruments where reconfigurable stimulus sequences are needed across product families. The 576 LEs accommodate a 16-bit pattern generator with one-hot decoders, while the 12 Kbit EAB RAM stores up to 1024 pattern vectors accessible in a single clock cycle. The 120 user I/Os fan out to multi-channel analog switches and comparators. The PQFP-208 package is preferred in T&M chassis that already have through-hole-compatible test sockets. Engineers can reconfigure the FPGA in seconds via JTAG to support a new DUT protocol, dramatically reducing test development cycle time.
추천
Custom Peripheral Expansion for Embedded MCUs
The EP1K10QC208-3 functions as a custom peripheral expansion layer between a microcontroller and high-pin-count external devices, offloading timing-sensitive or parallel I/O tasks from the MCU firmware. With 120 user I/Os and a 200 MHz internal clock, the device can implement multi-channel PWM, quadrature decoders, custom display drivers, or parallel data acquisition without taxing the host MCU. The PQFP-208 package is large enough for hand-soldered prototypes. The dual-port EAB RAM enables shared-memory communication with the host MCU, allowing zero-overhead data exchange. This pattern is common in industrial control retrofits where the existing MCU is fixed but additional I/O or timing logic must be added.
추천
Aerospace Avionics Bus Replication
The EP1K10QC208-3 is used to replicate MIL-STD-1553, ARINC 429, and other avionics bus traffic in legacy aircraft retrofit programs where the original bus controller ICs are obsolete. Its 120 user I/Os accommodate multiple bus channels simultaneously, while the 12 Kbit EAB RAM buffers message frames. The -3 speed grade provides timing margin for the 1 Mbps ARINC 429 data rate with substantial setup/hold slack. The PQFP-208 package tolerates the conformal coating and vibration profiles typical of avionics LRUs. This is a sustaining engineering application, not a new design, but the EP1K10QC208-3 is well matched to the bitstream-portability and PQFP footprint of the original ACEX-1K-based avionics designs.
추천
Medical Imaging Pipeline Front-End
The EP1K10QC208-3 acts as a low-cost pre-processing stage in legacy ultrasound or endoscopy imaging pipelines where pixel-level corrections (gain, offset, gamma) and simple spatial filters are required before the data is DMA-streamed to a host DSP. The 576 LEs handle 8-bit pixel pipelines at video rates, and the 12 Kbit EAB RAM provides line buffers for 1D spatial filters. The PQFP-208 footprint fits the original through-hole prototype boards of older imaging carts. The 2.5V core keeps power dissipation modest, important in cart-mounted medical equipment. This application preserves clinical workflow continuity by re-using proven sensor analog front-ends while modernizing only the digital correction path.

Education and FPGA Training Platforms
The EP1K10QC208-3 is widely used in university and vocational FPGA training labs because it is a real, in-production PQFP-package device that students can probe and solder by hand, unlike modern BGAs. The 576 LEs fit classic course lab exercises: counters, UARTs, simple CPUs, VGA controllers, and PWM generators. The 'QC' PQFP-208 footprint is large enough for oscilloscope probes. The -3 speed grade lets students meet timing budgets without aggressive optimization. Quartus II Web Edition (legacy) supports the ACEX-1K family free of charge, making the EP1K10QC208-3 an ideal teaching platform for digital logic courses, despite its NRND status.

설계 노트
The EP1K10QC208-3 requires two supplies: a 2.5V core (VCCINT) and a 3.3V I/O (VCCIO). Per the ACEX-1K datasheet, VCCINT must reach 2.5V before or simultaneously with VCCIO during power-up to prevent I/O latch-up. Add a 100 µF bulk capacitor plus 0.1 µF + 10 µF ceramic decoupling on each supply pin pair; place the ceramics within 5 mm of the device. Programming pin (nCONFIG, nSTATUS, CONF_DONE) must be pulled high with a 10 kΩ resistor.
PQFP-208 has a 0.5mm pitch and gull-wing leads; allow at least 1.0mm pad-to-pad clearance for reliable hand-soldering and rework. Use 4-layer PCB with continuous ground plane under the device to minimize EMI from the 200 MHz internal clock. All unused I/O pins must be set to logic-low output (not input) in the Quartus pin assignment to prevent oscillation. JTAG chain: connect TCK, TMS, TDI, TDO to a 4-pin header with 10 kΩ pull-ups on TCK and TMS.
Do not assume the EP1K10QC208-3 is bitstream-compatible with the EP1K100QC208-3N even though both share the PQFP-208 package: the device ID differs and Quartus must re-target the project. The 'N' suffix denotes Pb-free plating only, not functional changes. The device is NRND - do not design new products around it; choose Cyclone IV or MAX 10 instead. Configuration EPROM must be EPC2LC20 or compatible; older EPC1 devices do not support the 2.5V ACEX-1K core.
Estimated: At typical toggle rate of 30% and 25°C ambient, the EP1K10QC208-3 dissipates approximately 0.4 W. With PQFP-208 theta_JA around 35°C/W, junction temperature rise is ~14°C above ambient. No heatsink required, but provide thermal vias to the inner ground plane beneath the exposed die pad region (note: PQFP-208 does not have a true e-pad; copper pour in the package keep-out zone is the primary heat dissipation path).
