EP1K100QI208-2N 개요
An FPGA is a semiconductor device containing programmable logic blocks and programmable interconnects that can be configured after manufacturing to implement arbitrary digital logic. FPGAs sit above CPLDs in logic capacity and are widely used where ASIC development cost is prohibitive, or where in-field logic updates are needed. In the programmable logic hierarchy, this ACEX-1K device belongs to the Altera FPGA family, from the older high-density programmable logic product class that also includes MAX, FLEX, and Cyclone families.
Key features confirmed by the DigiKey and Mouser listings include 4,992 logic elements arranged in 624 LABs, 49,152 total RAM bits, 147 user I/Os, and a 208-BFQFP package. The industrial temperature option and Pb-free finish make the EP1K100QI208-2N attractive for extended-temperature legacy boards that must still meet modern lead-free assembly rules. The ACEX-1K family is a 2.5 V core FPGA solution and provides embedded memory blocks for FIFOs, distributed RAM, and ROM functions.
The EP1K100 architecture uses a look-up-table-based logic element fabric with fast carry chains, plus dedicated embedded array blocks for memory-rich designs. The -2 speed grade is a mid-range performance option; faster -1 and slower -3 grades exist in the same package, allowing board-level speed migration without changing the PCB footprint. The 208-pin BFQFP package provides enough I/Os for local bus interfaces, memory controllers, and moderate parallel processing tasks while simplifying manufacturing compared with fine-pitch BGA packages used by larger ACEX devices.
Typical uses include industrial control I/O boards, video/imaging preprocessing, communication interface bridging, test instruments, and system power-management sequencing logic. Because the device can be reconfigured, it is also suitable for prototyping glue logic in mixed-signal designs.
When designing with the EP1K100QI208-2N, remember to place a configuration device or download cable header close to the FPGA and reserve enough board area for the 2.5 V core regulator and I/O bank supplies. Board-level pin migration between -1, -2, and -3 speed grades in the same 208-pin package is possible, but always verify the exact configuration bitstream and timing closure after changing speed grade.

일반적인 애플리케이션
EP1K100QI208-2N 적합 용도: 6 애플리케이션s: Industrial I/O Control, Communication Interface Bridge, Video and Imaging Preprocessing, Test and Measurement Instruments, Legacy System Replacement, Embedded Motor Control.
Industrial I/O Control
The EP1K100QI208-2N suits industrial I/O cards that need a flexible 147-pin FPGA to implement parallel bus multiplexing, input debouncing, and PLC-style glue logic. Its 4,992 logic elements allow moderate state machines while the 49,152 RAM bits buffer status registers. The industrial temperature option keeps timing stable in enclosures that see wide thermal swings. Place the FPGA near the backplane connector and route I/O banks to matching standard levels. Because the ACEX-1K core is 2.5 V, a local regulator is recommended when the backplane is 3.3 V or 5 V.
추천
Communication Interface Bridge
FPGAs are commonly used as protocol bridges between legacy parallel buses and newer serial interfaces. The EP1K100QI208-2N provides 147 user I/Os for address/data buses, control signals, and sideband handshaking. Its embedded RAM bits can form small FIFOs that absorb rate mismatch without external memory. The -2 speed grade is adequate for moderate clock rates used in 8-bit and 16-bit bus bridging. Designers should include external termination and series resistors on fast buses, and avoid overconstraining I/O timing without completing a static timing analysis in the ACEX-1K design flow.
추천
Video and Imaging Preprocessing
Video frame grabbers and imaging front ends often use a mid-density FPGA for pixel alignment, line buffering, and simple filtering before sending data to a DSP or ASIC. The EP1K100QI208-2N has enough logic elements for shift registers, 3x3 convolution kernels, and ROI extraction, while its 49,152 RAM bits can hold multiple scanline buffers. The 147 I/O pins directly connect to CMOS image sensors or video ADCs. The core 2.5 V supply should be filtered with a low-noise regulator, and separate digital and analog grounds on the PCB will preserve image quality.
추천
Test and Measurement Instruments
Bench instruments, data acquisition modules, and logic analyzers use FPGAs for trigger logic, sample-rate conversion, and front-panel control. The EP1K100QI208-2N's 4,992 logic elements are enough to implement digital triggers and decimation filters, while 147 I/Os allow direct connection to ADCs, DACs, and LCD interfaces. Its industrial temperature grade improves reliability in benchtop environments with restricted airflow. Use the FPGA configuration device or a passive serial download cable in the test fixture so firmware can be updated without opening the instrument enclosure.
추천
Legacy System Replacement
The ACEX-1K EP1K100 family appears in many fielded designs that now face difficult supply-chain decisions. The EP1K100QI208-2N can be used as a replacement on existing 208-BFQFP footprints, particularly where the original non-Pb-free or commercial-temperature variant is no longer stocked. Because the package and pinout are shared with other EP1K100 QFP variants, the same PCB can be assembled with a speed-grade or temperature-grade alternative selected during final test. Verify the configuration bitstream and timing before replacing an older unit in the field, and update the configuration device if the .rbf or .pof file changes.
추천
Embedded Motor Control
Motor-control boards use FPGAs to implement PWM generation, quadrature encoder decoding, and fault logic with deterministic timing. The EP1K100QI208-2N can generate multiple PWM channels and perform dead-band insertion in hardware, reducing the real-time load on the controlling MCU. Its 147 I/Os connect to gate drivers, current sensors, and encoder inputs. The industrial temperature grade is useful in motor drives with high ambient heat. Route high-current PWM traces away from the FPGA's 2.5 V core plane and add hardware overcurrent latching to avoid firmware-dependent shutdown faults.

설계 노트
Estimated: the EP1K100QI208-2N core uses a 2.5 V supply, and total ACEX-1K power depends on logic utilization, clock rate, and I/O loading. For a mid-density design with ~50% logic utilization and a 50 MHz clock, budget at least 100–200 mA for the core plus additional I/O bank current. Use a low-dropout regulator with 10 uF input and output capacitance. Do not rely on this estimate for production thermal analysis; simulate with the ACEX-1K power estimator or measure on the final board.
The 208-BFQFP package has a 0.5 mm pitch and is supplied as a tray part. Place decoupling capacitors within 3–5 mm of each VCC/GND pin pair, using at least one 0.1 uF ceramic per pair and a 10 uF bulk capacitor near the package. Keep the 2.5 V core plane continuous under the FPGA and avoid routing high-speed switching signals under the exposed leadframe area. For reliable soldering, follow the IPC-7525 stencil and JEDEC reflow recommendations for 0.5 mm QFP packages.
The ACEX-1K family is obsolete, and the original Altera Quartus/MAX+PLUS II toolchains are not current. Before using EP1K100QI208-2N in a new design, verify that your configuration device and download cable are still supported by your installation. If the legacy .rbf or .pof file is missing, reverse-engineering the bitstream may be impossible. Also confirm bank voltage compatibility: a 2.5 V core does not imply that all I/O banks automatically tolerate 5 V signals.
