EP1K50QC208-2 概要
An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and I/O cells, all of which can be reconfigured by the designer after manufacture. FPGAs occupy a unique position in the digital design hierarchy between fixed-function ASICs and software-programmed microcontrollers - they offer hardware-timed parallelism and deterministic latency, which is impossible to achieve in software alone. The ACEX-1K family specifically targeted low-cost, high-volume applications as a system-on-a-programmable-chip (SOPC) integration platform, bridging the gap between small PLDs and high-density FPGAs.
Key features include a 2.5 V core supply, support for embedded array blocks (EABs) implementing dual-port RAM, ROM, or specialized logic functions, in-system programmability via IEEE 1149.1 (JTAG) boundary scan, multi-voltage I/O standards (LVTTL, LVCMOS, PCI), and an operating junction temperature range suitable for commercial deployments. The PQFP-208 footprint supports conventional surface-mount reflow and through-hole-compatible lead frames for prototyping.
The ACEX-1K architecture uses a continuous SRAM configuration cell that must be loaded at power-up from an external serial or parallel PROM (such as an EPC2 or EPC16 configuration device). The device integrates lookup tables (LUTs), fast carry chains for arithmetic, cascade chains for wide fan-in logic, and a tristate network for bus-oriented designs - providing megafunction-equivalent density at lower cost than the contemporary FLEX 10K family.
Typical applications include industrial glue logic, communication protocol bridging, low-to-medium density state-machine controllers, motor-control co-processors, flat-panel display timing controllers, and legacy PCI bus interface cards. The combination of 50K gates, embedded memory, and 147 I/Os makes it a versatile platform for system integration tasks where dedicated ASICs are uneconomical.
When designing with the EP1K50QC208-2, ensure the configuration memory device is correctly selected for the chosen configuration scheme (PS, AS, or JTAG). The PQFP-208 package has limited thermal dissipation capability compared to BGA equivalents; for designs operating near full logic utilization, evaluate timing closure in Quartus II using the slowest commercial speed-grade derating.

主な用途
EP1K50QC208-2 の用途: 6 件s: Industrial Glue Logic and Protocol Bridging, Flat-Panel Display Timing Controller, Legacy PCI Bus Interface Card, Motor-Control Co-Processor, Communication Protocol Bridge / Converter, Low-Density ASIC Prototyping.
Industrial Glue Logic and Protocol Bridging
The EP1K50QC208-2 is well suited for industrial glue-logic and protocol-bridging applications requiring 50K gates of deterministic hardware-timed logic. With 2,880 logic elements distributed across 360 LABs and 147 user I/Os, the device can host parallel state machines, custom bus interfaces (I2C, SPI, UART), and protocol converters in a single chip. The 2.5 V core and LVTTL/LVCMOS I/O standards allow direct interfacing to legacy 5 V-tolerant devices through external resistive dividers. Compared to a microcontroller, the FPGA delivers guaranteed timing closure and parallel execution - critical for deterministic industrial control loops. This is the classic ACEX-1K use case.
おすすめ
Flat-Panel Display Timing Controller
The EP1K50QC208-2's 147 user I/Os and 200 MHz maximum operating frequency make it a viable timing controller for low-to-mid resolution flat-panel displays (XGA, SXGA, and below). The 360 LABs can implement row/column drivers, color-space converters, and on-screen display (OSD) overlays while the embedded array blocks (EABs) hold line buffers. The PQFP-208 package is friendly to conventional SMT reflow, simplifying panel-side assembly. Designers should pay close attention to I/O timing skew across the four I/O banks when targeting wide parallel RGB interfaces above 65 MHz pixel clock.
おすすめ
Legacy PCI Bus Interface Card
When designing legacy 32-bit/33 MHz PCI add-in cards, the EP1K50QC208-2 delivers sufficient logic density to implement the PCI target interface plus application logic in a single device. The 2.5 V core plus 3.3 V VCCIO for PCI-compliant I/O is supported on the ACEX-1K device bank structure. 147 user I/Os comfortably accommodate the 64-pin PCI bus plus dedicated control signals and board-level glue logic. The PQFP-208 package has a 0.5 mm lead pitch compatible with conventional PCB manufacturing tolerances. PCI timing closure must be verified with Quartus II timing analysis using the PCI megafunction.
おすすめ
Motor-Control Co-Processor
The EP1K50QC208-2 can offload motor-control algorithms (PWM generation, FOC, encoder decoding) from a host microcontroller, executing critical loops in hardware with deterministic sub-microsecond latency. The embedded array blocks provide fast access to lookup tables for sine and Clarke transforms, while the 360 LABs handle the comparator and PWM modulator logic. The 200 MHz maximum frequency supports field-oriented control (FOC) loop rates up to 50 kHz even with multi-axis implementations. PQFP-208's exposed lead frame simplifies heat-sink attachment for high-utilization designs.
おすすめ
Communication Protocol Bridge / Converter
The EP1K50QC208-2 is frequently deployed as a multi-protocol bridge in telecom and datacom equipment - converting between I2C, SPI, UART, parallel buses, and custom proprietary interfaces at line rates up to 200 MHz. With 2,880 logic elements and 40,960 bits of embedded RAM, designers can implement multiple protocol engines concurrently with shared buffer memory in the EABs. The 147 user I/Os handle dozens of peripheral connections on a single chip, reducing board area versus discrete glue logic. Quartus II's MegaWizard generates protocol cores (UART, I2C master/slave, SPI) for rapid development.
おすすめ
Low-Density ASIC Prototyping
Before committing to a masked ASIC, design teams prototype their state machines, datapaths, and bus interfaces on the EP1K50QC208-2 to verify functionality and timing closure. The 50K-gate density matches many small-to-medium ASIC designs, and the PQFP-208 package is reusable as a footprint reference for ASIC package selection. The JTAG interface allows rapid in-system iteration, while the EPC configuration PROM enables field-upgradable prototypes. Quartus II synthesis preserves the same RTL when migrating to a HardCopy II structured ASIC for production volume.

設計ノート
Estimated: The EP1K50QC208-2 core draws approximately 5 mA quiescent and scales up with logic utilization and clock frequency. At full 2880-LE utilization with 200 MHz operation, ICCINT may reach 200-300 mA from the 2.5 V rail. Provide a low-impedance 2.5 V regulator (e.g., LM1117-2.5 or TPS7A4533) with at least 10 µF bulk and 0.1 µF decoupling at each VCCINT pin pair. For I/O banks, VCCIO must be supplied per-bank; bank 3/4 typically use 3.3 V for PCI compatibility.
The PQFP-208 package has a relatively high θJA (approximately 25-30 °C/W without airflow) compared to BGA equivalents. For designs operating above 70 % logic utilization at the maximum 200 MHz clock, attach a small clip-on heatsink or provide at least 200 LFM of forced airflow. Estimated: at 500 mW total power dissipation, the junction temperature rises ~15 °C above ambient with no heatsink and no airflow. Avoid placing the FPGA adjacent to high-power switching regulators; route heat away via copper pours connected to the thermal pad area under the package.
PQFP-208 has a 0.5 mm lead pitch which requires careful PCB layout: use 4-mil traces and 8-mil spaces between leads, with soldermask-defined or non-soldermask-defined pads per assembly house preference. Provide a generous ground pour beneath the package to control return paths and reduce EMI. All VCCINT and VCCIO pins must have a 0.1 µF decoupling capacitor placed within 100 mils of the pin; high-frequency switching I/O banks benefit from an additional 0.01 µF capacitor. Use differential pair routing for clock inputs (CLK0/CLK1) to maintain signal integrity at 200 MHz.
Common pitfalls when designing with the EP1K50QC208-2 include: (1) forgetting to connect nCONFIG and nSTATUS pull-ups to VCCIO during configuration, (2) selecting an EPC configuration PROM that is too small for the compressed bitstream, (3) tying MSEL pins incorrectly for the chosen configuration mode (PS vs AS vs JTAG), (4) exceeding 147 user I/Os when assigning pins in Quartus II pin planner, and (5) mixing 5 V input signals into a 3.3 V VCCIO bank without external clamping. Always run full Quartus II timing analysis at the worst-case PVT corner before committing to layout.
