EP20K200EQI240-2 - APEX 20KE FPGA | Altera | 240PQFP

Industrial Control and Factory Automation

The EP20K200EQI240-2 fits industrial control systems by combining 8,320 logic elements and 168 I/Os with an industrial temperature rating. In a PLC or motion controller, the FPGA can implement high-speed encoder counting, PWM generation, and custom fieldbus bridging with deterministic parallel I/O. The 1.8 V core and 0.22 µm process help limit power in sealed industrial enclosures, while the 240-pin BFQFP provides enough routing for multiple motor-driver interface signals. When implementing safety interlocks, the FPGA can execute parallel redundancy checks that a sequential MCU would struggle to handle at speed. Designers should pair this FPGA with an external configuration device and provide clean 3.3 V or 5 V I/O level-shifting for legacy industrial sensors.

Telecommunication Line Card Logic

The EP20K200EQI240-2 is suited to telecom line cards because its 106,496 RAM bits and 205 MHz internal clock support packet buffering, cell processing, and simple MAC/PHY bridging. The 168 user I/O signals can connect to a backplane bus, PHY devices, and a control processor without external CPLD glue. The embedded system blocks can be configured as FIFOs to absorb burst traffic, reducing demand for external SRAM. Using the I-suffix variant allows the line card to operate in central office environments with elevated ambient temperatures. For frame-based protocols such as 100 Mb/s Ethernet, designers can implement a lightweight MAC state machine and interface directly to a 10/100 PHY using LVCMOS signaling; the APEX-20KE provides the port count and internal RAM depth needed for small per-port queues.

Video and Image Interface Processing

In video capture or display boards, the EP20K200EQI240-2 accepts parallel pixel data from CMOS sensors or video decoders, applies line-buffer delays in embedded RAM, and performs simple scaling or color-space conversion before transmission to a display controller or DSP. Its 8320 logic elements are sufficient for 2D raster operations, while 168 I/Os accommodate 24-bit RGB buses, sync signals, and a host-interface. The 106,496 memory bits serve as scan-line buffers, reducing the need for separate FIFO chips. The -2 speed grade supports pixel clocks up to roughly 150–200 MHz, well above standard XGA/HD formats. The industrial temperature grade is also valuable when cameras are placed near motors or other heat sources. Care must be taken with clock-domain crossing between incoming pixel clock and the local FPGA clock to avoid metastability.

ASIC Prototyping and Verification

The EP20K200EQI240-2 is a cost-effective prototyping vehicle for ASIC blocks that require up to 200K system gates. Designers can map RTL intended for a standard-cell ASIC into the FPGA using the same synchronous design methodology, then verify boot code and interface timing in real hardware. The 168 user I/Os allow bridging to the target SoC bus, external SRAM, and host PC through a JTAG or parallel port. Because the FPGA is SRAM-based, iterative builds are fast, and the 240-pin BFQFP can be soldered onto a small daughtercard for bench experiments. The 0.22 µm process imposes timing differences from a newer ASIC process, so engineers should include timing margin and use the -2 speed grade to approximate final system clocks.

Test and Measurement Equipment

The EP20K200EQI240-2 is well matched to waveform generators, logic analyzers, and custom measurement front-ends. Its parallel I/O structure can create stimulus patterns, interface to high-speed ADCs/DACs, and decode digital buses with custom trigger logic. The 8,320 logic elements can hold small signal-processing chains, while embedded RAM implements acquisition buffers or pattern memory. The industrial temperature rating supports benchtop instruments in factory environments that see heat from nearby power supplies. Because the FPGA can be reconfigured over JTAG, instrument firmware can load different measurement personalities into the same hardware, reducing board variants. For data acquisition, design a synchronous sample clock fan-out and use the FPGA’s internal PLLs, if available in the APEX-20KE family, to align multiple channels.

Aerospace, Defense and Rugged Electronics

EP20K200EQI240-2 is often considered for rugged, high-reliability systems because the I-suffix extends the operating temperature and Altera/Intel APEX-20KE parts have a long history in military-grade programs. The FPGA can implement custom encryption, bus bridging, sensor processing, and redundant control logic in a single device. Its 1.8 V core reduces power budget pressure in conduction-cooled enclosures, while the 240-pin BFQFP allows reliable soldering without the inspection difficulty of large BGA columns. The 0.22 µm technology may be older, but it provides predictable single-event effects data for heritage designs. When used in avionics or defense projects, the designer should follow IPC-2221 and AEC-like derating guidelines, even though the part itself is not AEC-Q100 qualified.
