EP20K100EQI240-2X Overview
An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines lookup-table (LUT) logic, product-term logic, and embedded memory blocks on a single die, enabling system-on-a-programmable-chip (SOPC) integration. APEX-20KE belongs to the broader PLD taxonomy: PLD -> FPGA -> SRAM-based FPGA -> APEX-20KE family. This hierarchical integration is critical for high-density, register-intensive designs such as custom datapaths, glue logic, and DSP pre/post-processing.
Key features include the MultiCore architecture combining embedded array blocks (EABs), logic array blocks (LABs), and FastTrack interconnect, LVDS I/O support for high-speed differential signaling, and built-in boundary-scan (JTAG/IEEE 1149.1) for board-level testability. The device is specified for industrial temperature range (–40 °C to +85 °C) and supports in-system programmability via the serial configuration scheme.
The APEX-20KE architecture integrates look-up table logic with product-term logic and dedicated embedded memory, providing a flexible platform for designs that mix glue logic with on-chip buffering. The 0.22 µm process combined with the FastTrack continuous routing fabric enables predictable timing closure at clock frequencies up to the datasheet-rated maximum.
Typical applications include telecommunications line cards, industrial motor control pre-processing, custom glue logic between microprocessors and peripherals, and bridge/controller interfaces. It is widely used in legacy systems that require LVDS signaling alongside a large general-purpose logic fabric.
When designing with this device, ensure the configuration scheme (typically serial or parallel) and clock-distribution strategy align with the Quartus II design flow. The I/O banks must be powered with voltages compatible with downstream devices, and JTAG pins should be reserved for in-system programming and board-test access.

Typical Applications
EP20K100EQI240-2X is suitable for 6 applications: Telecommunications Line Cards, Industrial Motor Control Pre-Processing, Glue Logic Between Microprocessor and Peripherals, Custom Bridge and Controller Interfaces, Legacy PCI Card Designs, Test and Measurement Instrumentation.
Telecommunications Line Cards
The EP20K100EQI240-2X suits telecom line cards thanks to its 100K system gates, 53,248 bits of embedded memory, and LVDS I/O support. Its 183 user I/O pins handle multiple backplane interfaces in parallel, while the FastTrack interconnect fabric ensures predictable timing for serializer/deserializer glue logic and framing controllers. Industrial temperature grade (-40 C to +85 C) makes it suitable for outdoor-mounted DSLAMs and central-office equipment.
Recommended
Industrial Motor Control Pre-Processing
The EP20K100EQI240-2X is well-matched to industrial motor-control pre-processing boards where it generates PWM timing, decodes encoder feedback, and conditions Hall-effect sensor inputs before handing off to a DSP or microcontroller. Its 1.8 V core consumes modest power while the LVCMOS I/O banks drive 3.3 V gate drivers directly. Industrial temperature grade ensures reliable operation across factory-floor ambient conditions.
Recommended
Glue Logic Between Microprocessor and Peripherals
The EP20K100EQI240-2X excels at custom glue-logic integration between a host microprocessor and mixed-voltage peripherals. With 183 I/O supporting LVTTL, LVCMOS, PCI, and GTL+ simultaneously, it can bridge a 3.3 V CPU bus to 5 V legacy peripherals without external level shifters. The 4,160 logic cells comfortably accommodate wide decode, handshake, and bus-arbitration functions on a single die.
Recommended
Custom Bridge and Controller Interfaces
The EP20K100EQI240-2X is ideal for custom bridge and controller interface designs where protocol translation is required. Its MultiCore architecture combines lookup-table logic, product-term logic, and embedded memory blocks, allowing state-machine implementations, FIFO buffering, and protocol conversion to coexist on the same die. The 250 MHz internal clock supports high-speed serial bridge channels.
Recommended
Legacy PCI Card Designs
The EP20K100EQI240-2X includes dedicated PCI-compatible I/O, making it an excellent choice for legacy PCI add-in card designs in industrial PCs, test instruments, and data-acquisition boards. Its 183 I/O comfortably handle a 32-bit/33 MHz PCI bus plus auxiliary peripheral interfaces, while the 53,248 bits of embedded memory provide bus-master DMA buffering without external SRAM.
Recommended
Test and Measurement Instrumentation
The EP20K100EQI240-2X is a strong fit for test and measurement instruments such as logic analyzers, protocol analyzers, and ATE pin-electronics where custom timing generators and pattern sequencers must coexist with high-speed I/O. Its 250 MHz internal frequency and LVDS support enable fine-grained timing control for stimulus generation and response capture. Industrial operating range suits laboratory and field-test environments.

Key Differentiators
- Industrial temperature grade (-40 C to +85 C) versus commercial alternatives (vs EP20K100EQC240-2X)
- Higher speed grade -2X for tighter timing margins (vs EP20K100EQC240-3N)

Design Notes
The EP20K100EQI240-2X requires a regulated 1.8 V core supply within 1.71 V to 1.89 V. Estimated: at typical dynamic utilization of 50 percent toggle rate and 25 percent logic, core current can approach 200-400 mA depending on clock frequency and embedded array block (EAB) usage. Use a low-dropout regulator with at least 10 percent headroom margin and place decoupling capacitors (0.1 µF and 10 µF bulk) close to every VCCINT pin to suppress switching noise on the core rail.
The 240-pin PQFP package has a 32x32 mm body with 0.5 mm pitch gull-wing leads. Use at least 4-layer PCB stackup with dedicated ground and power planes. All VCCINT and GND pins must be connected; missing power pins cause logic errors and may damage the device during configuration. Route JTAG signals (TCK, TMS, TDI, TDO) with 4-8 mil traces and series-termination near the FPGA to prevent configuration failures.
A common pitfall is assuming LVDS support is automatic across all I/O banks - confirm each I/O bank voltage (VCCIO) matches the downstream device supply before assigning LVDS pairs. Another frequent error is leaving MSEL pins floating; MSEL0/MSEL1 must be tied high or low to select the configuration mode (serial, parallel, or passive). Also ensure nCONFIG is held low during power-up until the 1.8 V rail stabilizes, otherwise the device may enter an undefined configuration state.
The 183 user I/O pins route through the FastTrack continuous interconnect; for LVDS signaling, keep trace lengths matched within 150 mil and use 100 ohm differential termination at the receiver. For 33 MHz PCI interfaces, observe the 32-bit bus length-matching rules and source-termination on clock lines. Always simulate signal integrity with the IBIS model provided in the Quartus II library before final layout.
