Typical Applications
EP1K50QI208-2N is suitable for 6 applications: Legacy Industrial Controller, Communication Protocol Bridge, Medical Monitoring Instrument, Test and Measurement Instrument, ASIC Replacement and Legacy Product Support, Power and Energy Controller.
Legacy Industrial Controller
The EP1K50QI208-2N is a good fit for a programmable logic controller's backplane and I/O manager. Its 147 user I/O pins read encoder counters, handshake to isolation buffers, and control 16-bit parallel busses; 2,880 logic elements implement the PLC scan state machine. The 40,960 bits of memory buffer HMI messages and recipe data. With a -2 speed grade, the device meets typical 10-20 ns backplane cycles. The industrial I temperature option is important when the PLC is installed in a cabinet without air conditioning. Place the FPGA near the backplane connector and keep the 2.5 V core plane clean. The part supports reconfiguration through a configuration EEPROM, simplifying firmware updates in the field.
Recommended
Communication Protocol Bridge
In communication bridge applications, the EP1K50QI208-2N can translate between parallel buses and simple serial streams using 2,880 logic elements for FIFO control and address decoding. The 147 I/O pins connect to SRAM, dual-port memories, and several byte-wide interfaces. The 40,960-bit embedded memory supports small packet buffers. Because the core supply is only 2.5 V, power is reduced in line cards where heat is a concern; however, I/O may need 3.3 V translators depending on the PHY. The industrial grade improves reliability in central-office installations. For a 100 MHz data path, the -2 part is usually sufficient; timing should be verified after layout with the vendor timing analyzer.
Recommended
Medical Monitoring Instrument
The EP1K50QI208-2N can serve as glue logic in patient-monitoring instruments that need deterministic sampling and parallel ADC interfaces. Its 147 I/O pins and 2,880 logic elements capture 12- or 16-bit sample data from multiple ADCs, implement simple digital filters, and drive a host processor memory bus. The 2.5 V core and 0.22 um process keep power modest for portable carts. Since medical approval often requires validated firmware and controlled BOM changes, this legacy FPGA may be used in existing products; for new designs, a more current FPGA family is recommended. Designers should ensure isolation boundaries are on the daughterboard side so the FPGA ground plane stays clean.
Recommended
Test and Measurement Instrument
ATE instruments and benchtop meters use programmable logic for trigger routing, data formatting, and timing generation. The EP1K50QI208-2N's 147 single-ended I/O support ribbon-cable interfaces and front-panel buttons, while 2,880 logic elements implement sequencers. The 40,960-bit RAM serves as a waveform lookup or sample FIFO. At 2.5 V core, power-supply design is simplified. I/O pins can connect to ADC/DAC converters on mezzanine cards. Because the FPGA is volatile, an EPC2 configuration PROM should be provided on the instrument main board so operation begins immediately at power-on. For slower instruments below 50 MHz digital, this logic density is sufficient; faster scopes will need a larger FPGA.
Recommended
ASIC Replacement and Legacy Product Support
Design teams sometimes need bit-stream-compatible glue logic in place of an obsolete gate-array ASIC. The EP1K50QI208-2N provides about 50,000 typical gates and reconfigurable resources that can approximate timing of legacy ASIC macros, although pin mapping is not automatic. It is especially useful for derivative products that reuse an existing 208-pin QFP board layout; firmware can be updated without changing the PCB. The N lead-free version is preferred for RoHS-restricted markets, while the non-N EP1K50QI208-2 may be selected in defense or high-reliability applications requiring tin-lead solder. When migrating code, use vendor synthesis tools to constrain clock domains and I/O standards.
Recommended
Power and Energy Controller
In solar inverters and industrial power controllers, the EP1K50QI208-2N can manage multiple ADC channels for current and voltage monitoring and implement protection state machines. The 40,960-bit memory stores short fault records, and the 147 I/O drive optocoupler outputs and relay-driver interface logic. The 2.5 V core means a simple regulator is sufficient. Industrial-grade screening suits rooftop or utility cabinets where daytime heat is high. The relatively large QFP package is compatible with wave-soldering and inspection processes used in power-electronics manufacturing. For galvanic isolation, place the FPGA on the low-voltage control side and communicate through digital isolators to the power stage.

Key Differentiators
- Industrial temperature grade in a 208-pin ACEX-1K QFP (vs EP1K50QC208-2N)
- Lead-free / RoHS-compliant finish for regulatory markets (vs EP1K50QI208-2)
- Balanced -2 speed grade for legacy timing closure (vs EP1K50QC208-3N)
Design Notes
The EP1K50QI208-2N uses a 2.5 V core supply. Place a 0.1 uF ceramic capacitor at each VCC and VCCIO pin and a 10 uF bulk ceramic or tantalum capacitor near the FPGA. Keep decoupling capacitors within 5 mm of the pins. If you use separate VCCIO rails, set each rail to the correct voltage for that I/O bank; the FPGA input thresholds follow the corresponding VCCIO supply. A four-layer PCB with a solid ground plane is recommended because 147 simultaneous outputs create transient switching noise.
For the 208-pin PQFP package, use a stencil with an appropriate aperture for fine-pitch leads and avoid placing vias directly under the body where solder inspection is difficult. Provide test points for JTAG pins TDI, TDO, TMS, TCK and for configuration pins nCONFIG, nSTATUS, CONF_DONE, DCLK, and DATA0. Keep the trace from the configuration device short to minimize signal integrity issues during configuration. If possible, reserve the board area for a programming header even if production uses EPC2.
Estimated: because the 208-pin PQFP has no exposed thermal pad, heat removal depends on package leads, PCB copper, and airflow. If the FPGA drives many outputs at high toggle rates, calculate junction temperature using the ACEX-1K datasheet package thermal resistance and board layout effect rather than assuming unlimited margin. In industrial cabinets without fan cooling, add airflow or a board-level heatsink if the design exceeds moderate power dissipation. This is an estimate for board-planning, not a packaged power limit from the datasheet.
Do not connect 5 V logic outputs directly to the 2.5 V core or to 2.5 V I/O pins unless the FPGA data sheet allows 5 V tolerance. Use a level translator or series resistor plus clamp when needed. Assign unused I/O pins to a defined state to prevent oscillation and extra current draw. When substituting a commercial-temperature QC part for an industrial-temperature QI part, re-check the intended ambient range and timing closure because the suffix changes thermal qualification and sometimes timing grading.
