Typical Applications
EP1K100FC484-2NGZ is suitable for 6 applications: Telecom Line-Card Glue Logic, PCI Add-in Card Controller Logic, Industrial Control and Machine Interface, ASIC Replacement / Low-Volume Production, Legacy Development and Education Platforms, Parallel Bus Bridging and Memory Interface.
Telecom Line-Card Glue Logic
The EP1K100FC484-2NGZ fits telecom line cards because its 4,992 LEs and 333 user I/Os are sized exactly for backplane glue, bus-bridging and protocol adaptation between TDM framers, Ethernet MACs and ASIC/ASSP front-ends. The 2.5 V core with PCI-compliant 3.3 V I/O allows direct interface to legacy PCI bus devices without external level shifters. Its 49,152 bits of embedded SRAM in EABs handle small FIFOs and look-up tables for routing tables without external memory, simplifying BOM and reducing board area on dense line cards.
Recommended
PCI Add-in Card Controller Logic
The EP1K100FC484-2NGZ is widely deployed on PCI add-in cards because it natively supports 33 MHz/66 MHz, 32-bit/64-bit PCI with on-chip PCI-compliant I/O buffers and the dedicated nCONFIG/nSTATUS/CONF_DONE configuration chain. With 100K gates and 333 I/Os, it implements state machines, scatter-gather DMA engines and bus-master controllers in a single device. The 0-70C commercial temperature grade suits PCI cards installed in climate-controlled servers and desktops; designers should still observe 2.5 V core and 3.3 V PCI signaling rules in timing closure.
Recommended
Industrial Control and Machine Interface
For industrial control front-ends and HMI panels, the EP1K100FC484-2NGZ provides enough logic and 333 I/Os to drive parallel LCD/TFT interfaces, keypads, motor-control PWM and serial fieldbus bridges (Modbus, Profibus, CAN) in a single chip. The 49,152-bit on-chip memory stores waveform tables, character fonts and small protocol stacks without external SRAM, reducing BOM cost. Although the commercial 0-70C temperature grade suits panel-internal environments, designs destined for outdoor or factory-floor deployment should select the EP1K100FI484-2 industrial variant.
Recommended
ASIC Replacement / Low-Volume Production
The EP1K100FC484-2NGZ is a classic ASIC-replacement vehicle for low-volume production (typically 100 to 10,000 units) where the NRE of a full ASIC is uneconomic. With 100,000 system gates, 49,152 bits of EAB RAM and SRAM-based in-system programmability, designers can iterate firmware-equivalent (bitstream) updates post-deployment via JTAG or Altera EPC configuration ROMs. Although now Obsolete, distributor stock of the EP1K100FC484-2NGZ remains available for re-spin of legacy designs until inventory is exhausted.
Recommended
Legacy Development and Education Platforms
The EP1K100FC484-2NGZ remains in university curricula and legacy development kits that teach SRAM-based FPGA architecture, JTAG configuration, and the Altera MAX+PLUS II/Quartus design flow. Its 484-FBGA is large enough for students to practice fine-pitch BGA rework and pin-constrained floorplanning while staying within the 100K-gate complexity sweet spot. Because the part is supported in older Quartus II service packs and legacy MAX+PLUS II software, it is ideal for coursework that targets Altera/Intel legacy FPGA design entry.
Recommended
Parallel Bus Bridging and Memory Interface
The EP1K100FC484-2NGZ is well suited to bridge between legacy parallel buses (e.g. PC/104, VME, ISA, proprietary 16/32-bit backplanes) and modern peripherals or processors, thanks to its 333 user I/Os. The 49,152-bit EAB SRAM implements small dual-port buffers and FIFOs that decouple mismatched bus clocks, while 4,992 LEs handle the address decoding, byte-enable logic and interrupt glue. Designers using the part should pay attention to the 2.5 V core and 3.3 V I/O voltage domains and use series-resistor or level-translator techniques for 5 V legacy buses.

Key Differentiators
- Same die, same 484-FBGA, same -2 speed grade - bit-for-bit drop-in (vs EP1K100FC484-2N)
- Speed-grade upgrade on the same footprint (vs EP1K100FC484-1N)
- Industrial-temperature variant on same footprint (vs EP1K100FI484-2)
- Enhanced industrial variant with 5 V tolerant I/O (vs EP1K100EFI484-2)
Design Notes
Estimated: The EP1K100FC484-2NGZ core operates from 2.5 V; I/O banks support 3.3 V PCI signaling. A typical 50% utilization design with all 333 I/Os toggling draws roughly 0.5-1.0 A from the 2.5 V rail, so design the LDO (e.g. 2.5 A buck) with adequate headroom. Decouple each VCCINT/VCCIO ball pair with 0.1 uF plus 10 uF bulk within the ball-grid escape radius.
The 484-FBGA uses 1.0 mm ball pitch on a 23x23 mm body; escape routing requires microvia (HDI) stack-up with at least 4-6-4 build-up layers. Use via-in-pad or dog-bone fan-out per the Altera BGA escape guidelines, and follow the ACEX-1K pin table for VCC/VSS ball placement to keep power planes contiguous.
Configuration mode pins (MSEL0, MSEL1) select between EPC serial, JTAG and Fast Passive Parallel modes - wiring them incorrectly is the #1 reason ACEX-1K boards fail to configure. Also ensure CONF_DONE is pulled high via 10 kohm and nCONFIG/nSTATUS are properly debounced. Without an EPC configuration ROM, the SRAM configuration is lost on every power cycle.
Estimated: at 100% utilization and 333 I/Os switching at 33 MHz PCI, expect 1.5-2.5 W dissipation in still air. The 484-FBGA has no exposed die pad; thermal relief relies on PCB copper pour under the package. Use at least 4 thermal vias (0.3 mm drill) under the central ball grid to inner-plane copper for 15-20 C/W theta_JA improvement.
Compliance Information
"N" suffix historically denotes lead-free terminal finish per Altera/Intel legacy part-number convention, but a current RoHS/REACH CoC must be requested from the distributor. AEC-Q100 not applicable - this is a commercial/industrial FPGA, not an automotive-qualified IC.
