Typical Applications
EP1K100QC208-2N is suitable for 6 applications: Communications Protocol Bridge, Industrial I/O and Machine Control, Video and Image Preprocessing, Test and Measurement Data Acquisition, Legacy System Lifecycle Replacement, SOPC / Soft Processor Subsystem.
Communications Protocol Bridge
The EP1K100QC208-2N is well suited for protocol bridging because its 147 user I/O can connect parallel legacy buses, UARTs, SPI and simple memory interfaces on the same device. The 4,992 logic elements implement FIFO controllers, packet parsers, CRC generators and bridge state machines without an external processor. Its 49,152 RAM bits can buffer packets or store small descriptor tables, reducing external SRAM count. At the -2 speed grade, typical byte-lane or serial bridge designs close timing comfortably below 100 MHz, simplifying PCB layout. Placed between a 3.3V I/O domain and 2.5V core, the device needs a 3.3V VCCIO rail and a 2.5V VCCINT rail. An EPC2 configuration device can make the bridge self-starting on power-up, an important reliability feature in telecom line cards.
Recommended
Industrial I/O and Machine Control
In industrial control cards, the EP1K100QC208-2N can implement sensor input debounce, quadrature decoder logic, PLC-style output latching and fail-safe interlock logic. The 147 I/O pins allow direct connection to optocoupler inputs and transistor output stages, reducing glue components between the sensor interface and an external host processor. Commercial 0C to 70C operation suits indoor equipment racks and enclosed PLC cabinets with moderate airflow. Because the core is 2.5V and CMOS, idle power is modest compared with older 5V programmable logic. The 4,992 LEs provide ample resources for state-machine control, and 49,152 RAM bits can hold recipe tables or alarm logs. Use an EPC2 configuration device so the machine controller boots into a safe, defined state before the host CPU starts.
Recommended
Video and Image Preprocessing
The EP1K100QC208-2N is appropriate for low-cost video preprocessing because it can perform pixel pipeline operations in parallel. Its 49,152 RAM bits can implement small line buffers for 3x3 convolution windows, and the 4,992 logic elements can handle thresholding, color-space conversion simple edge detection or pattern-of-interest windowing. A 2.5V core minimizes high-frequency switching noise on the pixel clock rail, important for maintaining image quality. The 208-pin PQFP provides enough I/O for a parallel camera bus plus output FIFO. At -2 speed, pixel clocks up to roughly 50-80 MHz are practical for moderate-resolution cameras. External video DACs or memory controllers still require glue logic, but the FPGA reduces the overall component count in legacy CCTV and industrial inspection modules.
Recommended
Test and Measurement Data Acquisition
For benchtop instruments and custom DAQ boards, the EP1K100QC208-2N provides flexible glue logic between ADCs, DACs, counters and an embedded processor. The 147 user I/O can implement parallel AD7874-style converter buses, trigger routing and time-stamp counters. Its 4,992 logic elements are enough for a small FIFO controller and custom measurement state machine. The 49,152 RAM bits can store acquisition windows or act as a circular buffer for sporadic trigger events. The commercial temperature range fits indoor test equipment that is temperature-stabilized. Power dissipation is low enough for a 2.5V rail generated from a small LDO; however, designers must retain the external configuration source. For migrating an existing ACEX product, the -2N provides balanced speed and lead-free availability.
Recommended
Legacy System Lifecycle Replacement
The EP1K100QC208-2N is often used to replace the same MPN in equipment already deployed, because its 208-pin PQFP footprint and pinout are fixed by the original PCB. Field-service teams can substitute the -1N, -1 or -3N speed grades when the original -2N is unavailable, since all are pin-compatible and electrically compatible enough for many systems. The lead-free N suffix is beneficial for rework requiring modern solders. This application is about extending product life rather than new feature development. Prior to substitution, verify the configuration bitstream; if the original .sof/.pof was compiled for the same device family and pinout, it may work, but recompiling through Quartus II for the exact speed grade is safest.
Recommended
SOPC / Soft Processor Subsystem
The ACEX 1K family was marketed as a low-cost system-on-a-programmable-chip platform, and the EP1K100QC208-2N can host small soft processors and memory-mapped peripherals. Its 4,992 logic elements are sufficient for a small Nios or custom 8/16-bit processor core, address decoding, UARTs and interrupt controllers. The 49,152 RAM bits are split among embedded array blocks to provide code and data storage without external SRAM. At -2 speed, a modest soft-core processor can execute control code while the FPGA simultaneously handles high-speed parallel I/O. Because ACEX 1K is SRAM-based, system designers must reset the processor into a valid state and load configuration from EPC1/EPC2. This architecture suits protocol converters needing both software flexibility and parallel hardware acceleration.

Key Differentiators
- The -2N offers a lead-free-compatible N suffix at the most common speed grade for legacy ACEX 1K stock (vs EP1K100QC208-2)
- Provides an intermediate timing option that balances cost and speed in the ACEX 1K QC208 family (vs EP1K100QC208-3N)
- Same die, same pinout, same package across the EP1K100QC208 speed variants, allowing field substitution (vs EP1K100QC208-1N)
Design Notes
The EP1K100QC208-2N core rail is 2.5V, while I/O banks typically run at the interface voltage, commonly 3.3V. Decouple each VCC and VCCIO pin group with a 0.1uF ceramic capacitor and provide 1uF to 10uF bulk capacitance near the package. Estimated: if the configured design uses roughly 60% of logic and internal toggling, core current may be on the order of 0.2A to 0.5A, so the 2.5V supply should be rated for at least 1A. Keep the 2.5V plane separate from the 3.3V I/O plane to prevent noise coupling into the FPGA core.
The ACEX 1K EP1K100 is SRAM-based and has no nonvolatile configuration memory. If you omit an EPC1/EPC2 configuration device or fail to drive configuration from a host, the FPGA will not implement the intended logic after power-up. During configuration, I/O pins are typically tri-stated, so outputs connected to powered loads must have external pull-ups or enable logic to avoid indeterminate states. After configuration, verify CONF_DONE goes high and INIT_DONE behavior matches the ACEX 1K datasheet before releasing the board to production.
The 208-pin PQFP has a fine lead pitch, typically 0.5 mm on a 28 mm square body; follow manufacturer footprint recommendations for pad size and solder paste. Use 4-6 mil traces for fanout between leads, and place via-in-pad only if the assembly house supports it. A solid ground plane under the package is critical, and a thermal relief pattern should connect the large pad areas while maintaining electrical integrity. Add test points for the 2.5V and 3.3V rails and for key configuration signals DCLK, DATA0, nCONFIG and CONF_DONE.
Compliance Information
The N suffix in Altera naming often indicates a lead-free finish, but the verified web data did not provide an explicit RoHS certificate or compliance statement. End-of-life status is confirmed by distributor/GlobalSpec records.
