Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EP1K50TC144-1N is suitable for 6 applications: Low-Cost System-on-a-Programmable-Chip (SOPC) Designs, PCI Bus Interface and Bridge, Industrial Control and Instrumentation, Communications Infrastructure Glue Logic, DSP Coprocessor and Front-End Pre-Processing, Video and Image Processing Front-Ends.
Low-Cost System-on-a-Programmable-Chip (SOPC) Designs
The EP1K50TC144-1N fits SOPC designs because its 2,880 logic elements and 40,960 bits of embedded dual-port RAM allow integration of a soft processor core plus glue logic on a single device. Designers typically instantiate the EAB-based memory blocks to hold firmware or data buffers while using the LAB fabric for peripherals and bus control, achieving a complete subsystem on one FPGA rather than partitioning across multiple chips.
Recommended
PCI Bus Interface and Bridge
The EP1K50TC144-1N's -1 speed grade complies with PCI Local Bus Specification Revision 2.2 at 5.0V operation per the ACEX 1K datasheet. The 102 user I/Os in the TQFP-144 package provide adequate pins for a 32-bit PCI bus (32 data + control) plus side-band signals, while the 199K equivalent gates and 360 LABs accommodate protocol state machines, FIFOs, and bus-master DMA engines without external logic.
Recommended
Industrial Control and Instrumentation
The EP1K50TC144-1N suits industrial control because its CMOS 2.5V core delivers low power dissipation and the TQFP-144 package is hand-solderable for prototype rework. The 102 I/Os are ample for parallel sensor arrays, encoder feedback, PWM outputs, and isolated communication links; meanwhile the embedded RAM and LAB fabric can host custom filtering, control loops, and Modbus or CAN soft-IP without external ASICs.
Recommended
Communications Infrastructure Glue Logic
The EP1K50TC144-1N fits telecom and networking equipment as interface-bridging glue between legacy parallel buses, framing ASICs, and backplane transceivers. Its 180 MHz Fmax, embedded dual-port RAM, and 102 I/Os allow designers to integrate protocol converters, FIFO buffers, and timing-recovery state machines on a single 2.5V device, replacing multiple discrete PLDs and FIFOs while keeping power consumption low.
Recommended
DSP Coprocessor and Front-End Pre-Processing
The EP1K50TC144-1N serves as a DSP coprocessor or pre-processing engine because its embedded array blocks can implement multipliers and dedicated datapath functions alongside general LAB logic. Designers use the 40,960 bits of dual-port RAM as data and coefficient storage while the 2,880 logic elements implement FIR filters, FFT butterflies, and control state machines that offload the host processor.
Recommended
Video and Image Processing Front-Ends
The EP1K50TC144-1N can handle video and image front-end tasks such as line buffering, color-space conversion, and de-interlacing. Its 40,960 bits of embedded dual-port RAM serve as line buffers for CIF and SD-resolution video, while the 102 user I/Os accept parallel ITU-R BT.656 or RGB streams and drive downstream encoders; the 2.5V core and CMOS process keep dynamic power manageable in always-on pipelines.

Key Differentiators
- Balanced density and I/O count for cost-sensitive glue-logic designs (vs EP1K30TC144-1N)
- PCI Local Bus 2.2 compliance at 5.0V operation (vs EP1C6TC144 (Cyclone))
- Same-footprint migration path across speed grades (vs EP1K50TC144-2N)
- Higher embedded RAM density than smaller ACEX 1K siblings (vs EP1K10TC144-1N)
Design Notes
The EP1K50TC144-1N requires separate VCCINT (2.5V core) and VCCIO bank supplies, with each I/O bank having its own VCCIO pin. Designers must provide at least 0.1 uF decoupling per supply pin plus bulk capacitance (typically 10-100 uF tantalum) near the device. Bank voltages may differ (e.g. 3.3V or 5.0V for PCI compliance in -1 grade) provided the bank's VCCIO matches the signaling standard; mixing voltages across banks allows mixed-voltage interfacing without external level shifters.
Route all differential pairs (PCI CLK, clock inputs) with 100 ohm controlled impedance and matched lengths within tolerance per the ACEX 1K family datasheet. Place the JTAG chain (TDI, TDO, TMS, TCK) so that all four signals reach the device with matched lengths and minimal stubs; add 10K pull-ups on nCONFIG and 10K pull-down on nSTATUS as recommended. Because the TQFP-144 has 0.5mm pitch, use 4-layer PCB with continuous ground plane for signal integrity and thermal dissipation.
Do not confuse the EP1K50TC144-1N speed grade -1 with the faster -2 grade when ordering - the part markings only differ in the suffix character. Also note that VCCINT is 2.5V only; supplying 3.3V will damage the device. Configuration data must be loaded via JTAG or an EPCS-compatible serial configuration device; do not leave MSEL pins floating - tie to the appropriate logic level for the chosen configuration mode.
Estimated: the TQFP-144 package has no exposed thermal pad, so all heat dissipation flows through the lead frame and PCB copper. For high-utilization designs (>70% logic element usage at 180 MHz), provide at least 2 square inches of copper pour on the top layer connected to GND, and use thermal vias to inner ground planes to reduce junction-to-ambient thermal resistance. Avoid operating the device above 100 MHz without adequate airflow in enclosed housings.
Compliance Information
