EPF10K20TI144-4N

The EPF10K20TI144-4N is a member of the Altera FLEX 10K family of programmable logic devices (PLDs). It features 20,000 logic gates, 1,440 logic elements (LEs), and 144 pins in a TQFP (Thin Quad Flat Pack) package.
Key specifications:
- 4ns pin-to-pin delay (speed grade -4N)
- 5V operating voltage
- In-system programmable (ISP) via JTAG
- Embedded memory (EABs) for flexible storage
Applications include digital signal processing (DSP), communications, and embedded control systems. The FLEX 10K architecture combines look-up tables (LUTs) and embedded array blocks (EABs), making it suitable for both logic and memory-intensive designs.
This device is now considered obsolete, with modern alternatives like Intel (formerly Altera) MAX 10 or Cyclone FPGAs recommended for new designs.
For legacy support, refer to Altera’s archived documentation.

The EPF10K20TI144-4N is an older Altera (now Intel) FPGA. Direct equivalents include:
- EPF10K20TI144-3N (slower speed grade)
- EPF10K20TI144-1N (faster speed grade)
- EP1K20TI144-4N (similar Cyclone family alternative)
Modern replacements:
- Intel MAX 10 (10M08, 10M16)
- Lattice ECP5 (for low-power alternatives)
