EPF10K20RI208-4N

The EPF10K20RI208-4N is a member of the Altera FLEX 10K family of programmable logic devices (PLDs). It features 20,000 gates, making it suitable for medium-complexity digital designs. Key specifications include:
- 208-pin RQFP package (Plastic Quad Flat Pack)
- 4ns pin-to-pin delay (high-speed performance)
- Embedded programmable logic with EEPROM-based configuration
- Flexible I/O and support for multiple voltage levels
Designed for applications like telecommunications, industrial control, and embedded systems, it offers reconfigurability and integration benefits. The "-4N" suffix indicates its speed grade (4ns).
For detailed usage, refer to Altera’s (now Intel) datasheets and development tools like Quartus II or legacy MAX+PLUS II.

The EPF10K20RI208-4N is an older Altera (now Intel) FLEX 10K FPGA. Direct equivalents are scarce due to its age, but modern alternatives include:
- Intel (Altera) MAX 10 series (e.g., 10M08, 10M16)
- Lattice Semiconductor iCE40 or ECP5 (for low-cost FPGAs)
- Xilinx (AMD) Spartan-6 or Artix-7 (for similar logic capacity)
Check pin compatibility and features before substitution. For legacy support, consider refurbished or NOS (new old stock) suppliers.

The EPF10K20RI208-4N is a field-programmable gate array (FPGA) manufactured by Intel (formerly Altera).
Intel acquired Altera in 2015, integrating its FPGA technology into its product lineup. Altera was a leading FPGA company, known for its programmable logic devices used in telecommunications, industrial automation, and consumer electronics.
Intel now produces Altera-branded FPGAs, including the EPF10K20RI208-4N, which belongs to the FLEX 10K family. These devices are used for digital logic design, prototyping, and embedded applications.
Intel is a global semiconductor leader, specializing in CPUs, GPUs, and programmable solutions like FPGAs.

The EPF10K20RI208-4N is an FPGA from Intel (formerly Altera) in the FLEX 10K family. It comes in a 208-pin RQFP (Plastic Quad Flat Pack) package. The "RI208-4N" suffix indicates the package type (RQFP), pin count (208), and speed grade (-4N). This package is surface-mountable, suitable for high-density PCB designs.
