EPF10K10LC84-4

The EPF10K10LC84-4 is a member of the Altera FLEX 10K family of programmable logic devices (PLDs). It features 10,000 usable gates, 84-pin PLCC packaging, and operates at -4 speed grade, indicating moderate performance.
Key features:
- Embedded Programmable Logic: Combines logic elements (LEs) and embedded array blocks (EABs) for flexible design.
- Reconfigurable: Supports in-system programmability via SRAM-based configuration.
- I/O Flexibility: 84-pin layout with multiple I/O standards.
- Typical Applications: Used in prototyping, digital signal processing, and embedded systems.
The -4 suffix denotes its speed grade, with lower numbers indicating faster performance. It requires external configuration memory (e.g., EEPROM) for operation.
For detailed specs, refer to Altera’s (now Intel) FLEX 10K datasheet.

The EPF10K10LC84-4 is an older Altera (now Intel) FPGA from the FLEX 10K family. Direct equivalents are scarce due to its age, but modern alternatives include:
- Intel (Altera) MAX 10 series (e.g., 10M02, 10M04)
- Lattice Semiconductor ICE40 (e.g., ICE40LP1K)
- Xilinx Spartan-3/6 (e.g., XC3S50, XC6SLX9)
These offer similar or better logic capacity and features. Check pin compatibility and design requirements before substitution.

The EPF10K10LC84-4 is an Altera (now Intel) FLEX 10K series FPGA.
- Pin Count: 84 (PLCC package)
- Key Functions:
- Logic Elements: ~10,000 gates (typical)
- I/O Pins: 59 (bidirectional, 3.3V/5V tolerant)
- Embedded RAM: 6 EABs (Embedded Array Blocks)
- Speed Grade: -4 (4ns pin-to-pin delay)
- Configuration: JTAG, passive serial/parallel
Designed for general-purpose logic, prototyping, and mid-range applications.

The EPF10K10LC84-4 is a field-programmable gate array (FPGA) manufactured by Altera Corporation, now part of Intel after its acquisition in 2015.
Altera was a leading company in programmable logic devices, specializing in FPGAs, CPLDs, and related development tools. The EPF10K10LC84-4 belongs to Altera's FLEX 10K family, a popular FPGA series in the 1990s and early 2000s.
Intel integrated Altera into its Programmable Solutions Group (PSG), continuing FPGA production under the Intel brand while retaining Altera’s legacy product lines.

The EPF10K10LC84-4 is an FPGA from Altera's FLEX 10K family. It comes in an 84-pin PLCC (Plastic Leaded Chip Carrier) package. This surface-mount package is suitable for prototyping and embedded applications, offering a compact form factor with leads on all four sides. The "-4" suffix indicates a speed grade of 4ns.
