Overview

Description

EP1K100FI256-2 is an Altera (now Intel) EP1K family EPLD (Erasable Programmable Logic Device). It’s a low‑density, single-chip programmable logic device with about 1K logic elements, housed in a 256‑pin FineLine package (FI256) and rated speed grade -2. The device provides configurable logic blocks, flip‑flops, and small distributed RAM, plus I/O banks for glue logic, simple state machines, decoders, and control logic. It’s programmed with legacy Altera tools (e.g., MAX+PLUS II or early Quartus) and reconfigured via a programming cable or in-system interface (JTAG/AS). EP1K parts are used for compact, cost‑sensitive logic tasks where larger FPGAs are unnecessary. Today they’re largely superseded by newer Intel/Altera families (Cyclone/MAX II), but can still be suitable for small, fixed-function logic in older designs.

Features

EP1K100FI256-2 features (concise):
- 100K equivalent logic elements (LEs)
- 256-pin FineLine package (F256)
- -2 speed grade
- 3.3V single-supply operation
- In-system programmable (JTAG or external config)
- LUT-based configurable logic blocks with flip-flops
- On-chip distributed RAM blocks and shift registers
- Flexible programmable interconnect and I/O blocks
- Large I/O count in package (hundreds of I/Os)
- JTAG boundary-scan for test and programming
Note: exact I/O counts and RAM sizes vary by device configuration.

Pinout

- Pin count: 256 pins (FI256 package)
- Function: Altera EP1K100 series EPLD/FPGA—an early programmable logic device used to implement user logic with programmable logic elements and I/O (not a fixed-function microcontroller).

Manufacturer

Manufacturer: Altera Corporation (now part of Intel).
What kind of company: A semiconductor company that designs and manufactures programmable logic devices, including FPGAs and CPLDs, along with related design tools and intellectual property.

Application

Possible application areas for EP1K100FI256-2:
- Digital logic fabric and DSP acceleration for custom algorithms
- Communications and networking hardware (protocol engines, line interfaces)
- Data acquisition, signal conditioning and instrumentation
- Industrial automation and control systems
- Embedded system peripherals and custom I/O interfaces
- Image/video processing pipelines and capture/processing tasks
- Prototyping, evaluation boards, and educational/research lab use
These FPGA-based solutions are suited for cost-conscious, medium-complexity designs requiring flexible hardware acceleration and custom interfaces.

Package

FineLine BGA (FBGA) package, 256-ball.
