EP1K50FC256-1

EP1K50FC256-1 is a legacy Altera (now Intel) EP1K family CPLD device. It is a small, fixed-architecture programmable logic device used for glue logic, simple state machines, and peripheral interfaces in embedded designs. The “50” suggests roughly 50 macrocells, and “FC256” indicates the 256-pin package variant with a specific configuration interface. The “-1” denotes the speed grade (fastest/lowest latency in the family). It includes a macrocell-based fabric, a set of I/O pins (supporting common I/O standards), and a built-in configuration interface (typically JTAG/Active Serial). Typical uses include memory interfacing, bus decoding, and control logic in compact footprints. For exact specs (macrocells, I/O count, timing, supported I/O standards, RAM blocks), consult the EP1K50FC256-1 datasheet and user guide.

EP1K50FC256-1 is an Altera (Intel) EP1K family CPLD in a FC256 package. Key features typically include:
- Logic capacity: around tens of thousands of macrocells (LUT-based, configurable logic blocks)
- Package: FC256 with up to 256 user I/O pins
- I/O banks: multiple banks with independent voltage/drive options for flexible I/O standards
- Configuration: in-system reprogrammable via JTAG; option to use external config memory (PROM)
- Interconnect: programmable interconnect and clock routing for deterministic timing
- On-chip resources: distributed RAM/ROM blocks and flip-flops within macrocells
- Performance: fast, deterministically scheduled timing suitable for glue logic and small controllers
- Power/temperature: suitable for commercial-grade operation (typical 3.3 V I/O, specified operating temp ranges)
- Debugging: JTAG boundary-scan support for programming and monitoring
Note: exact counts (e.g., macrocells, RAM blocks) and supported I/O standards can vary by revision; consult the specific datasheet for precise specs.

Pin count: 256 pins.

EP1K50FC256-1 is an Altera EPLD (FineLine BGA). Common application areas:
- Glue logic and timing/decoding for microprocessors and ASICs
- State machines and control logic
- Custom peripheral interfaces (SPI, UART, I2C, parallel I/O)
- Bus interface, protocol bridging and memory-mapped I/O
- Data routing, demux/mux and simple DSP-like processing
- Prototyping, rapid development and test benches in embedded systems
These devices are used where compact, deterministic hardware logic is needed to implement custom control, interfacing, and data-handling functions.
