EP1K50FC484-1N Ringkasan

The Intel (formerly Altera) EP1K50FC484-1N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs), delivering approximately 50,000 system gates, 2,880 logic elements, and 40,960 bits of embedded SRAM in a 484-ball FineLine BGA (FBGA) package. It is built on a 0.22 µm CMOS process, operates from a 2.5 V core supply, and supports 249 programmable I/O pins with up to 250 MHz internal performance. The "-1N" suffix indicates the commercial speed grade and lead-free / RoHS-compliant package option.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that sits between a microcontroller and a custom ASIC in the semiconductor hierarchy: ASIC → FPGA → microcontroller → general-purpose processor. FPGAs integrate configurable logic blocks (LEs), programmable interconnect, and on-chip memory so engineers can implement arbitrary digital logic, DSP pipelines, glue logic, and bus interfaces without a custom mask set. The ACEX-1K family was the first Altera family to embed dedicated array blocks (EABs) for memory or arithmetic functions, and it targets glue-logic, bus-bridging, and low-to-mid volume custom logic designs.

Key features of the EP1K50FC484-1N include 360 Logic Array Blocks (LABs), 12 Embedded Array Blocks (EABs) providing 40,960 RAM bits, multi-standard I/O support (LVTTL, LVCMOS, PCI, GTL+, SSTL-2), in-system programmability via the JTAG-compliant IEEE Std. 1149.1 interface, and 4 dedicated clock inputs with up to 6 global clock networks. The 484-FBGA package exposes 249 user I/O, giving designers ample headroom for parallel buses and memory interfaces while fitting into a surface-mount footprint.

From an architectural standpoint, each Logic Element in ACEX-1K contains a 4-input look-up table (LUT), a programmable register, and a carry chain for arithmetic. The EABs can be configured as 4,096-bit RAM or ROM blocks, allowing efficient implementation of FIFOs, lookup tables, and small algorithmic coefficient stores. The device is configured using SRAM-based configuration cells, so it loads its bitstream on every power-up from a serial PROM, JTAG, or controller.

Typical applications include communications infrastructure glue logic, peripheral-bus bridging (e.g., PCI to local bus), industrial control and instrumentation, low-volume custom DSP pre/post-processing, and test-and-measurement backplanes. The wide I/O count also suits multi-channel data-acquisition front ends and protocol-conversion cards where multiple asynchronous interfaces must be absorbed in a single device.

When designing with the EP1K50FC484-1N, plan for the 2.5 V VCCINT core rail (separate from VCCIO for I/O banks), provide a configuration source (serial configuration PROM or JTAG), and respect the FBGA-484 routing rules (escape routing on multiple layers, microvia stack if possible). The device is commercial temperature grade (0 °C to +70 °C); industrial or military temperature grades carry the "I" or "MIL" speed-grade suffix.
