EP1K50FC484-1N 概要
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.

主な用途
EP1K50FC484-1N の用途: 6 件s: Communications Infrastructure Glue Logic, Industrial Control & Instrumentation, PCI / Local-Bus Bridging, Test & Measurement Backplanes, Low-Volume Custom DSP Pre/Post-Processing, Legacy Peripheral & Protocol-Conversion Cards.
Communications Infrastructure Glue Logic
The EP1K50FC484-1N's 50K gates and 249 user I/O in a 484-FBGA package make it a strong fit for telecom glue-logic cards that bridge standard buses and protocol converters. Its 250 MHz internal clock and PCI-compatible I/O let it absorb protocol adaptation between legacy TDM backplanes and packet-based fabrics without external bus switches. The 12 EABs (40,960 bits of dual-port RAM) handle small cell buffers and lookup tables in place of an external SRAM, reducing BOM cost. Compared with a CPLD, the EP1K50 absorbs wider parallel buses in one device.
おすすめ
Industrial Control & Instrumentation
With 249 I/O pins and multi-standard I/O support (3.3 V LVTTL/LVCMOS, PCI, GTL+), the EP1K50FC484-1N is well-suited to industrial controllers that must interface parallel ADC/DAC banks, motor-control PWMs, and field-bus bridges in a single device. The 2.5 V core is tolerant of industrial 24 V supply rails after step-down, and the JTAG boundary-scan interface simplifies in-system programming on the production line. The device is commercial-grade (0 °C to +70 °C); for harsher industrial thermal ranges, select the I-temp variant or migrate to Cyclone IV.
おすすめ
PCI / Local-Bus Bridging
The EP1K50FC484-1N's PCI-compatible I/O pins and 50K-gate capacity let it act as a transparent bridge between a 32-bit/33 MHz PCI bus and a proprietary peripheral bus, eliminating the need for an expensive PCI bridge ASIC. Its 12 EABs (40,960 bits) can implement small FIFO buffers in dual-port mode, smoothing burst transfers across clock domains. The 484-FBGA package exposes enough user I/O to break out both 32-bit PCI and a 32-bit local bus simultaneously. Quartus IP cores provide ready-made PCI target controllers.
おすすめ
Test & Measurement Backplanes
The EP1K50FC484-1N serves well in test-and-measurement backplanes where multiple parallel data streams (LVTTL/LVCMOS) must be multiplexed, framed, and forwarded to a host processor. The 360 LABs and 12 EABs support pattern generation, error counters, and small DSP pre-processing pipelines up to 250 MHz. The 484-FBGA package enables compact PCB layouts with controlled-impedance routing for high-speed LVDS-style signals. JTAG scan chains enable board-level boundary-scan test integration on production testers.
おすすめ
Low-Volume Custom DSP Pre/Post-Processing
For low-volume designs requiring custom DSP pipelines (FIR filters, FFT pre-processing, codec rate conversion), the EP1K50FC484-1N delivers 50K gates and 12 EABs of memory at a fraction of ASIC NRE cost. The 250 MHz internal clock supports video-rate DSP at common pixel clock frequencies. Compared with a discrete DSP processor, the FPGA allows bit-width customization and parallel datapaths. Quartus DSP IP and Megafunctions simplify filter and FFT instantiation.
おすすめ
Legacy Peripheral & Protocol-Conversion Cards
The EP1K50FC484-1N is a typical solution for legacy peripheral cards that must translate between obsolete parallel protocols (VME, ISA, PC/104) and modern serial interfaces. Its wide I/O count (249 pins) accommodates several legacy buses simultaneously, and its EAB-based dual-port RAM acts as a rate-matching buffer between asynchronous domains. For long-life-cycle industrial and defense systems that must remain in production for decades, the EP1K50FC484-1N's mature tooling (Quartus II) and broad second-source availability remain an advantage.

設計ノート
The EP1K50FC484-1N requires a 2.5 V VCCINT core supply separate from VCCIO I/O bank supplies. Estimate Iccint at approximately 5-15 mA per MHz of internal toggle rate plus static EAB/IO contribution; use a low-noise LDO such as an LT3021-2.5 or TPS7A45 followed by a 22 µF + 0.1 µF ceramic decoupling network. I/O bank VCCIO must match the chosen I/O standard (3.3 V LVTTL, 2.5 V LVCMOS, 3.3 V PCI, etc.).
The 484-FBGA package requires multilayer PCB escape routing. Use microvias (laser-drilled, 6 mil pad) on at least 4 routing layers if possible, with the top layer dedicated to fan-out and inner layers for signal routing. Keep all decoupling capacitors within 100 mils of their respective supply balls and stitch GND vias on every BGA corner ball. Controlled-impedance traces (50 Ω single-ended) are mandatory for clocks and high-speed I/O.
ACEX-1K FPGAs use SRAM configuration cells, so they must reconfigure on every power-up. Provide a configuration source: a serial configuration PROM (EPC2LC20 / EPC4 / EPC8) in PS or AS mode, JTAG, or a microcontroller driving DCLK/DATA. Failure to populate the configuration source results in a non-functional board. JTAG chain integrity (TCK, TMS, TDI, TDO) must be verified with the Quartus programmer before board bring-up.
The 484-FBGA package has a θJA of approximately 15-20 °C/W (with proper PCB thermal design). For typical designs running at moderate toggle rates, junction temperature rise above ambient is under 10 °C. For high-utilization designs (>80% LE usage, high EAB bandwidth), verify thermal performance in the Quartus PowerPlay tool and add thermal vias under the BGA if needed.
