EP1K50TC144-3 개요
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines configurable logic blocks (LABs/CLBs), programmable interconnect, and I/O cells on a single die. FPGAs sit within the broader taxonomy of programmable logic devices (PLD) -> logic integrated circuits (logic IC) -> integrated circuits (IC) -> semiconductors. They enable parallel hardware execution, hardware-accelerated DSP, and rapid design iteration compared with fixed ASICs or microcontrollers. The ACEX-1K family specifically targets cost-sensitive, high-volume applications that previously required gate-array ASICs.
Key features of the EP1K50TC144-3 include a -3 speed grade, 360 LABs, 2,880 logic elements, 49,152 bits of embedded dual-port RAM, 102 maximum user I/Os, JTAG-based in-system programmability via IEEE 1149.1 boundary-scan, MultiVolt I/O supporting 2.5 V/3.3 V/5.0 V mixed-voltage interfacing, and a low-power 2.5 V core. The TQFP-144 package has a low-profile gull-wing lead format compatible with conventional SMT assembly lines.
Architecturally, the EP1K50TC144-3 uses a Look-Up Table (LUT)-based logic fabric backed by an Embedded Array Block (EAB) structure. Each EAB provides up to 4,096 bits of dual-port RAM, ROM, or specialized megafunctions such as multipliers, FIFOs, and CAM blocks. This combination delivers deterministic timing, low skew, and efficient memory utilization without external SRAM.
Typical applications include glue logic and bus interfacing in industrial controllers, low-cost DSP front-ends, communications protocol bridges (UART, SPI, I2C, parallel interfaces), legacy ASIC replacement designs, education platforms, prototyping for ASIC emulation, and small-volume production runs where mask charges are not amortizable. The wide MultiVolt I/O range makes the EP1K50TC144-3 particularly attractive when bridging 5 V MCUs to 3.3 V peripherals.
When designing with this device, note that the -3 speed grade requires careful timing closure at the upper operating frequency limit of 166.67 MHz. Use Altera's legacy MAX+PLUS II or Quartus II design software for synthesis, fitting, place-and-route, and programming file generation. The 144-TQFP package has limited thermal dissipation; consult the device handbook for thermal design guidelines if operating at industrial temperature extremes.

일반적인 애플리케이션
EP1K50TC144-3 적합 용도: 6 애플리케이션s: Industrial Control Glue Logic and Bus Interfacing, Legacy ASIC Replacement and Bridge Chip, Communications Protocol Bridging, Education Platform and FPGA Prototyping, Low-Volume Production and ASIC Emulation, DSP Front-End and Custom Filter Implementation.
Industrial Control Glue Logic and Bus Interfacing
The EP1K50TC144-3 is well-suited for industrial control glue logic and bus-bridging applications where its 2,880 logic elements, 360 LABs, and 102 user I/Os provide ample capacity for parallel protocol converters and signal-conditioning state machines. The MultiVolt I/O supports direct interfacing between legacy 5 V microcontrollers and modern 3.3 V peripherals without external level shifters. Designers typically place the EP1K50TC144-3 between a 5 V MCU bus and a 3.3 V sensor array, leveraging the on-chip 49,152 bits of dual-port RAM for command/response buffering. Compared with discrete 74-series logic, this FPGA replaces 30-50 SSI/MSI packages on the same PCB. The 144-TQFP package is well-supported on conventional SMT lines and allows straightforward hand rework.
추천
Legacy ASIC Replacement and Bridge Chip
The EP1K50TC144-3 is frequently deployed as a drop-in replacement for obsolete masked ASICs and discontinued gate-array designs, particularly in industrial and instrumentation equipment with 5-10 year field lifetimes. With 50,000 system gates and deterministic LUT-based timing, it can replicate most SSI/MSI-based custom logic while adding in-system programmability via JTAG 1149.1 boundary-scan. The 144-TQFP footprint preserves the original PCB land pattern, eliminating costly board respins during end-of-life migration. Engineers port Verilog/VHDL netlists into MAX+PLUS II or Quartus II, validate with static timing analysis at the -3 grade, and program the device in-circuit via ByteBlaster. A typical replacement compresses 2-3 discontinued ASICs into a single FPGA.
추천
Communications Protocol Bridging
For communications protocol bridging, the EP1K50TC144-3 delivers enough logic capacity to implement UART, SPI, I2C, and parallel-interface bridges concurrently, plus 49,152 bits of dual-port RAM for FIFO buffering of asynchronous data streams. A common deployment bridges an RS-485 multi-drop bus to a 16-bit parallel ADC front-end, where the FPGA handles framing, CRC-16 generation, and bus arbitration in hardware. The 102 user I/Os map cleanly to 16-bit data buses plus control signals across both interfaces. MultiVolt I/O eliminates level-shifters when bridging 5 V and 3.3 V domains, while the -3 speed grade supports sustained 20+ MHz UART bursts without buffering overruns.
추천
Education Platform and FPGA Prototyping
The EP1K50TC144-3 is commonly found on university FPGA laboratory boards and embedded-systems training kits because its 50K-gate capacity is sufficient to demonstrate full processor cores, custom peripherals, and DSP pipelines, while its 144-TQFP package is easy to handle in lab environments. Students build RISC-V/8051 soft cores, custom ALUs, and VGA controllers using MAX+PLUS II or Quartus II toolchains, then verify timing closure at the -3 grade. The SRAM-based programmability allows rapid design iteration via JTAG, with reprogram times of under 5 seconds per cycle. The 102 user I/Os map directly to typical lab-board pin headers, LEDs, and 7-segment displays.
추천
Low-Volume Production and ASIC Emulation
The EP1K50TC144-3 is ideal for low-volume production runs and ASIC emulation because it eliminates the high NRE cost of masked ASICs while delivering deterministic LUT-based timing. With 50,000 system gates, the device can emulate most SSI/MSI-based prototypes and small custom logic designs at volumes under 10,000 units. The 2.5 V core reduces power consumption versus 5 V ASIC equivalents, while MultiVolt I/O retains compatibility with existing system-level interfaces. Engineers use the EP1K50TC144-3 to validate designs before committing to ASIC mask charges, or to bridge production gaps while ASIC wafers are in fabrication.
추천
DSP Front-End and Custom Filter Implementation
The EP1K50TC144-3 supports low-cost DSP front-end designs such as FIR filters, FFT pre-processors, and digital down-converters by leveraging its 360 LABs, 2,880 LEs, and 49,152 bits of embedded dual-port RAM. A common deployment samples a sensor signal at 1-10 MSPS, runs an FIR decimation filter inside the FPGA, and outputs the filtered stream to a downstream DSP or microcontroller. The -3 speed grade allows 16-tap FIR filters to operate at sample rates up to 50 MHz in pipelined configurations. Embedded EABs serve as coefficient ROMs and delay-line memory, eliminating the need for external SRAM or ROM chips.

설계 노트
The EP1K50TC144-3 requires a clean 2.5 V core supply (VCCINT) plus a MultiVolt VCCIO supply (typically 2.5 V, 3.3 V, or 5.0 V) for the I/O banks. Decouple each VCCINT pin with a 0.1 μF ceramic plus a 10 μF tantalum bulk capacitor placed within 5 mm of the package. Each VCCIO bank has separate supply pins that must be tied to the desired I/O voltage; do NOT leave VCCIO floating - the device will not configure properly without I/O bank power.
Estimated: at 166.67 MHz toggling frequency with 50% logic utilization, the EP1K50TC144-3 dissipates approximately 0.5-1.0 W internally. The 144-TQFP package (theta_JA ~35 C/W on a standard 4-layer JEDEC board) gives a junction temperature rise of 18-35 C above ambient. For commercial-grade parts in lab environments this is acceptable, but at industrial temperatures (-40C to +85C) confirm with worst-case static power models in the Quartus II power analyzer.
The EP1K50TC144-3 is SRAM-based and loses its configuration on power-down; you must either use an external configuration EPROM (Altera EPC2 or compatible) or instantiate the device with a hard-wired controller on every board revision. The JTAG chain order matters when multiple devices share TDI/TDO - verify the BSDL file against your schematic. Note that Quartus II dropped ACEX-1K device support after v9.1, so archive the legacy toolchain or use MAX+PLUS II.
Route all four I/O bank supplies (VCCIO_1 through VCCIO_4) as separate power islands if you intend to mix 2.5 V, 3.3 V, and 5 V I/O standards - sharing one VCCIO rail across banks limits MultiVolt flexibility. Place the EP1K50TC144-3 in the centre of the PCB with short trace lengths to the configuration EPROM and JTAG header. Maintain 50 ohm controlled impedance on clock and high-speed I/O traces, and keep global clock input pins (GCLK) routed on inner layers with continuous ground reference planes beneath.
