The Acromag IP-1K100-0024 is a user-programmable FPGA module built around the Altera EP1K100 device for embedded custom logic implementation and high-speed data processing. This Industry Pack (IP) module enables adaptive computing through in-system FPGA configuration via JTAG or IP bus, with a pre-programmed CPLD handling power-up initialization. Engineers develop applications in VHDL using Altera MAX+PLUS® II or Quartus® tools, downloading directly to the FPGA through the IP bus.
