Acromag IP-1K110-0024 Reconfigurable FPGA IndustryPack Module

The Acromag IP-1K110-0024 is a reconfigurable FPGA IndustryPack module that implements custom logic and flexible I/O control in industrial systems. Built around an Altera EP1K100 FPGA, it allows engineers to develop and deploy their own instruction sets directly into the device via the IP bus. The module manages up to 48 TTL or 24 differential RS485 I/O signals - or any combination - with independent directional control.

An internal CPLD acts as bus controller during initialization and configuration, then relinquishes control to the user-programmed FPGA. Onboard resources include 64K × 16 static RAM, a programmable interval timer, and a PLL-based clock synthesizer with external LVTTL clock input capability.
