The Tek Microsystems FP-DFLEX-10K is an Industry Pack (IP) module that integrates Altera FLEX 10K programmable logic for custom hardware-level processing in industrial automation, embedded systems, and laboratory test environments. The module delivers flexible, reconfigurable I/O with selectable EIA-485 or TTL operation and programmable termination control, enabling rapid deployment of pattern generators, pulse generators, edge detection circuits, and custom serial/parallel interfaces without requiring external configuration hardware or software.
Technical Specifications
• Core Logic: Altera FLEX 10K embedded programmable logic family
• I/O Density: Up to 24 EIA-485 interfaces or 48 TTL interfaces, software-selectable
• Signal Architecture: 24 external signal pairs (A[1:24], B[1:24]) with independent DE (Driver Enable), DO (Driver Output), and RI (Receiver Input) control per pair
• Serial Control: S485 and nS485 signals for each group of four A/B pairs
• EIA-485 Transceiver: Maxim MAX1484
• Programmable Termination: Maxim MAX335 switches between A/B pairs, 100–150 Ohms on-resistance, controlled via TR_CLK, TR_DATA, and TR_nCS serial interface
