The HI-62025 family is a fully integrated and dual redundant MIL-STD-1553 Remote Terminal interface solution which includes 1553 protocol, SRAM and dual transceivers in single 80-pin plastic PQFP and QFN package configurations. The devices are software compatible with the Data Device Corporation (DDC®) Mini-ACE®, Enhanced Mini-ACE®, Micro-ACE®, Mini-ACE® Mark3 and Total-ACE® families of MIL-STD-1553 Terminals and offer additional features such as Error-Correcting Code (ECC) SRAM. The compact single-chip monolithic design offers a significant space and cost saving over the older traditional multi-chip module approach. An improved and simplified high-performance 16-bit host interface provides faster access time to the Shared RAM, significantly reducing latency and CPU utilization. The on-chip ECC RAM provides additional protection against data corruption by automatically detecting and correcting memory errors.
