Description

Aeroflex CT2566 MIL-STD-1553 to Microprocessor Interface Unit simplifies the CPU to 1553 Data

Bus interface. The CT2566 provides an interface by using RAM allowing the CPU to transmit or

receive 1553 traffic simply by accessing the memory. All 1553 message transfers are entirely

memory or I/O mapped. The CT2566 supports 1553 interface devices such as Aeroflex's CT2512

dual RT or the CT2565 dual BC, RT, and MT. The CT2566 operates over the full military -55°C to

+125°C temperature range.
