General Description
Aeroflex鈥檚 CT2553 Advanced Integrated Mux (AIM) Hybrid is a complete MIL-STD-1553 Bus
Controller (BC), Remote Terminal Unit (RTU), and Bus Monitor (MT) device. Packaged in a single
78 pin DIP package, the CT2553 contains dual low-power transceivers, complete BC/RTU/MT
protocol logic, a MIL-STD-1553-to-host interface unit and an 8K x 16 RAM.
Using an industry standard dual transceiver and standard status and control signals, the CT2553
simplifies system integration at both the MIL-STD-1553 and host processor interface levels.
All 1553 operations are controlled through the CPU access to the shared 8K x 16 RAM. To ensure
maximum design flexibility, memory control lines are provided for attaching external RAM to the
CT2553 Address and Data Buses and for disabling internal memory; the total combined memory
space can be expanded to 64K x16. All 1553 transfers are entirely memory-mapped; thus the CPU
interface requires minimal hardware and/or software support.
The CT2553 operates over the full military -55擄C to +125擄C temperature range. Available screened
to MIL-STD883, the CT2553 is ideal for demanding military and industrial microprocessor to 1553
interface applications.
See "Ordering Information" (last sheet) for CT2554, CT2555 & CT2556.
