General Description Aeroflex’s CT2553 Advanced Integrated Mux (AIM) Hybrid is a plete 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, plete 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 bined 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°C to +125°C temperature range. Available screened to MIL-STD883, the CT2553 is ideal for demanding military and industrial microprocessor to 1553 interface applications. See...
