BUS-61553 Datasheet | Data Device

DESCRIPTION S FEATURES a - Fully Intergrated Terminal at Including: .D - Dual Transceiver w - BC/RT/MT Protocol w - Memory Management Unit w - Processor lnterface Logic DDC’s BUS-61553 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 BUS-61553 contains dual low-power transceivers, plete BC/RT/MT protocol logic, a MIL-STD-1553-to-host interface unit and 8K x 16 RAM. Using an industry standard dual transceiver and standard status and control signals, the BUS-61553 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 BUS-25679 8 1 DATA BUS A 2 4 3 TRANSFORMER A BUS-25679 8 DATA BUS B 4 1 2 3 m o .c U 4 t e e h S a t a .D w w w - 8K x 16 RAM The BUS-61553 operates over the full military -55°C to +125°C temperature range. Available screened to MIL-PRF-38534, the BUS-61553 is ideal for demanding military and industrial microprocessor-to-1553 interface applications. shared 8K x 16 RAM. To ensure maximum design flexibility, memory control lines are provided for attaching external RAM to the BUS-61553 address and data buses and for disabling internal memory; the total bined memory space can be expanded to 64K x 16. All 1553 transfers are entirely memory-mapped; thus the CPU interface requires minimal hardware and/or software support. - CMOS and Bipolar Technologies - Internal Interrupt Status and Time Tag Registers - High Reliability - 883B Processing Available TRANSCEIVER A TX INH TX CLOCK IN CHANNEL A ENCODER/ DECODER MEMORY TIMING CPU TIMING MSTRCLR SELECT STRBD READYD RD/WR MEM/REG EXTEN EXTLD INT 768 µs TIME OUT PROTOCOL CONTROLLER CONTENTION RESOLVER INTERRUPT GENERATOR TX INH TX TRANSFORMER B RX RX TRANSCEIVER B © 1987, 1999 Data Device Corporation m o .c U 4 t e e h S a t a FIGURE 1.
