MAS281 - MIL-STD-1750A Microprocessor

General Description

of these

Key Features

  • include a parallel multiplier/accumulator, 32-bit barrel shifter, instruction pre-fetch queue, and multiport register file. Additional features include a comprehensive Built-ln-Test (BIT), interval timers A and B, trigger-go counter, and Start-Up ROM interface. In accordance with MIL-STD-1750A, the MAS281 supports a 64K-word address space. An optional BMA31751 Memory Management Unit/Block Protect Unit (MMU(BPU)) chip may be added externally to expand this address space to 1M-words or add a 1K-wo.

MAS281 MAS281 MIL-STD-1750A Microprocessor Replaces June 1999 version, DS3563-4.0 DS3563-5.0 January 2000 The MAS281 Microprocessor is a MIL-STD-1750A (Notice 1), 16-bit Central Processing Unit (CPU). It consists of three CMOS/SOS large-scale integration (LSI) chips: the MA17501 Execution Unit (EU), the MA17502 Control Unit (CU), and the MA17503 Interrupt Unit (IU). These three units can be mounted on, and interconnected within a 64-pin ceramic substrate. The microprocessor is also available as a 3-chip set without the ceramic substrate (see ordering information on page 55). The MAS281 is optimised for real-time l/O and arithmetic intensive operations.
