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. Key performance-enhancing 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-word memory block protection

capability,

The MAS281 is offered in several screening grades which

are described in this document. For availability of speed

grades, please contact Dynex Semiconductor.
