GENERAL DESCRIPTION
The HX1750 is a true single chip implementation of
the MIL-STD-1750A instruction set architecture,
fabricated on Honeywell's RICMOSTM Silicon on
Insulator (SOI-IV) process. It combines a fast 16 bit
microprocessor, a 40 bit floating point processor,
counters, timers and other peripheral interface logic
– all on a single chip. Advanced architectural
features, innovative circuit design, and the high
density and performance characteristics of the SOI-
IV process enable device operation up to 40 MHz
over the full military temperature range, even after
exposure to ionizing radiation. The Soft Error Rate
(SER) is less than 1x10-11 Errors/Bit-Day in the
Adams 90% worst case environment.
The HX1750 offers a wide range of features that
provide for ease of use, versatility and minimum
external components. Simplified memory interface
and adjustable cycle times allows the use of slower,
low cost memory devices.
Most of the options in the MIL-STD-1750A standard
are implemented on the HX1750 chip as listed
below:
Discrete I/O Commands
DMA Commands
Console Interface Commands
Programmed I/O Commands
Sixteen Levels of Vectored Interrupts
I/O Maintenance Console Interface
Expanded Addressing to 1Meg with MMU
Total Dose Hardness 1x105 rad(Si)
Soft Error Rate < 1x10-9 Errors/Bit-Day- Projected
No Latchup
Low Power
IOIC Registers
Expanded Memory Addressing
Memory Block Protect
Two Interval Timers
Trigger Go Counter
Start-ROM Support

HX1750
________________________________________________________________________
Several features are incorporated into the
HX1750 to simplify the system interface,
minimize external components, reduce external
www.datasheemt4ue.mcoomry speed requirements, and ease
software development.
A separate address and data bus eliminates the
need for external PIC chip, address
demultiplexers and latches.
Fast address and data buffers provide signals
early in the cycle allowing use of slower, low
cost memories.
Enhanced Maintenance Console.
Standard memory addressing to 64K –
expanded to 1Meg with MMU.
Access Lock and Key implemented.
Simple DMA control implemented
Coprocessor supported in separate address
space.
Variable System clock – internal programmable
divider (tie Scale pin high or low) cuts the
internal bus cycle time in half.
Data, Instruction, and I/O access time
independently programmable.
Full synchronous or asynchronous operation –
programmable wait states for instructions,
data, and I/O. Asynchronous operation is
slaved to an external RDY signal.
Enhanced set of Built-In-Functions.
Enhanced Configuration Register.
Enhanced Maintenance Console – with single
step operation.
The processor executes all mandatory MIL-
STD-1750A instructions including floating
point. Interrupts, fault handling, memory
expansion, and I/O and the optional
instructions related to these operations are
also supported in accordance with MIL-STD-
1750A. All instructions are re-startable after
access faults for true demand paging
operation.
