Radiation Hardened Real Time Express™
Microcontroller
The HS-RTX2010RH is a radiation-hardened 16-bit
microcontroller with on-chip timers, an interrupt controller, a
multiply-accumulator, and a barrel shifter. It is particularly
well suited for space craft environments where very high
speed control tasks which require arithmetically intensive
calculations, including floating point math to be performed in
hostile space radiation environments.
This processor incorporates two 256-word stacks with
multitasking capabilities, including configurable stack
partitioning and over/underflow control.
Instruction execution times of one or two machine cycles are
achieved by utilizing a stack oriented, multiple bus
architecture. The high performance ASIC Bus, which is
unique to the RTX product, provides for extension of the
microcontroller architecture using off-chip hardware and
application specific I/O devices.
RTX Microcontrollers support the C and Forth programming
languages. The advantages of this product are further
enhanced through third party hardware and software support.
Combined, these features make the HS-RTX2010RH an
extremely powerful processor serving numerous
applications in high performance space systems. The
HS-RTX2010RH has been designed for harsh space
radiation environments and features outstanding Single
Event Upset (SEU) resistance and excellent total dose
response.

BOOT: A HIGH on this pin indicates that Boot Memory is being accessed. This pin can be set or reset by accessing
bit 3 of the Configuration Register.
MEMORY READ/WRITE: A LOW on this pin indicates that a Memory Write operation is in progress.
UPPER DATA SELECT: A HIGH on this pin indicates that the high byte of memory (MD15-MD08) is being
accessed.
LOWER DATA SELECT: A HIGH on this pin indicates that the low byte of memory (MD07-MD00) is being
accessed.
ASIC I/O: A LOW on this pin indicates that an ASIC Bus operation is in progress.
ASIC READ/WRITE: A LOW on this pin indicates that an ASIC Bus Write operation is in progress.
PROCESSOR CLOCK: Runs at half the frequency of ICLK. All processor cycles begin on the rising edge of PCLK.
Held low extra cycles when WAIT is asserted.
TIMING CLOCK: Same frequency and phase as PCLK but continues running during Wait cycles.
INTERRUPT ACKNOWLEDGE: A HIGH on this pin indicates that an Interrupt Acknowledge cycle is in progress.

WAIT: A HIGH on this pin causes PCLK to be held LOW and the current cycle to be extended.
INPUT CLOCK: Internally divided by 2 to generate all on-chip timing (CMOS input levels).
A HIGH level on this pin resets the RTX. Must be held high for at least 4 rising edges of ICLK plus 12 ICLK cycle
setup and hold times.

edge of PCLK. See Timing Diagrams for detail.
EXTERNAL INTERRUPTS 5, 4, 3: Dual purpose inputs; active HIGH level-sensitive Interrupt Controller inputs;
active HIGH edge-sensitive Timer/Counter inputs. As interrupt inputs, they are sampled on the rising edge of PCLK.
See Timing Diagrams for detail.
NON-MASKABLE INTERRUPT: Active HIGH edge-sensitive Interrupt Controller input capable of interrupting any
processor cycle when NMI is set to Mode 0. See the Interrupt Suppression and Interrupt Controller Sections.
INTERRUPT SUPPRESS: A HIGH on this pin inhibits all maskable interrupts, internal and external.
