Space Electronic’s 80386DXRP (RP for RAD-PAK®) high performance 32-
bit microprocessor features a typical 100krad (Si) total dose tolerance;
dependent upon orbit. It is designed for very high performance and
multitasking operating systems. The integrated memory management and
protection architecture support operating systems. The 80386DXRP allows
simultaneous running of multiple operations. In addition, the 80386DXRP
is capable of execution at sustained rates of between 3 and 4 million
instructions per second. It offers new testability and debugging features,
include a self-test and direct access to the page translation cache. The
patented radiation hardened RAD-PAK® technology incorporates radiation
shielding in the microcircuit package. Capable of surviving in space
environment, the 80386DXRP is ideal for satellite, spacecraft, and space probe
missions. It is available with packaging and screening up to Class S.

NOTE:
1/ Float condition occurs when maximum output current becomes less than ILO in magnitude.
2/ These inputs are allowed to be asynchronous to CLK2. The setup and hold specifications are given for testing purposes, to assure recognition within a specific CLK2 period.
3/ Guaranteed by design if not tested.
