The Intel 80376, introduced January 16, 1989, was a variant of the
Intel 80386SX intended for
embedded systems.
It differed from the 80386 in not supporting
real mode
Real mode, also called real address mode, is an operating mode of all x86-compatible CPUs. The mode gets its name from the fact that addresses in real mode always correspond to real locations in memory. Real mode is characterized by a 20-bit seg ...

) and having no support for
paging in the
MMU. The 376 was available at 16 or 20 MHz
clock rates.
This processor can perform up to 3.0
MIPS at 16 MHz speed. The Intel 82370 chipset which contains 8

It was replaced with the much more successful
80386EX from 1994, and was finally discontinued on June 15, 2001.
