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]] (the processor booted directly into [[protected mode|32-bit protected mode]])<ref>Lewnes, Ann, "Intel's 80960 & 80376 Standouts in the 32-Bit Crowd", Intel Corporation, Microcomputer Solutions, July/August 1988, page 2</ref> and having no support for [[paging]] in the [[Memory management unit|MMU]]. The 376 was available at 16 or 20&nbsp;MHz [[clock rate]]s.

This processor can perform up to 3.0 [[Instructions per second#Millions of instructions per second (MIPS)|MIPS]] at 16&nbsp;MHz speed.  It offers from 70 to 80 percent of the performance with 80386 at the same clock speed.  This processor has external 16-bit bus with internal 32-bit bus.  The Intel 82370 chipset which contains 8 [[Direct memory access|DMA]] channels, 15 [[interrupt]]s, 4 16-bit [[Programmable interval timer|timer/counters]], DRAM [[Memory refresh|refresh controller]], and [[Wait state|wait-state]] generator which it is closely coupled with this processor, but it is software compatible to Intel 82380 chipset.  Both devices are packaged with 100-pin [[BQFP]].  The 80376 and the 82370 version have also have 88-[[Pin grid array|PGA]] and 132-PGA package as well respectively.  The plastic version of 80376 were US$99 and 82370 were US$57 in quantities of 100 respectively.<ref>Ormsby, Jon, Editor, "New Product Focus: Components: Intel Enters The World Of 32-Bit Embedded Control", Intel Corporation, Microcomputer Solutions, May/June 1988, page 9</ref><ref>Lewnes, Ann, "Intel's 80960 & 80376 Standouts in the 32-Bit Crowd", Intel Corporation, Microcomputer Solutions, July/August 1988, page 2</ref>

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