TheIntel 80376, introduced January 16, 1989, was a variant of theIntel 80386SX intended forembedded systems.It differed from the 80386 in not supportingreal mode (the processor booted directly into32-bit protected mode)[1] and having no support forpaging in theMMU. The 376 was available at 16 or 20 MHzclock rates.
This processor can perform up to 3.0MIPS at 16 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 8DMA channels, 15interrupts, 4 16-bittimer/counters, DRAMrefresh controller, andwait-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-pinBQFP. The 80376 and the 82370 version also have 88-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.[2][3]
It was replaced with the much more successful80386EX from 1994, and was finally discontinued on June 15, 2001.
