[edit] Characteristics

• Introduced August 1994
• Variant of 80386SX intended for embedded systems
• Static core, i.e. may run as slowly (and thus, power efficiently) as desired, down to full halt
• On-chip peripherals:
  • clock and power mgmt
  • timers/counters
  • watchdog timer
  • serial I/O units (sync and async) and parallel I/O
  • DMA
  • RAM refresh
  • JTAG test logic
• Significantly more successful than the 80376
• Used aboard several orbiting satellites and microsatellites
• Used in NASA's FlightLinux project
