The Intel386™ SXSA embedded microprocessor is a 5-volt, 32-bit, fully static CPU with a 16-bit external data bus and a 24-bit external address bus.
The Intel386 SXSA CPU brings the vast software library of the Intel386 architecture to embedded systems.
It provides the performance benefits of 32-bit programming with the cost savings associated with 16-bit hardware systems.
The Intel386 SXSA microprocessor is manufactured on Intel’s 0.
8-micron CHMOS V process.
This process provides high performance and low power consumption for power-sensitive applications.
Figure 3 and Figure 4 illustrate the flexibility of low power devices with respect to temperature and frequency relationships.
