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.
