1.1 INTRODUCTION
The Signetics 8X300 Microcontroller is a high-speed 8-bit bipolar
microprocessor, fabricated using Schottky technology. The device is
capable of executing (fetch, decode and execute) a 16-bit
instruction in one machine cycle (a minimum of 250 nanoseconds),
with a maximum power consumption of less than 2.5 watts. The
8X300 architecture and instruction set are designed to provide a
high data throughput with bit-oriented, rather than word-oriented
operations. This allows the designer a considerable degree of
flexibility in control applications. Under program control, the
microprocessor is able to select and test individual bits or groups of
bits, make calculations and decisions based upon the selected data,
and issue appropriate commands to the system.
Because of its high speed, the 8X300 is able to perform, through
software, many operations that would otherwise have to be
performed by additional hardware. The resultant lower parts count
means less handling and inventory, reduced assembly and testing,
lower power consumption and improved reliability.
For more complex applications, Signetics offers a broad range of
8X300 family and compatible devices. These devices are illustrated
in Figure 1-1, and further information relative to them may be
obtained through the offices listed in the back of this manual.
