Overview
ARCHITECTURE
UM008005-0205
The ZiLOG Z80 CPU family of components are fourth-generation enhanced
microprocessors with exceptional computational power. They offer higher
system throughput and more efficient memory utilization than comparable
second- and third-generation microprocessors. The speed offerings from 6–
20 MHz suit a wide range of applications which migrate software. The
internal registers contain 208 bits of read/write memory that are accessible
to the programmer. These registers include two sets of six general purpose
registers which may be used individually as either 8-bit registers or as 16-bit
register pairs. In addition, there are two sets of accumulator and flag
registers.
The Z80 CPU also contains a Stack Pointer, Program Counter, two index
registers, a
to incorporate into a system since it requires only a single +5V power
source. All output signals are fully decoded and timed to control standard
memory or peripheral circuits; the Z80 CPU is supported by an extensive
family of peripheral controllers.
