Figure 17. Minimum Z80 Computer System
Because the Z80 CPU requires only a single 5V power supply, most small
systems can be implemented using only this single supply.
The external memory can be any mixture of standard RAM, ROM, or
PROM. In Figure 17, a single 8K bit ROM (1 Kbytes) comprises the entire
memory system. The Z80 internal register configuration contains sufficient
Read/Write storage, requiring no external RAM memory.
I/O circuits allow computer systems to interface with the external devices.
In Figure 17, the output is an 8-bit control vector and the input is an 8-bit
status word. The input data can be gated to the data bus using any standard
three-state driver while the output data can be latched with any type of stan-
dard TTL latch. A Z80 PIO serves as the I/O circuit. This single circuit
attaches to the data bus as indicated and provides the required 16 bits of
TTL compatible I/O. (Refer to the Z80 CPU Peripherals User’s Manual for
details on the operation of this circuit.) This powerful computer is built with
only three LSI circuits, a simple oscillator, and a single 5V power supply.
