8080 / 8080A :
The Intel 8080A is a complete 8-bit parallel central processing unit.
It is fabricated on a single LSI chip using Intel´s n-channel silicon
gate MOS process. This offers the user a high performance solution to control
and processing applications. The 8080A contains six 8-bit general purpose
working registers and an accumulator. The six general purpose registers
may be addressed individually or in pairs providing both single and double
precision operators. The 16-bit stack pointer controls the addressing of
an external stack. This stack gives the 8080A the ability to easily handle
multiple level priority interrupts by rapidly storing and resotring processor
status. It also provides almost unlimited subroutine nesting. The microprocessor
has been designed to simplify systems design. Separate 16-line addresses
and 8-line bidirectional data busses are used to facilitate easy interface
to memory an I/O.
Note : The 8080A is functionally and eletrically compatible with the
Intel 8080.
