April 1972
8008 0.5MHz
8008-1 0.8MHz
P-channel silicon gate MOS technology
8 Bit microprocessor
3500 , 10 Micron
16K x 8-bits
48 with a 8 level stack, seven 8-bit registers and interrupt
abilities
The 8008 was developed in tandem with the
4004
and was intended
to be a custom chip for CTC but was rejected because it
was too slow.
The Intel 8008 was the first 8-bit CPU. This Processor was
available in two different speed. Because of the 8-bit
data bandwidth the clock speed was
slower than the
4004. The Intel 8008 can
address up to 16KB of memory, and was
developed in tandem with the 4004 and was intended to be a
custom chip
for Computer Terminal Corporation's (CTC)
new systems.
But the performance of the 8008 was lower than expected and CTC
rejected
this processor.
