Intel MCS-40
The Intel 4040 ("''forty-forty''") is the second 4-bit microprocessor designed and manufactured by Intel. Introduced in 1974 as a successor to the Intel 4004, the 4040 was produced with a 10 μm process and includes silicon gate enhancement-load PMOS logic technology. The 4040 contained 3,000 transistors and could execute approximately 62,000 instructions per second. General performance, bus layout and arithmetic logic unit (ALU) were identical to the 4004. The main improvement was to use a larger 24-pin dual in-line package, giving it 8 more pins than the 16-pin 4004. Two of these were used to implement interrupts, which were lacking in the 4004 and considered a major oversight. Two more implemented a halt/stop system, which put the processor into a low-power mode and also allowed for single-step operation that made debugging much easier. Another pin was used to bank select a second read-only memory (ROM), doubling the amount of ROM the processor could address compared to ...
