Two years later, Intel launched the 8080, employing the new 40-pin DIL packages originally developed for calculator ICs to enable a separate address bus. It had an extended instruction set that is source-compatible (not binary compatible) with the 8008 and also included some 16-bit instructions to make programming easier. The 8080 device was eventually replaced by the depletion-load-based 8085 (1977), which used a single +5 V power supply instead of the three different operating voltages of earlier chips.Made possible with depletion-load nMOS logic (the 8085 was later made using HMOS processing, just like the 8086). Other well known 8-bit microprocessors that emerged during these years are Motorola 6800 (1974), General Instrument PIC16X (1975), MOS Technology 6502 (1975), Zilog Z80 (1976), and Motorola 6809 (1978).
