Zilog Z80 microprocessor is an 8-bit CPU object-code compatible
with Intel 8080 CPU.
The Z80 includes full set of 8080 registers and instructions, and
supports 8080 interrupts. In addition to that, the Z80 has many enhancements:
- 80 new instructions, including block transfer, bit and string manipulation instructions.
- 2 new index registers and a duplicate set of general-purpose and status registers.
- New types of interrupts for Z80 and non-Z80 peripheral devices.
- Single +5V voltage.
The Zilog Z80 microprocessor was second sourced by many companies. Clones of this processor were manufactured in East Germany, Romania and Soviet Union.

SHARP Corporation manufactured Z80 microprocessors using NMOS and CMOS technology processes. NMOS processors had part number LH0080, ran at frequencies up to 8 MHz, and we fully pin- and object code compatible with Zilog Z80. SHARP CMOS microprocessors used LH5080 part number. These processors were produced at 2.5 and 4 MHz, and offered an order of magnitude lower power consumption than LH0080 NMOS CPUs. Some CMOS parts had power-save function enabled.

40-pin ceramic DIP
Very rare version of the Zilog Z80 processor in white ceramic package. Z80 microprocessors were released in July 1976 (May 1976 according to Federico Faggin's www.intel4004.com website). Production date of the chip on the picture is 23th week of 1976 (end of May or beginning of June) - one month before the CPU family was officially released or a few weeks after that (if the May 1976 introduction date is correct).
