U80701

The U80701 is a 32-bit microprocessor developed from 1986-1990 in the German Democratic Republic. It was manufactured by VEB Mikroelektronik "Karl Marx" Erfurt in NMOS technology and is encased in a ceramic quad flat package.

Microprocessor

The U80701 was developed by reverse engineering the MicroVAX 78032 microprocessor of the Digital Equipment Corporation. It is used in the Robotron K 1820 minicomputer - a clone of the DEC MicroVAX II.
The microprocessor used the 40 MHz input clock.
The U80700 system includes the following chips:

U80701: CPU
U80703: FPU
U80707: Console interface/controller DLART
U80709: CPU interface gate array
U80711: Q22-Bus interface gate array
