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
