Description
The MVI U2031 is an 8 - bit single chip microcontroller. It provides hardware features and powerful instruction set that are necessary to make it a versatile and cost effective controller for those applications need up to 64K byte external memory either for program or for data and mixed.
A serial input / output port is provided for I/O expansion, Inter - processor communications, full duplex UART.
