描述 Description

The MVI MSU2051 series product is an 8 - bit single chip microcontroller. It provides hardware features and a powerful instruction set, necessary to make it a versatile and cost effective controller for those applications demand up to 32 I/O pins or need up to 64 K byte external memory either for program or for data or mixed.

A serial input / output port is provided for I/O expansion, Inter - processor communications, and full duplex UART.
