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.
