Description
The MVI MV20556 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 mouse
applications which needs up to 4K byte internal
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.
