DESCRIPTION
R8A66150 is a semiconductor integrated circuit which has 12-bit shift register function to execute serial in-
parallel out conversion and parallel in - serial outconversion.
Built in two shift registers for serial in - parallel out and parallel in - serial out are constructed independently,
This IC is able to read serial input data into a shift register while output the serial data converting from the
parallel data input.
Also, parallel data I/O pins can be set to input mode or output mode by a bit.
R8A66150 is useful in a wide range of applications, such as MCU (micro controllerunit) I/O port extension
and serial bus system data communication. R8A66150 is the succession product of M66006.
