R8A66151SP
24-BIT I/O EXPANDER
REJ03F0258-0100
Rev. 1.00

DESCRIPTION
R8A66151 is a semiconductor integrated circuit which has 24-bit shift register function to execute serial in -
parallel out conversion and parallel in - serial out conversion.
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.
R8A66151 is useful in a wide range of applications, such as MCU (micro controller unit) I/O port extension
and serial bus system data communication. R8A66151 is the succession product of M66010.
