R8A66152SP
12-BIT I/O EXPANDER WITH LED DRIVE FUNCTION
REJ03F0259-0100
Rev. 1.00
Jan.9.2008
DESCRIPTION
R8A66152 is a semiconductor integrated circuit which has 12-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.
R8A66152 is useful in a wide range of applications, such as MCU (micro controller unit) I/O port extension
and serial bus system data communication.
Moreover, R8A66152 can be used as the anode common LED drive, too.
