REJ03F0285-0100 Rev. 1.00 Dec.08.2009
DESCRIPTION
R8A66154 is a semiconductor integrated circuit which has 8-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. R8A66154 is useful in a wide range of applications, such as MCU (micro controller unit)...
