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) I/O port extension
and serial bus system data communication.
Moreover, R8A66154 can be used as the anode common LED drive, too.
FEATURES
Bi-directional serial communication with MCU
Serial data can be input during parallel to serial data conversion
Parallel data I/O pins can be set input mode or output mode by a bit
Schmitt input (DI, CLK, /S, /CS)
N-ch open drain output (DO, D1~D8).
High output current IOL=24mA (at VCC=4.5V), IOL=15mA (at VCC=3.0V)
Parallel data I/O pins (D1~D8)
Wide supply voltage range (Vcc=2.0 to 6.0V)
Wide operating temperature range (Ta=-40 to 85)
APPLICATION
Serial - parallel or parallel - serial data conversion for MCU peripheral.
Serial bus control by MCU.
LED array drive, The various LED display modules.
