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 munication. Moreover, R8A66152 can be used as the anode mon LED drive, too. .. Features Bi-directional serial munication 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~D12). High output current IOL=24m A (at VCC=4.5V), IOL=15m A (at VCC=3.0V) Parallel data I/O pins (D1~D12) Wide supply voltage range (Vcc=2.0 to 6.0V) Wide operating temperature range (Ta=-40 to 85o C) APPLICATION Serial - parallel or parallel - serial data conversion for MCU peripheral.
