R8A66151SP - Renesas Technology

R8A66151SP 24-BIT I/O EXPANDER

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 whil.

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~D24) Parallel data I/O pins (D1~D24) Wide supply voltage range (Vcc=2.0 to 6.0V) Wide operating temperature range (Ta=-40 to 85oC) APPLICATION Serial - parallel or parallel - serial data conversion for MCU peripheral. Serial bus control by MCU. PIN CONFIGURATION (TOP VIEW) SERIAL DATA OUTPUT SERIAL DATA INPUT DO DI 1 2 3 4 5 6 7 8 9 10 11 12 13 14 .
