R8A66154SP Datasheet 8-bit I/o Expander

Manufacturer: Renesas

Overview: R8A66154SP 8-bit I/O EXPANDER WITH LED DRIVE FUNCTION REJ03F0285-0100 Rev. 1.00 Dec.08.

General 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.

Key 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℃).
