DESCRIPTION
The M66006 is a semiconductor integrated circuit which has
12-bit shift register function to execute serial-parallel conver-
sion and parallel-serial conversion.
Because a serial-parallel shift register and a parallel-serial
shift register are independently built in this IC, it is possible to
read serial input data to a shift register while converting par-
allel data into serial data. Also, parallel data I/O pins can be
set to input mode or output mode bit-by-bit.
The M66006 can be widely used for I/O port expansion of
MCU, serial bus system data communication, etc.
FEATURES
• Bi-directional serial data communication with MCU
• Read of serial data during parallel-serial conversion.
• Bit resolution of serial data I/O
• Low power dissipation (50 W/package max.)
• Schmitt input (DI, CLK, S, CS)
• Open drain output (DO, from D1 to D12)
• Parallel data I/O (from D1 to D12)
• Wide operating supply voltage range (V
• Wide operating temperature range (T
APPLICATION
Serial-parallel data conversion, parallel-serial data conver-
sion, serial bus control by MCU.
