DESCRIPTION

The M66006 is a semiconductor integrated circuit which has 12-bit shift register function to execute serial-parallel conversion 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 parallel 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 (50µW/package max.)

(VCC=5V, Ta=25°C, in quiescing)

• 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 (VCC=2 to 6V)

• Wide operating temperature range (Ta=–20 to 75°C)

APPLICATION

Serial-parallel data conversion, parallel-serial data conversion, serial bus control by MCU.
