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.
