1 / 5 page  MITSUBISHI 〈DIGITAL ASSP〉 M66008P/FP 16-BIT I/O EXPANDER 1 MITSUBISHI 〈DIGITAL ASSP〉 M66008P/FP 16-BIT I/O EXPANDER DESCRIPTION The M66008 is a semiconductor integrated circuit providing the 16-bit serial input-parallel output and parallel input-serial output shift register function. Independent built-in registers for serial input-parallel output and parallel input-serial output enable serial input data to be read into a shift register during output of serial data converted from parallel data. In addition, parallel data input/output pin can be placed in input or output mode in bits. The M66008 is widely applicable to I/O port extension for MCU, data communication of serial bus system, etc. FEATURES • Two-way serial data communication with MCU • Reading of serial data during parallel-serial data conversion • Division of I/O bit in parallel data input/output • Low power consumption of 50 µW/package maximum (Vcc=5V, Ta=25°C at time of standstill) • Schmitt triggered input (DI, CLK, S, CS) • Open drain output (DO, D1~D16) • With parallel data input/output (D1~D16) • Wide operating supply voltage range (Vcc=2~6V) • Wide operating temperature range (Ta=–20~75°C) PIN CONFIGURATION (TOP VIEW) BLOCK DIAGRAM CLOCK INPUT CLK SERIAL DATA OUTPUT SHIFT REGISTER !
