MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M66008P/FP M66008P/FP 16-BIT I/O EXPANDER 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) SERIAL DATA OUTPUT SERIAL DATA INPUT DO ← 1 DI → 2 CS → 4 VCC 5 DO DI CLK CS D1 D2 D3 D4 D5 24 ↔ D1   23 ↔ D2    22 ↔ D3    CLOCK INPUT CLK → 3 CHIP SELECT INPUT 21 ↔ D4  20 19 18 17 16 15 14 13 SET INPUT S→ 6 GND 7 S D6 D7  D16    D15 PARALLEL DATA   INPUT/OUTPUT  ...
