M66010FP

MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M66010FP/GP M66010FP/GP 24-BIT I/O EXPANDER 24-BIT I/O EXPANDER DESCRIPTION M66010 Semiconductor Integrated Circuit inputs 24-bit data in series and outputs it in parallel and vice versa, using shift register function. Equipped with 2 independent shift registers, one for serial-toparallel, the other for parallel-to-serial, this IC is able to read serial input data into a shift register while converting data from parallel to serial. Parallel input/output pins are set to input or output according to the bit. The M66010 is useful in a wide range of applications, such as MCU (micro controller unit) input/output port extension and serial bus system data communication. FEATURES Two-way serial data communication with MCU Serial data intake possible during parallel-to-serial conversion Parallel input/output switchable according to the bit Low power dissipation: 100µW maximum per package (VCC =5V, Ta = 25˚C, quiescent) Schmidt input (DI, CLK, S, CS) Open drain output (DO, D1 thru D24) Parallel data input and output (D1 thru D24) Wide operating supply voltage range (VCC = 2V ~ 6V) APPLICATION MCU-related serial-parallel data conversion, serial bus control by MCU, etc. FUNCTION The M66010 is produced by using the silicon gate CMOS (complementary metal-oxide semiconductor) technology. It is distinguished for low power dissipation and high noise resistance. Because two independent shift registers are built in, one for...
