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.
