GENERAL DESCRIPTION

The M62320P/FP is a CMOS 8-bit I/O expander which has serial to parallel and parallel to serial data converting functions.

It can communicate with a microcontroller via few wiring thanks to the adoption of the two-line I2C BUS.

Parallel data I/O terminal can be set to input or output mode alternatively in individual bits.

Maximum 8 ICs can be connected to a bus by using three chip-select pins, so that it is possible to handle up to 64 bits data.

FEATURES

• Simple two-line (SCL and SDA) communication with a microcontroller.

• 8-bit data conversion between serial and parallel by I2C BUS.

• Built-in power-on reset.

APPLICATION

I/O port expansion for a microcontroller.

Data conversion between serial and parallel in microcontroller peripherals.
