Mitsubishi M62320P, M62320FP Datasheet
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
2
thanks to the adoption of the two-line I
C 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
2
C BUS.
I
• Built-in power-on reset.
APPLICATION
I/O port expansion for a microcontroller.
Data conversion between serial and parallel in
microcontroller peripherals.
