M62376GP
8-BIT 12CH D-A CONVERTER IC BUILT-IN 12-BIT I/O EXPANDER
DESCRIPTION
The M62376GP is a semiconductor IC that adopts a CMOS
structure having 12-channel of 8-bit D-A converter and 12-bit I/O
expander. The IC has achieved a wide operation range of 2.7V to
5.5V in power voltage.
Data is easily available via 3-wire combination system serial input
of SI, CLK and EN. The IC also provides an SO pin enabling
cascade connection. It provides 8 pins that share D-A converter
and I/O ports that can be arbitrarily switched with serial
input data.
FEATURES
Supply voltage 2.7 to 5.5V
Adopts 4 special ports for each of DAC and I/O and 8 ports that
share DAC output and I/O.
Each port can be set by serial data for input/output status.
Built-in power-on reset where D-A output is set to "L" in the
initial status and I/O goes to Hi-impedance when power is
turned on.
Small package of 0.65mm pitch and 24 pin.
