Description

The M62376GP is a semiconductor IC that adopts a CMOS structure having 12 channels of 8-bit D/A converter and 12-

bit I/O expander. The IC has achieved a wide operation range of 2.7 to 5.5 V 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 5.5 V

• 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 high-impedance when

power is turned on

• Small package of 0.65 mm pitch and 24 pin

Application

Adjustment/control of industrial or home-use electronic equipment, such as VCR camera, VCR set, TV, and CRT

display.
