CIRCUIT
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.

Serial data input pin. Enters serial data of 16-bit in length.
Outputs data from 16-bit shift register that reads serial data or parallel data.
Shift clock input pin. At the rise of shift clock, input signal from the SI pin is entered into the 16-bit
shift register.
Entry of low level into the EN pin starts to read data.
Putting 16-bit data at high level after input loads the input data to a specified register.
Special output pin for 8-bit D-A converter (DAC)
Pin that shares I/O and DAC output.
Settings can be selected with serial data.
D4 to D11 are connected to the VDD power supply.
Digital input output pin.
Digital block power supply pin.
