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

(b) Initial status just after power is turned on:
Low level output from A1 to A4 (set to 00h)
D4/A12 to D11/A5: DAC output of high-impedance (Hi-Z), I/O of input mode (Hi-Z)
D0 to D3: input mode (Hi-Z)
(c) The DACHiZ command is effective only for DAC settings (A5 to A12), but not for the I/O ports (D0 to D11)
Note: To change the status of pins D4/A12 to D11/A5, switch both analog and digital after setup of high-impedance.

Note:
The RESET pin is directly connected with the power pin to use power-on reset. However, when
forced reset is done from outside, the capacitance (0.1 to 10 µF) should be connected between
RESET pin and ground to remove noise due to installation of line, etc.
Precaution for Use
This IC has two power supply pins and a ground pin. Superimposition of these pins with ripple and spike noise may
cause reduction of conversion accuracy and occurrence of malfunction. Be sure to insert a capacitor between each
power supply and the GND pin to stabilize D/A converting operation.
The output buffer amplifier of this IC has strong characteristics against capacitive load. Accordingly, when the
capacitance (10 µF Max) is connected between output and ground to remove jitter and noise due to installation of
output line, no problem may occur in operation of DAC. However, notice that the removal results in lengthening the
settling time.
This IC also provides power-on reset function. To assure the resetting operation, power supply should be turned on in
the order of timing shown in the diagram below.

application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products.
7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
(1) artificial life support devices or systems
(2) surgical implantations
(3) healthcare intervention (e.g., excision, administration of medication, etc.)
(4) any other purposes that pose a direct threat to human life
Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing
applications shall indemnify and hold harmless Renesas Technology Corp., its affiliated companies and their officers, directors, and employees against any and all
damages arising out of such applications.
9. You should use the products described herein within the range specified by Renesas, especially with respect to the maximum rating, operating supply voltage range,
movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas shall have no liability for malfunctions or damages
arising out of the use of Renesas products beyond such specified ranges.
10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific characteristics such as the occurrence of failure at a certain
rate and malfunctions under certain use conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and injury or damage
caused by fire in the event of the failure of a Renesas product, such as safety design for hardware and software including but not limited to redundancy, fire control and
malfunction prevention, appropriate treatment for aging degradation or any other applicable measures. Among others, since the evaluation of microcomputer software
alone is very difficult, please evaluate the safety of the final products or system manufactured by you.
11. In case Renesas products listed in this document are detached from the products to which the Renesas products are attached or affixed, the risk of accident such as
swallowing by infants and small children is very high. You should implement safety measures so that Renesas products may not be easily detached from your products.
Renesas shall have no liability for damages arising out of such detachment.
12. This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written approval from Renesas.
13. Please contact a Renesas sales office if you have any questions regarding the information contained in this document, Renesas semiconductor products, or if you have
any other inquiries.
