M62371GP 3 V Type 8-bit 36ch Selector SW Built-in D/A Converter with Buffer Amplifiers REJ03D0880-0201 Rev.2.01 Dec 27, 2007 Description The M62371GP is a CMOS semiconductor IC, containing 36 channels of 8-bit D/A converters. It is operable with a low supply voltage between 2.7 to 3.6 V, and is easy to use due to serial data input, and 3-pin (DI, CLK, LD) connection with microcomputer. The IC also contains DO pin terminal, enabling cascade connection, and therefore is suitable for automatic control in combination with a microcomputer. (M62371GP is an advanced product of M62370GP on its buffer amp. drivability.) Features • • • • Operable with a low voltage between 2.7 to 3.6 V 16-bit serial data input (connected via 3 pins: DI, CLK, LD) 36 channels built-in of 8-bit D/A converter 6 channels of D/A converters capable of selecting and outputting 4 data stored in each converter, through 2 control terminals Application Digital/analog conversion in industrial or home-use electronic equipment. Automatic control in combination with EEPROM and microcomputer (Substitute for conventional semi-fixed resistor).

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.
