The newest members to the ML610Q4xx series of low-power microcontrollers from LAPIS Semiconductor (formerly OKI Semiconductor) will give designers even more choices when creating products that provide comprehensive control over the operation of battery-powered devices used for the measurement and display of temperature, humidity and carbon monoxide (CO) in industrial and commercial environments. These new devices feature an RC-type analog-to-digital converter (RC-ADC) that provides accurate (±1.0°C) temperature measurement using only passive components.

RC-type ADCs simplify the external circuit and the software necessary to perform measurements and require less power than systems employing a separate ADC to convert the sensor input. The ML610Q4xx series offers versions with either FLASH memory or masked ROM to store the program that controls the display, user interface, communication ports and the taking of measurements. The newest members of the family feature in-circuit programmable FLASH which benefits designers by allowing on-chip, non-volatile data storage and the ability to make program changes in the field.

“Environmental sensing and monitoring products typically require a microcontroller to take measurements, manage collected data, display information, manage user inputs and provide communication of recorded data,” said Alec Melnick, ROHM’s Sr. Product Marketing Manager. “This new series of devices with RC-ADCsare providing product designers exceptional measurement and control capabilities with extended battery life and fewer components.”

Development kits, evaluation boards, debug hardware and PC-based software development tools are available to facilitate the design of ML610Q4xx series-based products.
