Technology Atlanta Selects Oki's ML67Q4002 Advantage Microcontroller

10/6/2004 - Technology Atlanta Corporation, an engineering consulting firm for the industrial process market, announced a new water quality monitoring system, which will use Oki Semiconductor's ML67Q4002 Advantage MicrocontrollerTM as its primary system processor. Technology Atlanta's new design provides the control electronics for a poultry drinking water monitoring and Iodine injection system called the IoPro System that has been patented by IoSolutions Inc. and is marketed in the United States by IoGold Systems Inc., a leader in water quality management and purification systems for the poultry industry.

Technology Atlanta serves an industrial market where customers have stringent system design requirements that includes innovative system features with competitive system costs. Oki's ML67Q4002 Advantage MicrocontrollerTM, with its highly integrated set of general purpose peripherals and its high performance 32-bit ARM architecture, provides Technology Atlanta with an effective MCU solution to meet these demanding system requirements.

Oki's ML67Q4002 Advantage MicrocontrollerTM is at the center of the controller board designed by Technology Atlanta to monitor water temperature and usage. The device controls a water heater and an injection pump, which adds elemental Iodine to the drinking water of broiler and layer chickens. The many peripherals available on Oki's Advantage Microcontroller are used to collect data from a variety of sensors and communicate via an Infrared Data Association (IrDA) interface, which enables operator control and billing data collection. Moreover, the ARM industry-standard architecture allowed easy porting of eCosTM, an open source RTOS, which Technology Atlanta uses as a basis for many of its designs.

Commenting on the use of Oki's Advantage Microcontroller in the IoGold Systems IoPro product, Peter Wilcox, principal engineer, Technology Atlanta, said, "The flexibility and richness of Oki's MCU peripheral set allowed several cost saving optimizations, such as combination of an unused DMA port and a timer to provide event counting and rate monitoring with very little CPU overhead and no additional hardware. Thanks to the widely supported ARM architecture, we are using Oki's ML67Q4002 Advantage Microcontrollers in several designs to lower our cost of development. Having the eCos RTOS running on an Oki MCU allows us to implement our next project more quickly and efficiently."

"We are pleased that Technology Atlanta selected us as a supplier of a core component in their designs for IoGold Systems," said Eric Nguyen, senior product marketing manager, Oki Semiconductor. "Oki is committed to providing our customers with the most advanced and competitive ARM-core based solutions, as well as the best technical support and service that will enable them to be successful in their respective market places."
