LONDON — European chipmaker STMicroelectronics has introduced a family of ARM-based microcontrollers, the STR730F series, optimized for industrial applications at single-dollar unit prices. Expected applications include factory automation, appliances, test and measurement equipment, point-of-sale terminals, and security systems. A single 5V power rail is the preferred supply configuration for industrial applications that need robust operation, especially in terms of noise immunity, and the STR730F family is the first family of ARM-based microcontrollers to meet this need. In addition, the devices are specified over an extended temperature range of -40 degrees C to +105 degrees C and include a set of peripherals tailored for industrial applications, the company said. The family is based around the ARM7TDMI processor, also known as the Thumb. The microcontrollers also come with 64-kbyte to 256-kbyte of flash program memory.
