ARM-based MCUs

STMicroelectronics (ST) unveiled a family of ARM-based MCUs that is specifically designed to address the emerging demand for high-performance, cost-effective and off-the-shelf 32-bit MCUs optimized for industrial applications such as 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, said ST, and the STR730F family is the first family of ARM-based MCUs to meet this need. In addition, the devices are specified over an extended temperature range of -40C to 105C, and has been designed to implement the main controller functions in complex industrial applications. For this reason, said the company, the device delivers very high performance via a 32MIPS ARM7TDMI RISC processor core; full-speed (zero wait state) access to up to 256KB of embedded Flash program memory; and a 16-channel DMA facility that significantly reduces the CPU load in complex applications.

"The new STR730F series builds on ST's track record as a world leader in integrating ARM cores into SoC solutions and standard microcontroller products, as well as our long-established expertise in providing full system solutions for our customers in a wide range of industrial markets," said Jim Nicholas, GM of ST's Microcontroller Division. "Complementing our existing STR710 devices, this new family demonstrates yet again ST's unique ability to draw upon the industry's broadest range of process, circuit, system, and applications expertise to deliver a product that is uniquely positioned to satisfy an important emerging demand."

Members of the STR730F family are offered in TQFP144 (20x20), TQFP100 (14x14) and BGA144 (10x10) packaging options. Like all of the company's MCU products, the STR730F family is part of a platform that includes hardware and software evaluation and development aids, as well as comprehensive on-line applications support, including free downloadable software and libraries.

Samples of the STR730F devices are already available, with prices (in 10,000 quantities) ranging from $4.53 for the STR736FV0 (TQFP100, 64K memory size, No CAN, 4xUART and 12xPWM) to $8.99 for the STR730FZ2 (TQFP144, 256K memory size, 3xCAN, 4xUART and 16xPWM).
