Microcontrollers are graphic-centric with ARM Cortex-M7 core Andy Pratt January 22, 2016 ICs & Semiconductors, Wearable Opening up possibilities for portable or wearable devices, smart building and industrial controllers, smart appliances and medical equipment, the STM32F767 and STM32F769 microcontrollers have up to 2Mbyte flash and 512kbyte RAM. They feature a 216MHz/462DMIPS/1082 EEMBC CoreMark Cortex-M7 core with double-precision floating-point unit and DSP instructions. Integrated alongside the core are up to 2MB of dual-bank Flash, ST Microelectronic’s Chrom-ART Accelerator for powerful graphics performance, a hardware JPEG accelerator, TFT-LCD controller, and MIPI-DSI (Mobile Industry Processor Interface Display Serial Interface) host controller. Audio features include an I2S interface, Serial Audio Interface (SAI), audio PLLs, and DFSDM (Digital Filter for Sigma-Delta Modulators) for connecting a digital microphone or external sigma-delta ADC. In addition to 512kbyte RAM, the microcontrollers also have 16kbyte data and instruction caches. The Flexible Memory Controller (FMC) and Quad-SPI are claimed to simplify off-chip memory expansion for practically unlimited application code size, says the company. On-chip flash allows read-while-write for seamless application performance and continuous operation even while simultaneously updating software. The microcontrollers are sampling now and will enter mass production in May 2016. http://www.st.com/stm32f7series WEARTECHDESIGN.COM – Latest News/Advice on Technology for Wearable Devices Weartechdesign is unlike any other website currently serving the technology for wearable devices.
