ARM Cortex-M7 Powers More Applications with Graphics-Centric STM32 Microcontrollers

STMicroelectronics' new STM32F767/769 microcontrollers (MCUs) with rich memory, graphics and communication peripherals bring ARM Cortex-M7 processing power and efficiency to a wider range of applications such as portable or wearable consumer devices, smart-building and industrial controllers, smart appliances, and personal or point-of-care medical equipment.

Particularly well suited to simplifying the design of high-performance controls and user interfaces, the latest members of the extensive STM32 MCU family 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's Chrom-ART Accelerator for powerful graphics performance, a hardware JPEG accelerator, TFT-LCD controller, and MIPI-DSI[1] host controller.

The generous on-chip resources enable graphics applications to benefit from richness and rendering beyond the capabilities of other microcontrollers. There are also powerful audio features including 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.

The STM32F767/769 feature 512KB of integrated RAM, as well as large 16KB Data and Instruction caches, while the Flexible Memory Controller (FMC) and Quad-SPI interface simplify off-chip memory expansion allowing practically unlimited application code size. In addition, the on-chip Flash allows read-while-write for seamless application performance and continuous operation even while simultaneously updating software.
