DSP, Micros & Memory
STMicroelectronics’ new STM32F767/769 microcontrollers (MCUs) with rich memory, graphics and communication peripherals bring ARM Cortex-M7 processing power and efficiency to a wide 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, these latest members of the extensive STM32 MCU family feature a 216 MHz/462 DMIPS/1082 EEMBC CoreMark Cortex-M7 core with double-precision floating point unit and DSP instructions.
Integrated alongside the core are up to 2 MB of dual-bank Flash, ST’s Chrom-ART Accelerator for powerful graphics performance, a hardware JPEG accelerator, TFT-LCD controller and MIPI-DSI1 host controller. 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 512 KB of integrated RAM, as well as large 16 KB data and instruction caches, while the Flexible Memory Controller (FMC) and Quad-SPI interface simplify off-chip memory expansion to allow 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.
The STM32F767/769 extend the performance potential of the STM32F7 series and provide the option of a crypto/hash engine (with STM32F777/779 devices) for security-conscious applications. As Cortex-M7 devices, they also provide an upgrade path from STM32F469/479 Cortex-M4 devices that have similar graphics and memory features. The associated ecosystem has features that help developers achieve high graphics performance for applications such as human-machine interfaces.
