High-performance MCUs now available with up to 2 MB Flash and 512KB RAM
STMicroelectronics’ new STM32F767/STM32F769 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 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.
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 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 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.
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.
Hardware tools
The new STM32F7 discovery kit STM32F746G-DISCO offers all the needed features to allow developers or makers need to create their own final application. While this low-cost development platform will enable many new original products and applications, it also comes pre-loaded with a full set of demo software libraries which benefit from the many features of the STM32F7 microcontrollers and can be used as a reference. The fully loaded evaluation boards STM32756G-EVAL2 and STM32746G-EVAL2 are available for developers who want to access to the superset features of the STM32F7 series.
The STM32F767/769 microcontrollers are sampling now and will enter mass production in May 2016. Pricing for 10000-piece orders starts at $10.95 for the STM32F779NIH6 (2 MB Flash, 512 KB RAM, TFT, MIPI-DSI, Crypto, TFBGA216) or $7.96 for the entry-level STM32F767VGT6 (1 MB Flash, 512 KB RAM, TFT, LQFP100).
