Up to 2MB Flash and 512KB RAM built-in

ST has launched the new microcontrollers (MCUs) STM32F767/769. According to ST, the newly introduced microcontrollers feature rich memory, graphics, and communication peripherals, enabling the processing performance and efficiency of the ARM® Cortex®-M7 to be applied more broadly to applications such as portable/wearable devices, smart building and industrial controllers, smart home appliances, and personal or point-of-care (PoC) medical devices.

This new product in the STM32 MCU family is suitable for tasks such as high-performance control and simplifying user interfaces. It uses a 216 MHz/462 DMIPS/1082 EEMBC® CoreMark® Cortex-M7 core that includes double-precision floating-point units and DSP instructions. Along with this core, it also incorporates up to 2 MB of dual-bank flash, ST’s Chrom-ART Accelerator™ which provides powerful graphics performance, a hardware JPEG accelerator, a TFT-LCD controller, and a MIPI®-DSI[1] host controller. [1] Note: STM32F769/STM32F779 devices only.

You can add high-performance graphics and rendering effects to graphics applications

Such abundant on-chip resources add high-performance graphics and rendering effects to graphics applications that cannot be found in the performance of other microcontrollers. It also includes powerful audio features, such as an I2S interface, SAI (Serial Audio Interface), audio PLL, and DFSDM (Digital Filter for Sigma-Delta Modulators) that can connect digital microphones or external sigma-delta ADCs.

The STM32F767/769 features 512KB of RAM and a large 16KB data and instruction cache. It simplifies off-chip memory expansion through the Flexible Memory Controller (FMC) and Quad-SPI interface, effectively eliminating limitations on application code size. Furthermore, the on-chip flash supports read-while-write (RWW), ensuring smooth application performance and continuous operation even when software updates occur simultaneously.

The STM32F767/769 further enhances the capabilities of the STM32F7 series, and cryptographic/hash engine options (based on STM32F777/779 devices) are available for security-critical applications. As fellow Cortex-M7 devices, these products provide an upgrade path from the STM32F469/479 Cortex-M4 devices, which feature similar graphics and memory capabilities. The related ecosystem offers various features that enable developers to achieve advanced graphics performance for applications such as human-machine interfaces.

STM32F767/769 microcontrollers are currently available as samples, and mass production will begin in May 2016. Pricing for orders of 10,000 units starts at $10.95 for the STM32F769NIH6 and $7.96 for the entry-level STM32F767VGT6 (1MB Flash, 512KB RAM, TFT, LQFP100).
