Datasheet STM32F439IIT6

STM32F429/439 Microcontrollers, STMicroelectronics

The STM32 F429/F439 microcontroller are based on the ARM^® Cortex™ M4 microcontroller with 180 MHz CPU operating up to 256 KB SRAM and up to 2 MB of dual bank Flash with SDRAM interface, Chrom-ART and LCD-TFT controller. The STM32F439 crypto/hash processor provides hardware acceleration for AES 128, 192, 256, Triple DES, and hash (MD5, SHA-1).
ST’s STM32 F429/439 Cortex M4 core architecture offers enhanced I/Os and peripherals which include Serial Audio Interface (SAI), true number random generator (RNG) and RTC, DACs, ADCs, 16-bit and 32-bit timers. As well as power saving modes that allow the design of low-power applications. In addition to this it has an Ethernet MAC and camera interface for CMOS sensors. The STM32 F429/439 32-bit Flash MCUs feature a Floating point unit (FPU) with digital signal processing (DSP) instructions and a memory protection unit (MPU) which increase your application security.

They will cover a wide range of applications which include motor drive and application control, Industrial applications: Inverters, PLC, scanners, HVAC, video intercom, Home audio appliances and Medical equipment.
