STM32F733IET6 Description
The STM32F732xx and STM32F733xx devices are based on the high-performance Arm?Cortex?-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex?-M7 corefeatures a single floating point unit (SFPU) precision which supports Arm? single-precisiondata-processing instructions and data types. It also implements a full set of DSP instructionsand a memory protection unit (MPU) which enhances the application security.The STM32F732xx and STM32F733xx devices incorporate high-speed embeddedmemories with a Flash memory up to 512 Kbytes, 256 Kbytes of SRAM (including64 Kbytes of data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM(for critical real-time routines), 4 Kbytes of backup SRAM available in the lowest powermodes, and an extensive range of enhanced I/Os and peripherals connected to two APBbuses, two AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnectsupporting internal and external memories access.
