STM32F405RGT7TR Description
The STM32F405xx and STM32F407xx family is based on the high-performance Arm?Cortex?-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4core features a Floating point unit (FPU) single precision which supports all Arm singleprecision data-processing instructions and data types. It also implements a full set of DSPinstructions and a memory protection unit (MPU) which enhances application security.The STM32F405xx and STM32F407xx family incorporates high-speed embeddedmemories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes ofbackup SRAM, and an extensive range of enhanced I/Os and peripherals connected to twoAPB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
