ST62T40BQ6 Description
The STM32F756xx devices are based on the high-performance ARM? Cortex?-M7 32-bit RISC core operating at up to 216MHz frequency. The Cortex?-M7 core features a single floating point unit (SFPU) precision which supports all ARM? single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances the application security. The STM32F756xx devices incorporate high-speed embedded memories with a Flash memory of up to 1Mbyte, 320Kbytes of SRAM (including 64Kbytes of Data TCM RAM for critical real-time data), 16Kbytes of instruction TCM RAM (for critical real-time routines), 4Kbytes of backup SRAM available in the lowest power modes, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, a 32-bit multi-AHB bus matrix, and a multi-layer AXI interconnect supporting internal and external memories access.
