STM32L476ZET6TR

STM32L476ZET6TR is an ultra-low-power Arm® Cortex®-M4 32-bit microcontroller. The Cortex-M4 core features a Floating point unit (FPU) single precision that 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 application security. It embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall. The device offers up to three fast 12bit ADCs (5 Msps), two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timer, two 16bit PWM timers dedicated to motor control, seven general-purpose 16bit timers, and two 16bit low-power timers. The device supports four digital filters for external sigma delta modulators (DFSDM).
