The STM32L496RET6 from STMicroelectronics is a STM32L496xx series ultra-low power ARM® Cortex®-M4 32bit microcontroller with floating point unit (FPU) in 64 pin LQFP package. The Cortex-M4 core features FPU single precision which supports all ARM single precision data processing instructions and data types. It implements full set of DSP instructions and MPU which enhances application security. The device embeds 512Kbyte flash, 320Kbyte SRAM, quad SPI flash memories interface, extensive range of enhanced I/Os and peripherals connected to 2 APB buses, 2 AHB buses and 32bit multi-AHB bus matrix. It features 2 (16bit) advanced control, 5 (16bit)/2 (32bit) general purpose, 2 (16bit) basic, 2 (16bit) low power, 1 SysTick and 2 watchdog timers. It also features 3 tamper pins, 52 GPIOs, 4 wakeup pins, 21 capacitive sensing channels, three 12bit ADC (16 ch), two 12-bit DAC, internal voltage reference buffer, 2 comparator and 2 op-amp.
