 Hi, let me present the other features that STM32L4 offers. So what else? Among other features, internal reference voltage buffer can provide stable reference for analog to digital and digital to analog converter and can be output on Vref plus pin for application needs. There are two voltages available, 2.048V when analog supply voltage is above 2.4V or 2.5V when the analog supply is above 2.8V. The flash interface is 64-bit wide. On top 8 bits are added for error checking and correction mechanism. The ECC can correct one mistake with an interrupt generated or detect two mistakes with a non-mescable interrupt available. Maximum flash speed with all weight states depends on supply voltage and its 16 MHz in range 1 or 6 MHz in range 2. The flash memory up to 1 MB is divided in two banks of 512 KB each with a read while write capability. The GPIOs offer analog input as a default configuration after power on and reset reducing current consumption. In standby mode the pull up and pull down resistors can be turned on to guarantee safe voltage levels on selected GPIOs. Further four programmable voltage detectors with fixed thresholds are implemented and connected to external interrupt unit. These are connected to the analog supply, digital supply, the supply for the IO ring number two and for the USB supply input and allow safe voltage domain turn on and turn off when STM32L4 is supplied from independent voltage sources. These programmable voltage detectors are by default turned off except the programmable voltage detector connected to the digital supply line. The resident clock controller offers additional low speed clock output from low speed internal RC oscillator or from the low speed external precise crystal oscillator. Window watchdog offers an early wake up function. When the counter is one step above reset an interrupt can be served to prevent the system reset in sleep mode.
