STM32L431CBY7TR Product Details

STM32L431CBY7TR Overview


Packaged in a 49-UFBGA, WLCSP format, this MCU is available in a compact size. There are 39 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 32-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The STM32L4 series includes this electrical component. There is 128KB 128K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a ARM® Cortex®-M4 Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. During the manufacturing process, 49 terminations were applied to the IC chip. 32-bits are used in Microcontroller. The MCU chip's supply output is 1.8V volts. Currently, MCU chip has YES DMA channels. Alternatives can be found by looking at the base part number STM32L431. There are YES PWM channels on the device. The clock function of this device is based on a 48MHz-frequency.
