STM32L431KBU6TR Product Details

STM32L431KBU6TR Overview


Packaged in a 32-UFQFN Exposed Pad format. A total of 26 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 32-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A STM32L4 series electrical component is used in this application. This program has a program memory of 128KB 128K x 8 bytes, which is the size of the program. With a ARM® Cortex®-M4 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 32 terminations on the IC chip, which means there are 32 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 1.8V volts. The system has YES channels for DMA communication. Alternatives can be found by searching through the base part number STM32L431 to find them. This MCU Chip uses YES PWM channels to operate. It runs on a 48MHz clock.
