STM32L552MEY6QTR Overview

Packaged in a 81-UFBGA, WLCSP format. A total of 51 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 STM32L5 series electrical component is used in this application. This program has a program memory of 512KB 512K x 8 bytes, which is the size of the program. With a ARM® Cortex®-M33 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER RISC uPs/uCs/peripheral parts. There are 81 terminations on the IC chip, which means there are 81 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 3V volts. The system has YES channels for DMA communication. This MCU Chip uses YES PWM channels to operate. It runs on a 48MHz clock.
