EFM32LG840F128G-E-QFN64 Product Details

EFM32LG840F128G-E-QFN64 Overview


Packaged in a 64-VFQFN Exposed Pad format. A total of 56 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 Leopard Gecko 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®-M3 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 64 terminations on the IC chip, which means there are 64 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. There is 128kB memory size assigned to the part. At a frequency of 48MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 64 pins. There are 5 timers/counters in this device. It is equipped with a ARM core architecture which is integrated into it.
