EFM32LG840F128-QFN64T Product Details

EFM32LG840F128-QFN64T Overview


Packaged in a 64-WFQFN 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. 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. There is 128kB memory size assigned to the part. At a frequency of 48MHz, Microcontroller can operate efficiently. Chips have 64 pins. There are 5 timers/counters in this device. The CORTEX-M3 CPU family is embedded in the device, so it can handle a wide range of operations. It is equipped with a ARM core architecture which is integrated into it.
