EFM32LG842F128G-E-QFP64 Product Details

EFM32LG842F128G-E-QFP64 Overview


A TQFP package is included. In total, it has 53 inputs and outputs. MICROCONTROLLER, RISC uPs, uCs, and peripheral ICs make up the Microcontroller. Microcontroller is known that the chip has 64 terminations in total. The part works on a 32-bit basis. An output voltage of 3V volts is available for this Microcontroller chip. The Microcontroller chip has YES DMA channels. 128kB memory size belongs to the part. A good performance can be achieved at a frequency of 48MHz, as long as it is operated at a low power consumption. In order for the device to work with the motor, it utilizes the PWM channel YES. On the chip, there are 64 pins that are accessible. A total of 5 timers/counters are included in the package. There's built-in FLASH memory in the equipment. It is built on a ARM core architecture. This 8 Programmable I/O section allows you to program the device in many different ways depending on what you need.
