EFM32G840F32-QFN64T Product Details

EFM32G840F32-QFN64T Overview


A 64-VFQFN Exposed Pad package is included. In total, it has 56 inputs and outputs. This Microcontroller is mounted using the Surface Mount mounting type. Powered by the 32-Bit core, it offers a wide range of capabilities. The type of memory that the program uses is FLASH. The temperature range of this Microcontroller is within the range of -40°C~85°C TA. Gecko series components belong to this electrical component. Its program memory size is 32KB 32K x 8. There is a ARM® Cortex®-M3 Core Processor inside MCU that provides this device with its power. 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. 32kB memory size belongs to the part. A good performance can be achieved at a frequency of 32MHz, 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. A total of 4 timers/counters are included in the package. Devices based on the CORTEX-M3 series of CPUs are embedded in the device. It is built on a ARM core architecture.
