EFM32LG840F256-QFN64 Product Details

EFM32LG840F256-QFN64 Overview


There is a 64-WFQFN Exposed Pad package available. The board has 56 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 32-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. Leopard Gecko-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 256KB 256K x 8. Powered by a ARM® Cortex®-M3 Core processor. Microcontroller's a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. IC Chip terminations are 64. As a result, this Microcontroller comes with a 32-bit size. Input voltage for the chip is 3V volts. A total of YES DMA channels are available. This IC part has a memory size of 256kB. Performing well when operated at frequency 48MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 64 pins that can be accessed. It comes with 4 timers/counters that can be set up. The CPU is based on ARM cores.
