CSP Package EFM32™ Wonder Gecko 32-bit MCUs

Silicon Labs CSP Package EFM32™ Wonder Gecko 32-bit MCUs are based on the ARM® Cortex®-M4 core, which provides a complete DSP instruction set and includes a hardware FPU for faster computation performance. Wonder Gecko MCUs feature up to 256kB of flash memory, 32kB of RAM, and CPU speeds up to 48MHz. These new CSP packages offer energy-friendly MCU in 60% smaller packaging enabling a breakthrough in industrial design for small portable devices.

CSP Package EFM32™ Leopard Gecko 32-Bit MCUs

Silicon Labs CSP Package EFM32™ Leopard Gecko 32-Bit MCUs are part of the world's most energy-friendly microcontrollers and will provide Flash memory configurations up to 256KB with the added option of embedded USB connectivity, direct-drive TFT, EBI, and CPU speeds up to 48 MHz. These new CSP packages offer the world's most energy-friendly MCU in 60% smaller packaging enabling a breakthrough in industrial design for small portable devices. Within portable devices, the electronics and battery often dictate the physical size of the industrial design, and these new products help with both aspects. EFM32 energy efficiency allows you to select a smaller battery, and the new CSP package allows your PCB to be smaller. All Leopard MCUs include the same autonomous, low-energy peripherals found in the Gecko family, like AES encryption, Pulse Counter, Low Energy UARTs, in addition to the Low Energy Sensor interface LESENSE and on-chip Operational Amplifiers. These devices target energy-sensitive applications with high memory requirements and connectivity requirements.
