EFR32MG29B140F1024IM40

The EFR32MG29B140F1024IM40 is an ideal solution for tiny, low-power devices that benefit from advanced security and high memory like portable and wearable medical devices, asset tracking tags, and battery powered sensors. With key features like high-capacity RAM and Flash memory, high-performance RF, a compact QFN package, coulomb counter, and Secure Vault™ High, it allows device makers to add high-performance and secure ultra-low-power Bluetooth LE on extremely compact wireless devices. The large memory of up to 1 MB of Flash and 256 kB of RAM, and 26 GPIO provides maximum resources for software, designs, protocols, and peripherals while leaving room for growth.
