Silicon Labs EFM32 Pearl Gecko MCU

Silicon Labs Pearl Gecko 32位元微控制器(MCU)系列提供強大的32位元ARM® Cortex®-M4和一系列周邊設備。 這些周邊設備包括支持AES、ECC和SHA的獨有密碼式硬件引擎。 Pearl Gecko 32位元MCU還具有超低電流主動模式，以及短喚醒時間的節能模式。 Pearl Gecko MCU理想適用於要求高效能和低功耗的電池供電應用及其它系統。

Silicon Labs offer EFM32PG12 Pearl Gecko MCUs which combine very low active current consumption, enhanced sleep mode capabilities, and integrated security features. This enables the next generation of secure, battery-operated IoT products. A large 1MB flash with dual-bank architecture and in-field update capability enables even richer applications that can be updated after product deployment.
