Silicon Labs EFM32 Pearl Gecko MCU
Silicon Labs Pearl Gecko 32ビットマイクロコントローラ（MCU）ファミリは、強力な32ビットARM® Cortex®-M4と一連の周辺機器を提供します。 周辺機器には、AES、ECC、SHAに対応する固有の暗号化ハードウェアエンジンがあります。 Pearl Gecko 32ビットMCUは、超低電流アクティブモードと省エネモードからの短いウェイクアップ時間も特徴です。 Pearl Gecko MCUは、バッテリ駆動アプリケーションおよびその他の高性能および低エネルギー消費が必須のシステムに理想的です。
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.
