Analog Devices Inc. Microcontrôleur analogique de précision ADuCRF101 avec émetteur-récepteur RF, ARM Cortex-M3
Le microcontrôleur analogique de précision ADuCRF101 Analog Devices est une solution d'acquisition de données totalement intégrée conçue pour les applications sans fil de faible puissance. Il dispose d'un convertisseur analogique-numérique (CAN) de 12 bits, d'un processeur ARM® Cortex®-M3 à faible puissance, d'un émetteur-récepteur RF entre 862 MHz et 928 MHz et entre 431 MHz et 464 MHz et d'une mémoire Flash®/EE. Le composant ADuCRF101 est fourni en boîtier LFCSP 9 mm × 9 mm.
When configured in single-ended mode, they can be used for ratiometric measurements on sensors that are powered, when required, from the internal low dropout regulator (LDO). An internal battery monitor channel and an on-chip temperature sensor are also available. This wireless data acquisition system is designed to operate in battery-powered applications where low power is critical. The device can be configured in normal operating mode or different low power modes under direct program control. In flexi-mode, any peripheral can wake up the device and operate it. In hibernate mode, the internal wake-up timer remains active. In shutdown mode, only an external interrupt can wake up the device.
