Analog Devices Inc. ADuCRF101 精密模拟微控制器，具有射频收发器、ARM Cortex-M3

亚德诺半导体 ADuCRF101 精密模拟微控制器是完全集成的数据采集解决方案，专为低功率、无线应用而设计。它具有一个 12 位模数转换器 (ADC)、一个低功率 ARM® Cortex®-M3 处理器，一个 862 MHz 至 928 MHz 和 431 MHz 至 464 MHz RF 收发器以及闪存®/EE 存储器。ADuCRF101 采用 9 mm × 9 mm LFCSP 封装。

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.
