ADuCRF101 wireless data acquisition system now at Mouser

Analog Devices' ADuCRF101 Precision Analog Microcontroller with RF Transceiver contains everything needed to implement a wireless data acquisition system, including analogue and digital sensor inputs and an RF transceiver. The data acquisition section consists of a high-resolution 12-bit ADC with a programmable data rate of up to 167kSPS. The ADC has six channels which can be configured in either single ended or differential modes. In single-ended mode, the ADC can be used with sensors that have ratiometric outputs, such as transducers. Serial inputs include a UART, I2C, and SPI which can be used to interface to external sensors.

The on-chip RF transceiver operates over two frequency bands, 862MHz to 928MHz and 431MHz to 464MHz, covering the worldwide license-free ISM bands at 433MHz, 868MHz, and 915MHz. It is suitable for applications that operate under the European ETSI EN300-220, the North American FCC (Part 15), and the Chinese short-range wireless regulatory standards. The RF transceiver section supports ZigBee as well as custom wireless protocols. This high degree of integration significantly lowers Bill-of-Materials (BOM) costs.

This wireless data acquisition system is designed for battery-powered applications where low power is absolutely critical. The ADuCRF101 can be configured to operate under different low power modes under direct program control. A Flexi mode is available, which allows any peripheral to wake up the device. Hibernate mode allows only the internal wake-up timer to remain active. Shutdown mode is the lowest power mode and only an external interrupt can wake up the microcontroller.
