Mouser stocks Analog Devices’ ADuCRF101 wireless data-acquisition system

Feb. 25, 2015

Mouser Electronics announced today it is now stocking the ADuCRF101 precision analog microcontroller with RF transceiver from Analog Devices. The ADuCRF101 is a fully integrated data-acquisition system-on-a-chip designed for low-power wireless applications. It features a 6-channel 12-bit analog to digital converter (ADC) built around a 16-MHz ARM Cortex-M3 core, as well as a complete wireless RF transceiver. On-chip memory includes 128 KB of flash, part of which can be partitioned to be used like EEPROM, and 16 KB of SRAM, all in a package just 9 mm x 9 mm. This new microcontroller targets Internet of Things as well as smart meters, home automation, process and building control, wireless mesh networks, and the latest IEEE 802.15 Smart Utility Networks (SUN) applications.

The ADuCRF101 contains everything needed to implement a wireless data-acquisition system, including analog 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 167 kS/s. 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, 862 MHz to 928 MHz and 431 MHz to 464 MHz, covering the worldwide license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. 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 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.
