The ADUCM361 is a fully integrated 24-bit data acquisition system that incorporates dual high performance, multichannel sigma-delta analog-to-digital converters, 32-bit ARM Cortex™-M3 processor, and flash/EE memory on a single chip. The ADUCM360 is designed for direct interfacing to external precision sensors in both wired and battery-powered applications. The ADUCM361 contains all the features of the ADuCM360 except that only one 24-bit ADC is available.
The ADUCM360 contain an on-chip 32 kHz oscillator and an internal 16MHz high frequency oscillator. The high frequency oscillator is routed through a programmable clock divider from which the operating frequency of the processor core clock is generated. The maximum core clock speed is 16 MHz; this speed is not limited by operating voltage or temperature.
The ADuCM360/ADuCM361 are specifically designed to operate in battery-powered applications where low power operation is critical. The microcontroller core can be configured in a normal operating mode that consumes 290 ?A/MHz. This mode allows the part to operate with ultralow power and still respond to asynchronous external or periodic events.
