Analog Devices, Inc - Low Power Precision Analog Microcontroller - 18 June 2012

The ADuCM360 is a fully integrated, 4 kSPS, 24-bit data acquisition system incorporating dual, high performance multi-channel sigma-delta analog-to-digital converters (ADCs), 32-bit ARM Cortex M3® MCU, and Flash/EE memory on a single chip.

The part is designed for direct interfacing to external precision sensors in both wired and battery powered applications.

The device contains an on-chip 32 KHz oscillator and an internal 16MHz high-frequency oscillator. This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The maximum core clock speed is 16MHz and this is not limited by operating voltage or temperature.

The microcontroller core is a low power Cortex-M3 core from ARM. It is a 32-bit RISC machine, offering up to 20 MIPS peak performance.

The Cortex-M3 MCU incorporates a flexible 11-channel DMA controller supporting all wired (SPI, UART, I2C) communication peripherals. 128k Bytes of non-volatile Flash/EE and 8k Bytes of SRAM are also integrated on-chip.
