The ADuCM320 is a fully integrated single package device that incorporates high performance analog peripherals together with digital peripherals controlled by an 80 MHz ARM® Cortex™-M3 processor and integral flash for code and data.

The ADC on the ADuCM320 provides 14-bit, 1 MSPS data acquisition on up to 16 input pins that can be programmed for single-ended or differential operation. The voltage at the IDAC output pins may also be measured by the ADC, which is useful for controlling the power consumption of the current DACs. Additionally, chip temperature and supply voltages can be measured.

The ADC input voltage is 0 V to VREF. A sequencer is provided, which allows a user to select a set of ADC channels to be measured in sequence without software involvement during the sequence. The sequence can optionally repeat automatically at a user selectable rate.

Up to eight VDACs are provided with output ranges that are programmable to one of two voltage ranges. The VDAC outputs have an enhanced feature of retaining their output voltages during a watchdog or software reset sequence.

Four IDAC sources are provided. The output currents are programmable with ranges of 0 to 150mA. A low drift band gap reference and voltage comparator complete the analog input peripheral set.

The ADuCM320 has a low power ARM Cortex-M3 processor and a 32-bit RISC machine that offers up to 100 MIPS peak performance. Also integrated on chip are 2 × 128 kB Flash/EE memory and 32 kB of SRAM. The flash comprises of two separate 128 kB blocks supporting execution from one flash block and simultaneous writing/erasing of the other flash block.
