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 can 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.Four IDAC sources are provided. The output currents are programmable with ranges of 0 mA to 150 mA. A low drift band gap reference and voltage comparator completes the analog input peripheral set.The ADuCM320 can be configured so that the digital and analog outputs will retain their output voltages and currents through a watchdog or software reset sequence. Thus, a product can remain functional even while the ADuCM320 is resetting itself.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 two separate 128 kB blocks supporting execution from one flash block and simultaneous writing/erasing of the other flash block.The ADuCM320 operates from an on-chip oscillator or a 16 MHz external crystal and a PLL at 80 MHz. This clock can optionally be divided down to reduce current consumption. Additional low power modes can be set via software. In normal operating mode, the ADuCM320 digital core consumes about 300 μA per MHz.The device includes an MDIO interface capable of operating at up to 4 MHz. The capability to simultaneously execute from one flash block and write/erase the other flash block makes the ADuCM320 ideal for 10G, 40G, and 100G optical
