ADUCM320BBCZ

ADUCM320 is a fully integrated single-package precision analogue microcontroller device that incorporates high-performance analogue peripherals together with digital peripherals controlled by an 80MHz ARM CortexM3 processor and integral flash for code and data. The ADC on provides 14-bit, 1MSPS 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 0V 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. Application includes optical networking.

• Typical ADC power-up time is 5µs (AVDD=IOVDD=VDD1=2.9V to 3.6V, -40 to +85°C)
• Maximum data rate is 1MSPS (AVDD=IOVDD=VDD1=2.9V to 3.6V, -40 to +85°C)
• Typical input buffer off is ±200µV (AVDD=IOVDD=VDD1=2.9V to 3.6V, -40 to +105°C)
• Typical peak harmonic or spurious noise is −88dB (AVDD=IOVDD=VDD1=2.9V to 3.6V, -40 to +85°C)
• Fully differential and single-ended modes, AVDD and IOVDD monitors
• 4 IDACS with a range of 0mA to 150mA outputs, voltage comparator
• Serial wire port supports code download and debug
• Trimmed on-chip oscillator (±3%), external clock source up to 80MHz
• 96-ball chip scale package ball grid array [CSP-BGA]
• Temperature range from -40°C to +105°C
