It integrates a 16-bit (14-bit accurate) multichannel successive approximation register (SAR) analogue-to-digital converter (ADC), an ARM Cortex-M3 processor, eight voltage output digital-to-analogue converters (VDACs), six current output DACs, and flash/EE memory.
The microcontroller supports a variety of communication peripherals, including UART, two I2C, two SPI, 28 general-purpose input/output (GPIO) ports, and pulse-width modulated (PWM) outputs. The ADuCM310 has 256 kB of nonvolatile flash/EE memory and 32 kB of SRAM integrated on-chip.
The VDACs, which are 12-bit string DACs with output buffers capable of sourcing between 10mA and 50mA, are all capable of driving 10nF capacitive loads.
The ADC, IDACs, and VDAC circuits use a precision 2.5V, on-chip reference source to ensure low drift performance for all of the peripherals.
A 16MHz on-chip oscillator generates the 80MHz system clock, which internally divides to allow the processor to operate at lower frequency to save power.
The microcontroller includes three general-purpose timers, a wake-up timer (which can be used as a general-purpose timer), and a system watchdog timer.
It is available on a 6mm × 6mm, 112-ball CSP_BGA package and is specified over a temperature range of ‑10 degrees Celsius to +85 degrees Celsius.
