The is a fully integrated 1MSPS 32-bit Precision Analog Microcontroller incorporates high performance multichannel ADCs and flash/EE memory on a single chip. The ADC consists of up to 8 single-ended inputs. The ADC can operate in single-ended or differential input mode. The ADC input voltage is 0V to VREF. A low drift band gap reference, temperature sensor and voltage comparator complete the ADC peripheral set. Depending on the part model, up to four buffered voltage output DACs are available on-chip. The DAC output range is programmable to one of three voltage ranges. On-chip factory firmware supports in-circuit serial download via the UART or I²C serial interface port; nonintrusive emulation is also supported via the JTAG interface. These features are incorporated into a QuickStart™ development system supporting this MicroConverter® family.
