The ADuC7120/ADuC7121 are fully integrated, 12-bit, 1 MSPS, data acquisition systems incorporating a high performance multichannel ADC, 16-bit/32-bit microcontroller unit (MCU), and Flash?/EE memory on a single chip.The analog-to-digital converter (ADC) consists of eleven single-ended inputs for the ADuC7120 (seven single-ended inputs for the ADuC7121) and two extra differential input pairs. The two differential input pairs can be routed through a programmable gain amplifier (PGA). The ADC can operate in single-ended or differential input mode. The ADC input voltage is 0 V to VREF. A low drift band gap reference, temperature sensor, and voltage comparator complete the ADC peripheral set.The ADuC7120/ADuC7121 provide five current output digital-to-analog converters (DACs). The current sources (five current DACs) feature low noise and low drift, high-side current output at an 11-bit resolution. The five current digital-to-analog converters (IDACs) are as follows: IDAC0 with 250 mA full-scale (FS) output, IDAC1 with 200 mA FS output, IDAC2 with 45 mA FS output, IDAC3 with 80 mA FS output, and IDAC4 with 20 mA FS output.The ADuC7120/ADuC7121 also contain up to 12 voltage output DACs. The DAC output range is programmable to one of three voltage ranges.The devices operate from an on-chip oscillator and a phase-locked loop (PLL) generating an internal high frequency clock of 41.78 MHz (UCLK). This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an ARM7TDMI?, 16-bit/32-bit reduced instruction set computer (RISC) machine, which offers up to 41 MIPS peak performance. 8 kB of SRAM and 126 kB of nonvolatile Flash/EE memory are provided on chip. The ARM7TDMI core views all memory and registers as a single linear array.On-chip factory firmware supports in circuit serial download via the I2C serial interface port; nonintrusive emulation is also supported via the JTAG interface. These features are incorporated into a low cost QuickStart development system supporting this MicroConverter? family.The devices operate from 3.0 V to 3.6 V, and they are specified over the ?40?C to +105?C industrial temperature range. The IDACs are powered from a separate input power supply, PVDD. When operating at 41.78 MHz, the power dissipation is typically 120 mW.
