ADuC7120/ADuC7121

Data Sheet

GENERAL DESCRIPTION

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 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.

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 V_REF. A low drift band gap reference, temperature sensor,

and voltage comparator complete the ADC peripheral set.

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 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 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, PV_DD

When operating at 41.78 MHz, the power dissipation is typically

120 mW. The ADuC7120/ADuC7121 are available in a 108-ball

chip-scale package ball grid array [CSP_BGA].

The ADuC7120/ADuC7121 also contain up to 12 voltage output

DACs. The DAC output range is programmable to one of three

voltage ranges, which are listed in Table 42.
