Precision Analog Microcontroller, 12-Bit Analog I/O, ARM7TDMI® MCU
The ADuC7019/ADuC7020/ADuC7021/ADuC7022/ADuC7024/ADuC7025/ ADuC7026/ADuC7027/ADuC7028/ADuC7029 are fully integrated, 1 MSPS, 12-bit data acquisition systems incorporating high performance multichannel ADCs, 16-bit/32-bit MCUs, and Flash®/EE memory on a single chip.
The ADC consists of up to 12 single-ended inputs. An additional four inputs are available but are multiplexed with the four DAC output pins. The four DAC outputs are available only on certain models (ADuC7020, ADuC7026, ADuC7028, and ADuC7029). However, in many cases where the DAC outputs are not present, these pins can still be used as additional ADC inputs, giving a maximum of 16 ADC input channels. 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.
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.
The devices operate from an on-chip oscillator and a 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 RISC machine, which offers up to 41 MIPS peak performance. Eight kilobytes of SRAM and 62 kilobytes 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 UART or I2 C 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 parts operate from 2.7 V to 3.6 V and are specified over an industrial temperature range of −40°C to +125°C. When operating at 41.78 MHz, the power dissipation is typically 120 mW. The ADuC7019/ADuC7020/ADuC7021/ ADuC7022/ADuC7024/ADuC7025/ADuC7026/ADuC7027/ADuC7028/ ADuC7029 are available in a variety of memory models and packages (see Ordering Guide).

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The QuickStart and QuickStart Plus Kits for the ADuC702x Precision Analog Microcontrollers feature debug via UART and an assembly & C-source debugging environment. In addition the QuickStart Plus Kit allows true non-intrusive JTAG emulation. You may who already have this emulator if you have evaluated other ADuC parts from Analog Devices. These kits are intended for any new users who want to have a comprehensive hardware development environment.
ADI also provides a MiniKit. This kit is ideal for system prototyping, student projects or university labs.
