ADuC7019/20/21/22/24/25/26/27
GENERAL DESCRIPTION
The ADuC7019/7020/7021/7022/7024/7025/7026/7027 are fully
integrated, 1 MSPS, 12-bit data acquisition systems incorporat-
ing 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
only available on certain models (ADuC7020, and ADuC7026).
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 modes. The ADC input
voltage is 0 to V
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. 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 I
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
ADuC7019/7020/7021/7022/7024/7025/7026/7027 are available in
a variety of memory models and packages.
