ADuC7019/20/21/22/24/25/26/27/28
GENERAL DESCRIPTION
The ADuC7019/20/21/22/24/25/26/27/28 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 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 V to V
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. 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 ADuC7019/20/21/22/24/25/26/27/28 are available
in a variety of memory models and packages.
