ADuC7128
GENERAL DESCRIPTION
The ADuC7128 is a fully integrated, 1MSPS, 12-bit data
acquisition system incorporating a high performance multi-
channel ADC, DDS with line driver, a 16/32-bit MCU and
Flash/EE Memory on a single chip.
The ADC consists of up to 10 single-ended inputs. The ADC
can operate in single-ended or differential input modes. The
ADC input voltage is 0 to VREF. Low drift bandgap reference,
temperature sensor and voltage comparator complete the ADC
peripheral set.
The ADuC7128 also integrates a differential line driver output.
This line driver transmits a sine wave whose values are
calculated by an on chip DDS or a voltage output determined by
the DACDAT MMR.
Preliminary Technical Data
The device operates from an on-chip oscillator and 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, 16/32-bit RISC
machine, offering up to 41 MIPS peak performance. 126k Bytes
of non-volatile Flash/EE are provided on-chip as well as 8k
Bytes of SRAM. 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 and JTAG serial interface ports while non-
intrusive 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 3.0V to 3.6V and are specified over an
industrial temperature range of -40°C to 85°C. When operating
at 41.78 MHz the power dissipation is 150mW. The line driver
output if enabled consumes and additional 30mW.
