GENERAL DESCRIPTION
The ADuC7128/ADuC7129 are fully integrated, 1 MSPS, 12-bit
data acquisition systems incorporating a high performance, multi-
channel analog-to-digital converter (ADC), DDS with line
driver, 16-/32-bit MCU, and Flash/EE memory on a single chip.
The ADC consists of up to 14 single-ended inputs. The ADC
can operate in single-ended or differential input modes. The
ADC input voltage is 0 to VREF. Low drift band gap reference,
temperature sensor, and voltage comparator complete the ADC
peripheral set.
The ADuC7128/ADuC7129 integrate 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.
The devices operate 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
reduced instruction set computer (RISC), offering up to
41 MIPS peak performance. There are 126 kB of nonvolatile
Flash/EE provided on-chip, as well as 8 kB 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 serial interface port, and 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 3.0 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 135 mW. The line driver
output, if enabled, consumes an additional 30 mW.
