The ADuC7128/ADuC7129 are fully integrated 1 MSPS, 12-bit data acquisition systems that integrate a high performance multichannel analog-to-digital converter (ADC), DDS with internal line drivers, 16-/32-bit MCUs, and Flash/EE memory on a single chip.
The ADC has up to 14 single-ended inputs. The ADC can operate in single-ended mode or differential input mode with an ADC input voltage range of 0 to VREF
。 A low drift bandgap reference, temperature sensor, and voltage comparator complete the ADC's peripheral setup.
The ADuC7128/ADuC7129 have an integrated differential line driver output. This line driver sends a sine wave whose value is calculated from the on-chip DDS or a voltage output determined by DACDAT MMR.
These devices generate an internal high-frequency clock signal of 41.78 MHz through an on-chip oscillator and phase-locked loop (PLL). This clock signal is relayed through a programmable clock divider, where the MCU core clock operating frequency is generated.
The microcontroller core is ARM7TDMI®, a 16/32-bit reduced instruction set computer (RISC) with peak performance up to 41 MIPS. 126 kB non-volatile Flash/EE and 8 kB SRAM are available on-chip. The ARM7TDMI core treats all memory and registers as a linear array.
The on-chip factory firmware supports serial online download via the UART serial interface port and non-intrusive emulation via the JTAG interface. These features are integrated in the low-cost QuickStart™ development system that supports this MicroConverter® family.
These devices operate over a voltage range of 3.0 V to 3.6 V and are specified over the industrial temperature range of −40°C to +125°C. It consumes 135 mW at 41.78 MHz operation. When enabled, the line driver output adds an additional 30 mW of power.
